Just before he silently stole away on a secretive mission to distant lands, Ranjit left a hoard of lovely obsolete electronics at the lab. Among the treasures were a couple of old counting units with 7-segment incandescent displays, sometimes called numitrons. I’ve turned this one into a simple clock.
Thanks to Charles for the spare pushbuttons, Ranjit for the original unit, and Evil Mad Scientist for the protoboard.
