Android tablet vs YouTube Answered

Fewer and fewer YouTube videos (such as those embedded here) are working on my Android tablet. I'll see the usual frame image, but as soon as I hit play, more and more of them just become black rectangles. It's not the videos themselves, as they play on a Windows netbook or an iPod, or in the Photon browser I just downloaded. Has YouTube changed the way it plays videos,  or has Android been updated in a way that is not YouTube friendly? I want to keep using the Android browser, rather than the Photon, partly because all my bookmarks are in the defsult browser, and partly because Photon is horrible to use.

How to rip/download movies from Lovefilm? Answered

Basically you can stream Lovefilm movies online and I wanted to know, if it is possible of course, how to rip/ download streaming movies and tv episodes from Lovefilm to my computer for some offline watching. Not 100% percent how this works, suppose it's not your usual online video streaming, like the one you get from youtube, so that I could rip/ download lovefilm movie streams with just about any video downloader program. Might just be wrong, but anyhow would appreciate your suggestions.

Video in the ads is killing my bandwidth!

I know instructables pays the bills with targeted ads. That's cool, and useful. No problems there. The problem is putting a 5 minute video in the ads. That gets downloaded when I look at an Instructable. I'm on a satellite link, and my bandwidth costs me quite a bit. If I'm going to have to pay to download a video to look at an Instructable, I either won't look at it, or I'll install ad blocking software. If I want to look at videos I'll go to Vimeo, or YouTube.  Don't let poor choice in ads drive away the users.

How to disable this openDNS thing?

I'm using a Mac. So, every time I open a website like twitter and youtube and facebook, openDNS always blocks it. It redirects it to a website (block-websites.com) and I'm not sure why this is happening. Just a minute ago it was okay. I left it like for only 30 minutes (didn't shut it down) and then when I try restarting my Safari, I could not access these websites. Before I left it, I could open it. The only thing I did is to open some youtube videos and download "genio" (not sure what it is) and installed it and then uninstalled it. why is this happening? and how to fix this? Thanks (:

A new idea for the video section

Hello all, I have noticed that you can't upload WMV or AVI etc. format videos for the video section of instructables. Do you think that it is a good idea to make a video format like those of Youtube or Metacafe flash windows? I don't know exactly what to call them, but if you had an instructables account, it would be a good idea to be able to upload as ifyou were on youtube. Thoughts? You could also upload them into the everyday instructables instead of having to download them and watch them on Windows media player of the Mac equivalent. If you don't know what I mean, please ask and I will try and explain further.

Someone is passing off their 'featured' instructable as their own work :(

Hi,  I wrote a tutorial a few years ago and popped it on youtube with a link to download the supporting files. It looks like one of the instructable 'authors' has taken my code, complete with stupid comments and popped it on here as their own work. I'm not worried about someone building on top of what I made but they appear to be offering little in the way of help to the people asking questions about the instructable and asking for people to vote for them in a challenge?  Taking it, improving it and citing the source would be fine, or even taking it and citing the source but this seems to be straight out 'here's some code I wrote' Is there a way to lodge a complaint about this sort of stuff other than emailing info@ Thanks

ISP's an their sneaky ways of limiting your internet to a crawl

With more and more restiction hitting internet users I though I write a bit about the methods used to make our life harder than necessary. First example: Heavy gamer... Some people love their Xbox or PC for only one reason, online gaming. Too bad when all of a sudden your ping rates go sky high or the chat has a lag making good conversations during the game impossible. Second example: Streaming media... People like to watch what they want and when they want. Online streaming is a good way to get the latest trailers, catch up with your favourite shows or just to kill some time. Too bad when you notice the connection takes forever and that you can only watch in low quality without running into buffer problems. Last but not least P2P.... Although used for mainly illegal stuff, P2P is still not dead. A lot of software and even collections of documents are shared by the use of various P2P networks. Torrents are the most common ones but it really does not matter once your ISP has hit you hard. So what have all these in common when we speak about ISP troubles you might wonder? Well, firstly they cause a lot of traffic and secondly a large number of connections at the same time. Why would my ISP limit me? 1. You are using your internet for illegal downloads. Although in many cases the ISP won't be able to tell what you are downloading, but they can clearly see the volume of the downloads and that a P2P system is used. Does not take a genius to realise several GB a week on a constant base can't be all legal. 2. Cheap ISP A lot of our providers rent their bandwidth from another provider. This way they can provide cheaper prices but have to make sure not go over the allowance as it would could dearly. A good way of preventing this is to limit speed during so called peak hours - basically whenever a lot of people are online. 3. Your area.... Let's say you are living in a densly populated area. There you often have a single exchange for all internet and phone users. Although the numbers of possible users can be increased by adding more hardware, the bottleneck is the feed to this exchange. As they are owned by a single provider and every other ISP has to pay for the use it becomes clear that this provider will have the best speeds and traffic allowances for the people connected. In return the other ISP(s) will be reduced in speed and sometimes even the type of connection possible, for example blocking all P2P traffic completely. How do I find out what is happening to me? This is indeed a hard one! No ISP will tell you "Yes, we limited you to xxxx and these services are not working on your connection: ...." Their fineprint states you have internet and Email, depending where you are maybe online TV services. But this is only true for standard ports and protocols used! So for your favorite online game it might be possible to download the latest update in the GB range within minutes but still encounter a massive lag during the play sessions. Similar story for low speeds. It is common practise to prioritise traffic to local speed testing servers. This means no matter what "problem" you might have all test will give positive results. So you might be able to get high speeds in your tests but watching a Youtube video can mean to first buffer the entire video before you can watch it. You ISP won't support any requests as long as common speed tests work fine for you. A sure way of testing is to download a Linux distribution from a remote server. How long does it take to download? Now do the same using a P2P download of the same distribution. Did it take much longer or did you have problems connecting to peers? If so you are limited by your ISP. Be aware that this might be true for only one type of P2P network, while others are uneffected. For games check your Ping times against ping times done manual against a known server, for example Google. If they are close all is good, if the game ping is much higher (often in the thausands compared to around 300ms max) you are sucked into limitations. Ok, I am fairly sure I am limited by my ISP, is there anything I can do? If you mainly use the internet for illegal downloads you might want to consider going the legal way. For all others, check below. Main reasons for limits put on your account or connection are congestion (nothing you can do about except trying the ISP that owns your phone network and to pay more - and of course the amount of connections you make. Let me give you an example: Downloading a huge file from a server usually needs a single connection on port80. Doing the same using P2P services requires a lot of simultanious connections to many servers/PC's around the world. Only with enough, fast connections your download will progress at good speeds. You ISP can see the number of connections and cut them at a limit or completely disable the protocol used for the download. The result is crawling speeds for the download and you only see a few peers available. Multiplayer games often use several ports for the traffic, game status, chat, graphic updates like location of other players and so on. So if you play in a world with 8 of your friends and fight against 200 online players all these infos has to get to your system. Having a few kids all enjoying different online sessions at the same time certainly does not help either. ;) Unless you are permanently limited there are a few options to make things better: 1. Limit yourself to the off-peak times for big downloads. 2. Try to avoid multiple game sessions and downloads from a single internet connection, e.g: let the kids play with one console at a time. 3. Change the ports used by your program, sometimes the standard ports are used by everyone else around, changing them gives the ISP the option to spread the load. 4. Last and best option: Limit the amount of allowed connections. For games this is not always possible but for other services it is. Imagine your P2P program using 300 download sources at the same time. Every one has the actual data and a lot of other informations to transmit while your system has to send the receiving info to every single one. On top of all that you have the informations needed to find new peers, coordinate the parts and so on. You can limit those in the settings of the program. So instead of allowing 500 or more connections at the same time go down to 100 or less. Instead of allowing 100 half open connections (used to negotiate the download for a new peer) go down to 20. And of course limiting your own upload and the connections used for it does help a lot. Myths and alternatives.... You might have heard the things like "protocol obfuscation", "port hoppers" and similar exist, same for the "Tor" network and maybe even the "usenet". The myth behind all of them is the claim that oyur ISP won't actually see what you do and what your download. On top of that you have so called "VPN' services. Although some of the services will help you to overcome certain limits it does not change the fact that you ISP still can see your up- download volume and the number of connections in use. And trust me, they are not dumb either, so they will know anyway that you mostly use the internet for illegal downloads. After all, what reasons could you have to use encrypted services or to direct your traffic over VPN networks? Of course being in China or similar countries is a different story due to gouvernment restictions on the internet. As long as you do direct download with only a hand full of connections you should be fine, for everything else it comes down to luck. Protocol obfuscation worked for a few months until ISP's fixed it. The usenet might be an alternative but not for everyone. Even the famous Tor network or dedicated VPN services won't help you once your ISP got you flagged. The will simply limit everything besides standard protocols and ports, so you can use you Email and surf the net, even download directly for a server but everything else might be crippled. As I said earlier there is no way for the user to truely check what limits he has or what ports and protocols might be affected - you ISP won't tell you either. Before you get trapped into a new contract because your ISP is no good turn off all P2P and gaming for a day or two. Try again at night times after a reset of your modem/router. Quite often you will see it works just fine for a while. If so you can limit yourself, use off-peak times and so on. Sometimes it also helps to simply limit the download speed itself. Of course the best alternative is not to use illegal downloads and to seek local content for game servers or online video.

