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 conceptualization, design and capture on Kicad or Altium, simulations on LTSpice.

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

Resolution of technical problems involving mathematics, geometry, computing, physics including electricity, electronics, computer science, etc. Preparation of technical documentation in French or English.

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

Integration of MOXA ans ESP32 platforms, ADCs, DACs, analog front ends, filters, touchscreens, electromechanical parts 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

PCB design review and optimisation. Cost-effective PCB fabrication and assembly from the customer's files. Deliverables including Gerber, BOM, placement, STEP/STL and PDF files, etc. Kicad and Altium.

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

HMI programming such as touchsreen, integration of industrial analog and digital 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

Working with a high-power 12kW capacitor spot welder, I create battery packs, protected and managed by a Daly bluetooth with an OLED screen BMS, charged by ISTD Q8 Max 1000W up to 8S charger(s), providing cells-balancing full or storage charging. Protective packaging



Bonjour! Guten Tag! I’m Joël Huser, a French-Swiss electronics specialist with 28 years of hands-on experience. Born in 1983 in France and raised since 1988 in Switzerland, I developed a passion for electronics at the age of 12, inspired by my father, an engineer in the field.

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 (metals protection against corrosion) in a small company. As a level 3 swiss certified specialist, I design, build, and maintain advanced protection systems. I conduct corrosion assessments, stray current measurements, feasibility studies, grounding system designs, technical drawings, and various other studies – particularly within the environmental, railway, energy and civil engineering sectors – as well as preparing authorization applications, all supported by detailed technical documentation.

Fluent in French, English and German, I combine electronics, electrics, energy, physics, chemistry, mathematics and computer science to deliver reliable and innovative solutions.
