Selected work

Open Weed Locator v3.0:
AI precision agriculture.

A mixed-signal board redesign to consolidate a field robot's entire electronics onto one compact PCB, running advanced AI crop detection.

Farm-proof design

The Open Weed Locator (OWL) is an open-source precision-agriculture platform, linked to the Noktura AI ecosystem for agricultural data, which detects weeds in real time for targeted spot-spraying. Noktura asked us to redesign the existing system to incorporate several components on one small, field-rugged PCB.

We delivered a mixed-signal design in a compact footprint, integrating compute, PCIe, cellular, Wi-Fi, high-res camera, Ethernet and the sprayer solenoid drivers. The new product withstands temperature extremes, rough handling and noisy agricultural power supplies, and is designed to be easy to maintain.

How an engagement runs

Agile, flexible, iterative design.

Every engagement follows a documented sequence, aligned with the Agile methodology. Our process adapts to your roadmap and method of work, supporting your ISO 9001 / AS9100 workflows if required.

01 · Scope

Define the problem

Starting with a free 30-minute consultation, we'll write a scope covering the assumptions and your goals. The project will be broken down into phases, with a fixed estimate cost for each. Each phase is about 3-4 weeks of work.

02 · Design

Design iteratively

At the beginning of each phase, we carefully review and agree the scope. We'll then start the technical work, designing the product schematic, RF, PCB and firmware in industry-standard tools such as KiCad and Sonnet.

03 · Prove

Measure, don't assume

We meet with you every week, or on a cadence you determine, until the phase is complete. This ensures our work is closely aligned with your requirements.

04 · Hand over

Documented handover

You receive a handover at the end of each phase, ready for the next phase on your timeline. Design-and-source escrow can also be arranged through an independent UK escrow agent, so continuity is assured.

Where we work

Who we work for.

S/01

Aerospace & Defence

Antenna design and qualification for aviation and space, supporting some of the largest names in aerospace. We align with your AS9100 workflows.

S/02

IoT & Connected Products

We take your connected product concept to prototype, integration testing, and production – so it ships on time. We handle antenna integration in-house, plus Radio Equipment Directive (RED) and UKCA pre-compliance.

S/03

Industrial

We build ruggedised wireless modules, repair and troubleshoot critical hardware, and design replacement parts – allowing your equipment to last longer.

S/04

Startups & SMEs

Got an innovative idea? We are the outsourced RF and hardware team for agile startups. We take your idea from concept to prototype, and help you navigate mass production as you scale. Your IP remains protected throughout.
