I've been running some SPICE simulations on potential candidates for the HV supply, and I'm close to having something I can run from my function generator. I've done enough basic testing on one display with sinusoidal and triangular waveforms running thru a power transformer to confirm the display works. I'll put this onto a small PCB and hopefully test it out in the next few months. I'm aiming for operating around 1Khz, and the iron-core power transformer I'm using right now seems fine up to around 5Khz before it starts to poop-out.
I havn't finalized how to drive the individual segments; most likely I will use small triacs. I've used opto-triacs many times before, so I'll probably stick with them unless I find "regular" triacs for a lot cheaper. My only concern is the leakage current of the triacs might cause the segments to glow, as they only need a few uA. That's another experiment I need to do after I have the power supply nailed down.
