Monster Bag

The monster bag "eats" sounds and "spits it back out", both on command and "when it feels like it". Recording and playback are handled by an Arduino and controlled by (1) the magnetic purse snap, (2) position of the wings, (3) the two buttons on the strap. The snap plays recorded sound whenever opened. The wing position records or plays back at a random time, for a random interval. The strap buttons play and record when (stealthily) pressed.

The bag was designed to be practical as a purse. The electronics are (mostly) removable and the speakers and microphone can be stored inside the bag. The bag is fully lined, hiding the interior wires.
