1. 01

   The whole DockOne

   The dock door's two track guards run the door: two door cameras look across the doorway into the trailer, a dock camera and a radar watch the forklift lane, and the brain in guard A turns that into trailer, open-edge, creep, pallet and door calls on the guards' own lights and one dock app.

2. 02Brain

   Raspberry Pi 5 (in guard A's sealed top bay)

   The brain: it runs the dockone-fw program

3. 

   03

   Guard A door and dock cameras

   The door camera looks across the doorway into the trailer (trailer, edge, creep, pallets); the dock camera watches the dock floor and the forklift lane (people, hi-vis, strikes)

   Raspberry Pi 5 (in guard A's sealed top bay) · 2 x CSI-2 ribbon · 5 fps door frames and 2 fps dock frames, checked on the brain; a 12 MP still of each pallet

4. 

   04

   Guard B door camera

   The second door camera, from the other side of the door: stereo with guard A for trailer creep, pallet height and the far rear post

   Raspberry Pi 5 (in guard A's sealed top bay) · Shielded 5 V and data lead in the door header conduit (encrypted), BLE LE Secure Connections as back-up · Door frames with time stamps; light and tone commands back

5. 

   05

   Approach radar

   Forklift speed and people coming to the door, up to 6 m, through guard B's front window

   Raspberry Pi 5 (in guard A's sealed top bay) · UART to the XIAO in guard B · Up to 3 targets: range, angle and speed at 10 Hz

6. 

   06

   Strike and door air sensors

   A strike sensor in each guard logs forklift hits; the air sensor in guard B sees warm air at a cold-load door left open

   Raspberry Pi 5 (in guard A's sealed top bay) · I²C (STEMMA QT) · Strike g level and time; air temperature and humidity every 30 s

7. 07

   Call lights, tone and secure element

   Green, amber and red door calls on both guards with a horn tone; every call signed; the tamper switch marks the log if a cap is opened

   Raspberry Pi 5 (in guard A's sealed top bay) · One data wire + GPIO + I²C · Call colour, tone, signatures, tamper flag

8. 

   08

   Power from the dock door circuit

   Turns the dock door's own 120 V circuit into 5 V inside guard A's sealed bay, and feeds guard B through the header lead

   Raspberry Pi 5 (in guard A's sealed top bay) · 5 V rail · Power, about 7.5 W per door (est.)

The idea

The dock door's own guards see the trailer, warn of the open edge and creep, count every pallet and run the door

How the parts connect

DockOne, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

What controls DockOne

while True:
    a, b = door_a.frame(), guard_b.frame()
    trailer = rear_posts(a, b)                 # stereo range to the trailer
    targets = guard_b.radar()
    calls = edge_rule(door_open(a), trailer, targets) + creep_rule(trailer, history)
    calls += pallet_rule(a, b, order) + lane_rule(targets, dock.frame())
    calls += door_rule(door_open(a), guard_b.air()) + strike_rule(imu_a, guard_b.imu())
    for c in calls:

1. 4 Nov 2026, 01:34LatestA warehouse buys DockOne as the pair of steel track guards at a dock door, so the electronics inside both guards must be boards an assembly house makes and tests the same way, with nothing plugged together inside, mains handled by a certified supply (IEC/UL 62368-1), boards that survive forklift strikes (PAS 13:2017), and cameras that see the trailer, its creep and the dock floor through the steel.

