Inspired by Matt Dyson's Raspberry Shake and hackaday (twice) I decided to build something like that myself. I liked the idea of monitoring my washing machine, but of course I had to make it different, just to enjoy the creative process.
I attached two MPU-6050 sensors to an Raspberry Pi, so I could monitor both the washing machine and the dryer at the same time. I built both sensors in a seperate box, and connected them with a CAT5 cable. The Raspberry Pi monitors the two sensors and notifies when the vibration starts or stops.
I went and bought some RGB-led's , because I could.
