Hi Everyone,
I got one of the $3 samsung vfd's from elecrow that has nine 7 segment numbers in it. I was able to make it work and figure out its pinout by hooking 2.5V DC across the filament and feeding 12V to the grid and segments.
My question is - what easy, low part count, cheap circuits can be used to generate 12V from 5V. Doesn't need to be much current, I think the 12V was only a few mA while the filament was 100mA.
Also, the filament is supposed to be AC, any ideas for the same, easy, low part count, cheap circuit to make a voltage AC drive for the filament?
Thanks,
Alan
