Here's yet another audible dice tower I built by request for a vision impaired gamer. This one is built using the case and original speaker for a Heathkit HD-16 code oscillator. The HD-16 was available as a kit in the late 60's and early seventies. It was used by HAM radio operators to practice morse code.

This one includes some new features like rotary encoder knobs to select dice count and dice type, exploding dice, and Dungeon Master mode. See the video below to see how it works.
