Hello everyone! I'm doing project for college and I've decided to make an audio visualiser using IN-9's. The problem is I don't have any idea how to power them. I'd like to have 18 tubes for different sound frequenties and I'll be using stm34 to calculate the value each tube should show..
Now, I know I need 140v and 0 - ~~12 mA for 1 tube but that's all I know honestly. I think I'll use something like the 0-offset driver found in HERE <https://www.die-wuestens.de/rd/IN9-2.pdf> controled by PWM of my uC but I honestly have no idea how to power them. Is 140V(or 150V? everywhere except there it says 140V) enough even for 18 tubes? If yes is it possible to make this kind of supply myself as I can't find anything reasonable price-wise with 140V. Do I need to consider anything else? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
