The calculator of the future, it has to be something like this

a calculator with ports to carry out all kinds of computer and electronic projects.

RE: Raspberry Pi inside NumWorks calculator
If everything was running on the Raspberry Pi, you wouldn't need to wait for it to boot up.
You'd also have to modify the bootup, eliminating the Linux self-test text to make the boot process faster.

Still, that's a nice mod.

RE: Raspberry Pi inside NumWorks calculator
My initial reaction was 'wow, what a waste of a lot of clever effort', but then it got down to the real heart of the device....

So cool... pocket DOOM... well, that's one killer app on a calculator that HP still has not delivered...

RE: Raspberry Pi inside NumWorks calculator
That's one way to get Mathematica.

Mathematica on a mobile device (calculator) A great project together would be to create our own hardware with RBπ + LCD + keyboard.

Something similar to AriCalculator

Another good community project can be a rasbcalc, something similar to raspad

If anyone is interested in helping develop the firmware for the AriCalculator project, please let me know.

RE: Raspberry Pi inside NumWorks calculator
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. :-)
