On Saturday, a YouTube creator known as “ChromaLock” revealed 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 System,” demonstrates a customized {hardware} modification that enables customers of the graphing calculator to kind in issues despatched to ChatGPT utilizing the keypad and obtain reside responses on the display screen.
ChromaLock started by exploring the calculator’s hyperlink port, usually used for transferring instructional 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 parts to interface with the calculator’s methods.
It is value 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 primarily based on ChromaLock’s design, which is accessible on-line.
The creator says he encountered a number of engineering challenges throughout growth, together with voltage incompatibilities and sign integrity points. After creating 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 obtainable 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 information. This enables a person to simply obtain a launcher program that gives entry to varied “applets” designed for dishonest.
One of many applets is a ChatGPT interface that may be most helpful for answering brief questions, nevertheless it has a disadvantage in that it is sluggish and cumbersome to kind in lengthy alphanumeric questions on the restricted keypad.
Past the ChatGPT interface, the gadget 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 gadget can bypass frequent anti-cheating measures. The launcher program may be downloaded on-demand, avoiding detection if a instructor 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 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, research onerous, and keep in mind to eat your Wheaties.
