fan controller

This is likely the first ham radio related project that I document here on this blog. But my very first PIC project was a beacon keyer that I made for my father, HB9BBD. That was was in 2013. A beacon keyer is a great project to get started with microcontrollers since it’s not much more than a fancy way of blinking an LED.

I’m currently mainly working on my new anemometer design but once in a while I get distracted. For example when my Keysight E3645A lab power supply was making so much noise that I could hardly concentrate. That’s when the idea of this fan controller was born.
