HAKKO 907 24v Soldering Station
I never had a nice soldering station. At best it was an Antex SX25 (great iron but eats up elements) on a variac. It's still not great as this iron costs £4 on fleabay - dont fear, this was just a test. A nice original HAKKO iron is on the way. I prepared by making this PID loop controller for it. I was amazed at how linear the thermistor is. Compensation in the software help accuracy to be ~+/- 2c. It only ramps the duty cycle up past 50% above 400c to help prevent thermal shock.
