Finally found some time to bring my #NeoPixel Heart PCBs into a usable state and add some documentation. The #sourcecode is hosted on @Codeberg at https://codeberg.org/rommudoh/NoisyMcHeart and works for both variants (big and small).
I think I'll publish the #KiCad files soon, too.
Thanks to #platformio I can use the same code for both hardware variants.

Open source laser engraver sells for just $64 fully assembled — it is small and low power but may be enough for your needs - Europe Pub

>GitHub Link [https://github.com/Elias55745/mini-laser-printer?tab=readme-ov-file] > >A tech tinkerer has shared the full plans and resources necessary to build a compact desktop laser engraver. All the resources are available on GitHub, including the components list, 3D printer files, firmware, drivers, and software. Moreover, project creator Elias55745 is selling a fully assembled ‘mini laser printer’ created using these plans for just $64. They also intend to sell everything you need as a kit for self-assembly. However, the store is undergoing maintenance at the time of writing, so the shopping cart isn’t working, and you may see prices in Yen (I did).

So much cool uxn stuff happening these days. This card computer has been on my wishlist for a while.

Cool to see hackerspace adjacent groups here in Munich. I really need to get out of the house and try one.

One more (last one!) from (vessels)2 🚢 with Sistro Duo ✨

BASS ALERT 🎧 headphones strongly recommended 😌

"VIII: subscrub" 💆🫧 is the final movement in the piece. It is also the darkest sounding one 🖤 (and my personal favorite 👉👈). Just pure granular goodness 🌾

Build This Open-Source Graphics Calculator - literature.cafe

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 They rely on outdated technology and should not be nearly as expensive as they are, but market effects somehow keep prices well over $100 to this day.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.
