Found a small fan in two parts that breaks into two ~40mm 6v fans. Thinking about using it/them for cooling my #raspberrypi. It seems that it also has a third pin for speed control, which I need a motor controller for.
Might design a PCB motor driver HAT for it as a good starter project with #KiCad / #SMD assembly, All I really need is a few motor controller IC's...I think. We'll have to see how this project goes.
In the meantime I might just order one of the 30mm raspi fans off of ebay for $5 while I design it, as the pi does seem to run a bit hot with a DE.
