Modder hacks ChatGPT, other apps onto TI-84 calculator, creates 'The Ultimate Cheating Device'

An extensive hardware modification, but the stealthy integration works well.

Watch On Besides software modification, the hardware needed to truly complete this "ultimate cheating device" was a microcontroller small enough to fit inside the TI-84 shell with its original components. A correctly selected Wi-Fi-enabled microcontroller, in this case, the Seeed Studio XIAO-ESP32-C3, modded into the calculator with the TI-32 PCB and suite of software installed is all you really need to get up and running. In the full video, ChromaLock demonstrates exactly that functionality after tweaking voltages and adding his own 1K resistors between the microcontroller and link port appropriately.
