Great project!
Have you had any success building a power supply with the CJ5143? I 
completely failed trying to build a 15x15mm PSU with this transformer. I 
have got the 170V but only about 4mA and it wasn't really stable. But to be 
honest, I haven't tried to improve it at all.

Re: [neonixie-l] NIMO

[gregebert]

Jorg - Regarding the dead tube, have you compared the filament resistance 
of the bad tube to the others ?

NIMO tubes have 2 parallel filaments, so if one is open, the resistance 
will be TWICE the value of a good tube.
I think the cold resistance is around 3 ohms.

If 1 filament is out, you can still get 5 numerals to work.

I would be surprised if both filaments are burned-out, unless someone put 
way too much voltage on it, or the tube is cracked around the pins.

If the filaments are OK, power-up the tube and make sure you get around 
180mA of current.
Then try varying the voltage between the filament and the logic driving the 
grids. If a grid is about 6 V more positive than the filament, you should 
get a numeral to turn on.

[Aiden Fang]

Michail,

Great to see you here. Thank you for your continued support. 

The tubeless idea is interesting, and we haven't given it a good thought 
yet. We'll try to see whether we can come up with something in the near 
future.

Thanks for your compliment to our video ;) Cannot wait to make more.

Best,
Aiden