   • What we designed: one rigid-flex board in each of the two steel guards, the first on our bigger RK3576J core. In guard A an 8-layer main board, 166 by 142 mm, sits 12 mm over the steel bay plate, with the RK3576J pressing an aluminium block into the plate (the guard is its heat sink), 4 GB memory, 32 GB eMMC, a certified 5 V supply soldered on for the dock door's own 120 V circuit, its fuse and push-in terminal, and the latched lead to guard B. A strip behind the front face carries the call lights, the sounder, the Wi-Fi module behind a new antenna window and the dock camera chip; a strip behind the nose carries more call lights and the door camera chip. Each camera chip is on a small tab cut from its strip, held on its aim by a printed bracket. Guard B has the same three pieces with the ESP32-S3, an OV2640 door camera chip (the second view for stereo), the 60 GHz radar chip 4 mm behind its window and the air chip. It replaces the Raspberry Pi 5, two Camera Module 3 boards on ribbons, the XIAO ESP32-S3 Sense, the radar, motion, air and security boards and four LED sticks. See /build/dockone-boards
   • How we checked it: both boards are written as code and opened in KiCad (0 design-rule violations). The code places 91 parts at their datasheet sizes and checks each sits on its board with no overlaps and fits its gap; that the call lights, sounders, radar, air chip and antennas sit behind their openings in the guard design; and, in 3D, that each camera's holder clears the steel by 0.3 mm, its tab clears its strip, and every one of the 14 door and dock calls in the guard design is inside its camera's view. Design review with the shared rules: 24 pass, 1 fixed, 10 to prove, 0 fail. A 3D model shows both guards see-through or laid flat, and the quote pack and design files are on the board page
   • What we learned: the bench cameras sat behind 20 mm holes turned 35 and 30 degrees from the steel face, so much of their view was the inside of the guard, and a first try with a wide 100 degree lens needed a hole wider than the guard. Choosing each lens from its calls (60 degrees with the door chip turned on its side, 70 degrees for the dock), and putting the lens front just inside the face, keeps every call's line of sight within 67 degrees of the face through 44, 40 and 28 mm holes with flush clear covers. This is a new shared lesson for every board with a turned camera. A 20 mm creep step 3 m away fills 13 pixels on guard A and 7 on guard B against the 4 needed (est.). The shared quote tool now names each board's own Rockchip core, so V2 boards get the right quote. About $139 a door in electronics at 1,000 (est.)
   • What is next: the RK3576J outline and ball map from Rockchip's datasheet; the rev T guard CAD with the bigger camera holes, the antenna windows, the camera brackets, the cap magnet pocket and the conduit entry, with every board part checked in 3D; the window heater for freezer docks; and the next product's board, CareOne

2. 30 Oct 2026, 01:46OSHA renewed its National Emphasis Program for warehouses and distribution centres on 31 July 2026 for five years, with loading docks and forklift and pedestrian interactions named for particular attention and injury records reviewed for four years (ASSP, August 2026; J. J. Keller). At the same door, carriers bill detention after about two free hours, on average $63.71 an hour in ATRI's survey, and there is still no federal rule (J. J. Keller; FreightWaves).

   • Market and rules check (DESIGN.md): OSHA's renewed warehouse emphasis programme CPL 03-00-026 (31 July 2026, five years), ATRI and FreightWaves on detention fees and FMCSA's open study, and ANSI MH30.3-2022 still the latest restraint standard, each with what it changes in DockOne (sources M1-M5)
   • New assist call: a signed monthly dock safety record per door (open edges and how close people came, creep calls, fast forklifts, people in the lane, strikes, doors left open, and the door's temperature); gaps in the log are shown as gaps; a record aid, never a compliance claim. Now 10 calls (7 alone, 3 assist)
   • Signed in and out times at each door now export per carrier for detention disputes; the guards see only the door, so gate and yard time stay with the yard's own log
   • No CAD change and no new part; price kept at $1,290 per door + $49/door/month; one new rule line in equipment.json and a demo app line
   • Product page https://iemilabs.com/products/dockone/ gains two FAQs (OSHA inspections, detention bills) and a records spec
   • Next: ask distribution centres and 3PLs in the phase 3 buyer review whether signed door times and the dock safety record are reasons to buy; the next run checks CellOne

3. 29 Oct 2026, 05:55Before customer reviews and building, the 24 stage 2 products should be built from as few different parts as the jobs allow, so a first pilot run buys in quantity, there are fewer firmware bases to keep secure, and every customer uses one app. This is close-out task C1 in our phase 1 plan.

   • New line review page products/LINE-REVIEW.md, section "Shared parts": one table of the brain, camera, radar, radio, cell, charger, secure element, tamper switch and app each product uses, with how many products use it, the quantity in one set of all 24, the price and a source link
   • What we learned: the stage 2 runs had already pulled the line onto three brains (Raspberry Pi Zero 2 W in 13 products, Raspberry Pi 5 2 GB in 6, XIAO ESP32-S3 in 5), two main cameras, one heat camera, two radars, one cellular radio, and the same secure element and tamper switch in all 24
   • The few parts that stay different each have a job reason written down: the baseball speed radar, the narrow finish-line camera for athletics, the flat backup cell where an 18650 does not fit behind the lens, and the cheaper presence radar where only presence matters
   • Cell price unified: the Samsung 35E cell is $6.99 today, and four parts lists still had $4.99-5.00 (CricketOne, FootballOne, RacketOne, CareOne); they now match, raising their parts cost by $4 to $36
   • Part number fixed: DockOne's second door camera is the XIAO ESP32-S3 Sense (113991115); its parts list had the plain board number
   • One set of all 24 uses 66 cells, 47 tamper switches, 34 secure elements, 23 Camera Module 3 Wide and 21 Pi Zero 2 W boards, enough to buy at distributor price breaks from the first pilot run (est.)
   • Next: close-out C2, overlaps and gaps between products that work in similar places (for example StudyOne and ClassOne, BedsideOne and CareOne), then C3, one pricing table that carries these cost changes onto the product pages

