Fresh hacks every day
[Chris] sent us this fantastic tutorial, introducing beginners to H-bridge motor drivers. While many of you will consider this stuff basic, those who are trying to expand from building only things the arduino board can handle to bigger more expansive (and powerful) projects will find this quite helpful. [Chris's] tutorial is very in depth, not only going through the … Read the rest
[Retromaster's] Ultimate Floppy Emulator is a wicked display of hardware mastery. It is the culmination of several design stages aimed at replacing an Amiga floppy drive with a modern storage solution. You may be thinking that using an SD card in place of a floppy isn’t all that interesting but this hack does much more. The board, controlled by a … Read the rest
As you can see above, there is no wiimote in that accessory steering wheel. There is, instead, a home-made accelerometer controller that connects to the pc via USB. Based around a PIC 18F2550 and a 2 axis accelerometer, this device is detected by windows as a standard controller. The schematic and source code are available on his website. He says … Read the rest
Wireless headphones can be a wonderful way to help clear up the clutter inherent in most desktop PC systems. However, after plugging a wall wart in, and the headphone jack into the computer, the number of wires used has actually doubled. After [Parker] found an old set of JVC 900 Mhz wireless headphones (and a generic 900MHz transmitter), he cracked … Read the rest
[Jerry] lost his finger in an accident and has since added a prosthetic USB flash drive in its place. It’s making the best of a bad situation; there’s nothing wrong with a little voluntary cyborgization. At least it’s not as invasive as some of the implants we’ve seen before.
UPDATE: Here’s the entry on [Jerry]‘s personal blog.

What you see above is the culmination of [Zach Smith]‘s work building a pinch wheel style extruder for the RepRap. The current RepRap 3D printer uses a screw mechanism to push 3mm polymer filament into a heating barrel where it is melted and then extruded through a fine nozzle. [Zach]‘s new version uses a drive gear from SDP/SI mounted directly … Read the rest
Maybe you wiped your iPhone by filling the hard drive with music, or maybe you used a more sophisticated method. In either case, your phone is clean, but the hard drive in your computer is still chock full of evidence of your misdeeds (or just personal emails to your mother). If you fear forensic analysis will expose your … Read the rest
