I was recently looking into Nixie tubes however the requirement of high voltages was a bit scary, especially given that these voltages were in the 150-200V range.
Instead of using a boost converter with a low voltage supply like the 5v rail on an Arduino, I decided (for the sake of simplicity) to simply do what most cheap LED torches do - Put 50 or so CR2032 batteries in a plastic tube with wires on each end. This way I can get a voltage of 150V or so easily without any boost circuitry. The problem, however is that I have absolutely no experience doing so, nor have I ever heard of someone doing this with more than 6 cells before.. Will the batteries do something bad?
Also, would I be able to power a Nixie like the IN-14 with a setup like this?
