There appear to be some fresh updates. From what I see: New photo layouts, which seem to make better use the screen space on desktop. Nice! Up-voting on comments! The old forum Questions now appear to be an aggregated list from questions asked on actual Instructable pages. That's an interesting tweak.High five to the Instructables team. Nice to see, keep up the good work!What else are people seeing that maybe I haven't noticed?

My "Discussions" tab showed no changes for about two months, and then yesterday it dumped about two months of replies that people had made on my various comments I made on the forums here. I think that qualifies as a bug. I mean, ideally my "Discussions" tab would notifiy me of replies in a matter of hours, so I could reply to those replies in a timely fashion, if it was the sort of thing where someone was expecting a reply from me.I am guessing this problem was maybe related to the recent big "improvements" to the site, to make it more readable for mobile lusers, and other changes to make the site more comment-able, question-able, tip-able, by everyone.Just wondering: Has anyone else experienced this same problem, i.e. a several weeks, or months, delay in notifications of replies to your comments?

As "A last Hurray" so to say I will do it one last time....What am I doing exactly you wonder and why do I bother writing it here?I will write a little story that is spiked with some information that I deem to be worthy to share.And I do bother to show my friends, followers and those who care what might have been a weekly or even daily thing otherwise :)At work recent changes and ongoing problems with our IT systems required that those who need contact with those in charge or above to sign up with Facebook.I tried what I could but Emails appearently don't always show if someone actually ready them and it was down to keeping my job or refusing Facebook.And yes, I tried to raise my concerns about privacy and control of it through the company...Anyway, let us start, shall we?Signing up for Facebook is as easy as asking Google for the name and to follow the obvious links.But those who know me can confirm that I take privacy seriously and that I like to question why someone thinks they need certain information.Which brings me to the point....Anyone these days is on Facebook with one or more accounts - this includes your boss, manager or anyone interested in your name, resume or other background info.Facebook provides just that, the chat and messages are as obsolete as anything else in terms of actually giving you privacy of any kind.When I signed up and was dumb enough to use a well known Email provider for my account details, I was shocked by the following offer.I was asked for my Email password to make signing in and finding friends easier!A quick but endlessly long search through the terms and conditions confirmed that indeed everyone in my contact list would be mis-used for data collecting and referencing - including the content of my Emails.Of course I had to reject this great function several times until Facebook got the massage that I like to keep control over my Email account.Thinking this was already enough for the day I rejected images and other private info, like where I was born, where I worked and such before signing off.Next day I suddenly had a list of friends as long as the shopping list of a childcare centre for thanks giving.At first I though I don't know any of them until I started to do what Facebook wants and looked the people up.Most where contacts I had on long dead messengers like the Yahoo! messenger.You can understand my confusion until I realised I had used the same Emal account for those messengers.Facebook simply reference their records of dead systems with my Email address and was happy to provide friends I really tried to avoid....The hardest hit however was when I realised that even contact backups I did from my mobile, using Google services, appeared.Thankfully most as possible friends but some directly added to my friends list, due to other links they found in their databases.Needless to say that even several of my skype contacts showed up...The last thing that confirmed why I avoided Facebook was the simple fact that all privacy options in the profile are set by default to public!Of course, if you don't mind stripping down your privacy to the entire world while Facebook is using the data for not