Скачать или смотреть Amazing adjustable power supply? (3-24V 3A)

A small but powerful switching power supply with an adjustable output voltage. It can be set from 3V to 24V DC using a potentiometer, it can handle up to 3A of load current. It might look very promising, but don't be fooled! It has some very serious problems! EMI interference, overheating, risk of fire and electric shock, unstable and thermally drifting output voltage... A thorough test, analysis, what's inside and a reverse engineered schematic.
