Hi sfrwmaker,I built the circuit on a breadboard using the instructable "Soldering Iron Controller for Hakko 907" that you suggested. It works great, thank you. I used the schematic for the thermocouple soldering iron. The full schematic for the thermocouple shows a 10k resistor from 5v to pin 3 of the AD822. This 10k resistor needs to be removed for the thermocouple soldering iron. Otherwise, the LCD shows no iron. Thanks again for a great controller!
Thank you. I appreciate your time.
Thanks,Yes, I should have given more detail. I was saying hakko 907 soldering irons. These irons use thermocouples for temp sense.Do I need to modify the sketch for using these hakko 907 irons? I'll admitt, I'm not to sharp in rewriting code. :)
Yes, I'm 100% sure they are using thermocouples in my version of the irons. It doesn't matter which mosfets I use. I do have n-channel mosfets.The irons has 5 wires. +temp, -temp, GND, 24+(heater), 24-(heater).Thanks
Hello sfrwmaker,I have a couple of questions.1. Can a regular hakko soldering iron (non-T12) work with this project? I have two of these irons laying around.2. You mention of using isolated power supplies. Could a switching supply 24v/5v all-in-one power supply work? I have this one of these .
