Dangerous Prototype's Bus Pirate, several members of our humble band have decided to put together a group order for components to build out own Bus Pirates.
As of this writing, our component and PCB order totals more than 10 Bus Pirates. The greater number we have, the better the component prices (in many cases) will be.
Why are you doing a group order instead of just buying them? The easy answer is of course price.
Using Elco Jacob's ShiftPWM Arduino Library. Probably the cheapest possible way to drive lots of RGB LEDs!
(EDIT: added PCB files)
EDIT again: documentation is now available here.
After two years of service my outdoor air temperature sensor blinked out last week. Moisture was the culprit as shown here:
Various readouts in my SensorServer system lead me straight to the problem through a half-dozen layers of software. How cool is that?
Honestly, I'm more interested in how we know and trust complex measurements than knowing the temperature outside.
My SensorServer software worked so well that I prepared a Keynote presentation explaining each diagnostic step along the way.
Last night I finished assembling and uploading a sketch over USB to Demiduino. At half the dimensions of an Arduino, Demiduino is a small, portable, and affordable Arduino compatible with the Leonardo bootloader.

Bytebeats radically reduce the already austere chiptune music to one-line formulas. When wrapped with a dozen more characters of C code these formulas will feed your sound card endlessly. Musicians speak of discovering bytebeats, not composing them. I've used a bytebeat dubbed Crowd as the background score for a one-day film shot yesterday. Note that I include the entire discovery in the film's credits (disrespectfully broken into two lines.)
Kragen has written a good summary of the short history of bytebeat with links to catalogs, videos, analysis and especially interactive tools for exploring them.
Where: ADX, 417 SE 11th, Portland
When: Sunday, November 27 -- 1-5pm
Portland Synth Meet is a gathering for audio synthesizer enthusiasts. It's a chance for makers and collectors to show off their gear, share notes and make sounds. Synths of all kinds will be represented including modular and desktop synths, drum machines, circuit bent instruments and algorithmic one-liners. Anything that can synthesize or manipulate sound is welcome. Bring your own speakers and power strips. Local synth makers will offer demos at the top of every hour.
