On Saturday, a YouTube creator referred to as “ChromaLock” printed a video detailing how he modified a Texas Devices TI-84 graphing calculator to connect with the Web and entry OpenAI’s ChatGPT, probably enabling college students to cheat on exams. The video, titled “I Made The Final Dishonest Machine,” demonstrates a customized {hardware} modification that enables customers of the graphing calculator to sort in issues despatched to ChatGPT utilizing the keypad and obtain dwell responses on the display screen.
ChromaLock started by exploring the calculator’s hyperlink port, sometimes used for transferring academic packages between units. He then designed a customized circuit board he calls “TI-32” that comes with a tiny Wi-Fi-enabled microcontroller, the Seed Studio ESP32-C3 (which prices about $5), together with different elements to interface with the calculator’s programs.
It is price noting that the TI-32 hack is not a industrial mission. Replicating ChromaLock’s work would contain buying a TI-84 calculator, a Seed Studio ESP32-C3 microcontroller, and numerous digital elements, and fabricating a customized PCB based mostly on ChromaLock’s design, which is out there on-line.
The creator says he encountered a number of engineering challenges throughout improvement, together with voltage incompatibilities and sign integrity points. After growing a number of variations, ChromaLock efficiently put in the customized board into the calculator’s housing with none seen indicators of modifications from the skin.

To accompany the {hardware}, ChromaLock developed customized software program for the microcontroller and the calculator, which is out there open supply on GitHub. The system simulates one other TI-84, permitting individuals to make use of the calculator’s built-in “ship” and “get” instructions to switch recordsdata. This enables a person to simply obtain a launcher program that gives entry to numerous “applets” designed for dishonest.
One of many applets is a ChatGPT interface that is perhaps most helpful for answering brief questions, nevertheless it has a disadvantage in that it is gradual and cumbersome to sort in lengthy alphanumeric questions on the restricted keypad.
Past the ChatGPT interface, the machine gives a number of different dishonest instruments. A picture browser permits customers to entry pre-prepared visible aids saved on the central server. The app browser function allows college students to obtain not solely video games for post-exam leisure but in addition text-based cheat sheets disguised as program supply code. ChromaLock even hinted at a future video discussing a digicam function, although particulars had been sparse within the present demo.
ChromaLock claims his new machine can bypass frequent anti-cheating measures. The launcher program may be downloaded on-demand, avoiding detection if a trainer inspects or clears the calculator’s reminiscence earlier than a check. The modification may supposedly break calculators out of “Check Mode,” a locked-down state used to stop dishonest.
Whereas the video presents the mission as a technical achievement, consulting ChatGPT throughout a check in your calculator virtually definitely represents an moral breach and/or a type of educational dishonesty that might get you in deep trouble at most colleges. So tread rigorously, examine laborious, and keep in mind to eat your Wheaties.