Free Music or a Way to Get iTunes into Final Cut Express? Answered

This is one of my major pet peeves. I'm growing tired of searching for back ally sites to convert music from one source (ie YouTube) to MP3 files, then download it (with a free virus as a bonus), all to get a song I already bought on iTunes into my videos! iTunes makes it impossible for anyone to do anything with their songs other then listen to them on ipods, which I don't even do. Personally, I think it's silly that I can't do anything with the songs I bought, it's a terrible waste of money.So, does anyone know how to bypass this, or know of another converter site. The one I used is no longer working. I'm making a video for AV class, but it won't be very effective without the music. Don't reduce me to recording the music off of my laptop speakers with a camcorder!

Help

Hello,I'm Marcin from Greece. I saw yesterday a video about a interactive speaker cloud,but is too expensive for me.I started search about how to build one and I saw Arduino think. (I don't have any experience about it but with instructions I believe I can make it for my nephews) That is my project: I think to use led lights and speakers 2.1. I want to sync the woofer with a specific led strips that gonna make a bright white/light blue light when a loud lighting strike hits and then the following sounds that happens at lower volume to light up the others leds,and some times some random lightening lights. All of those thinks to sync with a sound effect of raining and storm that I will download from YouTube and can play for 1 hour and more. Maybe inwill use ceiling power supply so please someone tell me if that is possible to me to make it and how much gonna cost and if anyone can guide me about what I will need and the commands.Please if anyone can,really I want to make it for the kids because they love it when is raining and hear strikes.Love from Greece.SORRY FOR MY ENGLISH.

Available ONLINE: 09/27/08 Tesla: Totally Awesome! HISTORY HACKER show

THIS looks interesting ! By Helen A.S. PopkinMSNBCupdated 9:05 a.m. ET, Fri., Sept. 26, 2008Circuit-bending YouTube star Bre Pettis doesn't want you to know that before making his History Channel pilot, he hadn't seen The Prestige.It's not that he purposely failed to catch Chris Nolan's 2006 adaptation of the steam punk novel about rival magicians starring Batman (Christian Bale) and Wolverine (Hugh Jackman).It seems Pettis never got around to it. And by the time he started putting together History Hacker, premiering tonight at 8 p.m. and midnight, it was too late. ...At the turn of the century, electricity was magic, and really, it still is today, Pettis says."This (TV show) is for all the curious people out there who want to learn about the electricity that comes out of your wall. You can run a hair dryer from the electricity in your wall generated from a power plant far, far way. That blows my mind."...Here in the 21st century, Thomas Edison is the go-to guy when most people think of electricity. No wonder, given Edison's gift for self promotion and that he'd go so far as to electrocute kittens in public demonstrations meant to discredit Tesla's AC electricity in favor of his own DC current. (True story!)The LINK is HERE :-) To watch the entire show download from here.... be forewarned, it is REALLY long....

Oculus GO - The little sideloading guide

It seems making an Instructable these days requires lots of pictures, detailed steps and tons of instructions.So before I try to paste my attempt here, I will point something out for the support team:1. There is little point in including pictures of a VR headset or how to plug a USB cable in. Same for images showing a DOS window and the command typed in it - they are the same as in the instructions...2. With little to no option to create an Instructable that requires actual code usage and properly embedded picture, let alone good editing options: How do you suggest one would accomplish this taks?3. With no category to post such Instrucables it is my personal opinion that these catergories need quite some updates! They are still the same as years ago despite life evolving around it...If you just went into the mobile VR world then you might feel a bit restricted compared to what you know from your smartphone.Over the months firmware updates provided us with some much needed things but a bit is still left out. In this Ible I will try to show way to get a bit more out of your GO. Be aware that a lot of it still requires a bit of manual work and a computer.If you are just curious then please read on and you might still find something interesting that you did not know yet.Getting started...One thing we certainly need is a way to access the GO and to install additional apps on it that are not available in the store.For this we need to activate the developer options. Unlike your normal Android device this step works only from the device you paired with your GO. Go into the settings and there look for the developer mode. Once you try to activate it Oculus requires you to sign up for a developer account. All this of course needs to be confirmed through Email activation, you know just to make it complicated and get more info about you ;) From there it is straight forward and like on any Android. Activate USB debugging, pair with your computer by USB cable and on the GO authorise the connection. Please also tick the box to make this permanent as otherwise you will be prompted every time. In case you are not so familiar with this just Google how to use ADB on Android - it is simple. I will add the required files and drivers in a later step dedicated to it.If you need more help getting the right options done or where to find them, please consider the great help for this offered on the Oculus developer sites. It makes sense to spent some time there as you find a lot of good info that might come in handy once you really want to get serious.ADB - A must have...You will find the drivers and all, as said, a bit later. ADB is the Android Debug Bridge. It allows us to get access to the (user)available file systems, do some basic tests and if supported even flash a firmware or make a backup.If you already used ADB for another Android device then you will only need the drivers for the GO. Otherwise you need to set up the enviroment for the Debug Bridge first. In the downloads will be a simple installer for this purpose. It is vital that you authorise your computer on the GO, best to tick the box to make it permanent.If you open a command prompt where you have ADB installed you can do some simple tests. Setting all required paths and system variables in Windows would allow you to access ADB functions from any folder on your computer. The later might be easier if you do not want to copy all related files into your ADB folder. Makes no real difference though and is up to your preferences.The command ADB devices should show you now that your GO is connected by listing it. If nothing shows up then please check the USB debugging option is set in the developer options. A reboot might help too in some cases. With this sorted we are good to go, almost at least...How to install "unknown" apps?As you might have noticed there is no playstore and all available stuff in the official store is VR based.Getting some essential apps on it seems to be impossible.Again the help offered by Oculus in the developer sections is a vital source, so please don't be afraid to read there ;) There are two basic ways of doing things on a device with so many restrictions.1. Just use ADB install packetname Where packetname is the filename for the app in question, for example Netflix.apk. With all apps you need in one place this is quickly done.2. Use a dedicated app installer or manager for the job. I will include one that actually works with the downloads. Same fore more detailed instructions.The thing is though that only apps designed and signed for VR will show up in your normal launcher. All other (supported) Android apps will show up in "unknown sources" in your library. Apps not supported for this purpose won't show anywhere! For them you need a dedicated launcher, which will be placed in the "unknown sources" section ;)Why do I spoon feed you here you might wonder? To be honest: If you already read some terms and basics it will be much easier to remember. Repetition is the key ;) I see little point in providing a simple to follow list of intructions as a week later you would struggle to do it again without the list in front of you.Our first unknown apps!Deciding what you might need in apps is one thing, knowing in what order you can safe hours of your life is another. I simply don't think you want to juggle with ADB whenever you want a new app that is not available in the official store. So for starters we will need something that is able to install apps for us. And since we can't use it without something to find and start it we also need an app starter. Basically like HALauncher for Android TV.The detailed instructions for this can be found with the downloads. First the app starter is installed, it will provide us with a living room like view onto a big screen. On the screen you will find all apps that are otherwise invisible to you. Some might tempt you to try them out - just don't! Unless you really know what you are doing you have a good chance to do something bad. Use the apps you know and the apps you added but none of the tempting system apps you might see.The APK installer will show up there too and is used to make installing apps a bit easier. You can copy them now onto your GO's internal storage and use the app installer to install them - how easy is that? Another option I included is the Aurora store - a fork of the YALP store and able to work without any playstore requirements. Downside is that the VR controllers are not fully supported yet as it is more aimed at TV sets. A BT touchpad works though if the controller or a gamepad fail. I only included Aurora as it could be a nice alternative one day with full VR support. Just search or browse for all the apps available in the playstore and install what you like. Be aware though that not everything will work with the remote. Some games and apps can be operated with a game controller though.It is getting nicer already ;)By now you might have already installed some things as you just could not wait to skip to the downloads.Well, can't really blame you, can I?Anyways, we now have the option to install more apps that we know from our non-VR Android devices. Oculus might make it harder in the future though - or they see it the same way and offer ready to go options one day. Till then it is up to you....Youtube VR might be nice but it is also still quite buggy and lacks some basic features. So getting a modded Youtube app could be a way out if you need comments for example. Kodi is still a must have for many Android users, especially the sport nuts with us. A filemanager is also something most Android users value. I will include some but again it comes down to what YOU prefer here. And with a basic way to install apps now you can also remove them again if you decide they don't work as expected.Get a bit used to the app launcher and how to install apps. Sideloading is fine for those used to it but some might prefer to just copy some apps on the GO and them use the installer with the remote. In the near future we will get support for external sorage, so using a USB stick or SD card in a reader will make the USB cable obsolete for file transfers. Some headsets already support it, so chances are by the time you read this yours will too. Although it still is a good way to keep your GO charged while copying big files ;)Precautions and Words of WisdomIt all sound nice and easy now but there are dangers you need to be aware of! Installing apps or games that are not fully designed for the GO or VR use can mean crashes. A lot will work but that does not mean it will keep doing so. A firmware update could one day end the support for sideloaded apps that are "non-VR". Especially messing with the app launcher can mean sudden disaster. Things you normally can not see are often hidden from you for a good reason. I will take no responsiblity for problems you caused by misusing system apps !Console emulators are a lot of fun and there are ways to even stream them from your PC in reasonable quality on a low end computer. But these and some demanding games also cause a lot of CPU usage. As the system is not optimised for 2D content it can mean that your battery runs out faster. In some cases you might not see the warning to charge, so be aware of time when immersing yourself.Stay away from any app or game that requires playstore components! Play Games for leaderboards might be no issue, especially if you don't need this feature. Online gaming like multiplayer actions will not work if it requires Google services for it! Similar story for hardware you don't have. If it is only designed for touchscreens than it might not work with the remote. And if it does not support gampads either... Apps that only support the wrong display orientation are a no go too.What Non-VR Stuff Actually Works on the GO?A lot and it will be possible to do even more. There are already streaming options for your own videos like Skybox, Moonplayer and they all support DLNA servers too. So watching normal, 3D or VR movies from a media server is no problem at all already. Getting games to work is another story all up. ALVR is a good platform to stream VR games from your PC to the GO. Unlike the Rift you won't even need an overpowered gaming PC for it. Virtual Desktop is a paid app but well worth the money if the support and features keep going as they do right now. With it you can use your computer or laptop from the GO. Watch movies, surf the net, play games. The GO more or less becomes a normal Windows computer only that you have the screen right in front of you.It will certainly be possible to code a simple VR app that works as a shortcut for non-VR apps. Like how right now you get the pic and description for a VR exerience and a button that starts the stream in the player. Downside is the requirement to certify such an "app" to make it visible in the normal launcher.Downloads and Instructions....Finally you get to the point where you can actually download something :)To make it all a bit easier and to ensure I won't miss a vital bit I did a factory reset on my GO to start from scratch :(Things might change in the future, so I will include the instructions as texfiles with the download.If I see a real requirement for screenshots I will include them with corresponding filenames.I think this way it is easier than scrolling through an Instructable as you can just print it all directly.Those without an account (yet) might value this too.Based on the feedback, questions and general comments I will change the contents of the download accordingly.Same for download links to avoid bloating up the download with outdated files.Easier for you (if you read this a few months from now) to download the newest files directly from the source.So don't be too disappointed if the download seems to contain less than what you expected.What seems to be missing will have links in the instructions.No files will come from unverified or unsecure sources!Whatever I include in the downloads directly will be checked for malware of all kinds.The same standards are true for the sources I provide.So no clickbait, ad sponsored re-directors or such crap.Please read the detailed instructions carefully, then read them again while actuall following the steps on your GO or computer.Do not blindly read it and jump onto doing it the first read!For ADB commands just copy and paste them - I might write some batch files though, so check for them in the instructions and make use of them.Things might not work out as planned, so if in doubt double check all the steps taken.What is in the provided instructions is tested on my GO's and works on the firmware version current of this writing.Download the guide and files from FilefactoryIn case the PDF in the download is not detailed enough, just ask in the comments ;)

