Graphing Scientific Calculator Based on the ESP32 (github.com)

"Construccion" link is broken. And where is schematic?

The site is broken, "Read the manifesto" and "View specs" links don't work.

  THE MOAT
  100% OPEN
  Open Source
  Hardware and software that belongs to everyone.

And misleading.

Also, what's up with all the junk in readme? The project structure, random stats, tables. How bloating readme should help?

upd: Okay, there is a tiny disclaimer that the project is vibe-coded.

The first thing I noticed in the repo is a next config, which I couldn't fathom. I then realized this is the "marketing website" for the project.

Deploying a neo-vibey website for a calculator is a wild choice. On top of that, the first things (the buttons) dont work.

This does not spark the vibe I want. You either go full hacker-mode (and end up with a relatively nerdy website that is more about technicals and less about marketing), or you go full-on stakeholder-mode (you prioritize that your product is going to completely smash your competitor, making stakeholders feel FOMO).

I don't get it. At all.

The photos in the readme are great but the files are huge, 3-5mb+ per file (in case anyone here is on limited data).

I wonder it this could be easily ported to the TTGO esp32 deck? It’s fairly mature and a nice form factor.

If you want a serious OSS calculator, a great choice is the Free42 project by Thomas Okken, which is a GPL-licensed project that is entirely compatible with the HP-42.

Not really a graphing calculator (although you can plot a bit) but is a proper old-school rpn scientific calculator with programming, numerical integration and solver, amazing complex number support etc, and has stood the test of time. All the things you would expect if you've used an HP-42 or similar.
