Daniel build this clock after having to chose from a watching a movie or working on a project. Obviously he and hi’s friend chose to make the clock so it wassn’t long until the LED’s started to light up. The clock code is based on the open-source-arduino-clock by Rob Faludi. Daniel made many changes, but the time counting the basically the same. So if you want to make another kind of clock, I suggest you to take a look on that code.

Probably the most exiting feature is POV mode what means “Persistence-Of-Vision” – time is displayed when swiped in the air. POV mode uses only 5 LEDs aligned in a single row. Clock is made of PIC16LF628A microcontroller that controls super-bright LEDs. Watch is powered from 70mAh lithium-ion polymer battery that can be charged from USB via MAX1555 Li-ion charging IC.
