some help with android please...?

Just got myself an 8" Archos arnova 8 tablet with Android 2.1. Purpose is mainly reading PDFs, Office documents, viewing pictures, listening to MP3s en doing some light internet, all for travel.  The user manual was very brief. I need some simple apps: PDF and office reader. Nowhere is says how to install. Some sites like appslib and android market want me to have a paypal account, even though I will only need a few free apps. I might use my 8Gb micro SD card to get it via my computer, but really have no idea what I'm doing. Someone knows a nice tutorial for people totally stuck in the Windows/desktop age?

How to control a motor via app/microcontroller??

New to Instructables and I love the site. Not sure if I'm posting this in the right place or not! I'm completely new to the whole internet of things but intruiged by it and want to learn more. I'm looking for a bit of advice. I'm looking to make a basic enough app that allows the user to move a wooden dome roof maybe 6m in diameter. It's for a home observatory. Possibly move the roof according to degrees the user inputs also. Would I be right in saying the roof motor would have to be online in order to use through a smartphone? Would something like Raspberry Pi or Arduino be suitable for this? Sorry I'm bit of a novice but want to learn

Instructables App "network error"

I tried to use the Instructables app to write an instructable. I loved it, writing an instructable as you go and clicking the camera button was great, made it really easy. BUT when I got done and went to publish it I clicked publish and it said it was uploading photos.  I laid my phone down, Moto G running kitkat 4.4.2 on the counter, when I came back it said network error unable to upload.  So I clicked done and tried to upload again, this time it immediately said network error couldn't upload.  So I completely closed the app tried again, same.  Restarted Phone, same. All the while having a strong WIFI signal.   So as last resort, I cleared app cache, well, this deleted my instructable........ Those should really be stored in a separate file that is not erased by a cache clear. So what was wrong? I had a great internet signal, there was NO network problems. Webpages and instructables in the app loaded fast.

To ensure that Blackberry App World is correctly downloaded to your Blackberry, this site is not designed to work wih any other Internet Browsers. If you cannot use Internet Explorer, you may be able to download the software directly to your Blackberry smartphone". And theres no download link or anything there to help me out.

Instructables for iPhone

Don't you hate it, when you've finished building something outside and you've forgotten your camera? Can't wait to publish an instructable when you're out and about, and have no access to a computer? Both of these have happened to me, and I had a good idea. I propose an iPhone app for instructables. This app would be better than browsing on your internet browser on the iPhone because it would be made for the iPhone screen rather than for a 16:9 monitor. I think that it should have at least the following features:  * Offline Instructable Editor  * Instructable uploader  * Online instructable browser  * User page, in which you can check comments and edit your profile etc.  * Onboard instructable saver - instead of having to go online and browse the site to find the instructable again, the app could have, for example, 2MB of allocated memory in which to save one or more simple pdf files or similar of instructables, which may be viewed at any time, even when the internet connection is faulty. I truly believe that this has potential, and I just hope that the admins see this. I don't have the means, funds or time to make this app but hopefully somebody does.  Feel free to post any more ideas, as this would be a community app and I'd like it to be suitable for as many people as possible.

Dropbox application in background process on OpenWRT processor of my Arduino Yun.

Hello everybody, Simple question: does the Arduino YUN support the same DROPBOX functionalities as my laptop? Basically, I need to download data from the SD card of my Arduino Yun to my application server. But the internet connection of my Arduino is not very stable. How I want it to work: 1.    I have a sketch that writes data on a TXT file to my SD card every 10 minutes 2.    I want to install Dropbox on my Arduino Yun 3.    Then, whenever the Yun is connected, it will synchronize all the files from the SD Card with my Dropbox folder on my server. That would happen (I guess) in the background, without my Arduino needing to run a sketch. To do that, I think I need drobox to run ‘in the background’ on my Arduino microprocessor. Did anyone do this before? Thanks. What does NOT work: Initially, I used the "LogToDropbox" sketch inserted in the "Datalogging to Dropbox with Arduino Yun" tutorial at the following link: https://www.instructables.com/id/Datalogging-to-Dropbox-with-Arduino-Yun/ in order to ‘actively’ upload files to my Dropbox app console from my SD card with an internet connection. But if , my Arduino Yun is losing the internet connection, it is impossible to upload the files created during the downtime to my Dropbox app console. These files are stored on the SD card plugged on the Yun during this time interval, but not synchronized.

