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. + +## Materials + +This will be a work-in progress list. + +* Raspberry Pi Zero +* >4GB microSD card Class 10 +* "TinyLCD35" 3.5 inch TFT Display with pcb for Raspberry Pi Zero from NeoSec +* 4x AAA battery holder +* 4x AAA batteries +* 5V VRM +* SPST power switch +* USB OTG Cable +* iPazzPort Wireless Mini Handheld Keyboard +* 3D printed case (Design will be provided) +* Custom-booting Raspbian Lite \ No newline at end of file
