200V DC High voltage pocket generator
Aki made this DIY pocket HV generator: There are times you find yourself looking for a relatively high voltage (100V to 200V often in my case) but low current DC power supply. I have zener diodes that are higher than 30V, which makes the lab supply useless, and filament LEDs with...
