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

Just a guess, but I think by lighting them all up you get some kind of “super ionization” in the tube, which could then increase the current and heat dissipation. Bill From: neonixie-l@googlegroups.com [mailto:neonixie-l@googlegroups.com] On Behalf Of Yohan Park Sent: Wednesday, March
