1. 01

   The whole CellOne

   The machine's signal tower runs the cell: the four lamp lines tell it what the controller says, a cell camera and a heat camera in the sensor tier see the gate, the dials, the heaters and the bin, and the brain in the base turns that into state, gate, dial, heat and bin calls on the tower's own lamps and one cell app.

2. 02Brain

   Our tower board: the Rockchip RV1126B on the base disc

   The brain: it runs the cellone-fw program

3. 03

   Cell camera

   Looks 45 degrees down to the operator side: the gate, the operator, the hydraulic pressure and oil temperature dials, the part bin and the floor in front

   Our tower board: the Rockchip RV1126B on the base disc · the board's own riser flex (2-lane MIPI CSI-2, no ribbon) · 2 fps frames checked on the RV1126B AI engine; 10 s clips around calls

4. 04

   Heat camera and mic

   The heat camera looks along the barrel at the heater bands, nozzle and hopper dryer; the mic hears the machine's alarm beep and air hiss

   Our tower board: the Rockchip RV1126B on the base disc · I²C over the wall flex (heat chip) + PDM over the mic flex (digital mic) · 32 x 24 heat frames at 2 Hz; sound level and short clips

5. 05

   Tier-line inputs

   Read the four 24 V lamp lines the machine controller already drives through isolated 24 V inputs (IEC 61131-2 type), so the tower knows run, alarm, auto and operator calls exactly as the controller means them

   Our tower board: the Rockchip RV1126B on the base disc · GPIO through the isolation barrier · Four line states at 20 Hz

6. 06

   Cycle and strike sensor

   Feels each machine cycle through the guard (the count and cycle time) and logs knocks and strikes on the tower

   Our tower board: the Rockchip RV1126B on the base disc · SPI on the base disc · Cycle times; knock g level and time

7. 07

   Lamp tiers, tone and secure element

   The red, yellow, green and blue tiers show the machine state as before and flash each call, with a tone; if the brain stops, a watchdog hands each tier straight back to its controller line; every call signed; the tamper switch marks the log if the tower is opened

   Our tower board: the Rockchip RV1126B on the base disc · The centre spine flex (four lamp lines and the sounder) + I²C and GPIO on the disc · Tier colour and flash, tone, signatures, tamper flag

8. 08

   Power from the tower lead

   Takes the machine's own 24 V DC tower feed through the tower's M12 socket, makes 5 V, and keeps the brain alive about 2 s (est.) on supercapacitors to sign the power-off

   Our tower board: the Rockchip RV1126B on the base disc · 5 V rail on the base disc · Power, about 3 W (est.)

1. 3 Nov 2026, 22:25LatestA plant buyer reading the CellOne page should see the signal tower as it will be sold: one board of our own running up the tower. Until now the 3D view, the parts list and the wiring still lit the bench parts (a Pi Zero, a camera module, a heat-camera board, a mic board, an analogue reader, LED sticks and a power board), so the page showed a prototype, not the product.

   • What we designed: CellOne rev T, the signal tower with our board inside, done the way CricketOne, AthleticsOne and RacketOne put their boards in. Every bench part comes out and nothing bought stays: the board does every job. The base disc lies on a new 3 mm aluminium floor plate that carries its heat to the machine's steel guard, with a pocket under each chip on its underside and a hole for the tower's M12 machine socket. The tower gets the two changes the board asked for: a 56 x 6 mm slot in every tier plate, so the lamp sections and the spine pass through, and a square floor hole for the M12 socket. The Wiring and Program sections now name our board: the RV1126B reads the camera, heat chip, mic, motion sensor and the four isolated tier inputs, and drives the lamps and sounder. See /products/cellone/ and /build/cellone-boards
   • How we checked it: every board part was checked in 3D against every tier, plate and window, with 0.3 mm clearance, and against the floor plate. One real fix came out: the camera looks 45 degrees down, and with its chip level with the window, its line of sight left the wall 14 mm below the window, so the lens holder and lens reached into the wall. The camera head moved up and in onto that line (centre 119 mm up), so the camera now looks out through the middle of its window with the lens 1.1 mm inside the wall. The riser flex grew 40 mm (the board is 712 mm unfolded), and the board code now checks the line of sight, the lens rim and the holder corners in 3D. The ten camera-view checks still pass; the assembly check shows no problems.
   • Every board re-run: the board code, the design reviews and the design packs for all seven boards. No new CricketOne decisions since the last update, so nothing new was carried to the other boards this time; CellOne's lesson matches the fit3d lesson RacketOne taught.
   • What is next: the same step for RoomOne (the thermostat plate) and DampOne (the fan grille ring), one product at a time.

   See it in 3DFull research and design

2. 3 Nov 2026, 21:05Every product page now shows our own board the way CricketOne does: in 3D, folded inside the real equipment, with every part clickable. CellOne (the machine signal tower) and RoomOne (the thermostat) still showed only a flat drawing, so a buyer could not see where the cameras, radar and air chips sit inside.

