Diode based Fan Controller
Diodes can be used for temperature sensing. Nick Chernyy used this principle to make a Diode based Fan Controller for his Shuttle PC. “Figuring that I should just go build a more substantial fan controller myself, I promptly went to the lab to look for a thermistor. Unable to find one, I settled for the next best thing: a diode. After building the circuit, I tested the output with a
