This video will show you how to make a small yet functional lab bench power supply, with the added feature of being able to power it from any DC power source anywhere between 3 and 50V. Warning: Working with 110V or 220V is extremely dangerous without proper knowledge. Please consult a professional if unsure. I am not responsible for injuries or damages caused by this power supply during build or use.
