Re: [neonixie-l] my version of nixie tube testing device...

[Paul Andrews]

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

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 !)

Hi Phil,

Is your tester anything like this one
? I would love
to make one, though that isn't what I was asking about!

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

[neonixie-l] my version of nixie tube testing device...
