I’m pretty proud of this project; the clasp is a ribbon cable that doubles as the programming interface for the PIC microcontroller that drives everything. The time is displayed with superbright LEDs that are blinding at 15 mA, which means that I’m able to limit the power consumption considerably while still achieving a very readable display. The watch is powered by the (ever so common and useful) CR2032 lithium coin cell, which gives it an estimated battery life of 3 months depending on usage patterns (still doing research and testing on the average for this… 2 months in and I’m still running on my first battery : )
