1. 01

   The whole FarmOne

   The stock trough runs the water point: a water meter on the inlet riser and a float sensor in the valve cover tell a cut supply from a stuck float or a leak, a probe and two heat cameras see ice, two cameras count every visit from both paddocks and watch for a calving, a beast down or a dog, and the brain in the cover turns that into calls on the trough's own lights and one app over LTE-M, all on solar.

2. 02Brain

   Raspberry Pi Zero 2 W (flat in the trough's valve cover, woken by the Walter board when stock come to the water)

   The brain: it runs the farmone-fw program

3. 

   03

   Water cameras (one per paddock)

   Behind the cover's water-side face, yawed 30 degrees to each side: cattle at the rim, the water surface, and out across that paddock

   Raspberry Pi Zero 2 W (flat in the trough's valve cover, woken by the Walter board when stock come to the water) · CSI-2 ribbon (one at a time through a 2-way camera switch, 150 mm, inside the cover) · Frames while stock are at the water; 10 s clips around calls

4. 04

   Heat cameras (one per paddock)

   Next to each camera: ice on the water, a cow lying out at night, a fox or dog in the dark, a hot head at the rim

   Raspberry Pi Zero 2 W (flat in the trough's valve cover, woken by the Walter board when stock come to the water) · I²C (to the Walter board, which wakes the brain) · 32 x 24 heat frames at 0.5 Hz, day and night

5. 

   05

   Water meter, float sensor and water probe

   The meter counts every litre in; the time-of-flight sensor reads the float's height; the probe reads the water temperature

   Raspberry Pi Zero 2 W (flat in the trough's valve cover, woken by the Walter board when stock come to the water) · GPIO pulse (meter) + I²C (float) + 1-Wire (probe), all to the Walter board · Litres per minute, float height every minute, water °C every 5 min

6. 06

   Air sensor and mic

   Air temperature and humidity behind the end vents (frost, dew point, heat-stress index); the mic hears calving bellows and distress calls

   Raspberry Pi Zero 2 W (flat in the trough's valve cover, woken by the Walter board when stock come to the water) · I²C (SHT45) + analog to the Walter ADC (mic) · Air every 5 min; sound level and short clips when stock are near

7. 07

   Call lights, tone and secure element

   Red, amber, blue or white on the call light facing each paddock with a tone; every call signed; the tamper switch marks the log if the cover is lifted

   Raspberry Pi Zero 2 W (flat in the trough's valve cover, woken by the Walter board when stock come to the water) · One data wire (lights) + GPIO (tone, tamper) + I²C (secure element) · Light colour and flash, tone, signatures, tamper flag

8. 08

   Solar, cells and LTE-M

   The 6 W panel flush in the cover top charges four cells; the Walter board stays awake on little power, reads the water sensors, wakes the brain and sends every call over LTE-M with its GNSS position

   Raspberry Pi Zero 2 W (flat in the trough's valve cover, woken by the Walter board when stock come to the water) · 5 V rail + UART to the brain · About 10.8 Wh a day (est.); calls, the hourly log and the trough's position over LTE-M

1. 4 Nov 2026, 03:44LatestA grazing farmer buys FarmOne as the 600 L stock trough a paddock already needs, on the fence line between two paddocks, with the float valve and its air gap kept and no mains at the water point. So the electronics must be one board an assembly house makes and tests the same way every time, inside the trough's own valve cover, running on the 6 W panel in its top, with nothing plugged together inside.

   • What we designed: one rigid-flex board round the water meter in the valve cover. An 8-layer main wing on the paddock A side carries the RV1126B with a heat block to the cover floor over the shaded float bay, memory, the security chip, the microSD card with our software, the always-on ESP32-S3, the LTE-M modem with a soldered eSIM and a GNSS patch beside the solar panel, the float-height chip over its floor window and the tamper switch. A flex bridge on the floor, between the water-side face and the inlet pipe, joins a 4-layer power wing on the paddock B side with the solar charger, four soldered 18650 cells and their thermistor, the sounder and solder pads for the panel, the water meter and the probe. Four small tabs on flex arms hold a camera chip and a heat chip for each paddock behind the water-side face, two lamp strips sit under the call-light slots, and an end strip carries the mic and the air chip. It replaces the Raspberry Pi Zero 2 W, two camera modules, two heat-camera boards, the Walter LTE-M board and seven other bought boards. See /build/farmone-boards
   • How we checked it: the board is written as code and opened in KiCad (0 design-rule violations). The code places 72 parts at their sizes and checks each sits on its piece inside the cover's rounded outline, clear of the water meter and the inlet pipes, with no overlaps and room for its height; that each camera and heat tab, holder and lens stays 0.3 mm inside the water-side face; and that all 20 water-point calls (cows at the rim, an animal down, a calf 3 m out, a fox across the paddock, the far end of the water, a hot head, calving at night, ice) are in view from where the chips really sit. The shared design review gives 27 pass, 1 fixed, 5 to prove and 0 fail: about 66 hours on four aged, cold cells (two days of cloud), a fox 7.4 m away about 87 pixels tall.
   • What we learned: with our lenses just inside the face on tabs turned 30 degrees to each paddock, the rays to the calls cross the 4 mm face up to 13 mm off the window centre, so the round windows would cut the view. The camera windows grow from 18 mm round to 25 x 18 mm and the heat windows from 16 mm round to 25 x 18 mm in the rev T cover CAD, in the same run.
   • What is next: the rev T trough CAD with the board inside, the tamper pin on the bay partition, the flex arms with the flex maker, and the next board, BayOne.

