The physical layer: high-voltage systems, embedded boards, power electronics.
Engineering write-ups of physical builds, documented with the same rigor as the software portfolio — schematics, measurements, and honest failure notes. The first build logs are in preparation now.
Grid frequency under load — a real droop model
Three phases at 50 Hz. Drag the load and the frequency droops exactly as a synchronous grid does; drag the inertia and watch how fast it moves. This is the physics the hardware on this site exists to serve.
L1 · L2 · L3 — 230 V phase voltages · Δf = −f·0.04·ΔP · |df/dt| ≤ f·ΔP/2H
Three tracks of physical engineering
Each track publishes complete builds — from first schematic to measured result. No renders passed off as photographs, no specs without instruments behind them.
High-voltage systems
Traction power, substation hardware, protection and measurement chains — the energy layer, up close, from the engineer who digitises it for German rail.
First build log in preparationEmbedded control boards
Deterministic controllers, RTOS firmware, signal integrity, and hardware-in-the-loop test rigs that prove the timing before anything touches a real plant.
First build log in preparationPower electronics
Inverters, converters, and the switching hardware that connects renewables to real grids — measured, thermally characterised, documented.
First build log in preparationHow every build gets published
The same discipline that governs the software portfolio governs the bench: nothing is claimed that an instrument did not show.
Design & simulate
Schematics and models first. Every build log opens with the design intent and the simulation that justified it.
Build & measure
Real hardware, real instruments. Scope captures, thermal readings and load tests are the evidence — published as recorded.
Publish with receipts
What worked, what failed, and why. Failure notes stay in the record: they are what make the successes credible.
The software side is already live
The software & AI portfolio
Capability register, work registry, physics-informed learning and agentic middleware — in four languages.
