There i use only 12V 400mA so sparks are small. Imagine if i would use powerful power supply like in this video https://www.youtube.com/watch?v=NrVMJ84Afg4 . In this video sparks are about 6cm so if i put capacitor to it it can get to maybe 7-8cm (if capacitor won't break due to to high voltage). There i used my homemade flyback driver with one transistor and 2 resistors. If you like this video then Subscribe and support me on patreon! https://www.patreon.com/TestasTChannel
