Sailing the I2Cs with the Bus Pirate

Jared Boone

Jared will be discussing I2C as a bus and protocol, and will demonstrate talking with a few I2C devices. Demos may include interfacing with an off-the-shelf accelerometer, magnetometer, gyroscope, and/or audio codec.

Jared runs a fledgling open hardware business, ShareBrained Technology, where he experiments with devices for audio, time-keeping, aeronautics/astronautics/astronomy, motor sports, and radio.

Remote Reality via Orbduino

From what started as some pretty colors and cat amusement has grown to take over a walk-in closet and has had visits from all over the world. Have you always wanted to play with a robotic arm in the exotic land of Vernowhere, from the comfort of your couch? Here's your chance!

Tech junkie, traveler, and avid Phish-head. Travis conformed to the corporate mold for 17 years before breaking free to travel and completely geek out. Viva La Dork!

You!

An open-mic session for those looking to show off a project, ask a question, solicit help, or incite collaboration.


Diagnosis in a Complex World

Sun, 01/22/2012 - 03:45 — WardCunningham

After two years of service my outdoor air temperature sensor blinked out last week. Moisture was the culprit as shown here:

moisture leads to failure of ds18b20 sensor

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.

Demiduino Front

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.

ByteBeat in the Background

Sun, 12/04/2011 - 16:44 — WardCunningham

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.)

ByteBeat in the Credits

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.
