hackaday.com

Chris Doble built a high-vacuum system controller for his self-made electron microscope. The controller, based on a Raspberry Pi Pico 2 and written in Rust, unifies separate interfaces for a pressure gauge and a turbomolecular pump. It connects via USB to a host computer. This system achieved a vacuum pressure of 10-6 millibar during testing, with the pressure continuing to decrease.