4. 29 Oct 2026, 01:27A distribution centre needs each dock door to warn at an open edge and when a trailer creeps with a forklift inside, and to prove every pallet count: about 33,000 US workers missed work after dock and ramp injuries from 2015 to 2020 (BLS, via HSE Blog), and OSHA 1910.178(k)(1) requires the trailer to be held. Today light kits (Rite-Hite Rite-Vu) and dock camera software (Roboflow, Zimark) are separate systems, all priced on quote.

   • Buyer check with sources: Rite-Hite Rite-Vu light and restraint kits and GMR POWER CHOCK Auto through dealers, IDEALVu restraint camera, Roboflow dock safety and pallet counting on existing cameras, Zimark proof of load; none has a public price
   • What we learned: buyers pay one vendor for steel and lights and another for camera software on the wall; nobody puts the camera, the call and the light in the guard already at the door
   • The Raspberry Pi 5 4 GB is now $130, so the brain is the same-size 2 GB at $90; all 16 camera and radar views in the CAD are unchanged
   • Parts list prices checked on shop pages today: $796 per door at qty 1 (the page said about $760); a broken row in the parts list was fixed; cost and margin table in the design notes (about 31 % at qty 1 and 48 % at qty 100, est.)
   • Price kept at $1,290 + $49 a month per door against about $2,374 + $278 bought separately; freezer docks counted with the heater pad (11.5 W, inside the 20 W supply)
   • Product page: the first three FAQs answer why not a light kit or camera software, what it costs per door, and that it warns but does not hold the trailer; a power and size spec group
   • Next: three questions for distribution centres in customer reviews (replace working guards or only at refit, price against quote-only rivals, which call pays first), then CellOne for manufacturing

5. 28 Oct 2026, 09:45A warehouse needs one thing at each dock door that warns when the edge is open or a trailer creeps or pulls away with a forklift inside, and counts every pallet with a photo. About 33,000 US workers missed work after dock, dock-plate and ramp injuries from 2015 to 2020 and 49 died (BLS, via HSE Blog), and OSHA 1910.178(k)(1) requires the truck to be held while forklifts board it.

   • Market check: who buys one product per dock door (warehouses, distribution centres and 3PLs), what they pay today for track guards, dock lights, restraints and pallet cameras, and the OSHA dock rules; sources in DESIGN.md
   • New CAD: the two 48 in steel track guards of a 9 ft dock door, with a Raspberry Pi 5 brain, door and dock cameras, a second door camera, a radar, an air sensor, strike sensors, call lights, tones, secure elements, tamper switches and a potted supply in their sealed top bays; 19/19 parts fit from datasheets, 16 camera and radar views checked, the door opening, height and track notch checked, no collisions, no floating parts
   • equipment.json: OSHA 1910.176(a), 1910.178(k)(1), 1910.26, 1910.28(b)(1)(iii) and 1910.144, PAS 13 impact, New York 52-c staff notice; 9 calls (7 alone), 4 impact cases and every security key
   • idea.json dock plan, integration.json (6 parts, 5 app screens with a mode for when no dock lead is at the door), bom.csv (about 60 a door), buy.json with 8 key parts
   • New product page at /products/dockone/ in Logistics: $1,290 + $49/door/month against about $2,374 + $278/door/month bought separately (est.); folds LoadingDock AI and DoorPost; the yard, the forklift cab, goods in transit and site entrances stay with their own zones; next: F10 Manufacturing plants

DockOne is the steel door-track guards, made smart

It replaces the dock door's existing pair of door-track guards (or the bare tracks), at the same place on the same floor bolts, with every part built in. Everything inside the two guards' sealed top bays (z 995 to 1,226 mm): Raspberry Pi 5, two cameras, the second camera, radar, air sensor, two strike sensors, four call lights, two tones, two secure elements, two tamper switches and a potted supply. About +1.4 kg per pair over plain guards (est.); no wall camera, pole, light box or leveler sensor.
