GH: https://github.com/El-EnderJ/NeoCalculator [https://github.com/El-EnderJ/NeoCalculator] >Graphics calculators are one of those strange technological cul-de-sacs. They rely on outdated technology and should not be nearly as expensive as they are, but market effects somehow keep prices well over $100 to this day. Given that fact, you might like to check out an open-source solution instead. > >NumOS comes to us from [El-EnderJ]. It’s a scientific and graphic calculator system built to run on the ESP32-S3 with an ILI9341 screen. It’s intended to rival calculators like the Casio fx-991EX ClassWiz and the TI-84 Plus CE in terms of functionality. To that end, it has a full computer algebra system and a custom math engine to do all the heavy lifting a graphic calculator is expected to do, like symbolic differentiation and integration. It also has a Natural V.P.A.M-like display—if you’re unfamiliar with Casio’s terminology, it basically means things like fractions and integrals are rendered as you’d write them on paper rather than in uglier simplified symbology.

Normally where are sprinkler water valves located? I'm wanting to build a watering system for my outdoor potted plants that has a few outputs for different groups of plants or planter/pot sizes, but keeps looking like pricey garden valves are the norm, and I just want to anti-ADHD-ify my plants.

Probably going to use ESPHome's sprinkler component since you can set when multiple valves are needed to hit a target zone.

I am starting a series of solar deck/cyberdeck Shedtronic Workshop projects. This is an early devlog. Follow along on substack if you are interested. These are all going to be about portable resilient solar tech projects and finding ways to run tech off-grid.
