Geofrey Marcel

Mechanical and composite materials engineer by training, my professional projects have led me to train in electronic design and programming for embedded systems. I now have over 4 years of experience in these fields.

I started my professional career by launching Trilys, with the aim of designing, manufacturing, and marketing electric karts. This experience was an opportunity to develop my first systems: lithium batteries, BMS, power distribution and data logging boards, as well as carbon and fiberglass parts.

Today, Pierre, my partner, and I can offer you design, manufacturing, and programming services for electronic boards in the fields of robotics, the Internet of Things, and leisure vehicles. We can supply you with lithium batteries, chargers, and other accessories and help you optimize their use. Finally, we design your mechanisms in 3D CAD and can 3D print them in-house.

Regarding mechanical design, we offer you the right manufacturing method for your parts and design accordingly, whether it's 3D printing, laser cutting, composite molding, injection, welded assembly, machining, casting... We have a full Solid Edge ST10 license that also allows us to perform reverse engineering, mechanical strength calculations, and thermal calculations.

As for electronics, we mainly work with the STM32 microcontroller range and prefer to use CAN networks to ensure reliable communication between systems. We also work on Arduino for prototyping. We code in C under TrueStudio for more efficient development and debugging.

We have the interface to program SEVCON Gen 4 and 5 controllers.