2. 30 Oct 2026, 00:30Phase 4 starts with one product: parts are ordered, built and tested for one before the rest. Our phase 1 close-out plan (task C9) asks for all 24 products to be scored on the same points, with sources, so the first build is chosen on evidence.

   • All 24 stage 2 products scored from 1 to 5 on six points: demand (do buyers already pay for these jobs), reach (who signs and how fast), parts cost, ease of building, certification risk and time to a working unit on a real site (all est., from the stage 2 buyer checks and our pricing table)
   • What we learned: the products whose first job works from signals the item already carries, at a low parts cost and with no safety, medical or child-safety approval in the way, score highest; products with a large custom body or a public tender score lowest, however strong their need
   • A recommended first product and a runner-up, with the reasons and the risks to manage, are with the owner, who decides; we will publish the choice once it is made
   • Next: close-out C10, a /line page showing all 24 products by group, then phase 2 marketing

3. 29 Oct 2026, 03:30A grazier with 3 to 30 troughs drives a water run every day, because a cut pipe or a stuck float can leave a mob without water within hours, and a calving or a dog among the stock is found only when someone looks. Today the farm buys the trough (a 600 L JFC trough is £318 ex VAT at Tanks Direct), a level monitor (Farmbot Trough Direct A$749 on the NSW DPI catalogue, Ranchbot $489 at its US launch, plus a plan) and a calving sensor (Moocall $329 + $150 a year).

   • Buyer check with sources: Tanks Direct trough prices, Farmbot and Ranchbot Trough Direct level monitors, Moocall calving sensors; no camera trough found on the market
   • What we learned: the leading trough monitors read the water level only, so a cut supply shows when the trough is already low; and the trough itself costs about $420, not the $300 we assumed
   • Parts list prices checked on shop pages today: $1,107 per trough at qty 1 including the trough (the page said $990); the Pi Zero 2 W, Camera Module 3 Wide and float sensor cost more, the solar panel less
   • Price raised from $1,290 to $1,490 + $9 a month per trough, because the qty 1 cost had reached the old price; cost and margin table in the design notes: about $1,287 at qty 1 and $840 at qty 100, a 14 % to 44 % margin (est.)
   • All 23 part fit checks and 21 camera and sensor views in the CAD still pass; about 4 days with no sun rechecked; CAD review clean with no floating parts and no collisions
   • Product page: the first three FAQs answer why not a trough monitor and a calving sensor, what it costs, and whether the farmer has to replace the trough; a power and size spec group
   • Next: three questions for farmers in customer reviews (a new trough or a retrofit cover, which calls decide the sale, who else gets the alerts and is LTE-M enough), then PumpOne for water, energy and utilities

4. 28 Oct 2026, 11:27A grazing farm needs one thing at each water point that calls a cut supply, a stuck float or ice before the stock go without, and watches the mob that comes to drink: calvings, an animal down, a dog at the water. Water rules keep the float valve and its air gap (Northumbrian Water Guidance Note 9, BS 3445), the welfare rules ask for fresh, clean, unfrozen water every day, and farmers pay about A$749 for a trough monitor (Farmbot) before a flow sensor, a calving camera and a gateway.

   • Market check: who buys one product per water point (beef, sheep and mixed farms with 3 to 30 troughs), what they pay for trough monitors, flow sensors and calving cameras (Farmbot, Gallagher), and the water fittings and welfare rules for troughs; sources in DESIGN.md
   • New CAD: the 600 L oval stock trough (1,610 x 1,180 x 840 mm) with a smart valve cover over the float bay: a Raspberry Pi Zero 2 W brain, two cameras and two heat cameras (one pair per paddock), a water meter on the inlet riser, a float sensor, a water probe, an air sensor, a mic, LTE-M and GNSS, call lights, a tone, a secure element, a tamper switch, a flush 6 W solar panel and four cells; 23/23 parts fit from datasheets, 21 camera and sensor views checked, no collisions, no floating parts
   • equipment.json: 10 rules met (float valve and air gap kept, same size, no overhang, solar only); 9 calls (7 alone), 4 impact cases and every security key
   • idea.json fence-line plan, integration.json (6 parts, 5 app screens with a Nobody on the farm mode), bom.csv (about $990 a trough with the body), buy.json with 8 key parts
   • New product page at /products/farmone/ in Agriculture: $1,290 + $9/month per trough against about $1,524 + $135/year bought separately (est.); folds TroughTally, CalvingPen and CalveClock; orchard frost, moth traps, crop raiders, pivots, sprayers and smoke stay with FarmMast, FrostMast, TrapTop, PestTrap, RaidPost, EndGauge, FanLamp and FieldEdge; next: F15 Water, energy and utilities

Smart equipment · legal on the field

FarmOne is the stock water trough, made smart

It replaces the farm's plain 600 L trough at the same water point (for example a JFC DT600FF), on the same base and the same 25 mm supply; the float valve, its air gap and the farm's water main stay, with every part built in. Everything inside the trough's own valve cover: brain, two cameras, two heat cameras, the water meter, float sensor, probe, air sensor, mic, LTE-M and GNSS, call lights, tone, secure element, tamper switch, the 6 W panel flush in the top and four cells. The cover stays 120 mm tall, inside the trough outline. About +2.4 kg over a plain cover (est.); no mast, pole camera, gateway or separate meter box.
