Topic: How to make a small heater element (Read 18585 times) previous topic - next topic


just find the cheapest 12V DC solder iron you can find that is rated 15W and use it with a transistor and a 12V DC powersupply and pwm pin on the arduino
You can use PID (PID arduino library) to get a great control of the temperature, if Solder iron is too big, just buy 12V cigarette lighter for a car (spare ones are not hard to find) and solder leads to the right places. (the handle is al least not hard to fix to some sort of a surface)

This is probably the easyest solutions, short of buying the heating element itself (nicrome wire, sold at electonic components shop) and make a small coil of a heater)
