Default Re: Powering a HeNe with an old CRT monitor

I suppose there would be some way to regulate the output. HIMNL9 could probably lay out a circuit to do it in 5 minutes. It would take Me a bit longer. LOL

Why reinvent the wheel? There are already lots of circuits, and many of the parts you need to build something similar can probably be salvaged from the same old monitor or TV.

I know I just like taking HIMNL9s name in Vain...

I knew schematics were out there, but forgot Sam had them as well...Good Call. +Rep.

Hak You could use a flyback for the tube you have with no PS.
thanks for remembering that I needed help--+rep to you sir!

Hmmm. Thanks james1095, I will heed your advice. I don't wanna accidentally destroy any of my HeNe tubes. It is indeed some intense ionizing voltage and it wouldn't take much to zzzzap one of 'em. I think I'll just stick to the brick PS. :lol
