The clock ring is an exercise in low power electronics as well as designing under extreme space restrictions. The ring consists of a flexible PCB, populated with LEDs forming a 7-segment based display. The time is maintained by a microcontoller and the user activates the display with a gesture captured by an extremely low power accelerator. The current design uses replaceable batteries and has a run time of around 5 months. The upcoming version will be solar powered, thus reducing the space required for batteries and allowing the ring to be used indefinitely.
