Passionate about audiophile-grade audio engineering, I provide comprehensive electronic engineering services, from initial concept and system design through manufacturing, commissioning, troubleshooting and maintenance.

Electronic repair, troubleshooting, fault diagnosis and restoration

I provide professional troubleshooting and repair services for a wide range of analog, digital and power-electronic equipment. Each device is carefully inspected, measured and tested to identify defective components, intermittent faults, design weaknesses or age-related failures.

Design and development of analog and digital electronic systems, from prototypes to mass-produced products

Electronic schematic design and capture

Electronic measurements, simulations, test-bench development, functional testing, calibration, tuning, commissioning

Resolution of technical problems involving mathematics, geometry, physics, electricity, electronics and computing. Preparation of technical documentation in French or English.

Embedded firmware development in C for PIC microcontrollers, including real-time, multitasking and interrupt-driven applications

Integration of MOXA ans ESP32 platforms, ADCs, DACs, analog front ends, filters, touchscreens and communication interfaces such as I²C, SPI, UART, RS-232, RS-485, USB, TCP/IP and RFID.

Multilayer PCB layout, 3D board modelling and generation of complete manufacturing files

Including Gerber, BOM, placement, STEP, STL, SVG, DXF and PDF files. Technical review and optimisation of electronic schematics and PCB designs. Cost-effective PCB manufacturing and PCBA assembly based on customer-supplied Gerber, BOM and placement files.

PLC programming using WAGO controllers and CODESYS V3.5 for industrial automation and building automation systems

HMI programming and integration of industrial field interfaces.

Object-oriented Delphi 7 software development for Windows

Including data acquisition, equipment control, calculations, calibration, debugging, remote communication and advanced automation

Custom battery-pack design and assembly for multiple cell chemistries and configurations

Including BMS integration, high-power spot welding, cell balancing, storage charging and protective packaging



Bonjour! Guten Tag! I’m Joël Huser, a French-Swiss electronics specialist with 28 years of hands-on experience. Born in France and raised in Switzerland, I developed a passion for electronics at the age of 12, inspired by my father, an engineer.

After earning my Swiss Federal Diploma (CFC) in Electronics at Bobst in 2005 with the distinction of “Best Electronics Apprentice in the Canton”, I built extensive expertise in analog and digital circuit design, prototyping, troubleshooting, and industrial production. In 2016, I founded Joël Huser Électronique to provide professional electronic development and repair services.

My interests also cover high-fidelity audio engineering and the complete electrical-energy chain, including generation, transmission, distribution, consumption, and 50 Hz regulation.

From 2015 to 2023, I specialized in cathodic protection and corrosion control. As a Level 3 certified specialist, I designed, built, and maintained advanced protection systems and carried out corrosion assessments, feasibility studies, grounding concepts, and detailed technical documentation.

Fluent in French and English, I combine electronics, physics, chemistry, mathematics, energy, and technical computing to deliver reliable and innovative solutions.
