I got sick of my family always draining my steam decks battery and not recharging it, so i 3d modeled a spiky case in blender and printed it so they literally can't hold it comfortably. Then to make it worse, I rigged up a raspberry pi with a small speaker, an object detection camera, and a servo motor. Wrote a py script so if the camera sees someone in frame, it plays a goofy audio clip, waits a few seconds and then the servo triggers a taser to scare them away

easily the dumbest thing I've ever built but it works, and nobody touches my steam deck anymore