Creating a Local Network One transmitter, Multiple Receiver Application (Local Network Radio App)

Alright, So here goes(Hope this is the correct category): THE STORY I attend a Hungarian conference event held every year along with some of my relatives, family, and bunch of other people i know. The issue is, is that some of the Hungarians who attend this conference do not know the language very well, and require a translator. Our "group" per se, does not yet have wireless transmitter/receiver setup yet, and are looking for a solution for being able to broadcast the English translation to all who need it, without disturbing the actual event. So i began to think. While i was listening to a digital radio station on my mobile device, i asked myself, "What does everybody already have?" Then i realized: A mobile device. I then began to think, "Could i harness the power of these peoples devices, and use them as receivers?" Then the idea grew, and now i am left with this: THE IDEA My idea is to create an application which gives the ability for someone with a mobile device to broadcast audio to other mobile devices with the app also installed that are connected to either the local network (Preferred) or to the internet in general. What i was thinking, is to have the broadcasting device work as a wireless hotspot that doesn't necessarily provide internet, but instead streams the live audio to any other device connected to the broadcasted network, with the app installed. This way, anyone who needs a translation of whatever is being spoken can simply plug in a set of earbuds (And if someone doesn't have a mobile device, use an audio splitter) into their mobile device, and listen to the translator, who is using the mic on his mobile device to speak the translated version of whatever is being spoken. With this, nothing but software and mobile devices (Which everyone already carries around) Is needed. (The conference is held in a different location every year in order to make it suitable for everyone distance-wise.) Think of it as a local network digital radio app. The Translator is the radio station, and the people who need translation are the listeners/radios. THE PROBLEM The problem is, I know near to nothing about creating mobile apps for Android or Apple (Yet.). I know loads about Android, i work with it more than i do with Windows/Linux/Mac/Chrome. I have flashed roms, read into the OS, and done a few other things, but know nothing about building my own APK. Same goes with Apple, except i almost never worked with the OS entirely. THE SOLUTION/ANSWER What i would need, is help from people who have built apps, who know what they are doing, and have done similar things of such category. My free time is limited, and so i can't always be working on it. Nor is this project mandatory, i would simply like it to work efficiently by next year. I would be willing, and would love to learn how to build and design apps, so long as someone is willing to answer my questions. I don't plan on profiting off of this, so don't expect payment. (Maybe a donations page if this all works out, and other people start using the app?)  The idea is still just an idea, however i would love to go through with it and actually have an app of such created. Any constructive criticism is appreciated, and if i happened to do something wrong, please notify so i can correct it. If you have any questions, or are willing to help, please do reply!

Disappearing Intro?!

I am working on my first instructable, and I am having major problems. I downloaded the Instructables app on an iphone, so that I could take pics on there, and I am doing the rest on a mac. I already had done the intro and was half done with the next step. I was taking photos on the phone, and then saved what I had done on the phone to Instructables.com. When I logged in on the computer, all the pics and text for the intro was gone, and the first step had been marked the intro. In preview mode, the first step's title became the ible's name. After I recreated the text from memory, I worked some more and almost had the first step done, and then in almost the same way, it happened again. This time, I could not upload the pictures to the internet, because every time I clicked on the "save to instructibles.com" button, It would say "preparing upload", for a couple seconds, then the screen would go black for a split second, and return to the home/apps screen. I checked on it on the computer a couple minutes later, and it was not saved to the most recent pictures I had just tried to save, but other than that, it was ok. Now, about 5 hrs. Later, I Log on and the 1st step has become the intro, and the intro is gone. Luckly, all that text is still on the phone, so I can read-and-type it back to what it was. The intro pictures are saved onto my mac's desktop, so I haven't lost those, but I will have to recount the pieces on this K'nex instructable. Please help, either tell me what not to do, or maybe I have discovered a bug, but I hope this does not happen again. Also, this is most likely a bug: Whenever I am taking pics on the instructables app and I take more than two, once in a while it will flick to the home/app screen and I have to reopen the app. When I do, those pictures will not be saved on the phone, app, or camera roll.

(i know the led      placement in each corresponds with the type of led tv it is.) ____________________________________________________________________________ right now, i have a 19 inch CRT 4:3 aspect ratio (i am guessing 480p res) the TV itself is a "CurtisMathes-Tronics" brand (i never heard of it) (model # "CM 19022S"). its OK. it works, but its getting too small for me, and after i bumped into some money last summer ($700) at the peek and i am thinking saving for a "state of the art" HDTV! next year, with my summer job, i should have $1500 to spend.

