thingstruments

Here's some Arduino powered synth magic for you. frauAngelico is a drum synth / sequencer, Standuino Pi is a drone synth and the microGranny a cool little granular sampler. Mix them up and you've got this:

I really have no excuse for not introducing the Teenage Engineering OP-1 until now. It first gained fame being featured in the swedish house Mafia's music video for "One (Your Name)" . It's a quirky portable music workstation. Here's one example of the OP-1 in action: And here's a tutorial to the ridiculous and wide accessories range, which makes the OP-1 even more a real Thingstrument. The unit currently costs 800€, so it's not the cheapest toy you can get, but it can really do quite a lot for the buck.

Another Arduino made instrument: the Bleep Drum. See Bleep Labs' store for more info . A kit will cost you $60.

The Optigan was a 1970's organ based on optical rotating discs. In fact, it was much more than just an organ: it was more like a sampler. You could even play pre-recorded beats with it and more. The problem is that the Optigan is very rare nowadays. However, the discs are still available... ...so Gan at gaje.jp decided to make his own Optigan. Very impressive! Here's the video!
