LineCell

How it fits together

LineCell, part by part

Scroll or tap a part. Press “See the 3D CAD design” to watch the model, built from our CAD, light each part up and show how it connects.

1. 01

   The whole LineCell

   The light-box camera checks every part; the head on the machine reads its state, motor, air, panel and dials; one hub joins both.

2. 02Brain

   Edge Hub: Raspberry Pi 5 + AI HAT+

   The brain, in a separate hub box (not shown): it runs the linecell-hub program

    All connected

    8 key parts, one program, and your phone

The idea

One kit at a moulding machine that checks every part and knows what the press was doing when it was made

How the parts connect

LineCell, 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.

The program

What controls LineCell

head.on('line', async (line) => {
  const msg = parse(line);                       // from the ESP32-S3 head
  if (msg.type === 'TRIG') {
    const roi = cropToFiducials(await camera.grab());
    const verdict = decide(await hailo.embed(tile(roi)));
    head.write(`RES ${msg.n} ${verdict}
`);      // reject / lamps
    cell.add({ verdict, ...machine.now() });     // tagged with state, oil, air
  } else machine.update(msg);                     // state, amps, psi, dials, heat
  for (const f of cellReport(cell.window()).flags) alert(f);
  if (due('SUM')) mqtt.publish(`${topic}/cell`, summary(cell, machine));
});

Pricing

Target pricing. Bought separately for one cell, QualityCheck Inspect ($3,499 + $399/mo) and PlantNode ($1,190 + $39/mo plus a $399 LoRa gateway) add up to $5,088 + $438/month. Parts cost about $1,420 per cell (est.). Fitting inside a machine cabinet must be done by a qualified electrician.

Indicative launch pricing in USD, excluding taxes and shipping. Final pricing is confirmed before any balance is charged.

1. 29 Oct 2026, 09:25LatestOwners and QC leads at 10 to 200 person moulders check parts by eye and learn about press trouble from the scrap bin; vision cameras cost $4,500 to $9,450 each and monitoring services start near $15,000 a year for 10 machines, and neither ties a bad part to what the press was doing (LineCell DESIGN.md market check).

   • Drawn idea plan (idea.json): a moulding cell from above with the 120-tonne press, its mould and clamp, injection unit, pump, cabinet, stack light and air drop, and the inspection bench on the operator side; pins for the hub and part camera at the bench, the cell head on the cabinet, the stack-light clip, the pump motor puck, the air pressure on the air drop, the cabinet heat eye and the gauge camera
   • The product picture is now this drawn plan instead of the plain fallback card; drawn from the design notes, not the CAD
   • What the plan keeps from the market work: monitoring vendors watch the press and vision vendors watch the parts, and no small-shop product found does both at one cell, so the plan shows both on one floor
   • Next: more drawn plans for catalogue products that still show the fallback card (oxycart, paceroll), then close-out C5 (buyer review prep for sports) from 12:00

2. 27 Oct 2026, 15:05A small moulder checks parts by eye and learns about machine trouble from the scrap bin: start-up after a stop is when most scrap is made, and inspection results are only useful when they can be tied back to the press (Plastics Technology; Fabrico on start-up rejects in moulding). Monitoring kits such as Guidewheel watch the press but not the parts, and vision cameras such as Overview AI watch the parts but not the press. Our own two products for one cell cost $5,088 + $438 a month with two apps that never meet.

   • New product LineCell: one Edge Hub at the inspection bench checks every part and runs every PlantNode job, so each bad part comes with what the machine was doing when it was made
   • The PlantNode head on the machine cabinet now also does the QualityCheck I/O pod job: one new head base with two 24 V terminal windows, one USB lead to the hub
   • Reused CAD parts unchanged: the QualityCheck camera mount, LED ring holder and diffuser, part nest, panel clip and photo-eye bracket, and the PlantNode lid, motor puck, thermal eye, stack-light clip and tag carrier. 14 printed parts, each one solid, every bought part fits
   • 3D view: a moulding machine with its cabinet, stack light, pump motor, dials and air drop, and the inspection bench with the light box, hub and screen beside it, at real size
   • Program: 5 new checks pass, such as scrap counted after a restart and a reject spike tagged with the oil temperature or the air pressure
   • Dropped: the QualityCheck I/O pod, the PlantNode LoRa radio, its $399 gateway and its 5 V cabinet supply; the compressor-wide idle-air figure stays with PlantNode, LineCell measures the cell's own air leak
   • Hardware: parts about $1,420 a cell (est.); priced $3,990 + $349 a month against $5,088 + $438 a month for the two separately; product page, parts list, how-it-works and design notes added
