This project is still in progress, but my son and I completed our first pass on testing the code so I wanted to go ahead and post it and will update it with the final code and build of materials as I complete them. The details for the project are at http://jarrodsinclair.wordpress.com/.
Here is the main timer:
Video I posted on my blog regarding the testing (EDIT: Sorry about the quality):
I don't have the cover on the timer yet. It came with a black one but I didn't like it so I am making one out of Lexan. Also the wires are sitting on my bench cause I am still working on the aluminium frame that will hold the IR LEDs and Photo Transistors. There are a buch of other pics, process diagrams, drawings, and video of this build at http://jarrodsinclair.wordpress.com/ where I am building a project page with detailed information on the build.
