Display PC CPU and memory load with analogue meters
From "The mad science of an insane ginger" blog comes a simple project of interest to the PC performance enthusiasts. Using an Arduino and two analogue panel meters, the CPU load and memory usage can be displayed using information sent from a python script running on the PC. Analogue panel meters can be driven quite easily using pulse-width modulation and this is also the case in this project. And by making your own background images for the meters and a nice housing, you can turn this into a professional project.
