Why us
Custom projects, for companies of every size.
Custom engineering and production are what we have done all our working life. Start-ups, manufacturers and large companies alike need devices that simply aren't on the shelf — a controller for a machine, a gateway for a fleet of inverters, a sensor that sees what others miss. Whatever the size of your company or of your project, you get a dedicated team that builds exactly what you need. One team designs the hardware and writes the software, so nothing gets lost between suppliers.
- 01One point of contact, idea to production
The same engineers draw the schematic, write the firmware, build the server and the app — and answer your call afterwards.
- 02Hardware and software designed together
The board is designed for the software it will run, and the software knows the board. Fewer surprises, faster debugging.
- 03From the first prototype to series production
Boards designed for automated assembly, production test stations, programming tools, serial-number labels and test records for every unit.
- 04Built to keep running
Watchdogs, safe fallback states, remote firmware updates and monitoring — devices that recover on their own in the field.
What we do
Anything in electronics. And the software around it.
A selection of what we design, build and run every day. Need something that isn't listed here? Ask us — custom work is what we do.
Embedded firmware
ESP32 (S3, P4), STM32 down to bare-metal register level, Microchip PIC 8/16/32-bit. Over-the-air updates, signed firmware, watchdog recovery, production test modes.
Industrial connectivity
Fieldbuses and networks that talk to the equipment you already own — meters, inverters, PLCs, sensors and the cloud.
Edge AI & machine learning
Neural networks trained on raw sensor signals and squeezed to run on the microcontroller itself — classifiers of a few kilobytes that decide on the device, without the cloud.
Measurement & signal processing
Precision multi-channel energy metering, pressure, radar, time-of-flight, pyroelectric and UWB sensing. Filtering, DSP, Kalman tracking, software-defined radio.
Cloud & IoT platforms
Multi-tenant platforms with real-time dashboards, alerts and PDF/CSV reports, MQTT brokers and device management — running on infrastructure we operate ourselves.
Web & mobile apps
Web apps and dashboards, web interfaces served by the device itself, and native Android apps with push alarms, prepared for Google Play.
AI-powered software
Language-model assistants built into our platforms: they read documents, lab results and sensor data, and help specialists reach a decision faster.
Energy systems
Solar and hybrid inverters, battery management systems, energy meters, heat pumps, export limiting and automated UPS / battery testing.
Building & industrial automation
I/O controllers, HVAC and fan-coil control, building management, wireless zone gateways, alarm and safety systems.
Test automation & production
Automated bench tests driving lab instruments, production programming and test stations, labels and traceability for every unit: serial number, test results and firmware version, recorded automatically.
Enclosures & 3D
3D-printed enclosures designed in code and checked against the real board for fit and printability — plus interactive 3D presentations like the ones on this page.
PROJECT 01 · ENERGY & FIELDBUS
7-channel isolated CAN + RS-485 module for an ESP32-P4 controller
One compact stack that speaks to inverters, batteries, meters and chargers at the same time — every channel galvanically isolated, so nothing in the installation shares a ground it shouldn't.
Loading the 3D model…
7isolated channels:
3 × CAN · 4 × RS-485
3 × CAN · 4 × RS-485
0shared grounds between the buses — isolated power on every channel
400MHzdual-core RISC-V ESP32-P4: Ethernet, Wi-Fi 6, USB
1wide-range DC input, protected — also powers the controller
Each channel is its own island — transceiver with integrated isolated supply, so a fault or ground shift on one bus never reaches the others.
120 Ω termination per channel, set with a jumper on site — no soldering.
Pluggable 3.5 mm screw terminals on one edge — the field wiring stays connected when the module is swapped.
Protected power input: reverse-polarity proof, fused, surge-suppressed; an on-board switching regulator feeds the whole stack.
Stacks on a standard 40-pin header (Raspberry Pi 4 format controller board) with printed spacers and a 3D-printed enclosure.
Designed for machine assembly: placement and parts files generated and checked automatically.
What can you build with it? A realistic brainstorm.
Ideas we can deliver on this platformMonitor
Inverter monitoring, second by second
PV, battery, grid and load data from hybrid and solar inverters over Modbus — logged locally, sent to the cloud, alarms on your phone.
Control
Inverter control
Set charge / discharge power, operating modes, export limits and time-of-use schedules. Zero-export and self-consumption control using a grid meter.
Integrate
Battery bridge
Read a lithium BMS over CAN or RS-485 and present it to the inverter in the protocol the inverter understands — use batteries it doesn't support natively.
Combine
Several batteries, different brands or chemistries, one inverter
The module reads every BMS, computes safe combined charge and discharge limits and a consistent state of charge, and reports one well-behaved battery to the inverter — while protecting the weakest pack.