always legal purposes you shall be fine.But if you only care a little then check the following, hopefully before stripping down:1. Never, ever type your Email password into anything coming from Facebook - no matter what reasons they claim!2. Before you complete your profile with address, phone number or similar, type in nonsense so you can get access to your account settings.After all Facebook does not bother to offer you privacy before you finnish your details and keeps nagging about adding more so they get the vital data they need first....3. Check all account settings in regards who has access!Unless you really want to strip down noone but your friends should have any access to anything.And even for that you should make sure to enable the function to review them before you allow them to show up on your page, history or elsewhere.Things to always keep in mind:1. Your account is not yours as Facebook has all rights to it, you can not even request to have your informations deleted from their databases or remove your account for good.2. Anything your friends see on your page or profile they can share, like or comment on.This means that even if don't like it, it can spread through the community within seconds and as a worst case ruin your life.3. Anything Facebook does or offers, like games, recommendations, things you should know about, have only one goal: To gather more information about you.Like for example using your Google cookies to find out what search for on the web or watch on Youtube....4. Things you like attract more things you might like, again mostly to gather more info about you, your personality, preferences and your friends.Ok, I know!You are using FB for years, have tons of friends there and keep updated about every minute of their life they share...So there is little to no chance to see what I am talking about LOLBut I would not post all this openly without a backup plan ;)If you really dare to challenge me on this then you might have to waste several hours of your precious time, but I think it is worth your time!This is how the game is played:1. Find someone older who does have a vital Email life of sorts but so far no use for Facebook.2. Ask kindly for his support on a test with Facebook that might require him to forawrd correspnding Emails to your account.3. Clearly state that neither his email or FB account will be used to post anything, add friends manually or give out any info the person does not feel confortable to share.4. Point out the possible benefits of having FB with the option to use the persons real name so he can continue using FB after the test if considered a good thing to have.5. If you manage the above successfully then only use the provided name, email and residential address to create a new account.6. Observe and wonder about the things to come.....You will notice that usually quite soon possible friends or persons that could be connected show up.Also that FB will continue to ask about the history, like schools, work, places.If you do an online search on the name often takes less than a week to get a hit refering to FB.The more info about the person you offer FB (with consent!!) the more people will show up to be considered.At this stage and I guess in less than two weeks time after creating the account comes the question about how to continue.Show the person what and who is already present in the created account and if there is an interest to keep the acount for personal use.If so, kindly ask the person to add a friend or more, fill out more details, provide a picture and so on.Hand over full control to the account either by asking the person to change the password and not let you see or know it.Again, ask kindly to get some future updates, screenshot or similar to see how the account evolve, or add yourself as a friend and keep track that way.I do not suggest in any way to create an account without consent!This includes all activities that might seem harmless:Don't use the identity of someone you "found somewhere"!Don't create a fake account, especially not in the name of someone popular or someone that might be harmed in any way by your creation - the person might have good reasons not to appear on FB!If you don't have Facebook already feel free to use to do the test with your own details!Never, ever use pictures that are not your own or that you don't have the explicit permission to use even if you took them!

