For this project I was wanting to build a clock. (Obviosly) When deciding on a theme, I thought about the countdown timer that is rather prominently in Neon Genesis Evangelion. The Eva normally uses an external umbilical for power, but can run from internal power for a limited time. When the umbilical is disconnected, the timer is activated.

This timer only has positions for a single minute, 2 seconds, and deci- and centiseconds. This meant I had to extend and shift positions for normal time telling.