Miscounting View Counter

Recently, I have noticed the amount of "views" shown when I look at my instrucables is inconsistent. Let me provide some back-story... At my house, I use an HP desktop running Windows Vista. On this my family runs Internet Explorer 9. My Mother has a Samsung Galaxy Tab 10.1 and she uses the most recent version of the Instructable's mobile app. I have a Samsung Galaxy Media Player 5.0 which also runs the Instructable's app. For those of you familiar with the new and updated app, you know that before selecting any instuctable you are able to see the number of "views" and "favorites" that item has attained. A few days ago I published another instructable. Being very excited to see how the community would react, I was checking the "views" frequently and noticed the numbers seemed odd. After further exploring the topic, I found that my personal device would show one number while my home computer ad my Mom's tablet also showed different. What I mean by this is the number of "views" before I selected my instructable on my device was different from when I clicked on it on the same device. It was also different for the tablet and the computer. I understand that as time goes on my "views" will increase, but these changes were ranging from 2,000 "views" to 4,000 "views". I don't know if this is a side-effect to me since I am the author of these instructables or if this would happen when I view other people's. I also don't know if this affects other attributes (i.e. Favorites, Comments, etc...) or if this happens exclusively with "views". I will keep my eyes open for relevant information and keep anyone interested posted for changes. I know this is not a major issue but it is indeed an inconvenience. If anyone else is experiencing the same problem please leave a comment so I know I'm not the only one. Also, to the people who take care of these bugs, please let me know if there is any more information that you need to help you out.   -mymyjames2000

Simple (I hope) Treadmill Incline indicator

Hi,  I have an older treadmill that has a button to control the incline, but doesn't display the incline. I have a treadmill program app on my iPhone that guides me through a exercise session by telling me to set the speed and incline many times throughout the 30 minutes I am on the treadmill.  I would like to build something to display the incline as I adjust it.  I have just enough memory from all my childhood Radio Shack projects learning to not be afraid to attempt this and also the vast knowledge of the internet :) I have already calculated and marked the incline differences on the frame of the treadmill near my feet but I can't really see it well. I figure a small LED display would work best. I can visualize running wires up and down the frame to the LED display to an arm that will move with the treadmill while hitting contacts. I am sure I can get this to work but it sure seems like a lot of wires so I feel I am missing something. If anyone has any suggestions about an easy way to do this or can draw me a diagram of what I would need, I would be forever grateful. Thanks, Cindy in Indy

Banner/rollover ads with uncontrolled sound and auto start

Why are you allowing ads with sound? Perhaps you should have your ad agency go here http://www.langoor.com/ethics-in-internet-selling-and-advertising/ and learn some ethics. There are ad placement firms who adhere to guidelines that help to maximize a user's experience rather than irritating the crap out of them. They seem to be doing pretty well.  Reducing a user's experience may generate you and you ad service some short term revenue, but it will ultimately reduce the user's willingness to buy the product of the offending advertiser, and will drive eyeballs off of your site.  I clicked on the "First Aid Kit for Hostile Environments" 'ible in my Mail app. My browser opened, as usual, and opened my instructable page. Then the music started. Thinking that I might have lingered over something too long, I closed the tab, went back to the mail, and clicked again. Same story. This happened three different times. ALL of the ads in the top banner did this. Idunno what the first one was, but the second one was for some Republican politician, and the third was for Mercury (the car, not the element).  I have not resorted to ad-blocking software because I believe in your site and want you guys to get paid for all your hard work. (That may soon change, though.) I haven't bought a pro membership because I don't publish anything or spend gobs of time here, and I've been a member so long that you gandfathered in most of the pro benefits for me. I'm relatively casual and limited in my use. Can you help a brother out and stop these types of ads, or are you gonna tell me to just suck it up because I'm a freeloader non-pro member?

Help with adding LED's and mini fan to existing circuit.

