I've gotten pretty good with the "shapelock" plastic. I used it to mount/mate the usb webcam to a lego axel, and then to mount a lego gear to a couple of servo motors. And also to mount the servos to suitable lego pieces.
This design is considerably simpler and more elegant than previous iterations.
I used a 2:1 gear ration on the azimuth to give me more range of motion than the servos usually provide.
The Arduino (solarbotics ardweeny) controls the servos connects via USB to the raspberry pi. Using "screen" and "guvcview" I can communicate via serial to my sketch and aim/view the webcam via vnc. I use fswebcam to snap the occaional still photo on demand (or for time-lapse).
The usb link also provides power to the usb camera (of course), ardweeny and servos (through a powered USB hub with wifi adapter also installed and both not shown).
ATMEGA328 with arduino duemilanove bootloader on it. the sketch that's on the chip is my humidity/temperature project.

The servo motor inside the birdhouse with the little wooden wheel that is delivered with the Arduino starter pack.
I’m prototyping a new idea I call ‘wonderbots’, to see if I can bring puppets to life by mounting them on robots like the one I just built at Marin MakerSpace last night. This robot keeps moving forward until it senses an obstacle with its sonar, then it backs up, turns around and goes in another direction. It’s actually quite good at this, and comes up with some very cool moves that keep surprising you. And it's even more fun when you put a couple of these robots together in the same space, as they keep coming together, then avoiding each other.
I would now like to adapt a couple of these robots to move puppets on a stage, and see what happens when they start interacting spontaneously. My hunch is that could inspire a sense of wonder, if we also add a good storyline, a nice backdrop, a few lines of dialog, lights and sounds. For my first experiments, I’d like to play with masks on wheels, as well as animals on wheels — hence the mockup with one of the ducks that Dr. Canard made for us. I can’t wait to see them in motion. Stay tuned ...

I wanted a logging thermometer for my living room to track temperatures after I go to sleep, to get an idea for how my fires are doing. I wanted one that was inexpensive, so I built one with an Arduino! Do not be fooled into thinking I know what I'm doing.
On the laptop side is a short python script I wrote using pySerial and sqlite to read and record the temps.

This is my breadboard-compatible Arduino clone. The USB circuitry is based directly off the Duemilanove and has the same power supply switching circuitry as well. Get the design files here: bit.ly/H63sCW
It's a bit of foamcore board glued to the back of the machine, with the arduino board tied to it with a piece of wire. Subtle stuff, non?
This is an Arduino project that uses the Parallax RFID reader. I managed to get it all to fit inside of Sparkfun's project box. It's was a little tight, but ended up working great. I'm using it as a serial device with a WPF based application to read in tags and identify tagged objects.

Crude tone generator - not really a theremin though. Uses a potentiometer to control the pitch and button to turn on/off.