Featuring Guidelines

Having your Instructable featured means you are an excellent author, and you're providing some of the best content on the site. We want everyone to see what you've made! When we feature your Instructable, it's our way of saying "You are awesome, and we love you!"So what does it take to get your Instructable featured? Read on, my friend, you have come to the right place! You can also check out this handy Instructable that will walk you through posting a Feature-Worthy Instructable. There are currently two tiers of featuring we use to promote great content and reward our awesome authors: Feature: Your Instructable will appear in the Featured Feed. Homepage Feature: Your Instructable will appear in the Featured Feed, as well as on the homepage.For an Instructable to be featured, the main criteria we look for are excellent documentation and reproducibility. These break down into the following points: The title fits and explains the project. The introduction should state what the project is, and the reason or motivation behind it. All photos should be original, bright, clear, and in-focus. Projects should be broken into enough steps to be easy to follow, with sufficient photos and explanatory text to allow the reader to understand the process. Grammar and spelling should be good enough so as to not be distracting. Projects should be complete and contain all the information needed so others could reasonably duplicate the project (if the reader were to have the necessary skills and access to similar tools and materials.) Lists should be included of parts/materials/ingredients/tools used, with links to sources as needed, as well as links to references. Whenever possible, the inclusion of downloadable files, PDF patterns, and so forth is desirable. Video content (youtube videos, etc.) must be accompanied by photos and written step-by-step instructions, as outlined in the points above. For a Homepage Feature, here are some additional things we look for: Overall stellar documentation Beautiful cover images Content that is highly reproducible and has that “wow, awesome!” factor Note that high levels of ingenuity, creativity, innovation, and/or utility in a project will often compensate for various areas of weaknesses in documentation, so these criteria should be viewed as guidelines and not necessarily hard-fast rules. What about business-related content from bloggers, etsy-ers, youtubers, kickstarters, and so forth?Can that type of content be featured? Absolutely! Any Instructable that meets the criteria as outlined above and contains real how-to instructional content can be featured. If you are in this camp, it's an excellent practice to keep your ulterior motives relatively subtle. For example, some of our best authors are also bloggers and etsy-ers, and many of these authors simply include a single link to their site or store in the last step of their Instructables. This is a perfect approach that allows their projects to get as much attention as possible on the site, but also plug their commercial interests in a way that is not overbearing or spammy. Being overbearing or spammy is the quickest way to NOT being featured. Want your project featured? Sometimes it's hard to see where your project could use some enhancements! Luckily, we have some great authors that will review your project and give you feedback at the volunteer-run Clinic. Do you get featured a lot? Why not spend a little time in the Clinic and help others get to your level! :)

Hulu App For Iphone!

Big news for the iPhone and iPod touch owners! Hulu is finally developing an app for the iPhone.From cNet news...Silicon Alley Insider is reporting that a dedicated Hulu application is indeed on its way to the iPhone and should be here in just a few months.SAI says the application will work over Wi-Fi and AT&T;'s 3G network, meaning that users will be able to view programming anywhere with a fast data connection.Rumors suggesting that an iPhone-friendly version of Hulu swirled around this time last year, however, they predated the launch of the App Store, and Hulu flat-out denied that one was being worked on.This time around, though, it's far more plausible, with the upcoming iPhone OS 3.0 software update, which lets developers bake streaming media into their applications. For Hulu, this means that the advertising could be stuck into the mobile stream and that users would be able to watch videos without leaving the application.One of the things that keep this rumor from holding water is that Hulu is in direct competition with Apple's iTunes business. Users of Hulu can watch ad-supported, full-length television shows and movies on their personal computers for free, instead of paying Apple to download a copy for offline viewing.If such an app were available on the iPhone, it would also offer portable TV and movie watching, something not yet offered in Apple's own mobile iTunes app, which is limited to video podcasts. In past instances of this, the company has simply denied applications such as Podcaster from making it through the app approval process, only to launch it as a first party feature later on.On the other hand, some of Hulu's competitors have already gotten a foot in the door, including Joost and CBS-owned TV.com, which has its own iPhone application that streams in content in chunks. In addition, Google's YouTube, whose application comes preinstalled on the iPhone, has recently reached an agreement with major studios, including Sony Pictures, Lions Gate Entertainment, and CBS (publisher of CNET News), to offer visitors full-length TV shows and feature films.If Hulu can't manage to pull off getting advertisements in the stream, using this system, it would be fairly simple to force users to sit through advertisements between clips.Link.

Tracking down the speed problems on a laptop.

