Anyone interested in playing with PIC devices may want to take a look at the Microchip AppNote TB053. It describes (in great detail) how to use a PIC16C781 for a boost converter producing a regulated 170V at about 2W from 9V DC. It is a fairly simple solution which is easily ported to other PICs, and with some more effort to other brand MPUs. The beauty is that if you have spare resources in your device MPU, you can add this functionality right in.

If you want a quick solution, there are a LOT of simple, cheap DC supplies covering this range on ebay: e.g. https://www.ebay.ca/itm/High-voltage-power-supply-module-kit-DIY-for-Nixie-tubes/261169220982 at < US $8 each --Toby > divider resistors ) to get 170V at 2.5mA, that should be enough > current for one 1N16. > If you need more current, have a look at the LT3757 in flyback mode. > > -- > You received this message because you are subscribed to the Google > Groups "neonixie-l" group. > To unsubscribe from this group and stop receiving emails from it, send > an email to [email protected] > <mailto:[email protected]>. > To view this discussion on the web, visit > https://groups.google.com/d/msgid/neonixie-l/41554687-014e-4f4b-bc08-1 > f46f7b6812c%40googlegroups.com > <https://groups.google.com/d/msgid/neonixie-l/41554687-014e-4f4b-bc08-1f46f7b6812c%40googlegroups.com?utm_medium=email&utm_source=footer>. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
