Selected work

Projects, described as far as we are allowed to.

Most of what we build carries a customer's brand and a confidentiality agreement. These are anonymised on purpose — the same discretion applies to your project.

They asked for a cheaper copy. They got a better machine — for less.

A customer arrived with a competitor's dental cautery unit and a two-word brief: cheaper, lighter. What left the workshop was a metal-bodied machine with more power, a new controller and a wireless footpedal — and it cost twenty percent less than the box they brought in.

Copying a competitor's unit is the most common request we get and usually the least interesting thing to build. The machine they brought in worked. It was also built around a controller doing the minimum, in an enclosure that felt like it, carrying parts that no longer earned their place.

20% cheaper

than the unit they arrived with

Every change above landed while the cost went down, not up. That is the whole engineering argument: the savings from taking parts out more than paid for putting better ones in.

  1. 01

    Subtraction first

    Before adding anything we took things out. Every part that existed because of how the original had been designed, rather than because the machine needed it, came out. That is where the money came from — not cheaper components, fewer of them.

  2. 02

    A metal body

    The enclosure was rebuilt in metal. It is the part a dentist handles every day, and the part that decides whether a machine reads as equipment or as a toy.

  3. 03

    A controller worth the name

    The original control board did the minimum. Its replacement gave us headroom for the interface, the power range and everything that followed.

  4. 04

    Feather-touch front panel

    Buttons that answer to a touch rather than a press. In a surgery, with gloves on, that is not a styling decision.

  5. 05

    More output, not less

    The power range went up — the opposite of what a cost-reduction exercise normally produces.

  6. 06

    A wireless footpedal

    The pedal lost its cable. It is the change that most alters how the machine is used, because the cord on a footpedal is the thing always in the way.

The brief was to copy something cheaply. What we argued instead was that the same money, spent differently, buys a better machine. Their name is the one on the front of it.

PI-24-A

Electrosurgery

Dental device brand

Dental cautery unit, rebuilt from a competitor's

A dental brand arrived with a competitor's cautery unit and asked for it cheaper. It left as a different machine.

What we did

  • Output stage design and RF tuning
  • Control board and firmware
  • Front panel, enclosure and assembly

PI-23-B

Automotive safety

In-house product

Crash detection and emergency call-out

Detect a vehicle impact reliably enough to place an emergency call automatically, without firing on potholes and speed breakers.

What we did

  • High-g sensing and event classification
  • Cellular back-haul and call-out logic
  • Field validation against real impact data

PI-25-C

Test and measurement

Automotive testing programme

High-g capture and signal validation rig

Validate that a device under test reports impact signals correctly, by injecting known waveforms and comparing what comes back.

What we did

  • Waveform injection and capture tooling
  • Automated compare and pass / fail reporting
  • Bench instrumentation and harnessing

PI-22-D

Medical devices

In-house development

Wireless surgical cautery instrument

Remove the cable from a cautery handpiece without losing the power or the control the surgeon expects.

What we did

  • Handpiece electronics and power design
  • Control board and firmware
  • Prototype build and bench testing

Why it reads like this

Discretion is the default.

Every project above is real and none of them names a customer. That is the arrangement most of our customers need — and the reason they can put their brand on something we built.

A device brand’s advantage is that the market believes the product is theirs. Publishing a client list would sell that advantage for a line on our website.

It is also why you will not find product photographs anywhere on this site. The finished units are our customers’ products, usually before they are ready to show them. That restraint is the service, not an oversight.

What we will share on a call

  • Technical detail on how a comparable problem was solved
  • What went wrong first, and what the fix cost
  • A reference, where that customer has agreed to give one
  • Units on the bench, if you visit

Your project would be described like this too.

Anonymised by default, named only if you say so. That is not modesty — it is the arrangement our customers need.
