In this video I will show you how I created a Variable Laboratory Power Supply from a computer ATX. Don't throw these PSUs away! These can be very useful for any electrical project. The whole power supply is very cheap, no more than 10$. The main unit of the device is a ZK-4KX Buck-Boost converter module, that is adjustable in 0.5-30 V and 0-4 A range. Additionally you will need some basic components only.
