Hakko FX-888 soldering iron pilot light

The Smell of Molten Projects in the Morning blog writes about fixing a Hakko FX-888 soldering iron”

The Hakko FX-888 soldering iron perched on the corner of my bench has a little red LED that lights up when it’s heating and goes off when it’s not. Unfortunately, while shutting down after fixing something, I sometimes glance at the thing while the LED is off, whereupon it will patiently keep the iron hot, sometimes for days, until I return.

A recent Squidwrench session gave me the opportunity to yoink that nuisance off the to-do pile where it has been pending since about ten minutes after I unboxed the iron a decade ago.

See how it’s done on the blog post here.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
