Ham Radio: Workbench 9 – Designing an Idiot Switch

A lesson in design thinking, collaboration, and learning to admit when you are wrong…

This week on the Workbench, George KJ6VU and Jeremy KF7IJZ are joined by Beric Dunn K6BEZ and Nick Garner N3WG to design an “idiot switch” – a micro controller device that can remove power from a soldering iron in case when the user leaves it turned on too long (Like Jeremy himself did with a Hakko FX-888).  Join the gang in this episode to hear different approaches for solution design, implementation approach, and the ultimate consensus at the end.

  1. Jeremy, I meant to send this note a couple of episodes ago, but I will now anyway. I purchased the Weller soldering station model WESD51 and have been very happy with it. I too tend to leave the bench after a session forgetting to turn it off. But I was pleasantly surprised after I did this the first time to discover that it turned itself off after a period of disuse! I’m not sure what the time period is, or if I can alter it, but it’s on the order of 20 – 30 minutes, certainly less than 1 hour.

    I know you’re looking to acquire a Hakko station, but let me recommend this Weller product for your consideration.
