ROKR 3D Puzzle Classical Gramophone

This laser-cut wooden kit builds a mechanically functional gramophone! You read that correctly, it plays actual records within 10 inches. What a time to be alive! This classical contraption features a 3-phase brushless motor that converts current signals to audio signals that play through the horn, a centrifugal governor that stabilizes playback speed, and three different speed wheels (33/45/78) that can be easily swapped out and stored beneath the gramophone when not in use.
