George 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 when the user leaves it turned on too long (Like Jeremy himself did with a Hakko FX-888 for 2 weeks!).

George and Jeremy sit down with Beric Dunn (K6BEZ), the designer of the project, to introduce the Arduino powered DDS module based Antenna Analyzer! Beric is a professional RF design engineer by trade, and he wanted to provide a project that would allow a ham to learn some fundamental principles while making a useful gadget.