I've copied the conversation here so we could remove the information from the original instructable's comments.  I figure this would also be of some interest to other forum viewers who may have similar problems, or may be able to chip in. The long and short of it is, 92033 (Ed) has a refurbished laptop that takes literal hours to run a YouTube video on.  I suspect that it's due to a bottleneck with his internet connection.  Here's the conversation thus far: ---------------------------------------------------------------- 92033 (Ed): Thank you kindly for your prompt reply...appreciate it very much. I came across this site by accident in searching for something else and now I'm 'hooked' on it. :) So far I've read over 400 archived posts (whew)...as well as looking at the videos. The videos are somewhat of a problem because this new laptop only has 512 mg memory...LOOOOOng time to load. For example...to watch a SLOW 5-minute You Tube video takes 5-1/2 HOURS to load...keeps showing a couple words at a time...need to get two new memory chips to upgrade to 2gb. Thanks again...Take care. ---------------------------------------------------------------- eddems: I think you're basic download speed is killing ya, not the laptop. check you're speed at Internetfrog.com, if you see the link near the bottom for the old test, run it, I like it's graph of upload and download speed much better. ---------------------------------------------------------------- 92033: Thanks much. I'll check it out. I ordered a 1gb SDRAM Memory chip which just arrived yesterday. Hope this speeds things up a bit. ---------------------------------------------------------------- harley_rly: i hear u man, my computer is hopped up, but i live out in the sticks and have dialup...i only get 24kbps at most :( ---------------------------------------------------------------- 92033: Maybe there's hope for 'us' yet. :-) I phoned Tiger Direct to see cost of an upgrading memory chip to go from 512mg to 1-1/2gb. The guy I talked to suggested I get "PC TUNEUP 2.0" which bypasses the Windows Operating System (I'm using Windows XP Pro) and speeds up the system. I gave it a try and ordered the CD (cost $39.98 - $44.77 postpaid). It hasn't arrived yet but will let you know if it helps as he claims it will. He said that if I just ordered a 1gb memory chip my system wouldn't notice much improvement as it is, but this CD should do the trick. THEN...when I DO order the Memory chip(s) to get total of 2gb my system should zip through like a rocket with the CD just ordered. I'll let you know when I get the CD and about the results. Just hope I haven't thrown forty-five bucks to the wind. Thanks for the contact...appreciate hearing from you. TAKE CARE. ~ ED ---------------------------------------------------------------- Javin007: PC Tune-Up "bypasses the Windows Operating System?" This guy fed you a load of crap. (I work on computers for a living.) PC Tune-Up does nothing more than clean up registries, defragment harddrives (if your OS even needs it, some don't) and keeps drivers up to date (which you could do manually.) That guy's an idiot, or just a liar. Could be both. Unless you were buying PC Tuneup 2.0 from Tiger Direct, in which case we can add "sleazy salesman" to that. What are the specs of the laptop? Go to Start/Run and type in DXDIAG. This will give you a quick snapshot of the specs. Specifically, I'm curious as to the processor speed/type. For a 5 1/2 hour "load" you're more likely looking at network slowdown issues (although 512 megs for XP is WAYYYY too little. I HATE when they put PCs together like that). The RAM upgrade will show significant speed increases, but no improvement with YouTube videos or other downloads. I'm glad to see you are returning the CD. ---------------------------------------------------------------- 92033: Thanks much for your input...appreciate it very much. I checked the DXDIAG as you recommended. Here's the info on it: IBM ThinPad Laptop PC. Model # 23738TU. Intel Premium M 1.70GHZ. 512mb SDRAM Memory chip.Page File- 351mb used,513 mb available. Direct Version-Directx 9.00 (4.09.0000.0904). 512 mb SDRAM-Actual 212 Ram. AVAST Anti-Virus. MS Windows XP-PRO.. Dialup Speed-40kbps. PC2700 SDRAM 512mb Memory Chip installed. I ordered 1bb memory chip which arrived yesterday. Now I have to figure out HOW to remove the bottom of this laptop to install it...lotta small screws on it. :-) Oh, total memory shows 32mb. I don't know if this means much to you. I note your comment that the added RAM memory WONT (?) speed up loading YouTube videos? Is that correct? If so, why not? Thanks again. Take care. ~ ED ---------------------------------------------------------------- Javin007: :) At the risk of boring too many people, here's how memory in a PC works: You have two kinds of memory: RAM, and Hard Drive (technically there's three, as there's also onboard video RAM on video cards, but this is primarily used for 3D video game textures, so can be mostly ignored.) Your harddrive's read/write speed is determined by the type of harddrive it is (most are SATA now) and the rotation speed (most are 7200 RPM, though the specs for your system say yours is only 5400 RPM, but there are 10, 15, and even 20K rpm models out there that are exponentially more expensive.) No matter what, harddrive memory will always be degrees slower than RAM. RAM on the other hand is a small chunk of memory that is "temporary" memory, but very fast. Its speed is determined by the type of RAM (DDR2 being the current common one for notebooks, though DDR3 is available with some motherboards (you can ignore this, though, as you can only handle 2 gigs max of DDR with your system). The motherboard will determine the limits for the RAM that can be installed.) When running *ANYTHING* on your computer, and I mean ANYTHING, it must first be loaded into RAM to be accessed by the CPU. The computer doesn't directly access the harddrive. So this means when your operating system is loaded (Windows XP) the entirety of all running processes for the OS have to be loaded into RAM. Now, Microsoft claims that Windows XP only requires a minimum of 64 megs of RAM, but recommends 128 megs. I challenge you to find me a Windows XP system that only uses 128 megs out of the box. It's not atypical for an XP system to chew through all 512 megs of your RAM, leaving no RAM available for other applications. (Interestingly, the default setup for your laptop is only 256 megs of RAM, yet yours is reporting 512.) What happens when there's no RAM left? The system has to then start trading things into what is called "Virtual Memory." VM is nothing more than a file on the harddrive that will temporarily hold information that SHOULD be in RAM, so the RAM can load more info. For instance, say you have a process that's using RAM, but you want to watch your YouTube video. As the video is ready to play, the system will take the other process's data that's in RAM, write it to the harddrive, load your video into RAM in its place, play a portion of it, write the video to the harddrive, load the data for the process to RAM, let it run for a split second (so it doesn't lock up), write it back to the harddrive, load your video into RAM and play a short clip, etc. etc. etc. The result of low RAM on your system is that applications will open slowly (seconds or minutes, instead of instantly or a few seconds) and they will seem slow to respond, will stutter, etc. With enough RAM, your system can freely open as much as it needs into RAM, and ignore the virtual memory and all the slowdowns that it causes. Now, all of this being said, NO lack of RAM will cause a streaming video to take 5 1/2 hours to play. This is 100% going to be related to your downspeed. (Go to www.speedtest.net and post your results.) RAM slowdowns tend to be most noticeable when shutting down, or starting up your computer, apps will open a little more slowly, they will be slower to respond to button clicks, and video will be very choppy. Anything that is causing a YouTube video to take HOURS will be due to the system simply waiting to get the video in the first place. RAM wouldn't slow down the receiving of the video, but it would cause the video to play weird once it's downloaded. So, all this being said, here's the summary: Your system has a 1.7 Ghz processor, and your RAM is most likely 333 Mhz DDR. If you bump your memory up to a gig, you should see a pretty significant improvement in that your computer will, overall, just "feel" faster. It'll be more responsive, and working with large documents will be many, many times faster. This won't, however, affect your YouTube experience (unless you were getting jittery video often, not the same as "buffering" video.) If you see "buffering" for a long time, your internet connection is your bottleneck. A test on www.SpeedTest.net will likely confirm this. However, if you get decent numbers on SpeedTest, then we could have something more sinister going on, though I suspect you'll find your numbers well below the 1 mbps rate. This brings us to actually changing the RAM. I've been out of the PC hardware realm (professional programmer now) for a few years, and was unable to find a manual for your particular model. However, if memory serves, this image should be a fairly accurate representation of the underside of your system: http://www.javin-inc.com/temp/thinkpad.JPG Don't quote me, but I BELIEVE the red circle will indicate the only screw you will need to remove to access the RAM. There should also be a small clip holding the RAM in place that you'll want to pinch to get the RAM out, and make sure that the new RAM snaps into place. (Sometimes you'll have additional empty RAM beds, and you can just put your RAM in there and end up with 1.5 gigs, but I suspect you'll have two 256 gig chips in there.) ---------------------------------------------------------------- 92033: Phew. Thanks again for your most indepth educational lesson. I appreciate all your help more than you realize. I attempted to answer this last night, typing in more than twice the amount of text as your to me, then suddenly realized there was a glitch and I was on another page...lost it all into the ionisphere. :-( Rather than try to retype all I wrote, I shut 'r down and went to sleep. Now I'm trying to recall all I wrote last night but failed to get mailed. I'm not a traditional typist, rather a one-finger bloke so you can understand the frustration there. I do, however, type at a reasonably good speed. With that said, let's continue. I went to search for Configuration of this IBM Laptop ThinkPad 23738TU and am copy and pasting it here.

