Boards and parts, checked before they’re made.

We lay out circuit boards for wearables and small devices, and design parts around the loads they carry. You get files ready for the fab or the printer.

Hardware

What we design and build.

Every board goes through a clean design-rule check, with each part checked against supplier stock. Every mechanical part is strength-checked on its load cases, then checked again after the cut.

Circuit boards

Multi-board electronics for wearables and small devices. We take it from schematic through placement and routing to a clean design-rule check, and hand over fab-ready files.

Prompt to CAD

Our own design tool. A brief goes in and cut-ready files come out, checked by finite-element analysis against every load case in the brief. A person reviews every design before anything is made.

Enclosures

Housings and stands for small devices. THE ORB is ours: designed and assembled in Brisbane, with its first prototype 3D-printed.

Prototypes on the bench

Printed and assembled here, with the printer wired into the same line as the design tool. The laptop stand below is in daily use. The engine mount is a design study.

Prompt to CAD

Two parts, made 41 to 48% lighter and checked again after the cut.

Two parts from Prompt to CAD, the design tool we built for ourselves. A brief goes in. Cut-ready files come out, checked against every load case in the brief.

A go-kart engine mount, 48% lighter.

One side plate of the cradle for a 16 kg kart engine, cut from 8 mm 6061-T6 aluminium. Bumps, a clutch grab and hard braking were each checked. Material that carried no load came out. Then the cut part was checked again, every load case, before the files were released. Brief to cut-ready STEP file in under nine minutes.

A design study: in-plane loads only, and no substitute for a physical test.

A cooling wedge for a 14-inch MacBook Pro. Five load cases set the shape, 41% of the plate came out, the cut part was checked again before printing, and the printer on the bench is wired into the same line. Tools that didn’t know each other, made to work as one.

Parts made to fit

The tab that holds the headlight snapped off. We make a new tab.

A snapped mounting lug can leave a headlight that won’t bolt in. We draw a replacement lug in SolidWorks for that housing and print it. There are bolt-on and weld-in designs.

A black printed repair lug with a metal threaded insert and a bolt, fitted to the back of a Mercedes GLC headlight housing, with a steel rule against it.
A printed bolt-on lug with a metal threaded insert, on a Mercedes GLC (X253) headlight.

Lugs drawn for six models.

Mercedes C-Class (W205), GLC (X253), A-Class (W177), CLA (C118) and B-Class (W247), plus a Lamborghini Huracán. Each lug is drawn for its own housing. For the A-Class and CLA there’s also an alignment tool, drawn to line the new lug up.

Renders from the CAD files.

  • Render of a ribbed round lug with a threaded centre on a long base with two clip eyes.

    GLC (X253), lower lug

  • Render of an angled upper lug with a ribbed threaded boss and a mounting foot.

    GLC (X253), upper lug

  • Render of a bolt-on upper lug with a threaded boss and three fixing eyes.

    B-Class (W247), upper, bolt-on

  • Render of a triangular bolt-on plate with two fixing holes and a threaded boss.

    CLA (C118), bolt-on

  • Render of a ribbed upper lug with a threaded centre and a welding tab.

    C-Class (W205), upper, weld-in

  • Render of a curved side mount with a lattice-ribbed face.

Device projects

Most device projects break where one team hands over to the next.

The usual setup is three teams, with an integration phase bolted on the end. Hardware slips, so firmware stalls. Firmware changes an interface, so the app starts over. That’s where the schedule goes.

Early is cheap. Deciding the seams now costs a conversation. Deciding them after the board is made costs a respin.

Every interface between owners is a place where a change on one side quietly breaks the other.

Whoever picks up a layer last inherits every assumption the others made.

No integration phase

Our team holds all five layers, from the board to the cloud, so nothing gets lost in a handoff. When the firmware changes an interface, the people who changed it fix the app as well.

Where will your device project break?

Six questions, about a minute. You get a seam count, the three risks we would look at first, and which of our four fixed-price offers fits. Nothing is sent anywhere unless you choose to send it.