So I recently thought up the idea that I can get free high speed internet at the computers at the public library in town (I can only get dial-up at my house). I have to ride my bike a few kilometers to get into town but I can get like 100 KB/s!! Gah, I wish I'd thought of this a long time ago. When I went in yesterday I just downloaded a bunch of crap. I got 60 MB of stuff, mostly podcasts, in about ten minutes. That would've taken me over five hours to get on my dial-up. But is there any thing else that I should try, other than just downloading a buttload of stuff? I've never had broadband, so I'm kinda just dumbfounded by the possibilities.

Hi, First time poster here, sorry if I'm misplacing this. I have near zero knowledge of engines, though I understand physics, at least from my civil engineering college years. I bought a variable height desk from IKEA (Skarsta model), which has a 12cm radius hand crank (see photos) that ends in a hexagon shape, h=6mm (so diameter around 6,93mm). This hand crank works fairly easily, needing little effort to crank the table up, with ~45kg of weight on it (it's supposed to go up to 50kg). So basically I was thinking if there was a easy, cheap and safe way of automating this with some sort of electric motor (I even looked up those Lego Technic motors!). Any suggestions? Thanks

There are a number of questions like I think the RV will have problem with a static IP or maybe not any ides on this would be grate?

3D printers have seen insane amounts of attention in the past year with lots of stories coming out about how amazing they are. How they can make replacement parts for anything that breaks. How they’ll revolutionize manufacturing. How everyone will have one and they’ll do everything that you need ever. Long story short, 3D printers are pretty amazing, but they aren’t quite the miracle on a stick that the hype is pushing them to be. So let’s sift through and see what there really is to get excited about right now. Consumer 3D printers AKA what most people will be using The 3D printing that’s available to consumers right now is fused deposition modeling or FDM. These printers build up a model layer by layer by extruding ABS or PLA into the build area. It’s basically a much fancier version of a glue gun. A tiny glue gun controlled by a computer, that is. These 3D printers typically run $1k - $2k, but smaller ones can be had for as little as $200. The MakerBot Replicator 2 is the most popular printer of this kind, but there are dozens of others to choose from as well. With some fiddling and work you can pretty much print any shape that fits inside the build volume. So if the printer can fit it, you can make it. That’s simplifying it a bit (OK, a lot), but that’s the idea, and it’s a very cool idea. After some practice you can learn how to design new things like jewelry, ornaments, or toys. Since everything is printed out you can customize any piece that you’d like. Take a couple hours to learn 123D Design and you’ll start to have new things to print out. That’s the power of 3D printing right there. You can quickly go from an idea to a design and then to reality. Your skills in making things by hand don’t matter here. This is why it’s so amazingly helpful to use a 3D printer for prototyping your ideas. I recently worked on a flash drive case and the first model took about 2 minutes to design. After that it was about 15 minutes to print out on a Replicator 2. Then I tested it and adjusted the design for another print. I repeated the process a few times and within 2 hours I had a file that I was happy with. This is even better considering that I only spent about 20 minutes of those 2 hours actively working. The rest was spent on other non-related work. All about the materials So that’s the power of 3D printing. With services like 3D Creation Systems you can upload your file and get it printed on much fancier machines with better resolution. There’s no immediate gratification, but you still get a high-quality print quickly and access to more materials. Even with this expanded selection of printing materials, it’s still a very limited selection. If we were just to look at all the plastics out there we’d be here for days. There are thousands of them and that’s just plastics. There’s also wood and metal and more beyond that. Each different material in this insanely huge selection has a different quality to it. I’ve seen countless people print out items in ABS or PLA and complain about how their printer must not be working since the printed piece doesn’t work like the original. But of course we can’t recreate every item out there with a couple kinds of plastic. It's about using 3D printing with other tools The key forward in using 3D printing is to use it as an amazing new tool of forming great pieces to work alongside all the other great items and materials out there. Why bother making a weak spring out of plastic when you can drop in a metal spring? So 3D printing isn’t everything, but it can be used alongside most everything. It can get us where we want to go so much faster than before it’s ridiculous. But it’s still not the miracle on a stick, not the only tool we’ll ever need from here on out. When the hype dies down we won’t be looking on at amazement at something being 3D printed, we’ll be looking at lots of awesome new things that were made faster with the help of 3D printing. And that is going to be incredible.

Greetings! I'd like to give everybody heads up about some big changes happening on Tuesday (1/23) at 9AM (PST). First off, the Instructables pages are getting a major update. Aside from a sparkly new look, they will now have a section for Questions and Tips. This will provide a place to ask questions when you get stuck, or provide a tip for doing a project better. Secondly, the Community pages (i.e. these forums) are getting a very long-needed makeover. Finally, we are updating our search software, which should improve search results on our site in general. These changes will require a period of downtime on the site of about half an hour. Please check @Instructables on Twitter for updates. Stay tuned for more great changes to come in 2018!

The SciStarter Citizen Science Contest is live! This is your opportunity to help millions of citizen scientists contribute to real scientific discovery. Make their experiences better by coming up with solutions to some real annoyances that hinder their participation. To get you started, here is a specific--and very real--challenge sent to us by project organizers. STOP CRITTERS FROM EATING SUNFLOWERS Background: The Great Sunflower Project uses data collected by citizen scientists to create an online map of bee populations. Participants grow sunflowers, observe how many bees visit those flowers, and then submit their observations. The Problem: Critters, like mice and birds, often eat the sunflower seedlings before the bees are able to visit. As a result, some volunteers are unable to collect and submit data. The Challenge: Create a safe, simple way to ensure the sunflowers are protected from critters and reach maturation. Enter now! Contest closes January 21, 2013

