I need to throw together a circuit which uses a pot and triac to provide adjustable control of a heating element rated at 150W 240V AC. Does anybody know where to find a suitable circuit? Would an ordinary light-dimmer circuit be appropriate or not? http://www.electronics-project-design.com/Light-Dimmer-Circuit.html Will this circuit do the job? If i use this circuit, can I remove R2 and R3, change the pot to 47K (or 100K ?), use a BT137 triac, and change C1 to 100nF? Is the inductor really needed? Can I get rid of it? Cheers.
