Skannerz Commander: reconstructing the toy's trade protocol

Skannerz Commander trade research reconstructs the electronic toy's three-pin exchange protocol from a 200 kHz logic-analyzer capture and controlled hardware experiments. Its documentation covers clock phases, handshake, frames and monster payload fields; an Arduino slave emulator implements the exchange, which the author reports using in real trades.

Requirements & limits

Prerequisites: A 5 V Arduino Uno or Nano and three wires are needed for the slave emulator; 3.3 V boards need level shifting.
Prerequisites: Reproducing the capture analysis requires Python 3 and numpy.
Limits: The slave-side reject byte and HP zero remain open questions.
