Opposable Thumbs Episode 1

The excellent Rob Ray and I have started a podcast called Opposable Thumbs. I used to organize art events with Rob in Chicago some years ago, and I’ve been itching to work with him again ever since he escaped to LA.

OT is a biweekly creative exercise where Rob and I invite a guest to set some sort of design challenge. Next, the three of us each make something based on that prompt, then Skype in to talk about our successes and failures. The first episode is out now! Here’s a preview of my project:

Prompt: Paper Clip & 2×4

In this episode I create a diegetic prototype that recruits material “flaws” (such as the knot above) to act as touch sensors. The paperclip or other wire is embedded in the wood and attached to two pins on the Arduino. Add a 1M resistor or greater and use the source code below. Right now we’re just blinking an LED, but that’s how all great things start… Please download, remix, and send me photos or video of your implementation!