I'll ATTEMP to try again later. So please don't reply yet as you need to read my discoveries in changing the RAM chip. Meanwhile, thanks again...take care. ~ ED ******************************************************************************* TRY #3...I'm Back :-) Your diagram showing where the RAM chip is located was right on. Thanks. Here's my DISCOVERY :-( The RAM chip installed was NOT a 512mg...but only a 256mg chip. The ads ans specs say it's a 512mg...NOT SO. I was lied to by either the manufacturer or refurbishing company who removed the original 512 chip and reinstalled a 256 chip. I was lied to by the Tiger Direct guy on the phone. There are NOT two chip slots...only one. So I now have a useless removed 256mb RAM chip. Replaced with the 1gb RAM chip I just installed. So instead of having 1-1/2 gb RAM, I only have 1gb. Here's the crux. To. go to 2gb RAM I'd need to buy a full 2gb RAM CHIP and discard the 1gb for which I just paid $39.99 ($45.00 with s/h). This means another output of almost a hundred dollars plus the $45.00 just wasted because they wont accept return once the sealed chip plastic was opened...even though I had no idea there was only ONE SLOT in this PC instead of TWO like the Tiger Guy said. Now...crux #2...this new 1gb RAM does nothing more to increase speed. I just watched a 2.01 MINUTE YouTube video which took a HALF HOUR to load, so I threw the money away for nothing, eh? There is no noticeable change except the 'speed' shows it now as 41.2 kbps instead of 40 kbps. Okay...now HOW do I get to speed this thing up to normal viewing in real time? I also saw an ad for 4bg RAM Gateway laptop with 120gb hard drive for $404.99 which is all suped-up with everything. I had to upgrade a LOT since I got this only four months ago...taking over a hundred hours to load it, like Internet Explorer 5 to 6 and then to 8 and now to 9. I'm using AVAST Anti-Virus, after trying for 23 hours to get ADVAR, then find out it didn't load because of problem on the servor's end. Added Firefox and upgraded twice. Loaded MS Protection but it created more problems so I deleted it...now with AVAST which I like. Soooo...I've literally spent over 200 hours to get this thng where it's at now, plus the wasted money for the upgraded RAM chip.and I still don't have increased speed. HOW do I get it? IF the processor has to be changed does this mean I have to gut the thing and install a new motherboard? If so, what kind of money cost are we talking here? I bought this four months ago as a refurbished unit only because I was able to get it on payments of only $25.00 a month. If I had to wait to get $400.00 cash I'd never have it. :-) Okay...that's it for the moment. Thanks much again for your help offering and detailed instructions...appreciate it more than you realize. Best Wishes And God's Blessings To You And Yours In Everything Always. Most Respectfully... ~ ED  ---------------------------------------------------------------- Javin007: Well, let's start with the RAM. If you're running windows XP, you can assume all the extra processes (virus scanners, and whatnot) will be eating up about 512 megs of the RAM. First thing to do is check DXDIAG again (start/run) and verify that it's now reporting the correct amount of RAM. (Don't be surprised if it's like 9 hundred something megs or slightly more. It won't report 1024 or 1 gig.) This being said, that will leave you with the other 512 for your applications. This box won't be running the latest and greatest 3D games, but I suspect it was never intended to. If the heaviest hitter you'll have running is along the lines of photoshop, the 1 gig of RAM you have now should be plenty sufficient. I wouldn't worry about getting 2 gigs. Not for this rig, anyway. Also, Avast is a great (and free) virus protection, every bit as good as Symantec's Norton, so good choice there. If your youtube videos are choking out, we need to start by verifying that it's an actual speed throttling problem. Go to www.SpeedTest.net and run the speed test. Come back with the results.

iPad Problems - 14 Problems with Apple's iPad

Apple just revealed the new Apple iPad Tablet that will probably make it one of the first failures by Apple's latest line of products. Apple revealed this new Tablet PC as a challenger to netbooks. However, it's already been labeled a "less powerful, but more expensive netbook." Here are 14 iPad problems that made this Apple iPad an iDisappointment. 1. No Multitasking The Apple iPad is just like the iPhone, in that there is no multitasking. You can't work on a document and talk on AIM or Gtalk. In other words, the iPad just a giant iPod Touch (the iPod Touch being better) and cannot match netbooks. 2. It Has an Awkward Design The design is a bit awkward because you have to hold it in one hand and balance it while your other hand uses the functionality or more likely you will need to put it on your knees to use it properly. It's like holding a monitor, I'm sure nothing will happen to it. Some people complain about the Bezel being too large, but perhaps this was necessary so that you don't constantly give commands while moving around. 3. No Adobe Flash Were you considering watching Hulu on this? How about youtube (well we'll have to wait for an app for that)? Thinking of playing flash games while waiting on the bus? Oh well. 4. No USB, Need Adapters Again with the iPod design, you need to plug in the special Apple adapter. If you lose it, you'll have to buy another. If you want to plug in multiple devices you need USB to iPad adapters! Since it's not even using Mac OS, most USB devices would probably not work anyway. 5. AT&T; Once Again Are you thinking of purchasing the 3G version? You'll need to get it with AT&T; and think of how overloaded their service will be now. There is no Verizon, T-Mobile, or Sprint service available for this product, some of which has better coverage. You can't use T-Mobile's 3G at all because of their MicroSIM made specifically for AT&T.; 6. Memory Business Model Apple will charge you extra for higher memory. It's a business model they use for all their products to increase profits. That's why they don't want other storage devices being inserted to improve memory. You're also stuck with a limit of 64GB, so don't think about putting in all your music, movies, or games. 7. Touch Keyboard Many people were complaining about the touchscreen keyboard. Which would be fine if it worked perfectly and you didn't have to sit it exactly on your lap and make sure it's flat. You can however, attach an Apple keyboard, just another way for Apple to make money. 8. App Store Again Just like the iPod Touch you have to download everything from an App store. Meaning if you don't like Safari, you're stuck with it. Some apps may be banned once again. 9. No Cameras Yeah no web cams on the front, and no cameras for photos or videos from the back either. 10. No Removable Battery You can't just take an extra battery with you on a long trip because the battery works the same way as an iPod (though my bet is, it doesn't last as long). 11. No HDMI/DVI Output You can't plug this thing into your TV to display your HD movies. You'd need AppleTV for that. 12. No Widescreen 16:9 ain't happening, you're stuck with a 4:3 screen. 13. No GPS There's no GPS, so --unlike the T-Mobile MyTouch or the Verizon Droid which both run on Android, can multitask and have GPS so that you can use the Beta Google Maps Navigation system for turn-by-turn directions-- you're stuck with locating yourself via WiFi hotspots. 14. It's Large, Slow, and Clunky Not only will you have to buy accessories to protect your device, it's very large making it easy to drop and probably won't live a healthy life in a backpack filled with notebooks and other possibly sharp objects. There may be a number of accessories sold by Apple to cover some of these problems. The iPad max speed is 1GHz (A4 processor) and will probably be just as slow surfing the web as most other smartphones and it won't match up to netbooks. There is no Mac OS X or anything either, it's definitely the iPhone OS except without the Phone capability and of course I'm sure they will ban Google Voice and Skype. The iPad is about the size of a Kindle, so it is nice for reading e-books I suppose, but then I'm not sure why I wouldn't just buy a Kindle. As with all companies that initially have much success, they get a little overconfident and launch a product just to create more hype and increase their stock prices.   More related iPad Problem resources: ipad wiki - What you need to know about iPad The iPad is a tablet computer developed by Apple Inc. Announced on January 27, 2010, it is similar in functionality to the iPhone and iPod touch, running the same operating system (iPhone OS) and almost all of the same applications...

500W electric scooter control and instrumentation with Arduino mega

1. Introduction DC 500W motor control with an Arduino mega to limit starting current and to vary the speed of the scooter. The battery is in 24V, 10A.h. The following table summarizes their characteristics: https://i58.servimg.com/u/f58/17/56/35/17/a014.jpg https://i58.servimg.com/u/f58/17/56/35/17/a111.jpg 2.