Hello, and thank you in advanced for taking the time to read through this and give me feed back. I greatly appreciate it. So I have a working circuit that is running off a 3 prong 120 V AC 10 amp power supply. I thought i would pretty it up by adding a led lit power switch and another plane led in a different spot, and make it a bit more reliable by adding a fan on the inside of the enclosure. I downloaded and app that calculated how much Resistance I need from the power supply to each led and fan (all in parallel). After i hooked everything up to what i thought would be an easy mod. to my surprise I smoked the resistors in under 60 seconds.   I talked to a friend who gave me some basic direction but couldn't give me technical stats. He said i needed to start with a transformer (i believe is the term he used) to drop the voltage, then to go to a bridge rectifier to turn the AC current into DC, then after that i would need a current regulating switch to give the proper supply for the LED's and Fan. Then from there he said i would be able to calculate the Resistance needed for each Led and fan and would be able to hook up the resistors needed with out damaging them. If this is the correct steps to take I can understand that; however, he was not able to give me any technical info on any of these components and what i would require. If these steps are correct, what i need help with is to determine what specs i would need for each piece, Including the resistors after the current regulating switch. (Technical Info) The 1st LED im using is a Switch that lights up when on and has leads just for the LED (the switch is already being used and works). I could only find the style i wanted from an automotive shop so it says for the led 12V only(unfortunately i couldn't find specs on the amperage the LED takes, but the switch itself is rated at 5amps). The second Led is a basic Green Led that i Purchased from radio shack, It is 2.1 V and runs on 30 MA, The fan im using is from an old game console and is 5V and runs on 80MA. Thank you for any and all help you give, this went from what i thought was an easy stylish mod to me ripping my hair out and scouring the internet for info, i finally gave up and decided to join this great community to ask for help with my specif conditions. Thanks Instructable Fam.!

I have made a previous cardboard robot as a proof of concept for my next build and used an iPhone chatbot app which worked quite well, but I would like to make my own stand alone chatbot.    I am aware of the likes of "Pandorabot" and "Cleverbot" ect, but what I would love to do is program my own stand alone chatbot using the available hard drive memory on an old laptop I have laying around collecting dust, and use the Windows xp voice recognition to talk to it (speech to text) and have it respond with a spoken voice (text to speech) which would come out of a Bluetooth speaker located in the robot. I know my way around a computer to some degree but do not know how to program (although I did follow a program written down once to make an  analogue clock many moons ago), but with some hopefully straight forward instructions I am willing to learn and give it a go. I have a rough understanding what AIML is but don't know what I would need to use it. I want to go down this road as I want to have it off line, i.e not have to rely on an internet connection, except maybe my home network to connect to another device, not to rely on a second party server, and would like to put the old laptop to some use.  I know I bit about teaching or training a bot to respond, i.e, giving multiple phrases or questions with one meaning (eg Hello, Hi, What's up, Hi there ect,) and the bot to recognise and respond accordingly, and I'm aware it will be time consuming, but it's the basics, or starting blocks that I'm after, getting a bot up and running and ready to be taught or trained, and if it's something I can get my head around and it's something I could realistically do, I would love to give it a crack.  So, Is it reasonably possible for me to use my old laptop for the sole purpose to use it as a chatbot, what would I need to set this up, Can what I need to know, be broken down in to easy to follow steps for me or anyone to follow who does not have experience in this field, And what recourses are there that I could use if needed? Any help, thoughts and suggestions that anyone can offer to get me started on this idea really would be greatly appreciated, and may be of help to others too as I have not seen this sort of question asked anywhere on the inter web in regards to just using a home computer / laptop. The only information I can seem to find relates to online bots. So thank you in advance for any help offered and I look forward to any responses. Steve.

Arduino D1 temperature code is not working for me.

Hi,  I'm working on a temperature( DS18B20) project with the model D1 of Arduino and I will like to connected to the internet via Blynk . I was able to configure the WiFi and the blink project. But when I try to use this code the application of Blynk say that I don't have connection with the board. I find a code that everybody is using but is not working for me. Can you help me please?   This is my code: #define BLYNK_PRINT Serial // Enables Serial Monitor #include #include #include //EAO #include // OneWire DS18S20, DS18B20, DS1822 Temperature Example // // http://www.pjrc.com/teensy/td_libs_OneWire.html // // The DallasTemperature library can do all this work for you! // http://milesburton.com/Dallas_Temperature_Control_Library OneWire  ds(7);  // on pin 7 (a 4.7K resistor is necessary) WidgetLCD lcd(V1); // You should get Auth Token in the Blynk App. // Go to the Project Settings (nut icon). char auth[] = "f7d376f1ae554207a6666c45babe7e69"; // Your WiFi credentials. // Set password to "" for open networks. char ssid[] = "Samsung Galaxy Note 4 0628"; char pass[] = "1234567"; void setup() {   Serial.begin(9600); // See the connection status in Serial Monitor Blynk.begin(auth, ssid, pass);  // Here your Arduino connects to the Blynk Cloud. } void loop() {   Blynk.run(); // All the Blynk Magic happens here...   // You can inject your own code or combine it with other sketches.   // Check other examples on how to communicate with Blynk.

