Cracking the Furby code: The path to evolve an icon
summary
1998 Furby sold ~40 million units; reverse engineering digs up a 197‑page 6502 assembly leak, a shipped bug that makes Furbies “sick,” and activation sequences for twinkle twinkle and Simon Says. Random seed comes from boot sensor noise, one motor drives cam‑stacked linkages that encode multiple expressions. Built retrofits and a cable‑actuated remake using Teensy, Pulu Maistro and an MP3 trigger with 3D‑printed parts; prototypes work and demonstrate much richer, low‑latency expressive control.
