Ask YC: Do you have a cool Arduino project?
I've noticed that the arduino (http://arduino.cc/) has gotten quite a bit of traction, and that people are building really cool stuff with it.
Do you have a great, funny, interesting or noteworthy arduino project you're working on? Just-for-fun projects count too :-)
- rms 17y agoIn my school's product realization class my team built a prototype of a portable device used for a specific type of genetic testing, LAMP.
- timtrueman 17y agoI'm working on an inertial navigation system for an autonomous aircraft. An Arduino Mega communicates with an inertial measurement unit (six degrees of freedom, 3-axis gyros, 3-axis accelerometers), a 3-axis magnetometer, static and differential pressure sensors (altitude and airspeed respectively), ultrasonic rangefinder (for very precise landing altitudes), and a 5Hz GPS. I just completed a first flight which limited the scope of the test to a glider that kept the wings level and the nose on the horizon (using the pitch and roll data from a Kalman filter running on the IMU data updated at about 54Hz). Here's what that system looks like: http://www.flickr.com/photos/ttrueman/3770700718/ http://www.flickr.com/photos/ttrueman/3770700718/ It's a lot of fun and I highly recommend Arduino hacking to anyone that wants to give hardware a try. Here's a good starter kit: http://www.sparkfun.com/commerce/product_info.php?products_id=9284 http://www.sparkfun.com/commerce/product_info.php?products_i... One simple project that seemed cool to me was this LED one: http://blog.bsoares.com.br/processing/controlling-rgb-led-with-arduino-and-processing http://blog.bsoares.com.br/processing/controlling-rgb-led-wi... If you're ambitious you could try building your own UAV based on Arduino using Ardupilot: http://diydrones.com/profiles/blogs/ardupilot-main-page http://diydrones.com/profiles/blogs/ardupilot-main-page (I know this comment goes on and on but if you work with i2c, SPI or serial often check out Saleae's Logic: http://www.saleae.com/logic/ http://www.saleae.com/logic/ which is a cheap logic analyzer that is incredibly useful and well done.)
- mixmax 17y agoYou should check out my friend Nikolaj's project page. He has done a load of RC and electronics projects that are along the same lines. They are documented here. http://dzl.dk/projects/index.html http://dzl.dk/projects/index.html There are a few tesla coil projects too that are kind of fun :-)
- tocomment 17y agoThat sounds really amazing. I'd love to build an autonomous solar powered glider someday and have it just fly all over the world sending back data. I guess we just need really lightweight batteries first so it can make it through the night. It could seek out free wifi hotspots to use to report the data back to me.
- zeckalpha 17y agoFirst off, it couldn't be a glider, if you wanted it to do that. Secondly, a balloon might be a better option. Thirdly, http://www.thevlecks.net/rmj/earth.html http://www.thevlecks.net/rmj/earth.html It could keep up with the sunlight, if developed to be fast enough. Lastly, I would look into APRS as a better alternative to free wifi, in this situation.
- Robin_Message 17y agoI'm currently building a media center, and I'm using an arduino-derived board to control an LED display on it. I'm short-sighted, but don't wear my glasses much, so I wanted a big bright screen to do track listings and look pretty. Plus it only cost £35!

- PStamatiou 17y agoI was rather interested in Arduino for a long time (having grown up tinkering with Parallax's BASIC Stamp ][), and ended up ordering the projects kit from MAKE last month. I also got a "max m" rgb led array and am planning to make an ambient information system.. In a sense I just have this thing chilling in the corner of my room and depending on color and brightness it will convey to me different types of information. I still have to get the ethernet controller, but likely it will check for new users on my web app and if we get a lot turn red, etc... or check my gmail. one of those. http://www.flickr.com/photos/pauls/3710500813/ http://www.flickr.com/photos/pauls/3710500813/
- pshc 17y agoI've been making the feelSpace belt with an Arduino Pro Mini: http://feelspace.cogsci.uni-osnabrueck.de/en/technology_01.html http://feelspace.cogsci.uni-osnabrueck.de/en/technology_01.h... However, I haven't been able to find a cheap source of tiny vibrating motors (e.g. pager motors), so the project's at a standstill right now.
- timtrueman 17y agoIs $4.95 cheap enough? http://www.sparkfun.com/commerce/product_info.php?products_id=8449 http://www.sparkfun.com/commerce/product_info.php?products_i... For anyone that hasn't heard of Sparkfun, it's kinda of like a small Newegg for electronics projects.
- pshc 17y agoI actually bought one of those to try it out back when I started the project. But the price was more like $1.50 from the place I bought it from (RobotShop). Since then, the price has gone up, so I feel ripped off at five bucks, eheh.
- tocomment 17y agoHere are two sources: http://cgi.ebay.com/Pager-Vibrator-Motor-Bristlebot-Robot-Beam-Part-------s_W0QQitemZ190274884772QQcmdZViewItem http://cgi.ebay.com/Pager-Vibrator-Motor-Bristlebot-Robot-Be... http://www.pagermotors.com/index_files/Products/DiskL/DiskL.htm http://www.pagermotors.com/index_files/Products/DiskL/DiskL.... (Don't feel bad, searches come up with nothing!) I was reading unrelated blog posts to find these. By the way, I'm going to try building a feel space belt soon, you should email me.
- pshc 17y agoHey, thanks for the links. Only problem is, I'm Canadian, and it's tricky to find people who will ship to me... But yeah, if we could get a bulk order in together that would be great!
- lux 17y agoI'm building a 5' stage backdrop for performing (I'm a singer/songwriter) using the ledstrip Arduino library (http://code.google.com/p/ledstrip/ http://code.google.com/p/ledstrip/) and 15' of lights I bought from coolight.com.hk. So far I have a little electret microphone hooked up to it and I have the lights reacting when I sing into it. I'm still working out how I want them to react in the final version (changing colour + speed/intensity), then I'm going to hook it up to a foot pedal as well so I can trigger it selectively (e.g., during the chorus of a couple songs) and build the actual backdrop setup. The Arduino is really fun. After this I'm going to try my hand at custom guitar pedals and maybe a theremin.
- aswanson 17y agoAlso, teensy board projects would be nice to know about.
- tocomment 17y agoI got one a few months ago and just started doing baby projects. Here's my first project: http://www.blendedtechnologies.com/realtime-plot-of-arduino-serial-data-using-python/231 http://www.blendedtechnologies.com/realtime-plot-of-arduino-... It's just a knock sensor that prints a plot of the knocks to the screen. a "poor man's oscilliscope" sort of. My next project is a variation on this haptic ultrasonic hat: http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2009/rs423_jsb89/rs423_jsb89/rs423_jsb89_Ultrasonic_Haptic_Vision.html http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects... I'll post it a writeup if anyone's curious.
- Titanous 17y agoI hooked an old PS2 wedge barcode reader up to a Sanguino, so that it could store a bunch of barcodes, and dump them into LibraryThing.
