Overview

• ChromaLock used a Wi-Fi-enabled microcontroller and custom PCB to enable internet access on the TI-84 calculator.
• The project, shared on GitHub, includes features like ChatGPT functionality, a chat window, and a monochrome image viewer.
• The mod required intricate modifications, including voltage tweaks and the addition of 1K resistors between the microcontroller and link port.
• Future updates could expand capabilities to include web browsing, email, video playback, and Discord access.
• Despite its potential as a cheating tool, the complexity of the modifications makes widespread adoption among students unlikely.