Scale
Several inverters, no ground loops
Seven separate buses at once, each isolated: coordinate multiple inverters, meters and battery stacks from one controller.
Optimise
Solar surplus & peak shaving
Drive EV chargers, heat pumps and boilers from the surplus; cap peak demand by shifting loads and battery power.
Translate
Protocol gateway
CAN devices to Modbus TCP or MQTT; legacy RS-485 instruments to Ethernet and the cloud — without replacing them.
Diagnose
Commissioning & bus analyser
Capture and decode traffic on every bus during installation, record faults for later analysis.
Display
Local touchscreen HMI
The controller drives MIPI displays: status, energy flows and settings right on the cabinet door.
Learn
Edge intelligence for energy
On-device anomaly detection on battery and inverter data, short-term PV forecasting, and local decisions that keep the installation safe when the internet is down.

PROJECT 03 · ENERGY METERING
15-channel energy meter — three phases, fifteen circuits, one board
Sub-metering for distribution boards: one board measures three phase voltages and fifteen circuits at the same instant, keeps the measurement galvanically isolated from the network side and reports over Ethernet or Wi-Fi.
Loading the 3D model…
18synchronous channels: 3 voltages + 15 currents
6400samples per second on every channel, all at once
2processors: PIC32MZ measures, ESP32 communicates
1isolation barrier between the mains side and the network
Three 24-bit metering ADCs on one shared clock — voltage and current are sampled at exactly the same instant, so power is computed from truly simultaneous values.
Per circuit: RMS current, active power, imported and exported energy. Per phase: RMS voltage and frequency.
Real-time DSP on a PIC32MZ: filtering and RMS integration in the sampling interrupt, hand-optimised where every microsecond counts.
Energy counters in FRAM, saved periodically and on demand — they survive power cuts. Automatic phase calibration.
Current transformers up to 120 A on pluggable terminals, three-phase + neutral voltage input, separate low-voltage supply.
Network side on ESP32: Modbus TCP (several clients), MQTT with JSON, built-in web interface, over-the-air updates — Ethernet or Wi-Fi.

BaroAware — intrusion detection from air pressure
Patent pendingWhen a door or window opens anywhere in a building, the air pressure inside changes everywhere at once. BaroAware measures that tiny change and recognises it with a neural network that runs on the device itself.
- Sees an opening anywhere in the connected air volume — no line of sight, no camera, no microphone
- Tells a real opening from wind and ventilation by the shape of the signal — learned from real recordings, day and night, in wind and rain
- The CNN runs entirely on the microcontroller; detection needs no cloud
- Android app with push alarms, arm / disarm, event log and supervision if a sensor goes silent
- Ethernet or Wi-Fi + LoRa editions — and a new Fusion edition with a 60 GHz radar on the same core
- An extra layer of protection that works alongside an existing alarm system
Edge AI · CNN · machine learning
We teach small sensors to see what their datasheet can't.
Most sensors give you a finished verdict — and the verdict fails exactly in the hard cases. We go one level deeper: we read the raw signal and train a compact neural network that runs on the device itself.
Read the raw signal, not the sensor's built-in decision.
Build a labelled dataset on the bench and in the field, including the hard cases.
Train a compact CNN on maps of the signal over time.
Quantize to INT8 — models of a few kilobytes that fit next to the firmware.
Verify on the real device, with measured results in real conditions.
PressureDoors & windows from tiny air-pressure pulses
Openings anywhere in a building, one sensor per floor — now a product: BaroAware.
PyroelectricHuman vs. pet vs. heater
Raw PIR signals classified to cut false alarms.
Time-of-flightPresence from signal coherence
A 4 KB on-device network where distance alone gives up.
60 GHz radarBreathing & presence
Raw radar data for stillness and absence detection.
UWBPositioning in metal-heavy plants
Telling clean line-of-sight from reflections to stabilise indoor tracking.
How we work
From a conversation to devices in the field.
Talk
What it must do, where it will run, how many units, the budget — and you get a clear plan for getting there.
Prototype
Schematic, board, first firmware and a working demo — usually the fastest way to settle open questions.
Validate
Bench tests, edge cases, a pilot on site. Measurements, not assumptions.
Produce
Series production: machine-assembled boards, test stations, enclosures, labels and documentation — at the volume you need.
Support
Remote updates, monitoring and changes when your needs change.
Engineering, amplified by AI. We combine decades of hands-on electronics experience with AI-assisted design review, verification and documentation. Every check is automated where it can be — and every result is confirmed on real hardware.
