Low quiescent/ standby boost regulator 3.3-500V

@jbb Thank you for the effort! I pretty much built it in dcm without realizing it was an actual thing. I guess Really going in and calculating times and frequencies would only be reasonable if power output was relevant. Since i almost dont care how long it takes to charge i can just go for maximum turn off time.

Voltage division is always a thing of concern to me, though in this case the currents are so low and there is no large changes the internal resistance is enough to even the voltages across all parts. Though I will try to use diodes rated at the full capacitor voltage next time i order some, even if they will survive any ways, higher voltage rating also means lower leak.

@Miti Allways nice to see other ones for reference! The first geigers i built were actually very similar to this one minus the readout part. is it actually a string of zeners for voltage measurement next to the multiplier?

@profdc9 Sadly thats just high power and very low efficiency, im looking for pretty much the opposite :D But yes, you can actually use those for a simple geiger, if you replace the cap with a low leak one you may even get long battery life just charging it from time to time. The nes i know even run of a single 1.5V cell, also something i really like.
