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).
When: Sunday, February 23rd, 2014. 1-5pm
Bring: A laptop and headphones
Instructors: Jesse Mejia, Alex Norman, Jason Plumb, Edward Sharp
I like to put my projects on Instructables and I wanted to share this recent post.
Its 2.5V 10F Super Capacitor, Solar Charged, and Attiny85 charge controller and LED blinker.
I'm working on an SMS device that is programmed in the Arduino IDE and uses a tiny chorded keyboard for input, a SIM900 GSM module to accept standard AT commands, and a Nokia5110 LCD to display output. I stopped by earlier this evening and Paul (thanks Paul!) helped me debug. I've posted a thread on the Arduino.cc forum http://forum.arduino.cc/index.php?topic=206415 but basically I'm having trouble getting my sketch to run in the tiny 2K of RAM available on the ATmega328.
