Hi, I've been beavering away on a nixie tube power supply using an off-the-shelf flyback transformer (I wanted to be able to use it in battery powered clocks, but be able to use the same basic design in larger clocks with a 12V supply). I've written the whole process up on hackaday.io <https://hackaday.io/project/27899-nixie-tube-power-supply> if you are interested. It works fine. It isn't in the same league as (for example) the John Taylor power supply, but it is small, produces enough power for most purposes (easily producing 20mA/200V with 12V in for example) and is pretty feature rich - you can enable/disable it and vary the output voltage from 0V to 200V either with a resistor or a PWM signal.
My intention was really to have a design that I could integrate directly into a clock PCB, rather than it be a standalone module, and one that I could tailor to specific clocks - so for example I have a smaller version that uses a smaller 1:20 transformer that works fine for four tubes being driven from a LiPo or USB - but I *have* actually produced some boards over at OSHPark. I hope you all don't think it is *too *bad an effort - I am no electrical engineer - and if you are so inclined, feel free to use the design however you like. - Paul -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
