Fan controller
1 minute read

Yay, I finally made the amplification step for my software-controlled fan controller project. It was fairly easy, it’s just a non-biased normal transistor circuit with a protection diode (as I’m controlling fans, which have motors) and a “brake” resistor on the base of the transistor.

I do really need to fix my soldering skills, I’m totally out of date and having trouble with the iron.

The next step is programming a micro-controller to do pulse width modulation and then hook it up to the fan. From there, it’ll just be fun and easy. I also need to make a bunch of those.