Book «I realize my electric vehicle» at DUNOD 3. Open loop program To test the programming, we simulate the program in ISIS, as can be seen in the following figure. In addition, we have an LCD display to display data (duty cycle corresponding to the PWM at 32Khz, motor current, motor voltage, action on the pushbuttons, 4 push buttons are used. BP1 to manually increment the duty cycle, BP2 decrement it. BP3 set the duty cycle to 0, corresponding to the brake contact. The speed of the motor is practically proportional to the duty cycle https://i58.servimg.com/u/f58/17/56/35/17/a211.jpg We made our own current amplifier called a step-down chopper but it is possible to buy a shield There are many cards for Arduino to control DC motors especially of low powers and also of great powers as can be observed on the following links.http://www.robotpower.com/products/MegaMotoPlus_info.html http://www.robotshop.com/en/dc-motor-driver-2-15a.html https://www.pololu.com/file/0J51/vnh3sp30.pdf https://i58.servimg.com/u/f58/17/56/35/17/a310.jpg But all these chopper shields measure the current internally but there is no current limitation. In order to have a current limitation, an analog current loop is required using specialized AOP or IC or a fast digital current loop. But what should be the value of the limitation current? The choice of the current value is normally for the 1-hour operation service in order to be able to carry out relatively long climbs without reaching the critical temperature of the engine. In our case, the limitation current must be Limiting motor = Power / Upper battery = 500W / 24V = 20A In addition, the power transistor of the chopper can only support 50A in our case. But in open loop, it has no current regulation, so as not to exceed the maximum current, a ramp of the duty cycle will be used. A 0.1 second interruption routine will be used to measure the voltage of the current (sample measurement, sample). This sampling time is arbitrary but does not allow to be faster than the rise time of the current because the electric time constant of the motor is L / R = 1.5 ms. Open loop operation with a 25.5s (8bit) ramp and 0.1s interrupt routine provides a good understanding of the operation of a DC motor drive. The display will only be done every 0.2s to have a stability of the digits on the screen. In addition, a digital filtering will be done on the current and the voltage on 4 values therefore on 0.4s. [b] Algo open loop [/b] Interrupt Routine All 0.1S Read voltage and current Loop loop (push button scan) If BP1 = 1 then increment PWM If BP2 = 1 then decrement PWM If BP3 = 1 then PWM = 0 Displaying variables every 0.2s Code: [Select] // include the library code: #include #include #include #define SERIAL_PORT_LOG_ENABLE 1 #define Led     13       // 13 for the yellow led on the map #define BP1     30       // 30 BP1 #define BP2     31       // 31 BP2           #define BP3     32       // 32 BP3 #define LEDV    33       // 33 led #define LEDJ    34       // 34 led #define LEDR    35       // 35 led #define relay   36       // 36 relay #define PWM10    10      //11   timer2    LiquidCrystal lcd(27, 28, 25, 24, 23, 22); // RS=12, Enable=11, D4=5, D5=4, D6= 3, D7=2, BPpoussoir=26 // Configuring variables unsigned   int UmoteurF = 0;  // variable to store the value coming from the sensor unsigned   int Umoteur = 0; unsigned   int Umoteur2 = 0; unsigned   int Umoteur3 = 0; unsigned   int Umoteur4 = 0; unsigned   int ImoteurF = 0;  unsigned   int Imoteur = 0; unsigned   int Imoteur2 = 0; unsigned   int Imoteur3 = 0; unsigned   int Imoteur4 = 0;            byte Rcy=0 ;    // 8bit duty cycle unsigned    int temps; // the setup function runs once when you press reset or power the board void setup() {   pinMode(Led, OUTPUT);   // Arduino card   pinMode(LEDV, OUTPUT);   pinMode(LEDR, OUTPUT);   pinMode(LEDJ, OUTPUT);   pinMode (PWM10,OUTPUT);     // Pin (10) output timer2   //  digitalWrite(LEDV,LOW);   Timer1.initialize(100000);         // initialize timer1, and set a 0,1 second period =>  100 000   Timer1.attachInterrupt(callback);  // attaches callback() as a timer overflow interrupt   lcd.begin(20, 4);    Serial1.begin(9600);   TCCR2B = (TCCR2B & 0b11111000) | 0x01;         //pin 10  32khz    http://playground.arduino.cc/Main/TimerPWMCheatsheet                                                   //http://www.pobot.org/Modifier-la-frequence-d-un-PWM.html   //   analogWriteResolution(bits)      https://www.arduino.cc/en/Reference/AnalogWriteResolution lcd.setCursor(0,1); lcd.print("Rcy"); lcd.setCursor(10,1); lcd.print("Um"); lcd.setCursor(5,1); lcd.print("Im"); lcd.setCursor(10,1); lcd.print("Um"); lcd.setCursor(20,1); // 4 lines display * 20 characters lcd.print("BP1+"); lcd.setCursor(25,1); lcd.print("BP2-"); lcd.setCursor(29,1); lcd.print("BP3=0"); } // Interruptions  tous les 0.1s void callback()  { temps++; //toogle state ledv for check   if ( digitalRead(LEDV)== 1 ) {digitalWrite(LEDV,LOW);}     else {digitalWrite(LEDV,HIGH);}     analogWrite(PWM10,Rcy);   // frequency Umoteur=analogRead(A0); Imoteur=analogRead(A1); Imoteur2=Imoteur; Imoteur3=Imoteur2; Imoteur4=Imoteur3; ImoteurF=(Imoteur4+Imoteur3+Imoteur2+Imoteur)/4 ; Umoteur2=Umoteur; Umoteur3=Umoteur2; Umoteur4=Umoteur3; UmoteurF=(Umoteur4+Umoteur3+Umoteur2+Umoteur)/4 ;   }// End routine // Loop corresponding to main function void loop() {    // BP + LED   if ((digitalRead(BP1))==1) {     lcd.setCursor(20,0);      // Column line     lcd.print("BP1");     digitalWrite(LEDR, LOW);        digitalWrite(LEDJ, LOW);     Rcy++;                        // PWM incrementation     if ( Rcy>254)  {Rcy=254;}     delay(100);               //8bits * 100ms = 25S increment 25ssecond slope     }        if ((digitalRead(BP2))==1) {     lcd.setCursor(20,0);     lcd.print("BP2");             Rcy--;      if ( Rcy<2)  {Rcy=2;}  // PWM almost at 0, engine stop         delay(100);      digitalWrite(LEDR, HIGH);     digitalWrite(LEDJ, HIGH);     }   if ((digitalRead(BP3))==1) {     lcd.setCursor(20,0);     lcd.print("BP3");      Rcy=2;               // PWM almost at 0, engine stop     } if (temps>=2)  { lcd.setCursor(0,0); lcd.print("                "); // Erase line lcd.setCursor(0,0);     lcd.print(Rcy); lcd.setCursor(5,0); ImoteurF=(ImoteurF)/20;     //resistance (5/1024)*(10/0.25ohm) si ACS712 66mV/A                            // For resistance 1ohm (ImoteurF) / 20; Simulation 5/25 lcd.print(ImoteurF); lcd.setCursor(10,0); UmoteurF=UmoteurF*10/38;                              //10/38   10/30 simula if (Umoteur>ImoteurF){UmoteurF=UmoteurF-ImoteurF;  }  //U-R*I lcd.print(UmoteurF); temps=0; }// End if time    } // End loop https://i58.servimg.com/u/f58/17/56/35/17/dsc_0614.jpg Since there is a limit of 9000 characters in the forum below Open loop program feature previous The interrupt routine lasts only 250 microseconds, the loop of the main program which scans the action of push buttons is 13micros and the display time of all data is 11ms. Thus, it is possible to improve the sampling period and thus the speed of the regulation of the current. The Arduino makes it possible to make the instrumentation of the scooter so to know the power, the consumption in Ah and Wh, to measure the speed, to know the consumption according to Wh / km, to measure the temperature of the engine, Have a safe operation. But for now we will see how to limit the current 4. Closed loop program, limited current control The sampling period will increase to 0.01 seconds (interrupt routine) If the current is less than the desired value, then the duty cycle can be increased or decreased to the desired value which is the setpoint. On the other hand, if the motor current is greater than the limiting value, there is a rapid decrease in the duty cycle. So as not to exceed the value of the duty cycle if it is saturated to 254 maximum and to the minimum value 6. Code: [Select] if (Imoteur<4000)                    // No current limitation at (20A * 10) * 20 = 4000   {if (consigne>Rcy)   {Rcy=Rcy+1;}   // Pwm ramp + 1 * 0.01second pure integrator    if (consigne    if ( Rcy>254)  {Rcy=254;}           // Limitation of duty cycle    analogWrite(PWM10,Rcy);   // Frequency 32kHz timer2}         } if (Imoteur>4000)  { Rcy=Rcy-5;              // No current filtering, to be faster                     if ( Rcy<6)  {Rcy=5;}       // Rcy is not signed, nor the PWM therefore Rcy minimum must not be less than 6                   analogWrite(PWM10,Rcy);   // Frequency 32kHz timer2}                        } 5. Closed Loop Program, Limited Current Control with Acceleration Handle An acceleration handle provides a 0.8V voltage when not operated and a 4.5V voltage when the handle is fully engaged. Instead of using pushbuttons to increase or decrease the speed setpoint, an acceleration handle will be used Code: [Select] Upoignee=analogRead(A3); // The relation in Upoign and the setpoint which corresponds to the duty cycle corresponds to if (Upoignee>100) { consigne=(Upoignee/2);     //0=a*200+b    et 255=a*800+b                      