From the project

Custom embedded calculator hardware design (KiCad) with integrated LoRa communication and low-power system architecture.

CalcText is a wireless messaging device enclosed inside a scientific calculator, powered by a single AAA battery. Two units can message each other directly over LoRa, not requiring Wi-Fi, mobile data, or any kind of external infrastructure. The idea came to me from wanting to message a friend who sat far away from me in my maths class without using my phone or shouting. Despite being a little odd, the idea stuck with me.
