Services

End-to-end engineering support, in one place.

// Core specialties

Electronic schematic — power control and boost converter circuit
PCB layout in EDA software — multi-layer routing view3D render of a populated PCB with SMT components

Electronics design

We help take a product from concept to working prototype and into low-volume production:

  • schematics and PCB layout (single- and multi-layer)
  • component selection, BOM, EOL/risk analysis
  • prototyping, THT/SMT assembly, functional tests
  • diagnostics with oscilloscope, logic analyzer, LCR meter
  • CE / EMC certification support

We work with PCB manufacturers in Poland and Asia — picking the vendor based on lead time and IPC class.

Software

We build the full vertical stack — from the MCU to the user interface:

  • embedded firmware in C (STM32, ESP32, AVR, PIC)
  • desktop apps in C# (.NET, WinForms / WPF) and Python (Qt, automation tooling)
  • Android apps (Java, Kotlin)
  • communication protocols (UART, SPI, I²C, CAN, Modbus, BLE)
  • cloud integrations and local interfaces (REST, MQTT)

3D Printing — FDM and SLA

We print in engineering and specialty materials:

  • flame retardancy UL94-V0
  • high-temperature resistance
  • elastomers (TPU, TPE) at various Shore hardness
  • biocompatibility (ISO 10993)
  • transparent, ESD-safe, glass-fiber filled nylons

From single prototypes to small batches. We help you pick a material against a specific standard.

Technical documentation flow: requirements, drawings, validation, certification

Technical documentation

Complete documentation alongside the product:

  • ISO-compliant technical documentation
  • user and service manuals
  • datasheets, drawings, schematics
  • functional and environmental test reports

Complementary services

CAD design

We model parts from scratch or improve existing client files:

  • modelling for 3D printing (FDM, SLA) and CNC machining
  • DFM analysis — design tuned for the chosen process
  • technical drawings and production documentation
  • STEP / IGES files, machine-specific export

We work in Fusion 360, SolidWorks and FreeCAD.

Laser & CNC

  • 10 W laser marking and engraving on stainless steel and titanium
  • CNC engraving in metal, plastics and wood
  • satin finishing of metal components
  • mechanical prototyping (turning, milling, 3D printing)

Ideal for nameplates, serial numbers, tooling and decorative parts.
