Numworks: open-source, Python-compatible handheld graphing calculator

You may want to check out: The whole calculator running in a browser, thanks to emscripten : https://www.numworks.com/simulator/ An interactive PCB viewer, in the browser again : https://www.numworks.com/resources/engineering/hardware/elec... Full schematics https://www.numworks.com/resources/engineering/hardware/elec... And of course the whole source code to the operating system, https://github.com/numworks/epsilon

I have one of these. It’s a nice little device but it falls a bit short in one key area: it lacks a CAS (Computer Algebra System) for symbolic calculations. That functionality was available in an earlier release of the software (Epsilon) but it was at best rather rudimentary. I’ve flashed Omega (a fork of Epsilon that preserves the rudimentary symbolic capabilities of earlier Epsilon) which also allows running third-party apps (including Xcas).

Mods, please correct the editorialized and wrong title. NumWorks isn't open source and never was. What it is is source-available, because the source is available. Or at least it still was available the last time I looked at it. NumWorks used to be fun because it had an unlocked bootloader, allowing users to download their own software onto the calculator. But then they did a face-heel turn. To NumWorks' credit, I'm sure the UI is still miles ahead of Texas…

I've seen this type of thing pop up before, usually as a small linux computer running octave
