Beautiful, "lethal" freeformed Nixie tube clock
Having seen and admired Matseng's freeformed "The Lethal Nixie Cube Clock," which displays the time one digit at a time, I have only one question: is this a great-looking Nixie tube clock, or the greatest-looking Nixie tube clock:
It's a clock made of a single IN-1 Nixie tube controlled by a ATMega8. The Mega8 directly controls 10 pcs of MPSA42 high voltage transistors for lighting up the filaments in in Nixie. It also generates the high voltage required for the tubes by a pwm output connected to a IRF520 N-FET and the usual inductor and fast recovery diode.
