Yeah, I'm looking for a crossfire and hand torch myself. As the neon business in the United States is not doing well, I'm hoping I can buy used ones (and hopefully a blower) from a shop that's downsizing. > The heaters from Neon John are quite beyond my budget, sadly, but I guess > this is really something that could help me a lot. That's why I mentioned that the design is open source, so you can roll your own and save money. I'll also list some sites where people show their own simple induction heater designs - some of these are just a handful of simple parts. http://webpages.charter.net/dawill/tmoranwms/Elec_IndHeat1.html For this one, you really only need to a few parts, a high current high frequency capacitor (Digikey PF2105, less than a dollar), and a heavy duty 2SC3519 transistor (less than five dollars) and wind a couple of very simple coils. http://scopeboy.com/elec/induction/index.html http://www.richieburnett.co.uk/indheat.html http://www.abiscus.com/highvoltage/IndHeat/IndHeater.htm > I already built a two-terminal glass-feedthrough in a 8mm tube, the next aim > is to turn it into a primitive glow lamp...

Watching the arc form and change character as the pressure drops is very interesting and instructive. If you measure the voltage and current, you can watch the Paaschen curve happen too. Just run it on rarefied air to start with, you can play with adding Ne/Ar later. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