The future of mobile operating system or the end for "hackers" and rooting?

For mayn years it was almost logical to get full root access on your new smartphone or tablet.The other fraction might now it as "jailbreaking"...No one really needs it unless they are not happy with they way the mnufacturer designed the operating system and features.The removal of bloat, apps the user never needs, is still the most common reason for rooting.Custom ROM's offering a different experience are right behind.Now we also have TV's, entertainment boxes of all kinds, even from our ISP's directly.The main provider for the operating system is now Google with only a few "competitors" left.Apple has a strong hold of the mobile and tablet sector too but is not really presented in other areas.Android is still open source but Google heavily modifed it to suit the needs of data collecting and security for features like banking, access control and so on.What is good for the normal user and perfect for those with security in mind can be really bad for those actually just using a device.No matter why you buy a new phone from your provider, you almost never buy it for the added apps and services.Rooting has become more and more difficult.One reason of course is constant security updates and removing possible access options for even simple things like getting USB debugging and an unlocked bootloader.People dedicated to find ways to remove provider locks, creating custom firmwares or the basic tools required to work with firmwares were called hackers.If you buy a new car and decide to modify it with a new engine, seats or whatever than no one will stop you.So why don't we have the same rights for our electronic companions?I wouldn't call it hacking, I would call it actually owning and controlling your device instead of Google letting control you - or Apple, but who cares....The other reason is dead simple: Those guys who started it all have retired or found employoment with those they fooled for so many years.Chainfire should ring a bell for anyone ever concerned with rooting.The master is gone now and only a few people are willing to take his legacy.For Asian devices the community over there is better off but for our market region right now Magisk seems to be the only option left for modern devices.The sneaky ways to lock us out....Security comes at a price, simple as.You can offer secrity for money transfers if the device is not trustworthy.Same for online streaming - you want the money for what you give and prevent that someone is able to make unwanted recordings without encryption.The list goes on with access control system and literally everything we use our devices for that involves some security.Even with the lates PIE systems Google's own devices are still quite friendly in terms of gaining root access.Different story though if a manufacturer makes full use of all the latest addition at Google's disposal.Device security no longer starts with the boot we see.It is now possible to create a hardware based tree of trust.This means any modification to anything will cause a failure.This locks out all "tools" able to read out partitions and vital data while a device is in fastboot mode.And of course said fastboot can be fully disabled as well now.For security reason a so called A/B configuration is used.Updates come over the air and are applied to the dormant system.Next start will boot the new system and then update the old one, no requirement to manually apply and update.The recovery can also be abandoned and replaced by a system using a copy on the device itself that is updated through OTA updates with the firmware.So both ways to gain official access can be full removed from the user.From there we get encryption, hash checks and literally everything working in its own user space - a full SELinux enviroment at the highest level.There are already devices utilising a lot of this and so far the only way to get any sort of insight was done by those intercepting OTA updates on a router level.And apart from quickly changing the encryption with the next updates nothing was gained.Is it all coincidence?Of course not.Well known leaks were kept open for years.Kernel updates gave improvements and closed really old leaks but never all known ways.With the retirement of the best rooting experts these holes were suddenly closed.Checks of latest kernel releases showed that there is no known vulenerabilities anymore that can be misused to gain access.And those finding new ones and making them available for us are bascally gone now.Encryptions and packing algorithms changed, same thing for the actual handling of partitions and rights.Anyone with a decent understanding of how the old ways worked will be able to figure it out with some time wasted on it.From there however the outcome is often dark.The tools needed to work with these new files are not always updated anymore.The developer simply moved on and most of the time without publishing his source codes.And the still best way to protect your firmware from tampering is to encrypt it.In the old days it was enough to sign a ZIP file with a release key not available to the public.Custom recoveries allowed us to get around this.This still works to some extent but now we also get additional checks starting from the bootloader.A modified system will be detected and stopped and a stock system will stop i a modified boot is detected.Even using a custom recovery by flashing or through fastboot is preventable now.Right now the only way for most new devices is a total wipe and the installation of an unsecure firmware with everything.As you already guessed this is to prevent now as well.So does all this rooting stuff actually concern you?Of course not!If you never had any need for rooting or no clue what to do differently with a rooted device than you are a happy camper.But your neighbour or friend might think differently.You see, I have two problems when it comes to "stock" devices.a) I have no clue what data they collect from me and what it might be used for.b) I do not like being forced to agree to terms that are endless and of questionable content just to use the damn thing.For crying out loud: In most cases it is now impossible to even set up a new device without working internet and a Google account.....