   • What we designed: 3D models of both boards for the board viewer. CellOne: the 672 mm rigid-flex spine folded up the 70 mm tower: the base disc on its aluminium floor plate with the RV1126B, memory, latched microSD and M12 machine socket; the riser and tamper tab up the wall; the colour camera head tilted 45 degrees down behind its window; the wall flex round to the heat head on the side wall; the mic tip at the mic holes; the spine up the centre through each tier plate, with a lamp section in each coloured tier and the sounder tab under the cap. RoomOne: the flat 128 x 98 board in the thermostat, room side to the screen, keys, radar, particle and tone windows, wall side with the radio, relays and wire terminal, and the air corner shown cut off by its L slot. Both product pages now show the 3D board (In the tower / In the thermostat, or laid flat) in place of the drawing, and both board pages open with it. See /build/cellone-boards and /build/roomone-boards
   • How we checked it: the models are generated from the same board code that KiCad opens, and a script checks that every CellOne part lies inside the 32 mm inner radius of the tower and below the cap. Every board was re-run in the same pass: AthleticsOne, RacketOne, CellOne, RoomOne, DampOne, ChillOne and CricketOne all place with no problems, every design review has 0 fail, KiCad design-rule checks are 0 on all seven, and the quote and design packs were rebuilt (DampOne's 3D model now shows its latched microSD card). No new CricketOne board decisions since the last update, so no new shared rules this time
   • What we learned: CellOne's placement code holds no part heights yet, so the 3D model lists them from the datasheets with the lens holder, M12 socket and sounder marked est.; the fold positions of its riser and heads come from the placement code and are set exactly in the next step, the board in the tower CAD
   • What is next: the Wiring and Program sections of AthleticsOne, RacketOne, CellOne, RoomOne and DampOne switched from the bench parts to the parts on our own boards, then each board fitted in its product CAD the way CricketOne's is

3. 3 Nov 2026, 18:06A plant fits CellOne to 5 to 60 machines at once, so every tower must be one board an assembly house makes and tests the same way, on the machine's own 24 V lead, with nothing plugged together inside.

   • What we designed: one board that runs up the whole tower. A 60 mm disc with the RV1126B chip, memory, Wi-Fi and the machine socket lies on an aluminium plate that passes its heat to the machine's steel guard. Flexible sections climb the wall to the colour camera chip and the heat-camera chip behind their windows and to the mic, and a spine up the centre carries one lamp section per tier and the sounder under the cap. It replaces our first sheet, which used a bought module, a camera cable, a harness and spring contacts. See /build/cellone-boards
   • How we checked it: the board is written as code and opened in KiCad (0 design-rule violations). It places 68 parts at their datasheet sizes and checks that each fits its section, nothing overlaps, the camera, mic and tamper switch sit at the tower design's heights, the flex paths have slack, and each lamp section stands inside its tier and passes through the plate slots. All checks pass
   • What we learned: our first sheet named the wrong version of the heat-camera chip (the narrow 55 degree lens). The board now takes the 110 degree version the tower's view checks use. The tower becomes one sealed unit with a slot in each tier's plate, which removes the spring contacts between tiers
   • What is next: the plain towers' socket pinouts, the camera chip's package drawing from the maker, and the next product's board, RoomOne

4. 3 Nov 2026, 17:18A plant fits CellOne to 5 to 60 machines at once, so every tower must be made, tested and set up the same way by an assembly house, on the machine's own 24 V lead, with no hobby boards, ribbons or adapters.

   • What we designed: the brain lies flat in the tower's base on the same RV1126B module as CricketOne, on an aluminium plate that passes its heat through the bracket screws to the machine's steel guard. Our camera board is fitted with a colour chip that already has a Linux driver; the heat camera chip and a digital mic sit on their own board; each lamp tier gets a small ring of LEDs. See /build/cellone-boards
   • What we learned and changed: the bench design ran a camera ribbon through the twisting joint between the base and the sensor tier. On our boards those two become one screwed unit, and only slow lamp lines cross the twist-on tiers, on doubled spring contacts. If the brain ever stops, a watchdog hands each lamp back to the machine's own line, exactly like a plain tower
   • How it was checked: board sizes from the tower CAD (Ø64 inside); every joint listed with its key and lock, including the lead's M12 pinout against the plain tower and the camera cable's contact side, the fault that shorted our test board; electronics about $186-249 a tower at 10 units and $103-133 at 1,000 (est.)
   • What is next: CricketOne's boards prove the module and software first; then the colour camera and heat chip on the development kit, and CellOne's rev A boards in February 2027 (est.)

5. 30 Oct 2026, 02:25Machines placed on the EU market from 20 January 2027 fall under the new EU Machinery Regulation, which asks that a connected device cannot corrupt the machine and that every intervention is recorded, with logs kept five years (UL, 2026). Since 11 September 2026 the EU Cyber Resilience Act also makes the maker of any connected product report an actively exploited flaw within 24 hours (Jones Day; European Commission). Meanwhile a clip-on lamp-state sensor now sells for $107.70 (Advantech store).

