I'd been meaning to do this for a while, and when I got a bag of colorful little breadboards, it was TIME.

ByteBeats Clean w/ Teensy-3.1

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.

Maker Faire 2014

Maker Faire went really well.  I had a booth about the new audio library, and we also built a OctoWS2811 LED display for Freescale's booth.

Anyone recommend a beginner 3d printer?

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.

A Music From Very Short Programs Box

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."
