electronic product design for startups and SMEs
We design and build products with electronics inside, for founders, startups and established businesses. Electronics, firmware, enclosure and app, all from one team, built and tested in our London lab. You keep all the IP.

Recent work for TBKFiT, SKN Systems and Orasonic.
Fiddlie took BoKi4 from a sketch to a boxed product for sale. One team handled the industrial design, electronics, firmware and app, so nothing fell through the gaps between suppliers, and they're still who we call for manufacturing. If you're building a hardware product, talk to them first.

Our engineers are named inventors on patent filings for about half the products we've delivered, with the IP assigned to each client.
case study: TBKFiT
from sketch to production: BoKi4
Four-limb motion and heart-rate tracking for combat sport. We developed BoKi4 for TBKFiT from the first sketch, and now look after its mass manufacture and the TBKFiT app.
01
concept sketch
Industrial design starts on paper: a sensor module that clips into an ergonomic, adjustable carrier.
02
proof of concept
A quick 3D-printed carrier and module housing, to test fit and comfort on the wrist before anything is tooled.
03
electronics
The sensor module's circuit board and firmware, designed by one team so the hardware and code fit together.
04
production design
The finished design, refined for manufacturing at volume.
05
packaging and launch
Retail packaging with a moulded insert, CE and UKCA marked and ready for sale.
your product, next
Bring a sketch, a prototype or just the idea. We'll scope the first stage with you on a call, under NDA.

pcb design
We design boards to be built. Parts are checked for availability at your volumes, and the layout is done with assembly in mind from the first draft. Your manufacturer can quote it and build it, with no redesign needed.
embedded systems & firmware
Embedded firmware written by the same team that designs your hardware, so nothing gets lost between board and code. Low-power operation, sensor integration and connectivity, tested on real boards in our lab.
power management
A battery that lasts. Charging that is safe. A supply that stays steady when the load jumps. And when your product needs to sip power, we design for ultra-low power from the start.
testing & compliance
We test on real hardware and go looking for the weak points before your customers find them. Certification is planned in early, so there are no late surprises.
industrial design & enclosures
Enclosures designed alongside the electronics, with CAD, 3D-printed and CNC prototypes made in-house, so the board and the housing fit first time.
companion apps
Mobile apps that talk to your device, built by the same team as the firmware, as we did with the TBKFiT app for BoKi4.
how we work
Our lab has automated PCB pick and place, conveyor reflow and signal analysis equipment, so we build the early prototypes ourselves, quickly and accurately. For high-volume production, EMC testing and certification support, we work with a vetted network of specialist manufacturers.
in-house capability
PCB design, embedded systems, prototyping and test, all under one roof. No handoffs, nothing lost in translation, faster iteration.
manufacture-ready output
Designed for production from day one. IPC-compliant, BOM-optimised, and ready for your contract manufacturer to build without rework.
protected IP, transparent terms
NDA from the first conversation. Fixed-price milestones, paid in stages. On completion, the IP is all yours.
our process
1. initial meeting
Meet with one of our engineers to discuss your project under NDA.
2. free fixed quote
We prepare a proposal with payments spread out as we deliver.
3. project kick-off
We sit down together and agree exactly what we're building.
4. prototyping
We build prototypes, test them with you, and refine the design each round.
5. production
We produce pre-production units for investor demos, field trials or regulatory testing.
6. completion
Handover of produced demo units and all generated IP.
