Fresh hacks every day
[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 up external components. He decided to make his own breakout board which would give him a more robust … [Read more...]
[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 a hole was drilled in the side of the pressure cooker, [Allan] installed … [Read more...]
[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 cardboard, later fabbing it from wood on a laser cutter. The design allows the stereo to be … [Read more...]
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 many LED projects, finding a good diffuser is paramount. [Tim] decided to go with hot glue … [Read more...]
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 with ease. The charging circuit is pretty simple, involving a transformer, transistor, resistor, … [Read more...]
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 synthesizer. You can catch it after the break. He does a great job of showing off … [Read more...]
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 this control scheme, communication is one way only. An Xbee module is … [Read more...]