   • Market and rules check (DESIGN.md): the EU Machinery Regulation 2023/1230 Annex III 1.1.9 and 1.2.1 (from 20 January 2027), Cyber Resilience Act Article 14 reporting (since 11 September 2026), the RED cybersecurity act with EN 18031 (since 1 August 2025) and Advantech's $107.70 WISE-S100 lamp-state sensor, each with what it changes in CellOne (sources M1-M5)
   • The tower now signs its running software version and keeps a signed record of every update, setting change and tamper event for five years; call clips stay 14 days; a record aid, never a conformity claim
   • IEMI keeps a security contact, a written 24-hour reporting plan and a stated support period before the first EU sale; two new rule lines and updated security entries in equipment.json
   • No CAD change and no new part (the read-only tier-line inputs and the ATECC608 are already in the tower); still 7 calls, 5 alone and 2 assist; price kept at $790 per machine + $29/machine/month
   • Product page https://iemilabs.com/products/cellone/ gains two FAQs (EU machine and cyber rules, why not a $108 stack light sensor) and a records spec
   • Next: ask machine builders and plants in the phase 3 buyer review whether the change record is a reason to buy; the next run checks ChillOne

6. 29 Oct 2026, 01:58A small moulder or machine shop needs every machine to report its state, cycles and stop reasons, and to catch a cold heater band, a dial out of band or a full bin before it costs parts. Today they pay a monitoring vendor every month for this (Evocon $189-319 per machine a month, FourJaw £36-90, 2026 guides $30-150) and buy the signal tower separately (Banner TL70 wireless about $561).

   • Buyer check with sources: Evocon and FourJaw monitoring plans per machine a month, 2026 OEE cost guides (TeepTrak, Guidewheel), the Banner TL70 wireless tower at distributors
   • What we learned: monitoring is sold as a monthly software line and the tower is bought separately; nobody makes the tower itself the monitor, and our $29 a month sits at the bottom of the software range
   • Parts list prices checked on shop pages today: $309 per tower at qty 1 (the page said about $295); the Pi Zero 2 W is now $19.05 and the 24 V supply $23.95; the brain part number fixed to match the buy list
   • Cost and margin table in the design notes: about $354 at qty 1 and $260 at qty 100, a 55 % to 67 % margin (est.); price kept at $790 + $29 a month per machine
   • All 10 camera and heat-camera views in the CAD still pass; CAD review clean with no floating parts and no collisions
   • Product page: the first three FAQs answer why not a wireless tower or software, what it costs per machine, and that it is not a safety device; a power and size spec group
   • Next: three questions for plants in customer reviews (swap a working tower or only at refit, $29 against software plans, which call pays first), then ChillOne for food, cold chain and pharma

7. 28 Oct 2026, 10:25A small plant needs one thing on each machine that shows every run and stop with its reason, reads the panel dials, catches a failed heater band and warns at an open gate, without walking the floor. Machine monitoring costs about $125 to $150 per machine per month (Guidewheel, MachineMetrics), and IEC 60204-1 already puts a signal tower on every machine.

   • Market check: who buys one product per machine (moulders, machine shops and formers), what they pay today for machine monitoring, dial readers, heat sensors and wireless tower transmitters, and the IEC 60204-1 and NFPA 79 lamp rules; sources in DESIGN.md
   • New CAD: the machine's Ø70 x 446 mm signal tower with a Raspberry Pi Zero 2 W brain, a lamp-line reader, a cycle sensor, a secure element, a tamper switch and a 24 V supply in the base, a cell camera, a heat camera and a mic in a sensor tier, a light in each of the four lamp tiers and a tone in the cap; 13/13 parts fit from datasheets, 10 camera views checked, size and red-on-top checked, no collisions, no floating parts
   • equipment.json: IEC 60204-1 10.3, NFPA 79, OSHA 1910.212 (the machine's guards untouched), same size and lead, IP65, staff notice; 7 calls (5 alone), 4 impact cases and every security key
   • idea.json cell plan, integration.json (6 parts, 5 app screens with a mode for when no supervisor is on the floor), bom.csv (about $295 a tower), buy.json with 10 key parts
   • New product page at /products/cellone/ in Manufacturing: $790 + $29/machine/month against about $1,703 + $47/month bought separately (est.); folds MachineState; starter panels, compressors, motor bearings and part inspection stay with their own zones; next: F11 Food, cold chain and pharma

Smart equipment · legal on the field

CellOne is the machine signal tower (stack light), made smart

It replaces the machine's existing Ø70 signal tower (for example a WERMA KombiSIGN 71 or a Patlite LR7), on the same bracket, the same three M5 holes and the same 8-pin 24 V lead from the machine controller, with every part built in. Everything inside the Ø70 tower: Raspberry Pi Zero 2 W, cell camera, heat camera, mic, tier-line reader, cycle sensor, four lamp sticks, tone, secure element, tamper switch and the 24 V to 5 V supply. About +90 g over a plain 5-element tower (est.); no pole camera, panel box, motor puck or light box.