I would need the same type of transmitter like any bluetooth mouse would have inside. The mini pc I am building has both bluetooth and wireless display.Parts list so far15.4 samsung screen pulled from a Dell laptop modle LTN154W1-L01Control board for the screen with hdmi ebay 30$ link https://www.ebay.com/itm/HDMI-DVI-VGA-LCD-Lvds-Con.. 12v 3 amp power supply for the screen controler I already have but later I would build voltage control unit that would charge or power the whole unit. Again YouTube has videos and links for the part for this. And I really don't want to have a bunch a supplies to run it. While prototype it I will the final will run from the laptop I got the screen from. It should plenty of power for a single board computer like the new pi 3 to be added and the audio amp15.4 4 wire overlay conversion many sorce's about 50$ link https://www.ebay.com/itm/15-4inch-4-Wire-Film-to-F... $Ar1100 touch to usb mouse adafuit 10$ link https://www.adafruit.com/product/1580Hdmi wireless receiver. 20 to 40$ depending on features like if it has chromecasting and such I just need video so I think the 20$ unit will do nice. These can be found in many places, so I would think this to be open end item depending on features the builder wants. I would buy the best you can afford to leave it fexible .The last thing I need to make work would be usb transmitter to make the ar1100 bluetooth or matched pair of 2.4 dongles usb this is the only item missing. I could test the whole set up but would have run 1 usb cable, but that's a deal breaker for full wireless... If I had a old bluetooth mouse and knew how take its transmitter out, that work but a bluetooth usb adapter the would plug in the ar1100 board would be the thing I need.If someone would know how to remove the mouse transmitter and wire it to male usb plug I would be happy to buy it. I real want this to made from as much recycled parts as possible.I just don't want to have run a usb cable from ar1100 to the pc.I don't think the same usb dongle that's used to the pc is the same as the one used in every bluetooth mouse or keyboard. That's my idea for a wireless touchscreen handheld All the parts are easy to get I just need make the ar1100 usb board and wireless usb transmitter. The pc would use GA-h77n-wifi mini itx as it has both bluetooth & wireless display and wifi.Part 2The idea sound lol! I want to build a frame for the screen with speakers and laptop battery and used the power supply from the Dell laptop I got the screen from, that would need a small amp. Since the receiver is hdmi, I would think the audio would be there if not that would be simple to just use a bluetooth stereo headphones and run the earphone wires to the small audio amp.I would like any comments on this idea and a sorce the one part that missing the usb mouse transmitter for the ar1100 and this could be built.So What do you folks think? A portable monitor 100% wireless that could even double as touchscreen remote! I even thought down the road to add the new pi 3 to it as that would completely independent as low power tablet or connect to the pc that nvidia gpu and could stream pc games to My Nvidia shield too. With all the power of I7 2700k oc to 4.2ghz.The possibilities here are endless you and all kinds a features adding a mic and Webcam for video calls with sckype or google voice and messenger and bingo u have a voice and video over IPThis do able you think?All comments good or bad give to me straight.Oh but go easy on the grammar thing. I technology geek but a 56 year old high school drop out. But hay at 37 I was disabled with fractured spine by time I was 40 I did all computers repairs for my local high school and was building white box computers out of my home office. If there is 1 thing I have learned in this life anything is possible but you have to try!Please be positive and constructive with your questions and comments.

Hey y'all, I was bored, so I made this RC hovercraft, kinda like a Tiny Whoov, from the guts of a $5 RC helicopter (sold at most FiveBelows). The idea is that a hovercraft is more fun than a cruddy helicopter, in addition to being a fun and easy DIY project for the weekend. It could be a nice gift to a kid. My first concern was that the motors would not provide enough power to get the thing moving. They give more than enough power, and this thing can MOVE. My second concern is that the differential thrust steering system (one motor turns faster than the other, steering the hovercraft) would not be effective enough. This is still a problem that I don't have the enthusiasm or time to solve anymore. Maybe someone could figure out how to reprogram the FC board to have more differential thrust (is that possible?), or somehow configure a servo or actuator without raising the cost of materials too much. Anyway, here's the concept, go have fun with it.Supplies:Foam platesHot glue$5 RC helicopter with 2 motors and receiver (LED optional, but really cool)Connector (the battery might be soldered directly to the FC board, so this will make it easier to fiddle with)Soldering iron (not %100 necessary, but it can come in handy)Propellers (see design notes)Design notes:Notice how the underside of the hull is curved and smooth. I used propellers from a Blade Inductrix FPV Pro, but any micro quad propellers should work. Notice the nice little compartment under the FC board where you can stick a battery without the need for Velcro or glue. This would be a very easy FPV mod, but that would add about $20 to the cost.

Greetings everyone! It's the time of year when colorful twinkling lights adorning nearly every structure you can see. LED's have become more popular as of late, and from an energy standpoint that's good. I know most people can't see a 60Hz flicker but I can, and it's quite unpleasant to sit across from a tree full of LED's all doing the same on-off-on-off nonsense. I am fortunate to only get headaches though, other epileptics I've known have actually had AC LED's trigger seizures. So what can be done about this? We bought LED strings before thinking about flicker and have since replaced them with incandescent ones, but I've still got all the LED strings in the closet. I'd really like to be able to use them. Perhaps I could fashion a device that acted as a middleman between the outlet and the plug on the lights that would smooth the incoming current? I have two ideas for this: 1. Filter incoming current with an RC circuit 2. Rectify the mains voltage I'm curious if anyone else has attempted, solved, or even just noticed this frequency problem? I don't mind re-inventing the wheel, but I'd rather not build it square. Happy holidays! **yes, I just said happy holidays. Deal with it. :)

My name is NicholasI am in Year 12 at Parkes Christian School and making a major work that i can track where i am hitting a cricket ball on a bat. similar to what hot spot is and to be able to relay the information on the position to a phone via Bluetooth(video to help with what my idea is) At the moment i have ordered a Raspberry pi for the help transmit the data, EeonTex Pressure Sensing Fabric, EeonTex Conductive Fabric. But i dont know what else i would need so i can get the information of the position to a raspberry pi like what types of thread do i or is there some thing else i need as this is my first time making something like this Thanks in advanced

