It’s not entirely clear why [Advanced Tinkering] needs a 50,000-volt power supply, but given the amount ... To ensure everything stays safe in the high-voltage stage, he took the precaution ...
The variable power supply they plug into ... The project nearly became Fail of the Week fodder after [td0g] saw huge voltage spikes across the MOSFET. A 47kΩ resistor took care of those ...