Arduino heating controller: solar panel, oil burner, stove. NEED HELP AND ADVICE

HI this is my first time with arduino and electronics so please be forgiving.i want to make a controller for my home heating system and if it possible be able to control (change temp. setting, see statistic, etc. by phone - Bluetooth).so, i have three source of heat: solar panels (water), oil burner, wet stove. first part of plan is to connect all electrical components correctly (to make sure nothing blowup), second step is the program. third connect controller with phone by android or have a option to send sms to turn on/off oil burner.let's startthe heating system should looks like that (photo attach)please don't focus on the plumbing (that's only sketch), electronic and programing is more important.program (second step) should do:1. if T5 >T2 pomp P2 work 2. if T3>55'C , P3 work but only if O1 is switch off (automatically P1 and M1 is off, because they will be connect directly to O1 power) 3. option to on/off O1 by click on the phone (or by modul GSM in the future e.g sim800L) 4. additionally options 2 and 3 they are conditioned by other sub-option of 5 zones (where hot waterwill flow, so what will be heat): a)olny hot water in the tank- M3 open, b)only underfoor h.- M2 open, c)only radiators- M4 open, d) all heating, no tank- M2 i M3 open, e) all M2 M3 M4 open. so, before turn on O1 start making fire T3, one of the zone have to be pre-sellect.also if T1 >60st.C (and O1 and P3 are off), P4 will turn on (dump extra hot water to underfloor h.).that's all, nothing more .... but it's to much complicate for me right now. :smiley-confuse: and third part: all should be controll by simple phone app (android) e.g. turn on/off oil burner (maybe timer), change temp. in tank, change zone, see statistics etc.thera are elements what i have already- arduino nano-logging data module-relay 8 ports-bluetooth modul At-09, ble-4.0-extension board nano v3.0- temp. sensors DS18B20 i connect everything by all info what i've found in internet. also i tried to do simulation in THINKERCAD but many of my elements are not exist in the program, stiil no win. i didnt want to connect power just in case of blow off :o this is what i already found online:http://www.reuk.co.uk/wordpress/arduino-solar-water-heating-pump-controller-design-and-code/https://thesolaruniverse.wordpress.com/2016/11/21/monitoring-temperatures-in-floor-heating-loops-with-an-arduino-with-data-display-on-a-3-5-tft-screen/http://house4u.com.ua/articles/solar-controller/en/part11.phphttps://www.instructables.com/id/2nd-Gen-Arduino-Hot-Water-Solar-Collector-Controll/https://forum.arduino.cc/index.php?topic=70048.0and about bluetoothhttps://arduino.stackexchange.com/questions/19517/hc-05-bluetooth-module-inq-command-doesnt-worki only showing the links to proof my hour's spend in google.i think first two are the best.so i put together all what i found and this is my first program:const int TANKSENSORT1 = A0;

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. It's relevant to what I have to say...here it is: ********************************************************************************** Overview Specs Features Includes Warranty Supplies IBM ThinkPad T42 2373 Specifications Part # 23738TU Key Specifications IBM ThinkPAD T42 2373 Manufacturer IBM Manufacturer Part # 23738TU Processor Type Intel Pentium M 735 1.7 GHz Data Bus Speed 400 MHz Cache Memory Type L2 cache Installed Size 2 MB RAM Installed Size 256 MB Technology DDR SDRAM Memory Speed 333 MHz System Type Notebook Storage Hard Drive 40 GB, 5400 rpm Storage Controller Type IDE Optical Storage Type DVD ROM Read Speed 24x (CD) / 8x (DVD) Display Type 14.1" TFT active matrix Graphics Processor / Vendor ATI MOBILITY RADEON 7500 Video Memory 32 MB Max.

IBM 23738TU Summary ********************************************************************************* NOTE...I DON'T BELIEVE THIS...I JUST TYPED FORTY MINUTES REPLY HERE and it instantly scrolled up like speed of lightning and disappeared like last night. 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.
