This Nixie Clock differs from most of similar projects. I found a solution to avoid interference to DCF77 receiver coming from the used High-Voltage switching generator. A two-buttons full functions regulation is supplied on the back rear. The elegance of the wooden-made cabinet contaning the circuit makes it a real to-have fashion design object.
