Hi, First of all *jrehwin* - thank you for a very detailed answer, it is great to know that there are such a great communities in the Internet.
I've just resolved my problem thanks to you guys. So what I've done: - changed the resistor to 47k - set HV source to ~170V - add normal diode in 5V line. I think that my problem was caused by few things at once, but I think the main was how I set voltage sources. Because of lack of good, stabilized voltage source I have something like this: - From AC 230V i have 12V DC power supply (Made in China, so I realized that this is actually 18,7V ) - I connect it to my breadboard and than branch it to 7805 and 7809 stabilizer (with capacitors ofc) - Output from 7805 goes to logic - Output from 7809 goes to mentioned voltage converter and becomes 170V which is my HV line Thank you very much for all ideas and help. Today I will make an upper board for Nixie Clock (tubes+ TLP627 optocouplers for multiplexing) and start to develop logic board (I'm going to use ATtiny2313+PCF8583+74141). As an alarm sound I will use old-school electric doorbell with metal chime.
