Ok, I can understand that. You could try a royer converter. The fun is in the making of the small transformer. http://en.wikipedia.org/wiki/File:Royer_Circuit1.gif But there are many ways to skin a cat Cheers! Frank

However, I am busy to make a dc - ac converter. I need it for an other project, where is no hv in use (meter clock). I want to use neon's to avoid LED's because of "old style". Later more. eric -------------------------------------------------------------------------------- From: [email protected] [mailto:[email protected]] On Behalf Of Frank Bemelman Sent: zondag 2 maart 2014 10:59 To: [email protected] Subject: Re: [neonixie-l] IN-3 Neon Bulbs Hi Eric, That’s a good point. I guess it would not be too hard to construct a H-bridge from 2x mpsa42 and 2x mpsa92 and drive that from the microprocessor, or even with one side using mpsa42 and mpsa92 and the other side just 2 resistors of ~100k between HV and GND. Cheers, Frank From: Tidak Ada Sent: Saturday, March 01, 2014 9:59 PM To: [email protected] Subject: RE: [neonixie-l] IN-3 Neon Bulbs I am just occupied to develop a ac driver to supply neon bulbs symmetrical. Those simple neon's with only two rods as electrode are awful on dc. eric -------------------------------------------------------------------------------- From: [email protected] [mailto:[email protected]] On Behalf Of Spencer Sent: zaterdag 1 maart 2014 14:18 To: [email protected] Subject: [neonixie-l] IN-3 Neon Bulbs Hello All! I bought these for the nixie clocks, http://www.ebay.com/itm/251373901401, and they will work for a bit then start flickering all over in the tube, and lighting up in odd places and not where it should be lighting up! An example can be found at, http://imgur.com/O32rVBi . Only the left side is light up, the little light has a mind of its own and has traveled to the back of the tube. I am feeding the little guy +180V and the anode resistor is 220K. I am not sure if its too much current or what not. Several have done this to me. Suggestions?
