Fan control
-
Hello all!
This topic has already been discussed few times as i saw but I didn’t find info to achieve what i want. Maybe someone is also looking for a similar solution with some electronic skills and we can work together to find the “perfect” solution :p (a relay based solution is omitted on purpose).The idea is to have a circuit to control 2 fans (12v - 0.33A) with either a mosfet or a bjt with a good schematic that will protect the Pi with some pull-down resistor, diodes, etc and finally cool down the whole mirror when the temp threshold is reached.
If anyone is interested to have such a system and gain knowledge at the same time in electronic, feel free to share ideas.
First objective would be to determine which type of transistor would be the best: mosfet or bipolar and why?

or just a 12v supply with a relay that reacts to the 3v/5v output of the raspberrys gpio …
or just a relay if you already have the 12v supply.

@broberg thx for your input. As mentioned above, i wanted to avoid using a relay to have a silent system

@bibi fan controllers are cheap.
or get 5v fans?
-
@broberg have already a 5v fan… i am rather interested in gaining knowledge about transistors by building a “project” to cool down my whole MM system.
