On reflection, I think this will be my first PCB project. I need something small to cut my teeth with KiCAD.

Uses as I said either 1 1/2 volt or 3 volts as 1 or two AA or AAA batteries (comes in two versions). Can you guess? - you may find it at your local thrift store or at a camera show - I buy the whole unit for $1 then take it apart for the high voltage generator. The "guts" are also available from some electronics online sources such as Electronic Goldmine. If you have a small plastic box - either a fancy Hammond box or something from the dollar store it is easy to put together. (It's a single use disposable camera with neon charge indicator !)

I would love to make one, though that isn't what I was asking about! - Paul On Saturday, January 21, 2017 at 10:12:25 AM UTC-5, Paul Andrews wrote: Hi, I received a shipment of tubes (Z5900M) that I want to fire up (becasue, you know, I want to see them glow!). I have a cold cathode tube power supply. Could I use that? DO I need to add a resistor to the anode? Should I get me a power supply of some sort instead? If so what? Very naive when it comes to electronics, but not a complete newb. Thanks - Paul -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
