120V Triac Dimmer Circuit - YouTube

Nice little dimmer / SMALL AC motor speed control circuit for 120VAC. 4A MAXIMUM. I made this to be used as a temperature control for my 40W soldering iron. I replaced the triac with a BT136-600, and also replaced the 15K resistor with a 10K. Link here: http://www.aaroncake.net/circuits/dimmer.asp
