Hi Fooeywuffle

I guess it's because I can make the PCB and stuff the parts on one of these ( http://www.ledsales.com.au/kits/nixie_supply.pdf ) for less than half the cost and in far less time, But I guess I also have never made a transformer

Keep us posted on your progress

I have made a lot of switching power supplies from a few watts to 1200 watts, but I use the ICs made for that. Like Linear Technology Lt1172 for small loads and their more powerful ones if more current needed. National Semiconductor also makes a lot of them, Simple Switcher. They are cheap, and very easy to use, and have better regulation than these 555 timer ones, but they work the best if used with a flyback gapped core transformer to keep the waveform close to a square wave at operating voltage. I guess these must work since they are all over the web. For my clock, I was keeping everything old school, so no ICs allowed. I have been winding transformers for over 50 years, from audio to over 100 MHz.

Clock is FINALLY finished! Uses GE 3N83s and a few transistors, no ICs. Nixies are IN-12A.

That is very cool. Do you have a schematic?

Cheers Matt.
