Industrial control
PLC and DCS integration with Siemens, Honeywell, Emerson. Greenfield commissioning, rewrites, retrofits.
MelDev
We pave the way for turning smart ideas into reality.
Real-time control systems, custom electronics, and software for industrial and automotive clients. From the first sketch to the production line.
MelDev AB is an automation and product-engineering shop. We design control systems that run factories, write the software that ties them together, and build the hardware when nothing off-the-shelf will do.
PLC and DCS integration with Siemens, Honeywell, Emerson. Greenfield commissioning, rewrites, retrofits.
From schematic to assembled PCB. Signal conditioning, peak-and-hold drivers, embedded firmware.
C# / Java backends, iOS & Android apps, OPC / Modbus / Profibus servers, dashboards, databases.
MelDev is led by Robin Melin — process & control engineer at Honeywell from 2006 to 2018, where he worked as a Lead Engineer on pulp & paper, refinery and quality-control projects across Europe. He left in 2018 to run MelDev AB full-time.
Started on the floor as an instrument technician at Selek AB, Hitab AB, and as process engineer at StoraEnso Fors — while finishing ABB Industrial HighSchool on the industrial-process track with extra programming courses A through E and a heavy process-control load.
Joined Honeywell AB in 2006 as Design Engineer in Falun, moved to Mölndal in 2008 as System Engineer working on Experion DCS and Experion MX (formerly DaVinci) QCS, then took the Lead Engineer chair in 2015. National and international rollouts until 2018 — pulp & paper, refining, quality control.
MelDev AB was founded in 2018. Since then: 40+ rollouts in pulp & paper and refining across Europe, plus the bench hardware, automotive electronics, motion VR rigs, and the games and apps that came out of them.
A few of the things that left the bench. Click any card for detail; embedded videos are pulled from YouTube.
Custom PCB plus the control software that runs it. Drop-in test rig for fuel-system QA.
User-programmable industrial relay controller. Timers, counters, sequenced outputs, all from a touch UI.
Integrated GPS nav for land and sea, Bluetooth telemetry, real-time engine monitoring.
The dash on a Yamaha F100 outboard — trim, RPM, engine temp.
Pitch / roll / yaw simulator chair for virtual-reality content. Hardware + driver software.
Driving a virtual rollercoaster on the chair — full 3 DOF.
XYZ drill-angle measurement — operator never has to climb out of the cab to check angle.
Custom CNC intake manifold for a BBC, designed to fit a tight bay. Full 3D model with throttle simulation.
Limits injector current — peak to open, hold to keep open. Twelve channels, one box.
Shipped product, not portfolio shots. A motion-aware powerboat racer on PC and iOS, and a native retail / stock-management app with barcode & QR scanning.
Real ocean physics.
At its edge for PC.
Built in-house from the ground up. Released on Steam in May 2020 and ported to iOS the same year. The only powerboat sim that lets you bolt the cockpit to a hydraulic chair, then keep the same physics core in your pocket.

Stock without
the laptop.
A native iOS & iPadOS app for store and stock management.
Built-in barcode / QR scanning, on-the-floor stock counts,
workorder tracking, and a built-in timesheet that syncs both
ways into WooCommerce through our meldev-flx-custom
plugin.
We’ve been running open-weight language models on local hardware since they entered the public domain — long before “private LLM” was a marketing bullet. No cloud exfiltration. No per-token bills. Your data, your iron.
Llama, Mistral, Qwen, Gemma — quantised, served, and tuned to fit the GPU you already own. Air-gapped deployments included.
Maintenance manuals, ladder logic, your CAD library, your incident history. We curate the dataset, run the LoRA, ship the weights.
Vector stores hosted alongside your data. Document ingestion, chunking, citations — accountable answers with traceable sources.
A short brief is enough to start a conversation. We answer all messages within two business days, usually the same day.
