Description
It's a box! But it's no ordinary box - it's a drum box.
It's collaborative, like a drum circle, portable, and customizable (i.e. you can upload any beat that you want to map to a drum pad and change it around at will).
Components
A large purple tub (not quite a box - but box sounded better than tub), 4 red leds, 4 fsrs, 4 cardboard circles, bubble wrap, breadboard, resistors, and a lot of wire
