Fully Automatic Electric Can Crusher #piday #raspberrypi @Raspberry_Pi
This video series from All Thing Eleco-Mechanical on YouTube goes through the details of building a can crusher. Via Hackaday:
At its heart is a 120V AC powered linear actuator, which crushes a can held in a welded steel guide. As the can is crushed it drops into a waiting bin, and when the actuator retracts a fresh can drops down from a hopper. Control is handled by a Raspberry Pi, and there are end sensors for the actuator and an optical sensor for the can hopper. As it stands, once the last can is in place the machine stops due to the optical sensor registering no can in the hopper, but no doubt a software change could cause it to execute a single crush cycle after the last can it detects.
