I need to control a simple heating element which will run off 12Vdc. It does
not need to get very hot.
I need to make it variable. At the moment I have a 555 running in astable
mode pulsing two MJ13005 transistors which are directly connected to the
element. The transistors seem to get too hot. What other methods can I use?
My element usualy are a bunch of fine stranded copper wires and the one I am
currently using has a resistance of 5ohms.
