Many factors helped birth the HypnoLamp: At Toorcamp 2012, I learned to program microcontrollers. Jeff of Olympia Circuits blessed me with addressable LED strips, at the aforementioned event. Jeff was also at the Portland Mini Maker Faire, showcasing (among other things) glass Ikea lamps with LEDs inside. I decided to build my own version!
Here's some details of my radio spectrum analyzer hack at Maker Faire. But first, a quick video of the hack in action:

The Arduino IDE editor's lack of support for X11's select-paste mechanism has always annoyed me. Well, I finally got around to adding it. Especially for helping people with their Arduino troubles (which I do every day), it's so very nice to finally be able to quickly select-paste between Arduino and forum messages, email, terminal windows, etc.
This is a Unix/X11 feature. Mac & Windows do not have anything similar. But on Linux it's so very fast and convenient. This tiny little feature really makes me happy. :-)
Update: it's been accepted and will become part of Arduino 1.0.5. Anyone using 1.0.4 who wants this feature now can install Teensyduino 1.0.4 release candidate #1 to get this feature without having to recompile the entire Arduino IDE.
Over the last couple weeks I've been working on a automated test system for Teensyduino, which someday will verify nearly all the Arduino functionality on every board and also test most of the Arduino libraries. Here's what my first try looks like.

Thanks to everyone that presented (especially the new folks during OpenDork) and to thanks to everyone that came out!

Use MAME's debugger to reverse engineer and extend old games
For the Church of Robotron's installation at Toorcamp 2012, we needed to be able to trigger physical events when game events happened in Robotron 2084. A quick summary for context:
We choose to use MAME's debugger to detect game events and notify other pieces of software when they happened. This is a quick tutorial for others (and a reminder to ourselves) if you're interested in doing similar things. We're going to find out how to detect player death!
A few months ago I was feeling inspired to create a nice countdown timer. With the next Dorkbot open mic only days away, I finally had the motivation to actually put it together...

Self Balancing Robots 101
Glenn's presentation will cover the basics of self balancing robots:
Glenn Phillips got into the computer business around the era of the Mac Plus. Glenn's last job was the owner of Gorge Networks Inc. a rural Internet provider using fixed wireless and dsl. The business was sold in 2010 and Glenn has been on the Obama plan ever since.
Glenn became interested in the Arduino a couple years ago, but he had no programming experience. At some point in the process Glenn began to control servos and motors from his old RC collection. Computer control of motors was fun, interesting and possibly a job in the future.
Self balancing robots seemed to be the holy grail of motor control! Constant feedback from sensors is processed and translated to power and direction of the motor. Any issue with any component of the system is immediately apparent.
Glenn is also a cheap Yankee so his creations use salvaged parts from electric bikes, scooters, wheelchairs, laser printers and computers.
