I should like to build a circuit so I can regulate the heat in my heated clothes.
I should use a jacket and gloves winthertime in my autogyro.
jacket and gloves draw 10A and battery is 12v.
Are there any components you can fins in an old PC?

 

The only useful thing in an old PC is its power supply which is not very powerful to power your application. However, you can use it for other circuits.

 

There have been many PWM circuits published in AAC over the last few months. $ 15 should cover it.
