Hi,
I see quite a few soldering irons for sale for maybe 25 dollars USD and they have three to four wires. I am guessing that the three wire ones are two for resistive element and one for temperature probe, and not sure what the four wire ones have but im sure it's not too difficult.
Question is, how hard can it be to make a controller for these things? I would think simple, with a controllable 24vdc supply for example. They are about 60 watts so figure about 3 amps.
Seems a simple controller with pass transistor, op amp, amplifier to amplify the probe signal.
No need for an LED display for the temperature.
Has anyone tried this yet?
