Stumbled on this awesome project that uses 2 old hard drives platters as rotary encoders / jog wheels. Obviously for the purpose of DJing! I love it when people reuse hardware that was originally intended for another purpose.
The build uses an Arduino Mega 2560 as its main processor. RGB LED’s for the VUmeters, some slider pots for fading, and some extra buttons and knobs for MIDI events. On the PC software side, the author is using mixxx for the MIDI mapping.
Check out the video after the break. More pictures in the gallery. Source code here on GitHub. More documentation here.

Tim’s got a pretty cool sounding home made synth, he calls it the cheapsynth. He is using a keyboard from the game rockband on the wii, and an arduino. Amazingly these keyboards have MIDI on them already so technically this hack should work with other MIDI devices.
Currently it looks like it supports 2 note polyphonic output with options like square, saw, and portamento. I’ll be honest I’m impressed with the sound coming out of this. I’m off to eBay to buy one of these keyboards myself and put this together. :)
Source code to the arduino sketch is available here on github.
