The home base. A README that opens with a branded hero, proves itself with a live screenshot, and gets a maker running in three commands — shown here in GitHub's dark theme.

Sprout
Tend a tiny jungle — four-channel soil monitoring & auto-watering.
Four independent channels — a sensor, pump & relay each.
Raw readings — raw ADC + 7 calibrated bands, no invented %.
Predictive watering — forecasts the next cycle per zone.
Live dashboard — dense control-room view, light & dark.

I kept forgetting to water my plants. So I built something that doesn't.
Meet Sprout: four soil sensors, four pumps, and a dashboard that gives every plant a mood. It waters before a leaf ever droops — and tells me what's coming next.
Open-source, built on an ESP32. Repo in the comments.

The feature I didn't expect to love: plants have moods.
Each channel reads its own soil and shows how it's doing — thriving, content, thirsty, parched. Not a gimmick: the mood is driven by calibrated data, never an invented percentage.
Turns out a little personality makes you actually care about the dashboard.

Lesson from building Sprout: the percentage was a guess.
Cheap soil sensors output raw ADC counts. Mapping that to a clean “83%” looks trustworthy — and isn't. I switched to raw values + 7 calibrated bands, and the watering got dramatically more reliable.
Full write-up and code in the repo. Calibration thread below.

Open-source plant care that treats every plant like it's alive. 4 sensors, 4 pumps, raw soil data. Built by a maker — no hype, just dirt.
Keep it one line, lead with the idea, link the repo. (Drop the playful last clause on formal channels.)
Pick 3–5 per post. #opensource + #maker for reach; #ESP32 + #embedded for the right crowd.

The committed brand files behind the mockups above — export-ready, metadata-stripped, and shared with the brand guide. SVG masters are the source; re-export the PNG at whatever size a surface stores. Drop these straight into a profile.

The seedling sits inside the inscribed circle, so a circular crop (Google · GitHub · social) only ever loses the corner ground. Reads down to ~40px.
Built for wide cover bands (Hackaday.io and the like). The surface re-crops it background-size:cover, centered, so the signature — edge seedlings, full-width moisture trace, seven-band hairline — lives in the vertical-center safe band, and the center stays dark for an overlaid name + summary. (The LinkedIn banner above is a different crop, 1584 × 396.)
