From the project

Open source scientific calculator built on Raspberry Pi Pico W — custom PCB, WiFi messaging, IR projector control and games.

A fully custom scientific calculator built on the Raspberry Pi Pico W, designed specifically for students. Features wireless peer-to-peer messaging, IR classroom projector control, a custom PCB, and built-in games — all running on MicroPython.

PicoCalc is an end-to-end hardware and software project encompassing PCB design, embedded systems programming, wireless networking, and circuit design. Every component — from the button matrix to the IR driver circuit — was designed, calculated, and implemented from scratch.
