Pax Instruments Blog Hack Cheap PID Temperature Controllers

It's great how Derryn uses an off-the-shelf PID controller and replaces a single board with his custom design. Because the design of these controllers is modular, with a power supply board, display board and separate microcontroller board, I've designed a new microcontroller board that has the same physical form factor of the old board. I'm [...]The post Hack Cheap PID Temperature Controllers appeared first on Pax Instruments.
