Hasta La Gadget!

There are three things that will guarantee your DIY project some attention: slap it on a Roomba, base it on Arduino, or make it tweet. Do all three and, well, you’ve got a nerdgasm-inducing bit of Make fodder. The creation you see above is a web-controlled tweeting Roomba whipped up by Instructables member matchlighter using a 500 series vacuum bot and the Sparkfun WiFly shield for Arduino. The autonomous cleaner can be triggered from anywhere there’s an internet connection and updates Twitter to keep you abreast of its status (Ahh! Dock sweet dock). While Mr. matchlighter was kind enough provide directions for building your own, a lot of the actual coding is left up to you. (We’re lazy, let us just copy and paste dammit!) If you think you’ve got the programming chops, hit up the source link for instructions and check out the original’s Twitter feed at the more coverage link.

Update: The complete code is in step eight of the Instructable.

Jealous of your Nexus S-owning friends and their fancy NFC chips after yesterday’s Google Wallet announcement? Well tech tinkerer Joe Desbonnet has whipped up what he dubs “poor man’s NFC” using an Arduino, some magnet wire, and any compass-equipped Android smartphone (which is almost all of them). By placing a coil of wire on the phone and connecting it to the DIYer’s favorite microcontroller, Desbonnet was able to send data, albeit very slowly, to his HTC Desire running a special app to decode the signals. Granted, you’re probably not going to see American Eagle mod their point of sale systems to talk to your phone’s magnetometer, but it’s still a neat trick. In fact, we’d break out our Arduino right now to give it a try, but our secret lair is strangely devoid of enameled copper wire. Check out the source link for instructions, and don’t miss the video after the break.

The rapture has come and gone, but the Maker Faire powers on. Despite warnings of a May 21st doomsday, folks came out in droves for the annual celebration of all things DIY, and we were there to bring you the best in homespun inventions. This year’s Maker Faire was light on robots and big on corporate sponsorship. Among the giants supporting the little guys were Google, ASUS, and HP, but El Goog’s presence extended beyond its dedicated tents. The new Android ADK was big with at-home tinkerers this year, spawning a number of little robots and at least one DIY alternative.

Perhaps no other trend proved more pervasive than 3D printing, however — every time we turned around there was another MakerBot or RapMan pumping out everything from statuettes of attendees to cutesy salt shakers. There were robotic building blocks, a Heineken-themed R2-D2, DIY drones, custom keyboards, and a ton of repurposed gadgets, but it was an arena of destructo-bots, tucked away in the farthest corner of the San Mateo County Event Center, that really blew us away. We came away sunburned and bedraggled, but lucky for you, we did all the dirty work so you don’t have to. To see what made this year’s Maker Faire, hop on past the break for a video of our favorite DIY finds.

The future of marching bands is about to change. And although that might not sound very exciting to those of us who aren’t marching band aficionados, an impressive new technology may change not only the way marching band music is played, but also instruments of all kinds in the future thanks to an open-source project […]
