the operator of a MIDI calculator
[…] is a demo of a project I built so that I could use my HP 48 to play a MIDI keyboard. The calculator is running a program that sends data to a Parallax Stamp Basic microcontroller over the built-in serial port whenever I press a button. The microcontroller is running software that converts the message from the calculator into a MIDI noteon or noteoff message that is then sent to the keyboard. This is a response to a createdigitalmusic.com poll in which a (small) number of users said they […] read

PIC-based laser light show
This is a really cool laser light show that can display vector images via two high-speed galvo scanners. This isn't a simple DIY project, but there is a lot of information and source code available to help you get started.

A hard drive hack for turntablists
[…] sits at the center. The weight of the disk plus the quality of its bearings won the crew over, and with "a few op amps, resistors and a programmable microcontroller of some kind" you too can be mixing in no time. Full instructions are at the read link, and check out the video below for a little platter-scratchin', oscilloscope-watchin', "wicky wicky" action.[Via Hack A Day]Continue reading A hard drive hack for turntablistsA hard drive hack for turntablists originally appeared […] read

Open source handheld game kit: Meggy Jr
[…] and Chris. Meggy Jr RGB is a new kit that we designed as a platform to develop handheld pixel games. It's based around a fully addressable 8x8 RGB LED matrix display, and features six big fat buttons for comfy game play. The kit is driven by an ATmega168 microcontroller, and you can write your own games or otherwise control it through the Arduino development environment. Meggy Jr is fast, programmable, open source and hackable. And fun. Kit prices range from $65 to $95. Meggy Jr RGB... read

HDDJ - hard disk for rotary input
[…] voltage. The answer is yes - and it's a very simple process to turn a hard disk into a rotary input device that has some unique properties. All you'll need is an old hard disk drive, a few op amps, resistors and a programmable microcontroller of some kind.Nice pushbuttons!

Turn Your Broken CD Case Shards Into Mini LED Light Sabers For Your Wall [DIY]
[…] Keith Neufeld created a really cool lighting system for an art installation, which could just as easily find its way onto your wall at home, if you are one for soldering and breadboarding. The whole thing is wired to a microcontroller that can cycle the lights on and off in sequence, and eventually respond to user interaction in the finished piece. Just be sure you don't strike yourself down with any jagged edges. [Keith's Electronics Blog via MAKE] galleryPost('cdtrayLEDs', 3, ''); read

SV Chronometer – a GPS based, interactive master clock
[…] about a device I built to provide me with an accurate time reference I can use to synchronise all the timepieces in my house. It used a GPS module and a PIC 16F628 microcontroller with a small two line LCD screen to display the time (UTC and local). Everything is housed in a art deco style casing with eye pieces to peer into the inner workings of the device. A crank handle on the side must be turned to cause the display to light up in a flickering manner similar to and old mutoscope […] read

Bare Your Solio To Me, Arduino
Jonah over at MAKE points out that you can actually make your Arduino a lot greener. How? Use a Solio with an external USB cable to provide your favorite microcontroller with power. If you don’t know what a Solio is, it’s essentially a small solar powered gadget charger. While this isn’t exactly a breathtaking hack [...] read
