Automated can crusher, built using all scavenged and repurposed parts, except for the wire terminals and a couple microswitches. The lcd display, electronic components, and case are salvaged or recovered and repurposed from unrelated machinery, and even the Raspberry Pi is being reused from a previous project!

Controller is a Raspberry Pi 4.
Crusher is a salvaged 12V linear actuator generating 1000N of force at peak.
A pair of optocoupler relays form an H-bridge switch to allow the Pi to control the higher voltage and amps.
All sensing is done with microswitches.
Programming done with python3, using gpiozero libraries.

This took a lot of finnicky drilling and adjustment to get to work smoothly.
