Aniket95-code/Fan-Speed-Controller-NE555-PCB-design
A simple, low-cost DC fan speed controller built around the classic NE555 timer IC operating in astable mode. Fan speed is adjusted by varying the PWM duty cycle via a potentiometer, while a TIP122 Darlington transistor…
18 parts, built around the TIP122. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the NerdST/Filtration-Device repository on GitHub, at the commit this page was made from: the board is Valve-Control/Valve-Control.kicad_pcb and its schematic Valve-Control/Solenoid_Control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask NerdST before reusing the design.
