Bluetooth Speaker in a Walnut

You can buy very small Bluetooth speakers already, but we’ve never seen one embedded inside a walnut. Penguin DIY nibbled on the nutmeat inside before outfitting the shell with a tiny amplifier and Bluetooth circuits, a minuscule speaker, and a rechargeable battery. We worried he would crack it while drilling holes, but the shell remained intact.