consigne= consigne-100;                   }                            else { consigne=0;   }               if (Upoignee<100) { consigne=0;  }     // redundancy     6. Temperature and safety program of the motor with the current measurement The outdoor temperature measurement can be easily performed by the LM35 component which charges 0.01V by degrees Celsius Code: [Select] temperature=analogRead(A2); //lm35 0.01V/°C temperature=temperature/2;       // Temperature coefficient lcd.setCursor(5,2); lcd.print("      "); lcd.setCursor(5,2); lcd.print(temperature);   // Display in ° C lcd.setCursor(9,2);      // Erasing secu display lcd.print("     ");   if (temperature>80 ) {lcd.setCursor(9,2);         // If motor external temperature is above 80 ° C                      lcd.print("secuT");                       Rcy=0;} In addition, thermal safety by measuring the motor current will be added. If the limitation current is greater than 10s then the motor will no longer be powered for 30s. A "secu" display will appear on the LCD display. This safety makes it possible to cut the motor on slope too high and when blocking the engine but it would be necessary to add the measurement of the speed in the latter case Code: [Select] if (timesecurite>=10000 ) {flagarret=1;      // If limitation current for a current of more than 10s                               timerepos=0;                               consigne=0;                               Rcy=0;                                 timesecurite=0;}       //   Then stop engine during a downtime    if (flagarret==1 ) {lcd.setCursor(9,2);         // If limiting current for a current of more than 20s                      lcd.print("secU");  }     //   Then stopping the motor for a stop time and display                                                     if (timerepos>=30000 &&  flagarret==1) {flagarret=0;                                           lcd.setCursor(9,2);      // After a rest time here of 30s                                            lcd.print("       ");   }   The display can be observed if the temperature is above 80 ° C https://i58.servimg.com/u/f58/17/56/35/17/a017.jpg Thermal safety by measuring the motor current (digital thermal relay) which allows to know the image of the internal temperature of the engine would be ideal. But for this, it is necessary to know well the thermal modeling of the motor. 7. Measurement of the energy capacity of the battery The energy capacity of a battery is in A.H, we will display the value in mA.H to have a high accuracy. The capacity will be in A.Second in the following equation. So to have in mA.H, it will be divided by capacity by3600. Capacity (A.s) n = I * Te + Cn-1 with Te = 0.01s and I multiplied by 10 So in the interrupt routine Code: [Select] capacity=ImoteurF+capacity ; And in the display Code: [Select] lcd.setCursor(0,3); // Display of energy capacity lcd.print("C mA.h="); capacity1=capacity/(18000);   //18000=3600*5  5=> Current measurement coefficient lcd.print(capacity1); To check a current of 10A with an adjustable resistor and after 30s, the capacity must be 83mA.H 8. Power and modeling with SIMULINK Modeling helps to understand the vehicle and its control. In addition, it is possible to compile the control part directly into the Arduino program from simulation under Simulink. But it will not be possible to simulate the instrumentation with the LCD display. In the following figure, we can observe the simulation of the programming of the chopper with the current limitation with Simulink. In the following figure, the green box shows the duty cycle control to vary the speed and the red border the current limitation. The controller of the control is here a simple integrator but it is possible to carry out a multitude of control. https://i58.servimg.com/u/f58/17/56/35/17/azub_c15.jpg In the previous figure, it can be observed that the current is well limited to 25A from 2s to 9.5s. Then, the current reaches 10.8A under established speed regime at 22.5km / h. The dynamics are similar to the tests carried out. With a slope of 5%, the cyclic ratio reaches only 100% as can be seen in the following figure. The speed will reach painfully 19km / h with a current of 24A and a motor power of 580W. See article: Study of electric scooters 100W and 500W (Arduino), 9. First conclusion It is easy to control a 500W DC motor with an Arduino and some components So repair many scooters that are in DC motors. But it takes some knowledge (automatic, engine) to know how to properly manage the engine and limit its current so as not to damage it The display of the speed, the distance, the operating time to know the Watt.km / km can also be realized with a menu 2. The .ino program as an attached file, But it is not possible to put an attached file in ISIS electronic labcenter? What is this forum? It would be desirable that the compiler could generate the.cof to debug in Isis and test the program line by line .... Arduino still has to make a lot of effort to be on the same level as other microcontrollers 10. speed measurement (tachometer) Velocity measurement is carried out using a hall effect sensor SS495 or A1324 which counts each revolution of the wheel. It is enough to enter the perimeter of the wheel of the scooter (130mm of radius therefore 0.816m in the case To have the speed, it is enough just to divide the number of turn of wheel on an arbitrary time of 1s to have a minimum speed of 0.81m / s therefore of 2.93 km / h. In addition, an average filter with 3 values will be used to display the speed. At 25km / h, there will be 8.5 laps. To count the turns, an external interrupt routine will be used on input INT0 21 of the mega card. http://www.locoduino.org/spip.php?article64 To simulate the speed, a pulse on input 21 will be used with a duty cycle of 10%. https://i58.servimg.com/u/f58/17/56/35/17/a018.jpg Code: [Select] void INT0b21() {   Tspeed++;   // External interruption to count the number of turns } // In the set up declare the interrupt routine when the 5V edge of the magnet detection is done   attachInterrupt(digitalPinToInterrupt(21), INT0b21, RISING );  // External interruption // In loop if (temps09>=5)  {        // 1 second loop lcd.setCursor(13,2);      // Erasing speed lcd.print("kph     "); lcd.setCursor(16,2); speed1=Tspeed*2937;      //1tour*816*3.6/1s=2.937km/h speed2=speed1;           //Tspeed (rate/seconde) speed3=speed2; speedF=(speed1+speed2+speed3)/3000;   // To put in kph lcd.print(speedF,1);    // Display to the nearest tenth Tspeed=0;   // Reset counter temps09=0;  //reset time } To improve the accuracy of the velocity measurement, it is possible that the sampling time of the velocity measurement is dependent on the velocity. For example: For speeds less than 10km / h sample at 1second, but above 10km / h sample at 2 seconds. 11. Distance measurement for autonomy The distance corresponds to the total number of turns of the wheel multiplied by the perimeter of the wheel. So do not set the number of turns to 0 for each sample. On the other hand, the reset of the distance will be done when pressing the reset of the Arduino Mega. The distance display will be displayed to the nearest second. At 32km / h, it will take 2 minutes to do 1km as can be seen in the following figure: https://i58.servimg.com/u/f58/17/56/35/17/a019.jpg Code: [Select] void INT0b21() {   Tspeed++;   // External interruption to count speed   nbrRate++; } lcd.setCursor(13,4);      lcd.print("km      ");  // distance=(nbrRate*816)/1000;  //distance m distance=distance/1000;  //distance km lcd.setCursor(15,4);      lcd.print(distance,1);  You can observe the electrical installation with the chopper, the arduino, and the display when the program is set up https://i58.servimg.com/u/f58/17/56/35/17/dsc_0613.jpg 12. Synthesis The RAM space is used only at 4% and ROM space at 3%, for an Arduino mega. So we could take an arduino a little smaller. But, there are 8 Lipo cells to make the 24V power supply to power the engine via the chopper. Therefore, the voltage measurement of each element will be on the Arduino with a JST connector. This measurement makes it possible to know if a cell with an internal resistance which begins to pose a problem and to know if the balancing of each cell has indeed been carried out. It is possible to switch to 36V with 12 cells also with the arduino mega without using an external shield that multiplex 24 analog inputs on input A0 It is possible to send all data to a smartphone via Bluetooth HC06 via pins 20, 21, RX1 and TX1. But the application under android realized under JAVA Studio can not be shared on this forum. This part will not be explained. After having made the instrumentation of this scooter, a study should be carried out on the precision of the measurements, it is possible to read "Instrumentation of a low-power electrical motor vehicle" eco marathon "type Revue 3EI N ° 81, July 2015 http://www.fichier-pdf.fr/2015/09/07/instrumentation-vehicule-faible-consommation-eco-marathon/

