Hardware prototyping
From concept sketch to functional PCB. We design schematics, lay out boards, write firmware, and bring up the first ten units in our in-house lab — including EMC pre-compliance and thermal profiling.

Nadchodzi4 · Studio & Lab
Hardware, software, and molecular research — built in one workshop.
We design POS terminals, prototype connected devices, and run peptide stability studies under one roof. Three disciplines, one team that ships working artifacts instead of slide decks.

What we do
Three practices that reinforce each other
A small team of electrical engineers, firmware developers, and biochemists working in the same space. We pick up a multimeter, a soldering iron, and a pipette in the same afternoon — and that cross-pollination shows in the final artifact.
POS systems & terminals
Custom point-of-sale hardware, payment peripherals, and the embedded software that ties them together. PCI-aware firmware, offline-tolerant checkout flows, and field-repairable enclosures.
See POS capabilitiesPeptide stability studies
Controlled accelerated-aging and real-time shelf-life assays for peptide-based formulations. HPLC, mass-spec, and bioassay readouts — with raw chromatograms delivered alongside the report.
View research methodsEmbedded software
RTOS and bare-metal firmware for Cortex-M, ESP32, and RISC-V parts. Secure boot, OTA update infrastructure, and deterministic real-time scheduling — written by people who also read the datasheet.
Firmware stack detailsMechanical & enclosure
Sheet-metal, CNC-milled, and injection-molded enclosures. Drop-test fixtures on site. We sweat the stack-up, the connector cutouts, and the serviceability hatch before the first prototype is cut.
See enclosuresCompliance & certification
CE, FCC, and RoHS paperwork, plus the technical files auditors actually want to see. We also prepare stability study dossiers formatted to ICH Q1A(R2) for clients submitting to notified bodies.
Compliance workflow
Why teams hire us
A studio that closes the loop between design, build, and measurement
Most vendors hand you a deliverable and disappear. We keep a continuity of context from the first sketch to the long-tail data — the same engineers who drew the schematic run the bench test and review the field data six months later.
One team, three disciplines
Hardware, retail software, and biochemistry under one roof. Decisions made by the people who will build, test, and ship — not handed off to a committee.
Artifacts, not slide decks
We deliver working PCBs, installed terminals, and signed stability reports. Every proposal includes a physical or analytical sample you can hold and test.
Honest about what fails
We publish our negative results and bench-test failures in the journal. If a design won't pass EMC, you'll hear about it on day three, not after the tooling is cut.
Built for the field
Enclosures are designed to be opened with a single Torx driver, firmware supports rollback, and stability protocols use real shipping profiles — not just 25 °C shelves.
How a project runs
A predictable five-step arc, with hard checkpoints
Every engagement — whether a single POS terminal or a 12-month peptide program — runs through the same five milestones. You always know what's next, what's shipped, and what's blocking.
Scoping
One-week discovery. We define acceptance criteria, write a one-page brief, and quote a fixed-price phase one.
Prototype
Schematic, board bring-up, and a functional firmware build. For research, the method validation and first chromatograms.
Iterate
Two weekly cycles of bench testing, design review, and revision. You see the rev-A board, then rev-B, then rev-C.
Qualify
EMC pre-scan, drop tests, accelerated-aging runs, ICH-aligned protocols. We sign the report jointly with you.
Ship & support
Production hand-off, field telemetry, and a 24-month support window with named engineers on the ticket.
Field notes
What clients say after the first shipment
Three recent engagements — a payment terminal rollout, a connected sensor, and a stability program for a peptide active. Names abbreviated on request.
“They shipped a working PIN-pad in eleven weeks from kickoff. We expected twelve months. The firmware has been in the field for two years with a 0.3 % RMA rate — the best in our line-up.”
“Their stability report was the only one our notified body accepted without a single follow-up question. The raw HPLC data was right there, properly indexed, with the integrator settings we asked for.”
“We came in with a vague 'make a rugged handheld'. We left with a CE-marked unit, a refillable battery pack, and a service manual our field techs actually use. Worth every euro.”
Working with us
Bring us the thing that won't quite work yet.
A terminal that drops off the network. A peptide that loses potency at room temperature. A sensor that's never going to ship in its current enclosure. We're at our best on the problems other teams have parked.
