Hey everyone, I need some help for my project paper. I want to build a self-balancing "one wheel". But I dont know where I can buy a wheel hub motor. I searched on Alibaba and found some fitting ones. A 800W 48V DC Brushless (Wheel Hub-) Motor. But i don´t know which speed motor control is the best for this type of motor. I want to use an arduino uno ! Can someone please Help me finding a motor control ? Thanks a lot :) PS: Sorry for my bad english :) I am german

A news report on CNN describes a teen-ager who, in her high-school science class, diagnosed her own Crohn's disease by catching a granuloma on a microscope slide she was studying.As a "teachable moment" for good science education, it's great, but I'm not sure having to diagnose one's own disease is really what "do it yourself medicine" is meant to be about!

The cup doesn't really stir itself on its own, but it has a ball that fits into a groove that can be swirled around to mix up your tea and sugar. It's a funny concept that's looking for a manufacturer, but is there a problem with stirring out there that I'm not aware of? Also, do you want to be swishing HOT tea in your hand in the morning before you've really woken up? Sounds like a noisy recipe for disaster to me and that's assuming you can keep the ball and cup together after a couple of washings. Linkvia Neatorama

I'm looking for a cheap version of the self winding watch winders like they have at http://www.ewatchbox.com/stsiwawi.html. I haven't found anything under $70! I searched this site and couldn't find anything either.So here's a challenge for you gadget gurus out there that think this might be something fun to make!I look forward to seeing what will pop up here!JM

As I searched for something on health, and didn't find one. Of course, the normal caveats are true, since none of us are able to diagnose or treat disease, this is only to point one in a possibly correct direction.

I'm starting to plan a self-balancing unicycle and I notice several people that have built them are using 450-500W motors. I'd like to use something a bit more robust, like 750W @ 24v, due to terrain. I'm wondering if that's too much and if the guys that are using 500W are happy with the results? Has anybody tracked their current (amps) usage? My guess is that unless you're going full speed and uphill you'll rarely hit full wattage on your motor except for temporary instances. One of the challenges I'm finding is that there are motor drivers up to 25A at 24v or 36v that can handle a bit of surge, but then it takes a huge leap to 160A and 400A surge. I don't think I need something that large and expensive, but my electric motor experience is limited. Could some of you more experienced guys chime in with a bit of advice? Thanks, Gyv

Hi Forum. My wife and I have just purchased a piece of land. It was a stretch but the plan is to check out of the rat race once and for all. What we are looking for is ideas, plans, resources, links etc for a DIY home that won't require a mortgage from hell. Any and all ideas greatly appreciated. Also interested in looking at prefab as an option. Thanks. Thoughtfission.

Curious observation from my mother's recent 3 months in the USA, she says she is unable to bake well when she was in the USA. Now, given mum is a pretty amazing baker on this side of the pond, I am wondering why that might happen ? I wondered if its "American flour", as opposed to "UK flour" - the recipe, would be the same kind of things, memorised over the years, like a simple scone, fairycakes, pastry. Her main complaint was that items didn't brown, even at the same oven temperatures as she uses here, and after repeated experiments with the same recipes.

Houston, we have bug zappers! No really, just this time with lasers! I was surfing through Hack-a-Day, and I came across this. These devices identify a mosquito by the frequency of its beating wings. Once identified, the device aims a laser and destroys the little blood sucker. That seems simple enough, so: Do you think that this could be accomplished by a DIY for under $100? think about, we may have a really useful Instructable on our hands.

Hey Everybody, I'm new to the community here, and i am hoping that with so many great minds on this site, some great ideas will be generated. the deal is, for a competition, my school needs to build a small car, around 1foot by 1foot, and it is propelled by three average sized rubber bands, it need to travel three meters straight, make a 90 degree right turn on the spot and travel 2 meters to stop in a parking zone, it has to turn and do the whole course unaided, Any great ideas? Thanks for helping me out

Instructables member XenonJohn has had his Self-Balancing Skateboard featured on New Scientist TV, using video taken at the UK Maker Faire. I had the pleasure of meeting John at the Faire, and I can safely say that this world needs more like him. Kudos, John.

