A couple of month ago Mr. Longwinters
send me some plasma (NEON) bulbs wit European E-27 windings.Mr Junophor
offered me a big peace of mahagony wood. So I had the basic material for a steampunked binary clock.
The clock is driven by a CControl micro controller and some solid state relais.
A small Basic program reads the internal clock (controlled by a DCF signal), converts the values to binary format and sets the bulbs.
A 5V relay is used to simulate the ticking of a clock.
