Description The following are some highlights of the 2022-2023 season of EPFL Racing Team, where I was head of low-voltage electronics. Highlights Gallery

Description While I was at EPFL Racing Team, the driverless team mentionned that accurate ground speed estimation regardless of wheel slippage would be beneficial to their algorithms. Looking around at what was possible in this domain, I came across the possibility of harnessing the doppler effect with RADAR to estimate the speed of a vehicle with respect to ground. After discussing this with Prof. Skrivervik of the Microwaves and Antennas Group at EPFL, she proposed that I could focus my bachelor thesis on the design of the antenna array for such a system, as the full system was a bit too ambitious for a bachelor project. ...

Introduction The EPFLoop project was started as a participation in the SpaceX Hyperloop competition by EPFL students. After two participations in 2018 and 2019 and a year of hiatus, it was restarted as a research project in the EPFL DESL lab, as well as a startup. When I saw the announcement that the project was restarting, I expressed my desire to help in this endeavor in any capacity I could, and was subsequently hired for electronics development for the reduced scale testing project that has since beaten the world record for longest hyperloop test in 2024. ...

Introduction RRM2 is a fully analog 2 channel rotary DJ mixer. The project was started in 2020, and is still ongoing. Features Both channels can be passed through a phono preamp in case turntables are used, and a three band EQ can be applied to each channel independently before passing through the summing amplifier. Headphones can be used to preview the channels, and a master EQ can be used to control the overall sound before it is sent to the PA system. ...

Introduction During my first year at EPFL finding the time for personal projects proved impossible, so by the time I was done with my third semester I was itching for a new PCB to design. This came in the form of Project Moléson: a simple PCB full of individually adressable APA102 2mm wide RGB LEDs, that I built as a decorative necklace for a disguise I would wear at that year’s ski week-end party. ...

Introduction As my schoolmates and I were all thinking about what to do as an end of highschool project, myself and a good friend came up with the idea of building our own quadcopter flight controller, as we were both building our own racing drones from off-the-shelf parts. We therefore decided to start about six months earlier than the official start date and approval of the project, hoping that we could have it accepted. Either way it was going to be a fun endeavor, so we set out to learn everything there was to learn about quadcopters and the way they were built. ...

Introduction The aim of this project was to build on what I learned during the RetroWatch project, and create a new watch around the SSD1306 OLED display that would allow for more complex features and the challenge of making all the components fit on a PCB the size of the display, while still using the PCB as the main structure for attaching the wristband. Description The design is based on the ATSAMD21 ARM Cortex M0 microcontroller, and features a STMicroelectronics Magnetometer for compass functionnality, and a LiPo management IC for SOC estimation and charge control. Making all the components fit was a great learning experience. ...

Introduction The aim of the project was to make a fun use of these vintage bubble LED displays I came across while first exploring electronic protoyping websites. Since I grew up in Switzerland the choice of making a watch came naturally. I set out to design a first version that used an ATMega328 as this was the microcontroller I was most familiar with due to its use in the Arduino Uno. ...

Intro The goal for this project was to customize my siser’s shoes with LED strips. Although they were eventually never really used, this mostly gave me an excuse to design my first (actually working) PCB. Sidenote Here is a picture of my first actual PCB design. Clearly defining the ground pours with a width of zero thinking it would not matter was a mistake. Design The design idea was quite simple : essentially make my own tiny Arduino board. Since only minimal IO was needed, I decided to use the ATTiny85. With some breakout boards for the SOIC package of the ATTiny designed and ordered, prototyping was done on an Arduino Uno, then replacing it with a DIP package of the ATTiny directly on the breadboard ...
