Problems with Arduino UNO Nixie kit - high voltage

There's no problem with that, other than usually it is not necessary. If it's going to make the project enjoyable for you, that's going to work for me as well.

I just wanted to check a few other things:
  1. You are using an Arduino UNO, (and not a Leonardo or anything).
  2. Does any component get hot?
  3. Where are you plugging the power in? Into the board or into the Arduino?
  4. Is there any noise coming from anything?

I'm sorry, didn't know what the best option is. First, to answer your questions:

1. It's an UNO. Actually, I tried two Arduino's. An original and a clone. With both no HV.
2. Not really.
3. I'm plugging the power into the board.
4. There's no noice.

I'm afraid these are not the answers you were looking for?

It's just that I'm not capable myself to troubleshoot because I know little to nothing about electronics. But, I am curious and if it's possible for me to test some of the components I would be glad to do so. I own two things: a soldering iron and a multimeter :) don't know if that's enough.

If you read DC volts between the 170V and GND test points what do you get? Is it really near zero, or is it more like 9 - 10 volts?

Look into it later when the dust is clearing off the crater.

It's about the input voltage 11.75 volts

Well that suggests that the inductor and the diode are okay. I suspect the MOSFET is bad. If it is bad I'd expect you to read something like this:

Pin 1 to ground - 1 or 2 volts DC
Pin 2 to ground - 11.75 volts DC
Pin 3 - should have continuity to ground

If you get significantly different readings then maybe the problem is something other than the MOSFET. Please post your readings.

Hi, thank you for the response. Here are my readings:

Pin 1: 3.06 volts for the most time (3.05 to 3.09)
Pin 2: 12.13 volts (170v to ground still 11.75)
Pin 3: has continuity to ground
