I've always liked portable builds of the raspberry pi if it was mini laptops, pi game-boy consoles or even pi phones, but I've never seen anyone do it with a calculator casing.
It is of special interest to me as I would have loved to have such a toy while I was in high-school and be able to code, play games or just cheat on math tests with all the discretion this cover should bring.
In this project I will be attempting to make a portable raspberry pi encased inside a ti-30 Eco calculator case. The goal being a somewhat usable pi computer that uses the calculators buttons to interact with has a chargeable battery and an LCD screen.
This is my first project so I don't expect it to go perfectly, follow along if it is of interest.
