I should take the time to put it on the web. My degree is in electrical engineering and so I went all out and designed the pcb and all the goodies from scratch. It also has an integrated capacitive touch screen that I integrated into the PCB so that I can change modes by simply pressing on part of the screen. I think it would make for a pretty sweet open source project since the display could be pretty universal and the wireless sensor could monitor lots of things beside temperature. It would make for a wicked seismograph project....
