Three small loops, one shared brain.
HKOS — the Home Kibbutz Operating System — is the methodology turned into a runnable thing for a single house. Today there's one loop running and two more being built: fish in a basement, bees in the yard, a raised bed in the garden. They write to the same brain. The point is the wiring, not the substrates.
Node Zero is live. Node One and Node Two are being built. Honest status below.
Node Zero — Aquaponics
New England basement · running since 2026-03-27
A cold-water aquaponics cell in the basement: pH probe, water-temp probe, heater on a relay, plants in a tent, fish on the way. A Raspberry Pi reads sensors every thirty seconds and writes to a local logger and the brain.
- Atlas pH probe (I²C 0x63)
- DS18B20 water temp (GPIO4)
- 200W heater on relay
- Raspberry Pi 4 + breadboard
- Grow tent + 40-gal sump
Enclosure, soldered sensors, three goldfish cycling, then the first ML pass on the accumulated dataset.
Build details in the log. Full ops in the manual.
Node One — Bees
Backyard · bees arriving 2026-05-09 · sensors ~2 weeks out
Two hives in the backyard. The sensor stack — hive weight, internal temperature gradient, acoustic queen detection — runs the same Pi-and-capture pattern as Node Zero. The honey itself ships separately at goldshoney.com.
- 2 hive bodies + frames
- Smoker, suit, hive tool
- Package of bees — arriving 2026-05-09
- Load cells + DS18B20 array (on order)
- Piezo mic for acoustic capture
Hive installed the week of May 11. Sensor build target around 2026-05-22.
First reading flips the badge to LIVE.
Node Two — FarmBot raised bed
Side yard · assembly week of 2026-05-11
A FarmBot Genesis on a raised bed, fed by a 30-gallon cistern off a rain barrel. Every action and reading writes to the brain on the same capture pattern, so the bed's history becomes searchable next to the basement's.
- FarmBot Genesis kit (unboxed)
- Raised bed lumber
- 30-gallon cistern
- 50-gallon rain barrel + diverter
- Soil, seeds, drip line
Assembly the week of May 11. First plantings as soon as it's bolted together.
Cistern + rain barrel before the next big rain.
Same pattern, different substrates.
Every node POSTs to the same /capture endpoint with a domain tag — aquaponics, bees, garden. Captures get embedded and stored in a shared vector index, so a temperature trend in the basement is retrievable next to a weight trend on a hive. Domain scoping keeps queries clean; one shared index keeps the cross-substrate questions possible.
The architecture pattern — capture grammar, sensitivity tiers, retrieval surfaces — is documented at /p/hob.html.
- Atlas pH + DS18B20 temp + heater on relay
- Raspberry Pi capturing every 30 seconds
- ~80,000 readings since March 27
- Brain ingesting daily session captures
- Bees installed in hive (week of May 11)
- FarmBot assembled on raised bed (week of May 11)
- Hive sensors live — weight, temp, acoustic (~2 weeks)
- First cross-domain query in the brain
