Hacks
HiJack power and bandwidth from iPhone headset port
Project HiJack is an elegant take on an old idea. Ye-Sheng Kuo, Thomas Schmid, and Prabal Dutta from the University of Michigan’s EECS Department have done the iPhone hacking world a solid by producing one of the coolest little pieces of kit to come around in a long time. In short, the device can pull several milliwatts at 3 V and communicate at 8.82 kbaud using the iPhone’s headset port. Its design encourages the use of daughterboard peripherals to sense and collect data.
Tint ABS feedstock with a felt marker
Thingiverse contributor theorbtwo found that a simple felt marker is all it takes to tint the output from a 3D printer, so they designed and fabricated a holder for those interested in giving it a try. If you do attempt this, be forewarned that some markers may clog nozzles, so verify compatibility prior to a print run.
Stuxnet Worm – BYOC, bring your own centrifuges
This crazy story is making the rounds, it appears a virus was specifically designed to spin nuclear centrifuges. In order to do this, the virus writers most likely needed to reproduce this with the actual (duplicate) equipment… The worm itself now appears to have included two major components. One was designed to send Iran’s nuclear […]
Quiz-O-Tron 3000 Arduino quiz lockout system
If you’re an aspiring Alex Trebek with some Arduino skills, you should check out RoysterBot’s Instructable on how to make a Quiz-O-Tron 3000, an electronic quiz contestant lockout system, which allows contestants to “buzz in” during trivia games. He used it at a holiday party and therefore needed something sturdy enough to withstand the hand […]
Deodorant-stick linear actuator
MAKE Magazine subscriber Jeremie Boulianne of Calgary, Alberta, came with a unique way to build a linear actuator: Linear actuation is an elusive and expensive field to get into but I always seem to find a need for it with robots I build. Whether it being to raise a turret or dispense a marker a […]
Kinect talking to Flash via Node.js
Wouldn’t it be cool to use a Kinect to interact with that fancy rich user interface you just whipped up in Flash? Well, prepare to be stoked. Interactive agency BLITZ has got you covered. Check out their demo video above. Word has it that they’ll be dropping source code today.
