Simple Arduino experiments with nixie

Kevin is collecting parts for his nixie clock project. But before starting he played couple experiments on starting and controlling IN-12s and In-3s nixie indicators.


In order to start IN-3s there is 90 volts needed. He had 170V step-up converter board, so he added 68k resistor in series to get to required level. Next step was to connect to Arduino. For this purpose he used MJE340 power transistors. After this successful experiment he will head straight to clock project.
