In the TV show Doctor Who, the protagonist uses a deus ex machina called the 'sonic screwdriver.' I started this project with the intent to make one which contained a TV-B-Gone and a RGB flashlight, then add on as possible. Back as a youngling when starting this, I'd not yet learned to code more than simple C programs for Arduino. At its core is a Arduino Nano knock-off with an RGB LED and an IR LED wrapped in a copper pipe and some fittings from your local big box tool store.
Currently, it sits in a state of disembodiment waiting to be returned to. The main objective would be to clean up the old code and see if that functions correctly before deciding on any other devices to attempt at integrating.