Just a quick word to say Thanks to everyone who contribute to this site.I work as a teacher in a max-sec prison and I have to produce a lot of my classes with a very limited acces to the web. Luckily, I can acces this page.Instructables has given me a lot ideas and explanations that I have been able to use in my work - and that is all down to the people taking their time to make pictures and produce text to explain stuff to the rest of us.Thanks for that!Ramsing

I have edited an existing instructable https://www.instructables.com/id/Arduino-Controlle...and have uploaded extra images to step 7. The first 3 images show OK and there is an icon labeled "8 more images"when I click on it the wait symbol appears and the images never load.This seems to be a problem on my Chrome browser.Other browsers show the images but won't display them in the slideshow. The only one that seems to work on all parts is MS Edge.If you go to step 5 which has existing images and click on the icon for 6 more images they all load.

I got a new project to make a pretty unconventional (fitness) game controller using Arduino to control Android games. The ideea is the following: using the Android VR technology (Cardboard or Dive) it was pretty simple to create a basic game (3d world to walk around) using Unity3D and Dive SDK. If you put on the Google Cardboard, the VR experience begins. But still so few devices are on the market, which give you back the control over your smartphone, which now is fixed in front of your eyes. I want to use this and make a fitness app which will be controlled by running on a treadmill (or using a workout bike). Something like the old Nintendo Wii and the running game from Sports. Or a game like Temple Run, in which running the treadmill faster, gets you faster in the game. For this I would like to create a game controller which records the leg movements, direction, body position, etc. which would then influence the actions in the game. A lot of details I still need to work out. So the question is, does anybody know of a guide or tutorial on how to create a game controller like this, using an Arduino a bluetooth module like HC-05. The controller should not be bound to a specific game or 3rd party app, should work like a usual game controller for android (connecting to some bluetooth android game profile?). There are many android game controllers out there which dont need a special android driver/3rd app to control any game. So this has to work somehow. So how can I programm an Arduino to send (once paired) the same events a bluetooth gamecontroller (or bt keyboard or mouse) sends, which doesn't need any 3'rd party Android app to be able to send basic key pressed events to a random game. Best regards, F

I cant seem to print off instrctables anymore saying that I'm not a premium member. I have not received an email saying that my subcription is due to be renewed. Is there an administration side of instructables that I can contact to discuss my subscription?Any help would be great. Grant

Hi, I own an Alcatroz Airwave 300 for 6 months and I have issues with battery. I always use it when I got home from school, doing homeworks, doing household chores, even going out to the public. I always charged it until its full but they only last for 2 1/2 hours. Recently, I noticed that my battery discharges easily. It doesn't last for 5 mins. So I decided to open the headphone where the battery and bluetooth module was installed, then the battery inflated and exploded. I was lucky that i'm not hurt but then I had no money to replace those. The warranty on this thing voided so I got no choice but to replace it. One day, I was looking for a potential replace for my headphones then I found my old nokia. It's display was damaged but the battery is still good. After 6 years of owning it, I can't believe that my Nokia battery still runs good as new. I thought to myself "why not". Also there is another problem, I don't even know how to solder a simple wire. I have the basic equipment so I need your thoughts and advice including how to do it.Note: before the battery exploded. I lost my receipt after I puchased it, without it, then I have no free warranty. Plus these thing were the last of its batch ever sold as a bluetooth portable headphone.

I'm having a problem with my Arduino IDE where I can't upload my programs. I have tried multiple version: 1.6.9, 1.6.13, 1.8.4, 1.8.5 but the problem is always there. To test each version I used a test program that should have said "Hi" in the serial monitor, but every test resulted in the following errors:If someone could please help me fix this problem, it would be grately appreciated!Thanks, Matt

Hello guys, I finally get done my Laser Engraver with Arduino, it's actually a combination of 3 projects from here, and now, at the end, my motors does not work...Here you can find the motor I use: https://www.aliexpress.com/item/Free-shipping-1PCS...I connect them on a cnc shield with A4988 drivers, I use GRBL as a firmwale and the program for engraving I don't think they matter, because I use 3 of them with no results.P.S.: the Laser is working, the M03 and M05 functions works great, but the motors not a step...Thank you and I accept any speculations, I was thinking that the current from the driver was not enough, but after a research I found that isn't true ( I think ).
