Neon Iodine Tube
A video showing a small pyrex tube filled with 400 torr of neon gas with a small crystal of iodine. The tube was pumped out for about five minutes to help get rid of residual oxygen and water.
I've been experimenting with these tubes in hopes of making larger displays. The power supply in this case is a flyback transformer driven push/pull with two MOSFETs. The flyback has two resonance points, one at 23kHz the other at 70kHz. the voltage output really goes up at these two frequencies.
I'm still trying to figure out if this supply will be useful. But it is fun.
Cheers.
