Build plans, tagged and honest.
Every project has a field tag, a status and a category. Right now every status is “planned” or “idea”. Nothing here is built yet, so these pages hold plans and open questions, not results.
Column tank aquaponics
A small acrylic column tank turned into a standalone mini aquaponics loop: tiny pump, clay-pebble basket on top, a pepper plant above, small fish and shrimp below.
Soil and water node
A small outdoor box that watches soil moisture, a pump and a water tank, and sends simple irrigation alerts. Solar-ready. Built to keep working on a poor connection.
Lab network
The lab wired like a small office: structured cabling, a patch panel, PoE cameras, VLANs and a VPN for getting in from outside.
Water-station safety controller
Leak detection and automatic shutoff for the lab plumbing, with tests that prove the shutoff works before anything is trusted to it.
Indoor starts to yard
Raising vegetable and pepper starts indoors, then moving them outside without losing them. The gadget angle: knowing when a start is ready, and when the yard is.
Sky ceiling PCB tiles
Custom LED circuit-board tiles that link together into a night-sky ceiling. Also the excuse to learn board design properly.
Backyard squirt turret
A pan-and-tilt water squirter for the yard. Low pressure, plain water, entirely silly. A fun way to learn motion control outdoors.
Photo diagnosis helper
Send a photo of a sick plant or a misbehaving setup and get a first-pass diagnosis. A human checks it before you rely on it.
The big tank window
A large aquarium set into the lab wall, with a flood-and-drain grow bed above it. The column tank, grown up.
