Check out this 6-pin MSP430 microcontroller. What’s that you say? TI doesn’t make a 6-pin MSP430? True, Texas Instruments doesn’t make one, so [Greg] grabbed his Demel and a cutoff wheel, and chopped up a larger uC to arrive at this package. It may sound a bit crazy at first, but when you think about [...]

[Greg] is really working on a small scale with his LED Matrix backpack PCB. It’s a toy that he designed as an activity. He constrained himself to a board which would exactly match the outline of an 8×8 bicolor LED matrix package. What you see here is the side of the PCB which will be facing [...]

[Greg] was looking for something to build using his recently acquired Arduino, and with Halloween approaching, he thought a cool light display would make a great project. He browsed around online and found this tutorial that shows how to build a chorus of singing pumpkins controlled by a computer’s parallel port. Since he didn’t have [...]

[Greg Intermaggio] and [Shumit DasGupta] at Techsplosion launched a high altitude balloon last week that climbed to 90,000 feet above sea level somewhere over California. The play-by-play of the flight is one of the better stories we’ve seen on high altitude balloon builds. The balloon, christened VGER-1, carried a SPOT satellite GPS messanger to send telemetry back to the [...]

[Greg] built himself a small indicator dial with his laser cutter, and wanted to use it for visualizing server performance and load information. Before he started using it for server monitoring however, he thought he should test out his data parsing skills on a simpler data set. Pachube has a wealth of information that can [...]

If you’ve ever had a water leak in your home, you know the sinking feeling that comes over you as you walk through the door to the sound of running water. [Greg] knows this feeling quite well, having returned home to a sopping wet floor and an overflowing reef aquarium on more than one occasion. [...]

[Greg] sent in his biometric pistol safe lock. He keeps his guide light on details so not every Joe can crack the system (there is a thread to sift through if you really wanted to), but the idea runs fairly simple anyway. [Greg] took an old garage door opening fingerprint scanner and wired it into [...]

[Greg] managed to clone a SEGA Genesis using a field programmable gate array. He used a Terasic/Altera DE1 board, which will set you back about $160, during development. The onboard push buttons are currently used as the controller with VGA for the display. Who knows, maybe there’s enough programming space left to drive a PSP [...]

[Greg] has been working on a version of Debian/ FreePBX/ Asterisk for people to be able to drop onto a SheevaPlug. If you haven’t seen it, the SheevaPlug is a tiny computer housed in a wall plug. They made some waves when they were announced last year, and we’ve spoken of them several times. [Greg] [...]
