From problem to product.

Bring us a problem or an idea. We listen until we understand it, write down what the product must do, and design and build it to do that job reliably.

Landing at speed

A landing marker that lights up for an event camera, so a drone can land fast and precisely. In simulation it finds the pad hundreds of times a second, at 2 m/s.

A battery board for big drone packs

Watches every cell in packs of 6 to 12 cells and reports each one to the flight controller. It never cuts the power in flight.

A compact battery board that measures current

For packs of 3 to 8 cells, with current measured on the board up to 100 A, in a case designed around its heat path.

A carrier board for long-range drone radios

Runs straight from the drone’s battery, plugs into the connectors drones already use, and lets the radio be swapped without soldering.

A backup link that is flying today

A long-range radio add-on for the Raspberry Pi, a small computer. It flies as the backup link on a client’s drone.

01 / How we think

The problem writes the spec.

A specification is the list of what a product must do, how well it must do it, and where it has to work. We write it from your problem, one line at a time, and you sign it off before any design starts.

From then on, the specification is the yardstick. Every design choice is checked against it, and every line gets a test.

When something needs to change, the specification changes first, so you can see what the change affects before anyone redraws a board.

Problem

“Our drones lose sight of the landing pad when they come in fast.”

02 / Worked examples

Each one started as a problem.

01

Landing at speed

Problem
A drone coming in fast loses sight of its landing pad. GPS only gets it within a few metres, and the camera image blurs.
What it had to do
See the pad hundreds of times a second, in bright sun or near dark, and know where it is to about a centimetre.
What we built
An event camera and a landing marker that lights up for it. We tested the whole system in simulation before buying a single part.

02

A battery that tells the truth

Problem
A drone battery is a stack of cells, and the weakest cell decides when the flight ends. Most drones only see the total voltage, so a weak cell stays hidden until it is too late.
What it had to do
Report every cell to the drone’s flight controller (the computer that flies it), and never cut the power in flight. The aircraft decides when to land.
What we built
Two battery boards. MODB-BB for packs of 6 to 12 cells, and MODB-SB for packs of 3 to 8 cells.

03

A link that reaches

Problem
Long-range radio modules come as bare parts, so each drone team builds its own board to power and connect one.
What it had to do
Run straight from the drone’s battery, plug into the connectors drones already use, and let the radio be swapped without soldering.
What we built
MODL-Core, a carrier board for long-range drone radios.

03 / How we make it reliable

Small checks, made early.

A fault found on screen takes minutes to fix. Found in a finished product, it can mean reworking every unit. So we look for faults early, and we write down what we find.

01

We simulate before we spend

Before we bought a single part for the landing system, we built it in software: camera, marker, lighting and movement. The simulation found three design faults. In one, a marker mounted back to front made the system fail without any warning.

02

Six checks before any board is ordered

Every circuit board goes through six checks between a finished drawing and an order. On one of our battery boards, the second check found a power terminal sold online as 135 A. The maker’s own drawing said 80 A. We changed it before anything was made.

03

Tested line by line

Every line of the specification has a test. You get the report, with each result next to the line it checks.

04

Handed over

The specification, design files, test reports and documents for your project are handed to you at the end.
