The control board for the
Arc Reactor was the first custom PC board we built, and it was the first project we did with an ATTiny85. In preparation for Maker Faire 2014 we thought it would be fun to use similar techniques and parts to build possibly the nerdiest watch ever. Here’s what we came up with.
The Nerd Watch displays the time in binary by flashing two LEDs, a green one indicating a binary 1, and a yellow one indicating a binary 0. The video demo shows how it works.
Sam has created a much improved version of the watch using the
Othermill. Check out his
