DIY MIDI Sequencer
Not much written about this excellently crafted build from Flickr user Collin Mel however he does mention he’ll have a parts list posted in the future.
On the Flickr page Collin links to his source for the LED light bars. I checked the link and the product wasn’t found. What I did find find though was these awesome Playstation 2 thumb joysticks which could be easily rigged up as a midi controller. only $3.90!
