Hey everyone!
I wanted to share a project I’ve been working on:
The **“nternet-Link”**
It’s an external module for the TI-Nspire CX and CX II calculators that connects through the USB port and lets the calculator communicate with an ESP32. The idea is to treat the calculator as a handheld interface (screen + keyboard) while the external hardware handles networking, communication, and experimentation with embedded systems.
I’ve documented the builds, hardware, and demos here:
**GitHub:** https://github.com/OtterCadGH/nternet-Link/blob/main/V2_nternet-Link.md
**Demo Video:** https://www.youtube.com/@OtterCADyt
I’d genuinely love feedback, suggestions, or ideas from the community — especially from people who have messed with the ASI interface, USB behavior across CX models, or similar accessories.
**Important disclaimer:**
This project is NOT intended to be used during exams, quizzes, or any academic assessment, and I do not support or condone cheating in any way. Many schools prohibit external communication devices or modified accessories during testing, and this should absolutely be treated as an at-home electronics and programming project only. Please follow your institution’s rules — if someone tried to use this during a test, that would be entirely against the purpose of why I built it and I don’t want it used that way.
Thanks for taking a look, and I’m happy to answer questions!