Facebook and privacy in VR - on a worse level than for the social media app...

These days not just isolation drives more and more people to try VR - virtual reality.It is great fun to watch a movie on a huge screen you have on your head and even more fun to actually play games while moving around and dodging bulltes.But when it comes to the famous Oculus headsets we might have to pay a hefty price - several times....Imagine you just forked out the $400 or so bucks for their latest headset and want to get going....It is a standalone device, so how hard can it be?....Pop it on the head, turn it on and follow the instructions that shall come.Well, before you can do this you find a piece of carboard covering your lenses and if you bother to read it you are getting slightly confused - if you are privacy concious person like me.I can set up basically any Android device I like without the need to have another mobile device or computer to do so....Not with Oculus, or to be precise Facebook as the actual company owning Oculus.You first need the Oculus app - appearently because it makes the setup process soooo much easier.How does this two stage initialisation actually work and what are (with FB always) possible privacy concerns?For totally unknown reasons Oculus insist that you need location services to turn on a VR headset for the first time....Without this you won't be able to proceed.Means in reality FB gets your pinpoint home location provided, whether you want them to know or not, whether you have a FB account or not.They also need a "real" Email address.Most freemailers are rejected here, claiming they would not allow for a verification.Disposable Email providers are rejected right away.Depending on your operating system clicking on the confirmation link in your Email will then also provide vital data on the OS, device and Email client you used, and of course the browser.So far so good, or bad...With your Oculus account finally ready you can proceed and try to link your headset to your mobile device to complete the setup.Isn't it great that you can type in your Wifi password on the phone instead of using the headset?Not claiming FB does but it would be dead simply to collect that info from you as and to send it home...Unlike Google Oculusis still unaffected from authorities getting concerned about data hoarding, tracking and privacy exposure.No wonder than that your only option is to agree to all terms and conditions - for everything FB deems fit.If you actually bother to read these terms and conditions two things become clear quickly.1. You basically have to give your identiy to FB unless you cheat properly right from the start and from well before trying to pair your new gadget.2. All concerning privacy and information sharing options will be turned ON BY DEFAULT. It is quite a long process for a new user trying to find the few things you can turn off...After all this you can put the headset on and try to explore - well, not so fast please...There isn't much free content in terms of games or good experiences, so you need a payment option - a verified one....At least this option is not forced on you right away and you CAN continue without setting up a payment option.For now anyway....You are finally there, you made it and can enjoy a 3D environment for the first time!A bit of fun and help from the UI to get you going and it is time to do things...No full game of any use comes installed, so it is the first thing most new users want to try.Not much free games at all, a few Demo games, previews and the rest...Well, let's say IMHO not worth wasting time on unless you are below 13 years of age and like simple shapes.You decide on some Youtube or some of the great 360° experiences on offer and might actually waste your first charge on them.While the thing recharges you start to wonder what else you could do....You have some nice movies in your DVD collection, wouldn't it be great to watch them on the big screen?Let's just say it is quite a hassle to get a real DVD to appear on your headset and play.But things like Netflix are a breeze to set up if you already have an account.For your normal Android, PC, Laptop or MAC you find a huge amount of really good and really free video players.The VR community though is locked out thanks to the content control in the store.Most things start out "free", like Skybox once did so the users can sort out bugs, help to create something users want and value.Then the support ends and there is only a paid version available.Unlike your other devices you won't be able to use the old, free version any more, it just refuses to work.Same for all the demo and preview games, once you start to like it, it is over already.Then you need to pay to keep playing the "real" thing.Frustration sets in as you did nt really buy a 3D headset just to watch some movies and do software testing.You need to buy something to make real use out of the headset.Great thing is that you get a 14 day full refund policy - read it carefully!You basically have about one charge of the batteries to try something new you paid for.Use it for two hours and it is yours forever...Even if you wife called for dinner and you just take the headset off and trust it goes in standby.It does, but unless you used the exit button the time for your new purchase will keep running while you eat.Yes, even a blank screen is standby then counts as time you used the app or game ;)You could accept all this, considering it all new to you and just need to keep an eye or better alarm on the 2 hour mark.Oculus does not like it though if you "test" a lot of things only to ask for a refund.Try 10 or so titles on a long weekend and ask for a refund, then check the response you get for the next weekend of unseccfull testing...For many titles and apps the price is IMHO outrageous!Even things that have been free or dirt cheap for often decades are now sold at a premium.Fruit Ninja, Tetris for the price of a good steak....A $50 "Game" is played through in often less than 2 hours, after that it is the same again and again, you only get more points but won't see anything new.And then there is is this addon or parts thing....You get a free game or experience only to find that most of what you are after is available at additional costs.It is very, very easy to quickly have a collection of a few apps and games that are worth more than the entire VR set....It is a scam...There are not many apps or games to begin with and even less you could label "exclusive".Especially for the Quest and GO Oculus uses ported games and apps - often those who were available for years on their higher end platforms.Often with higher prices than anyone could understand.A port costs you next to nothing, it a more or less automated process....Many things are available with a license of sorts.Steam for example makes it quie easy to use a game you pruchased on multile platforms without ripping you off in the process.You could buy 5 Oculus VR headsets for your family to enjoy lockdown in the virtual world together...Maybe a Quest each for the parents and then some GO's for the kids?Sadly Oculus does not provide anything for owners of multiple devices, unless you mean using a high end PC to stream Steam titles and hope the thing won't start smoking.You would think that if you bought a bunch of devices for the family that you could enjoy things together with ease.Well, every app or game you need will need to paid for every single device at full price...Suddenly watching you movie collection with the family sets you back well over 100 bucks just so that everyone has a player for the movies installed.Doing some family battles in a VR game can set you back $250 with ease!Suddenly a virtual family gets really expensive, really quickly...One of the reasons you find so many second hand devices that were only in use for about a month or two until the owners gave up on VR....Let's sum up what FB does to make a lot of money and collect a potential mountain of information on you in the virtual world:You provide the follwoing freely only to get the thing running:You name and full address - the later confirmed by your GPS location.Any location you use the companion app and pair with your headset, so your firends places as you need to set up a new WiFi connection...Your personal Email address and postal address unless you bought over the counter and decided not to register your device for warranty purpose - and who would need warranty for a device only worth a few hundred bucks.... ;)To really get going you also provide the following:Your credit card details.Accepting that there is no real security to prevent your kids installing what they like in paid apps once a credit card is linked.It is possible but again not really easy and straight forward to set up.Your social media accounts - FB already has you FB account if you used the same Email Address anyway without you making it offcial on your headset.Now, I don't know about you but should I really trust a company like FB would to only the right thing with these informations?? History showed us how much we can trust FB on privacy...Any further hassles?Well, if you do have a lot on you laptop, PC or just phone you do backups, at least you should.Oculus does not really provide such an option.So once you storage space runs out, and it can do so quickly especially on the 64GB models, you need to delete things.Appearently once you bought a title it is your to keep and you could, in theory, just download and install it again - once you deleted other stuff....You can't even connect to any cloud services or network storage you have for this.You need to constantly charge or use a cable with a battery pack/charger.I could not finish a 2.5 hour 3D movie on a single charge....What about community projects?Be it Playstation, Nintendo or just plain Android, you find thriving communities that provide a lot of additional content and usage options.Homebrew is great for everyone.Especially the GO and Quest models are basically nothing more than a stripped down Android phone with a split screen.Means Android or Android TV apps that can cope without any Google services and frameworks will work just fine.FB does not like this much so and makes it very hard to utilise what you might simply call emulators.Unless the Android(TV) app supports the gesture and controller setup Oculus provides many things just won't work as you need them, for example pinching to zoom in and out or tapping on the screen if the app expect a real touchscreen.An emulator would basically convert what is available in gesture and controller actions into what a "normal" app or game would expect.Some game controllers are supported but would it be great to move around for real while exploring your 3D game and to use your own hand to perform actions istead of holding an additional game controller?Oculus does not support "Thrid Party or homebrew", depending on how you read their agreements you accepted, it means your account might be banned, rendering your expensive device useless for any offcial stuff.There are unofficial, or if you like homebrew stores available.A place where you find early stages of new titles to try out, some free content and also experimental stuff.At your own risk and frustration though ;)A great project that never made it due to the complications with Oculus/FB was a robotics VR app.The goal was to control a robot or even mobile one, like a rover, through the headset and controllers/hands.The project ended when it was clear FB would not provide the required API stuff unless the app is devleoped under Oculus terms and conditions.Needless to say it quickly continued on a higher level for military use and remote bomb disposal.Some othe, private company saw the actual potetial in homebrew and snatched the developer off.Can't blame the guy considering the money...The main concern for any serious "hacker" providing real homebrew solutions are the offcial terms and conditions.Google for example still works o your Android phone if you install some custom firmware.You can even keep using the Samsung store and Apps if you did install homebrew on such a phone.Not to mention that you also install basically any other unofficial store you like on top.What you ultimately do with your device is up to you and might only affect your warranty based on claims that not always make sense.Oculus however reserves the right to terminate all access to their online features.This can include but might not be limited to:Updates, online store access, online features provided by Oculus and online features provided by apps and games from the official store.The concern here is that it basically means not a single Oculus app keeps working as they all call home once online.Games requiring Oculus services, like purchasing the next part of the experience fail then as well.And if played hard it means your linked account means even you favourite video player will fail to work.So far Oculus only made it hard and then even harder to give homebrew or alternative uses a chance.Not too many developers want to be responsible if their testers or users get banned and their devices rendered basically useless.What about predators?Vr is still a new thing in most parts of the world, some are already hooked in great numbers though.Especially in Asia Vr seems to be the new future already.Hackers showed in the past how easy it is to enter a room on a Oculus device and stay invisible, listen to conversations and even access the camera feed and take control of linked computers.Good hackers though who did this for the right reasons and results - those backdoors were closed.But it shows nothing is perfect, especially if age and content control is left to the user alone.VR works best with friends and if you don't have any (with a headset) you quickly find them with your heaset active.Many titles are "kid friendly" so to say and still offer chat options and virtual contact.No kid can buy these toys, so the responsibilty is entirely placed on the adults providing the technology to the kid(s) - usually the parent or unsuspecting family member thinking a VR headset is great xmas present for the teen..."Groomers" not only know what to say and when, they also know quickly if the watch a kid play and once they had a few minutes of chat they get ready.I have small kids in the family and with lockdown we are often reduced to doing things online instead.If you enter one of these virtual worlds and appear and act like a kid you soon find "new friends" especially if you pretend to by shy and prefer to be left alone.In the real world you won't find any kids bothering to become your friend if you act like this.The virtual world however seems to have an endless supply of kids like you and desperate to find a friend thinking and suffering the same....We all know how many of these kids are real on normal social media platforms and how reluctant they are to let the parents check on each other to allow these "play dates"....You might be able to monitor and moderate a written chat platform, no so much though if everyone is talking for real....A growing concer here is the nice option these VR chatplatforms offer to create "private" rooms.Be it for just chats and playing with wirtual Lego or to share a nice movie, there is an option for everyone.Parents usually don't bother to set up a screen for monitoring of what happens on their kids VR system, maybe they should...They don't see what the kid does and since it can get annoying, headphones are prefered, close the door and no one hears what the kids talks, if anyone cares.There are already pages on the dark web with all the required instructions to set up "a most pleasurable" VR experience - you just read them down so even a 6 year old can install and set up what is required - again use the few parental guidance options available on these headsets.So far the real risk is limited by the simple fact that not every sexual predator uses VR and that not too many kids (yet) have access to headsets.Does not mean there isn't planty of options to use their phone and some "CARDBOARD" to get going without a headset.There does not seem any concern to protect underaged kids in the virtual world - let their parents do it...Keep that in mind when handing over a VR headset for kids to use unsupervised for long periods of time...
