Cotton Candy Vending Machine Hacked to Enable Full Control

A used cotton‑candy vending machine purchased for $300 was left without manufacturer support for remote account access. The owner, operating under the name Block’s Retro Repairs, accessed the device’s Android‑based control system via a terminal and extracted the product database. After several attempts that included a factory reset, the machine’s performance improved and it began reliably producing candy.

Using free large‑language‑model coding chat‑bots, the owner modified the original Chinese‑language app to add a custom settings menu, allowing local price adjustments and eliminating the need for online access. The machine was also sealed against further intrusion, completing the conversion of the vending unit into a fully controllable private arcade attraction.
