Though slightly off-topic, I had a bad experience (as in smoke, sparks, and explosion) with a microcontroller-based DC-AC inverter many years ago. It was a tad bigger than a nixie-supply because the DC supplies (+170 VDC, and -170VDC) each had 10,000uF of filtering; almost 300 joules of energy.
The microcontroller crashed, and that caused the HV transistor-stack between -170 and +170V to short-out. Pretty hefty transistors, too. (rated at 50amps / 600V). They are bolted-down, not soldered. Lesson-learned: Add protection circuitry to prevent unexpected or "impossible" events from happening, because they do happen. At a minimum, I'd place a fuse between the DC supply and the inductor, and size it as small as possible. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
