[Faransky] has created a very impressive Arduino function ... important in a function generator. So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer as a voltage divider on the ...

It’s an easy to build high voltage power supply ... that can be easily controlled by an Arduino to something that will arc an inch and a half. The next step building the flyback driver.

Learn how to create a high voltage generator using a flyback transformer’s ferrite core. This step-by-step process involves assembling a circuit with MOSFET z44, tip122, or D880 to boost voltage ...
