# rpy-calculator
|
|
|
|
We are making a calculator out of a Raspberry Pi and an LCD screen!
|
|
It'll boot straight into a Python interpreter for use as a desktop calculator, the way the original Python was intended to be used.
|
|
|
|
## Purpose
|
|
|
|
Python makes for a great scriptable calculator! It would be super cool to make a compact calculator that presents the user with a Python interpreter to use for solving complex problems.
|
|
CW still has one year of college left, and since he loves Python so much, he wants to ditch his graphic calculator in favor of it!
|
|
Also, it'll just be fun to play with some hardware for a change!
|
|
|
|
## Methodology
|
|
|
|
This project will attemt to construct as compact of a device as possible while still retaining usability of input and graphing capabilities.
|
|
In order to do this, a Raspberry Pi Zero will be used along with a 3.5" LCD screen that attaches using the SPI interface of the GPIO on the PiZ.
|
|
A separate, wireless handheld keyboard will be used for input.
|
|
