[Scot] whips up breakout board for his ARM breakout board

Posted: December 23rd, 2011, 1:30pm MST by Mike Szczys

[Scot Kornak] got his hands on the new STM32 Discovery Board. He got his as a free giveaway, but at only $18 he probably would have picked one up anyway. His one complaint about the device is that he dual pin-headers which break out the ARM processor’s pins are not the most convenient for hooking [...]
A vacuum chamber from a pressure cooker

Posted: December 23rd, 2011, 12:30pm MST by Brian Benchoff

[Allan] needed a small vacuum chamber to get all the air out of clear casting resin. Degassing is a simple step in casting that improves the finished product immensely. The problem, though, is building a vacuum chamber. [Allan]‘s chamber seems easy enough to build, and pulls enough air out to get to 0.1 atmospheres. After [...]
Snap together boombox great for taking your music on the go

Posted: December 23rd, 2011, 11:30am MST by Mike Nathan

[Matt Keeter] wanted to take his music on the go, and wrote in to share a great looking boombox he built for under $100. His goal was to put something together that could be made in pretty much any hackerspace/fab lab, so his boombox was made using simple materials. He first modeled the boombox using [...]
Animated LED buckyball

Posted: December 23rd, 2011, 10:30am MST by Mike Szczys

This animated LED buckyball has little to do with modeling a carbon molecule but a lot to do with adding some excitement to your party decor. [Tim] felt that the LED cube hacks had run their course, so took on the challenge of a sphere made out of pentagonal and hexagonal components instead. As with [...]
Make any scrap of paper sticky with 2000 volts

Posted: December 23rd, 2011, 9:30am MST by Mike Szczys

Who needs chemistry when a little bit of physics will do? Instead of brewing up a batch of weak adhesive to make his own post-it notes, [Valentin] built this handheld device to add an electrostatic charge to bits of paper. Just give them a couple of seconds to charge and they’ll stick to the wall [...]
Bitbuf delivers some of the best chiptune effects around

Posted: December 23rd, 2011, 8:30am MST by Mike Szczys

Wow. And furthermore, WOW! Just looking at that clean prototype you know that a lot of work has gone into the project, but when you hear this chiptune MIDI device you’ll really be impressed. We know what you’re thinking, but really, you’ve got to hear this to appreciate the quality [Linus Akesson] achieved in this [...]
Xbee Wireless Servo Control

Posted: December 23rd, 2011, 7:28am MST by Jeremy Cook

Servo control is good, but wireless control is even better. This hack by [PyroElectro Tutorials] shows you how to do this wirelessly using two Xbee modules. There’s also a great example in the video after the break of this “hacking platform” used to control an animatronic head’s eyes. (we’ve featured the eyes here before). In [...]
