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, doubtlessly enabling college students to cheat on exams. The video, titled “I Made The Final Dishonest System,” demonstrates a customized {hardware} modification that permits customers of the graphing calculator to kind in issues despatched to ChatGPT utilizing the keypad and obtain stay responses on the display screen.
ChromaLock started by exploring the calculator’s hyperlink port, sometimes used for transferring instructional applications between units. He then designed a customized circuit board he calls “TI-32” that includes a tiny Wi-Fi-enabled microcontroller, the Seed Studio ESP32-C3 (which prices about $5), together with different parts to interface with the calculator’s techniques.
It is price noting that the TI-32 hack is not a business mission. Replicating ChromaLock’s work would contain buying a TI-84 calculator, a Seed Studio ESP32-C3 microcontroller, and varied digital parts, and fabricating a customized PCB based mostly on ChromaLock’s design, which is obtainable on-line.
The creator says he encountered a number of engineering challenges throughout growth, 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 surface.

To accompany the {hardware}, ChromaLock developed customized software program for the microcontroller and the calculator, which is on the market open supply on GitHub. The system simulates one other TI-84, permitting folks to make use of the calculator’s built-in “ship” and “get” instructions to switch recordsdata. This permits 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 quick questions, but it surely has a downside in that it is gradual and cumbersome to kind 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 permits 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 digital camera function, although particulars had been sparse within the present demo.
ChromaLock claims his new machine can bypass widespread anti-cheating measures. The launcher program will be downloaded on-demand, avoiding detection if a trainer inspects or clears the calculator’s reminiscence earlier than a take a look at. The modification may also 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 take a look at in your calculator nearly actually represents an moral breach and/or a type of tutorial dishonesty that would get you in deep trouble at most faculties. So tread fastidiously, examine arduous, and keep in mind to eat your Wheaties.
