Hardware prototyping that ends with a unit you can hold.
Parts selection, breadboard, custom board, enclosure, assembly, bring-up and test. Roughly 80% of prototype categories are covered in-house, hands-on, so an iteration is a walk to the bench instead of an email chain with three vendors. When something genuinely needs an outside specialist, we name the partner rather than pretend.
Free meeting · Free consultation · Free demo — for every project, every client.
You pay only when you say 'build it'. NDA-first if you want it — your idea stays yours.
The sentences we hear most.
Written the way clients say them on the first call, not the way a brochure would.
“I have a clear idea and no idea whether it can be built.”
“Three vendors quoted us and every quote assumes something different.”
“Our prototype runs on a bench supply and dies on a battery.”
“The parts we designed around are now unobtainable.”
“The printed case looked perfect until we tried to fit the board inside it.”
“We need ten working units for a trade show and we have a breadboard.”
What actually lands in your hands.
Listed before the work starts, so finished is never a matter of opinion.
- A working prototype unit — assembled, powered and demonstrated, not rendered.
- Bill of materials with real distributor links, prices at your quantity, and second sources.
- Enclosure CAD in STEP plus the editable source, with print or machining notes.
- Wiring and assembly documentation: photos, pinouts, and the fiddly details that only appear the second time.
- Test results: what was measured, on what unit, with which instrument.
- A feasibility and risk note, including what breaks at a hundred units that did not at ten.
- Cost-per-unit estimate at three quantities, with every assumption written down.
- The route to production: what needs redesign, tooling or certification before manufacturing.
Everything above is yours: code, files and accounts are assigned to you and delivered in your repository. You could replace us tomorrow and still ship.
How we build it.
Five steps. The first three cost nothing, and the third is the one that decides everything.
Meet
FREEA 20-minute call. You describe the problem; we ask the questions that matter.
Consult
FREEFeasibility, approach, and an honest effort estimate — from an engineer, not a sales rep.
Demo
FREEWe build a working demo of your idea, so you see how we work before you commit.
What the free demo looks like hereBring the idea and we come back with a feasibility teardown: how we would build it, a CAD sketch of the form, the actual parts we would use with today's availability and price, and an honest list of what could sink it.
Build
You liked the demo. We scope it, quote it, and build it.
Ship & support
Deployment, handover, and support after launch.
You pay only when you say 'build it'.
What the work is done in.
Grouped by where each tool sits in the build. Labels, not a logo wall.

Work in this service.
Your project could be the flagship here — and it starts free.
We publish a case study only once the client has approved what it says and the numbers in it are ours to show. For Hardware Prototyping that shelf is still empty — and we would rather show you nothing than show you somebody else's screenshot. The free demo is how the first one gets written.
Questions that decide whether a project starts.
Cost, timeline, ownership, what happens after delivery — and exactly what the free demo includes for this service.
