In early February, a correspondent pointed me to Jeff Keyzer’s mightyOhm blog. I immediately ran across his homebrew PID-controlled soldering hotplate and improvements, and immediately knew I had to have one.
I contacted Jeff through his blog and he was great about sharing his knowledge. He’d built his hotplate using the last of some surplus parts he’d picked up at a now-closed store in the Valley and was considering ordering a batch of parts to make a few for all the folks inquiring about them, but hadn’t done so yet. I was eager, decided it’d be quicker to make my own (and three months later, that may actually have been correct), and went off to eBay to find myself some parts.
