 Color Pong -
A nice picture frame that has a pingpong ball that changes colors via tri-color LED. It also has user input dials to allow you to specify the red/green/blue values, or close a switch to have the firmware slowly change the values. A nice conversation piece hanging on my cubicle wall at work.

 Overboard -
A daughterboard/PCB that provides output in various forms (LED, Audio, LCD Character Display). Useful for debugging other
circuits and microcontroller firmware. Currently in version v0.1, Overboard is not very useful yet, but lots of fun to build.

  Philly - The first
robot I ever built from scratch without following any instructions or kit. That's not to say I didn't have any help
from a variety of robot email groups and other enthusiasts. Philly is a line follower at heart but has some
other fun options on the way. His mission in life is to race Sandwich around the Basement Oval. Along the way, I built an
ATtiny26 prototype board as an experiment in PCB fabrication.

 Symet - My first robot was a Symet, as described in the
book Junkbots, Bugbots, & Bots on Wheels, by Dave Hrynkiw and Mark W. Tilden. Sy is a fun, simple project
great for a beginner or someone who is learning about BEAM robots. Click on the Symet icon to learn about
one of the many uses for an old hotel room key.

 Sandwich - The second robot
I ever completed is a Sandwich robot, as described in David
Cook's first book, Robot Building for Beginners.
Sandwich is a simple line following robot who can follow either a dark or light line, thanks to a
DPDT switch. There's lots of eye candy on this page and some video of my Sandwich following some
lines and playing with a dog.

 Roverbot - The next robot is a Lego Mindstorms Roverbot. The Lego
Constructopedia describes how to build this sturdy robot base, complete with modular/interchangeable
drive train and sensor mount. The challenge is to write the software. In its first iteration, Roverbot
is a line following robot, because Sandwich needed some competition.