From Wired:"In just over a day, a powerful computer program accomplished a feat that took physicists centuries to complete: extrapolating the laws of motion from a pendulum's swings.Developed by Cornell researchers, the program deduced the natural laws without a shred of knowledge about physics or geometry. ...Condensing rules from raw data has long been considered the province of human intuition, not machine intelligence. It could foreshadow an age in which scientists and programs work as equals to decipher datasets too complex for human analysis."LinkThe software has a long way to come, but apparently it's showing a lot of promise.What do you guys think? If computers can do physics better than humans, does that make human physicists obsolete?

So, there are a lot of people posting articles on how to make tasers, most of these only spark if they touch something conductive. I would like to ask, how can you make the current jump between the two wires without touching something conductive? thanks

Why is the home page always changing format? It looks more ridiculous every time! I remember when I first joined how their was two collums of different instructables. This format was easy to sort though and you didn't have to look through all the stuff you DIDNT want to see and you could click on the vast variety of things you DID want to see. Today when I logged on there is only one column of things and I cant even sort out what is recent and what is featured. Please change the format back instructables robot. It is a lot simpler and looks more professional. EB

Hi, I was watching a video for a self watering system for plants (link below), and was wondering what the science behind it is called. I also had a problem where no water came out of the bottle because the hole I made at the bottom was too small. As soon as I unscrewed the cap a little, the water came gushing out. https://www.youtube.com/watch?v=Ffe7JfYyBFE Thanks :)

Hi All This is my first post, so I apologise in advance if I've selected the wrong category for the post. I have an idea... I have a quad-copter at home that I'd like to attach a small light weight item and have it self release/open after 2-3mins. Ideally, either a small springloaded clip based on the rough image below or something similar, that is self opening after a selected timeframe, even after 1-2mins, or alternatively, a small lightweight mechanism that does the same thing. I've searched everywhere and can't find anything even close; lots of small clips, hook, latches, but nothing that 'self-opens', which is the most important spec. I can add a new RC servo and swinging arm and operate the release by remote, but I want to avoid it if there's a simple solution out there. Appreciate any help if someone has seen something out there?

Hello, I am interested in making a energy source similar to iron man's arc reactor in the fact that it is small, self contained, and and powerful. I would like it to be hand-held, but I can deal with slightly larger or even desk size. It needs to be long lasting. I am well aware that an arc reactor is fictional, but I just need something that may be similar. It can be a large project (I have time) but needs to be not super expencive. Around $500 is the max I can go for! I hope someone can help, 13islucky

Hello everyone in this wonderful community! I want to share something to see what you think about it! When I finished high school in February last year, my family gave me some money as a present. I put all that money into my new computer. However, I had no other place to put my computer than my work desk. I need this desk for many other things, such as airplane modeling, drawing, designing, soldering, and such. Therefore I have to get a separate desk for my computer. I always enjoy making stuff myself, so I thought that I could design my own desk. So, this is what I came up with. The desk I have designed has a contemporary, extravagant look, and is NOT designed to save space! It will be made of MDF and have a dark glass top. No drawers or shelves needed, except for the keyboard and the mouse. It will be wall-mounted. The MDF will be painted black. I have made the design in AutoCAD 2007 in 3D to see what it will look like, these are the renders I made, of the complete desk, of the structure, and of the pieces needed. --------------- I am not sure of the thickness of MDF and glass that I should use, or if the structure is too heavy or too weak. (I have a desktop computer, not a laptop) Please help me with this part! --------------- If I ever build this, I will make an Instructable of it! Please take your time and say what you think of the design! I will greatly appreciate it!

Does anyone else here feel like they might as well have a full time job at instructables? I need some kind of Instructablers Anonymous group. I wouldn't be surprised if I spend 40 hours a week on here. (Can any of the staff members check that for me?) Anyways...I'm sure I'm not alone here...

I am looking at making a self balancing skateboard... i am having trouable finding step by step instructions for the ones that use the sensors... so i was thinking that if i could use a wiimote or a ps3 controler becuase everyone knows that the wiimote has gyroscopic sensors in it and the ps3 controller has a sixaxis thingie in it...(i know that thingie isnt the correct term for it...) so that gave me a good idea instead of piecing together gyrocopic sensors and many other things than why not just use a controller to control it... and if anyone knows another way to control a self-balancing skateboard... or a way to hook them up to the board... and i am not very good at programing so... if you could just send me a message of the programing to use the controlers as a controller than that would be great... if anyone thinks that this way is just to much harder than it seems than please tell me... thank you, Girrrrrrr2
