abstract: |
  Speedsolving, the art of solving twisty puzzles like the Rubik's Cube
  as fast as possible, has recently benefitted from the arrival of
  smartcubes which have special hardware for tracking the cube's face
  turns and transmitting them via Bluetooth. However, due to their
  embedded electronics, existing smartcubes cannot be used in
  competition, reducing their utility in personal speedcubing practice.

  This thesis proposes a sound-based design for tracking the face turns
  of a standard, non-smart speedcube consisting of an audio processing
  receiver in software and a small physical speaker configured as a
  transmitter. Special attention has been given to ensuring that
  installing the transmitter requires only a reversible centercap
  replacement on the original cube. This allows the cube to benefit from
  smartcube features during practice, while still maintaining compliance
  with competition regulations.

  Within a controlled test environment, the software receiver perfectly
  detected a variety of transmitted move sequences. Furthermore, all
  components required for the physical transmitter were demonstrated to
  fit within the centercap of a Gans 356 speedcube.
