Raspberry Pi inside NumWorks calculator

[tcab]

Here is my poor man's attempt at a Raspberry Pi calculator. Off the shelf components only - Raspberry Pi screen touchscreen, rechargeable USB power module, USB numeric keypad - running Mathematica (which comes for free with Raspberry Pi linux).



I can also run Jupyter Notebooks with the full power of Python, R, Julia or Scala. Comes with Wifi and thus internet access. Uses bluetooth to allow an external keyboard and mouse to be used (not pictured), so not really a calculator I suppose.

Am thinking of swapping out the numeric keypad with a tiny qwerty + mouse bluetooth keyboard, making it totally self contained. I can then get flatter usb cables and keep the usb wiring inside the case. Oh yes, obviously a better case, too but I will keep the usb ports exposed.

Yes its not a serious project, so please don't scold me. I just wanted to see how far I could get plugging together standard USB components with no special software or electrical wiring whatsoever. :-)
