Sleep Drone 5

I like this case, I do admit. Sleek metal box with knobs galore and opto sensors. Nice paint job and the rivets are kind of cool. Judging from the the inside shots, its seems to me that the builder is only using one IC, along with some caps and resistors. This may lead me to believe that the circuit is similar Schmitt Trigger idea that I have utilized in the Gameboy build. BTW, the schematic for that will be released in time for X-Mas. Currently the SleepDrone 5 is up on eBay, however more instrument can be learned here:
