In the first video i will be using an old Computer power supply from an old CPU to produce 3.7v, 5v, 12v, 24v DC for running different electrical and electronics appliances. In the second video i will be using some old laptop batteries and a BMS to make a 12V battery pack which i will use to run a 3D printed water pump. In the last video i will be using an old transformer from a dead CD player to make a variable power supply.
