How we built a Super Nintendo out of a wireless keyboard
This is a guest article I wrote for Adafruit, on the story of how we built the hardware behind the new Sifteo Cubes, our second generation of a gaming platform that’s all about tactile sensation and real, physical objects.
S/PDIF Digital Audio on a Microcontroller
A few years ago, I implemented an S/PDIF encoder object for the Parallax Propeller. When I first wrote this object, I wrote only a very terse blog post on the subject. I rather like the simplicity and effectiveness of this project, so I thought I’d write a more detailed explanation for anyone who’s curious about [...]
Ramona Flowers subspace purse
I’m pretty new at this, and this was my biggest sewing project so far. The piping around the edges got kind of messed up in places, but overall I’m happy with the results. Front: Two layers of green denim with heavy interfacing Rear and sides: Two layers of green denim with medium interfacing Strap: Three [...]
Sewing Machine Update: LCD
I had a rather cute 128×128 Nokia 6100 knockoff LCD that I wanted to use with the project. It’s inexpensive, not a bad quality/price tradeoff, and they’re pretty easy to interface with. Spark Fun already has plenty of drivers on their page for different microcontrollers. But of course, not a Propeller. And after searching through the Parallax forums, I couldn’t find any existing driver that was open source, fast, and that actually worked with my LCD.

High Quality Zen
Announcing High Quality Zen, a batch renderer based on Zen photon garden. I built it as a way to further experiment with this 2D raytracing style, adding animation and color.
AVR RFID, Optimized and Ported to C
Way back in 2008, I posted a writeup about using an AVR microcontroller as an RFID tag. Since then, it’s been great to see many people pick up this code and build their own DIY RFID tags. In my original project, I was just interested in using an AVR as a way of emulating any [...]

Hacking My Vagina
To me, a good sex toy helps form feedback loops. It doesn’t get in the way. A good toy gives you simple ways of exchanging signals with a partner or with your own body. It acts as a conduit. A good sex toy is analog.
X-10 SmartRemote
I’m not even sure why I built this at all. I guess I did always have a childhood fascination with making things that seemed professional in some way. A simulacrum of some expensive piece of A/V equipment, or simple computer games that came in a shoe box with construction-paper cover art. This is another ancient [...]
Kiwi
Another nostalgic post about an old project that I’m purging from my closet… This time from late-1999 through mid-2000. The Kiwi was a rather ambitious built-from-scratch Linux PDA that I spent my high school years on. My original goal for this project was reminiscent of the One Laptop Per Child project. I liked typing my [...]
LEDboard/144
This is a 9×16 LED matrix I made by hand back in 2004, with LEDs I had left over from another, even sillier project. It has a USB interface powered by a PIC16C765 microcontroller, one of the first to feature a built-in USB device interface. This video post is something of a eulogy for the [...]
Duct tape RFID tag #1
This is just a messy first prototype, but I recently tried making an AVRFID tag on a substrate of duct tape. The first attempt involved: An upside-down strip of duct tape, as the base for everything else to stick atop 100 turns of AWG 40 magnet wire around a ~66mm diameter form, which I then [...]
CIA.vc service is down indefinitely
For those who haven’t seen it: CIA.vc is a web service I started about 8 years ago, as a way of Open Source projects tracking code changes in real-time over the web and IRC. This is probably going to come as a surprise to most of you reading this, but today I’ve taken the CIA.vc [...]
