Some time ago I decided to build a nixie clock. Robert will do the design of the clock. Because he uses AVR microcontrollers I already made an AVR programmer.
For the nixie clock I have made a “high voltage” power supply. This is based on the well known circuit, but I adapted it with an enable input.
(If the enable pin is high the power supply stops, the pin can be left floating without problems)
