I'd been meaning to do this for a while, and when I got a bag of colorful little breadboards, it was TIME.
Here's a clean version of the ByteBeats circuit we built last Sunday. I used a Teensy-3.1 instead of a Teensy-2.0, but everything else is more-or-less the same. (I added some capacitors on the power lines, a volume control and a speaker instead of the headphones, but it's all minor changes that anybody at a Dorbot meeting could help you with. Or email me, I'll go through it with you.)
The ByteBeats workshop went pretty well: everybody left with a working circuit, although there were some hiccups along the way.
I hope you all enjoyed the project. Keep in mind: the same circuit can be used for a bunch of different audio hackery by changing the software. For example, I wrote a program to produce sine waves at regular musical-scale intervals. It's a short step from there to playing MIDI, I imagine.

Hey everyone! I'm the lead organizer for the Portland Indie Game Squad. Our funding project recently surpassed most of its goals – which are all resources being made available to the community – and I'm coming up with some higher-tier options. A 3d printer is definitely on my list for the board game/miniature game developers in the group, and I've been asking around for what people might recommend as a "beginner" setup, somewhere between $400 and $600.
This weekend my friend Jacob S. and I built a Arduino based music box to play Ville-Matias Heikkilä wonderful one-line C code that makes surprisingly complex "Music From Very Short Programs."
DorkbotPDX is happy to offer a free workshop as an introduction to Pure Data (Pd).
