Fresh hacks every day
[Mike Li] is showing of his stair climbing robot. It's a bot that cruises around on a pair of tank treads, but some interesting modifications gave him the traction needed to ascend a flight of stairs without slipping backward. The image above shows this process in great detail. You can see the unaltered treads leaving the top of the image. In the foreground, strips of rubber-backed rug add some … [Read more...]
This isn't an airplane, it's a simulator. But you won't find it at a flight school as this labor of love is a home build of a 737 cockpit (translated) that has been going on for more than two years. It started off as a couple of automotive bucket seats in a room with two computer monitors to display the view out the windscreen. From there each piece has been meticulously added for a wonderful … [Read more...]
[Mike] picked up a cheap USB hub for four pounds (about $6) including delivery. He wanted to know how it's possible to get quality electronics for that price, and as you may have guessed it's not possible. He cracked open the power supply that shipped with the hub and hooked it up for some testing. The wall wart has a sticker on it that claims a rating of 1 Amp at 5 volts. It's pretty easy to … [Read more...]
While being caught out in the rain skiing, [Andrew] was left with a pair of soaking wet gloves. Leaving them to air dry did little good, as after 3 days they were still wet, and blowing a fan at them did little to nothing to help the situation. Luckily [Andrew] had been thinking about ways to make a forced air glove drier for some time now using standard plumbing fittings. A prototype was made … [Read more...]
If you've ever wanted to build an awesome tabletop game or model train layout scenery, you probably couldn't do better than printing Minecraft worlds on a RepRap. This guide comes courtesy of [Nudel] who figured out how to use Mineways with his RepRap. While [Nudel]'s landscape print doesn't have the full color of something from Shapeways, he only spent $3 in materials. Not bad if you'd like … [Read more...]
If you’re looking to remotely control things around the house, but can’t do it over the Internet or via WiFi, the TiDiGino just might have what you’re looking for. [Boris Landoni] from Open Electronics sent some information on the TiDiGino our way, and it certainly looks like a useful device if you’re in need of a solid GSM remote control module. At the heart of the TiDiGino lies an … [Read more...]
[Chris] has been hard at work building his own version of Simon called [Nomis]. Although [HAD] has featured an ATiny Simon clone before, the article does an excellent job explaining how the system works. The ATTiny85 is used to control this game, which, for now is laid out on a simple breadboard. A PCB version of this game has been ordered from [Seeed], so be sure to check back to see the … [Read more...]
