Anyone remember the days of DOS games "playing" music by moving the floppy drive heads? Well, I had to test a new robot platform, but I was too lazy to go build an actual frame with a pair of wheels. So what can I do to test the motor speed controls with nothing to move? Watch.
These are the control boards that we'll be using in the Robotics Workshop at this year's Euskal Encounter 15, in Barakaldo, Spain. This is one of Spain's largest LANParties, with up to 4096 people attending this year.
Oh, yeah, and it's in stereo too :) (melody on the left, bass line on the right). Not bad for 18 hand-tuned notes.
New in v2.0 (also known as next-afternoon version) - MIDI interface! On a sidenote, this could be really useful for an actual robot - you could program movement commands using MIDI sequences.
