Lm317 fan 36v
kbralten/lm317-fan-speed-controller
This project is a robust, solid-state analog fan speed controller I designed to regulate fan speed based on temperature.
13 partsCERN-OHL-W-2.0
Boards in 1 GitHub repository, designed in KiCad, that use the MPSA27 by onsemi (-55℃~+150℃@(Tj) 1.5V 10000 10V 125MHz 2V 500mA 500nA 60V 625mW NPN TO-92(TO-226) Darlington Transistors ROHS). See how each wires it, with its parts, size, README and files; the MPSA27’s symbol, footprint and pinout are on its own page.
