With up to 8 channels, high-performance analog interfaces, and multiple data output options including USB, Bluetooth, and microSD, BioSignals is a versatile and low-cost solution suitable for a wide range of research applications. This article provides an overview of the system's features, design, and potential use cases.

RF Passive Differential ProbeElectronics - 10-03-2023

RF Passive Differential Probe

This passive RF differential probe is intended for the measurements of RF circuits within the frequency range of 500 MHz to 6 GHz. It is ideal for in-circuit measurements where no test port is available and has minimum effect on the DUT while being inexpensive to produce. This article goes over the design, performance, simulation and measurements of the device.

Microfluidics Electrowetting platformElectronics - 20-01-2021

Microfluidics Electrowetting platform

Microfluidics is an area of research based on the manipulation of small fluid volumes on the order of microliters or nanoliters. I designed µDropplet, an inexpensive plateform with an 8×8 array of electrodes driven by a high voltage to experiment with various microfluidics techniques and materials. This article describes the design, usage and some tests results obtained with this system.

3D Lidar Scanner MK2Electronics - 14-10-2020

3D Lidar Scanner MK2

This 3D Lidar utilizes an innovative mechanical scanning system to achieve high-resolution scans at an exceptional scanning rate. The Lidar employs a mirror to scan the beam throughout the room, without the need for any moving electronic parts. What's more, it can be fully 3D-printed. This article offers detailed insights into the design, construction, and usage of this device.

Radio Astronomy BasicsElectronics - 07-09-2020

Radio Astronomy Basics

Radio astronomy is the study of celestial objects at radio frequencies. An amateur astronomer with a very simple and inexpensive setup can perform some interesting measurements. This article describes my Ku band setup and some experiments we can do with it.

Hairpin filter designElectronics - 05-07-2020

Hairpin filter design

Electronic filters are circuits which remove unwanted frequency components from the signal to enhance wanted ones. The hairpin topology is a microstrip band-pass filter for the gigahertz band (UHF). They can be very useful with SDR to improve the reception. This article features a Javascript generator for these. It also shows their design and my results.

Acoustic beamsteering with a speaker arrayElectronics - 14-03-2020

Acoustic beamsteering with a speaker array

Beamforming is a signal processing technique to get a directionnal signal transmission from an array of emitters. By controlling the relative phase and amplitude difference between the elements, we can shape the emission/reception pattern according to our needs. For this project, I designed, built and measured a phased linear array of speakers.

Reaction Wheel Attitude ControlElectronics - 28-11-2019

Reaction Wheel Attitude Control

Reaction wheels are a way for spacecrafts such as the Hubble Space Telescope to achieve 3-axes attitude detumbling and control. It uses the conservation of angular momentum. For this project, I made a model of a satellite with a reaction wheel to demo the effect and play with the parameters/control algorithm.

Shablocks - Electronic modular labElectronics - 22-09-2019

Shablocks - Electronic modular lab

Shablocks is a modular and compact electronic lab system. It is made of open-hardware blocks: variable power supply, oscilloscope, component tester, etc. Everything can be assembled on the go to fit your needs.

OpenEMG Arduino SensorElectronics - 18-06-2019

OpenEMG Arduino Sensor

Electromyography (EMG) is a commonly used electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. OpenEMG is a project that aims to create an open-source, easy-to-make EMG module that can capture muscle information from Arduino or any other micro-controller. With this module, users can measure muscle activity and use the data to explore various applications such as robotics and prosthetics.

3D-printed prosthetic handElectronics - 06-04-2019

3D-printed prosthetic hand

The human hand is made up of a total of 27 individual bones connected by joints and ligaments, and operated by muscles situated in the hand and wrist. This project's objective is to mimic it and build an open-harware fully 3D-printed prosthetic hand.

EDF motor designElectronics - 19-02-2019

EDF motor design

Electric ducted fans (EDF) are an efficient way of producing thrust for an aircraft. However, there are a lot of variables that can be fine tuned to optimize their performance: body curves, fan blade pitch, duct length, number of fan blades, etc. Using both simulation and experimental results, the objective of this small project is to enhance the thrust per input Watt of my design.

Homemade PCB manufacturingElectronics - 21-10-2018

Homemade PCB manufacturing

Homemade PCB manufacturing is a great way to get inexpensive board prototypes with no delay. In this article, I show the method I came up with to get reliable, fast and precise PCBs with no headaches using a 3D printer, a permanent marker and any etchant.

S3D Evolved - compact 3D printerElectronics - 20-07-2018

S3D Evolved - compact 3D printer

S3D Evolved is an open source 3D printer that is reliable, compact and inexpensive to build. Its 100x100x100 mm build volume and robust frame means that it can be transported easily, while being sufficient for most of your prints.

ECE3SAT - Helmholtz CoilsElectronics - 11-02-2018

ECE3SAT - Helmholtz Coils

Helmholtz coils are a pair of facing coils that generate an almost uniform magnetic field along one axis. In my end-of-study project at ECE Paris, we designed, built, and qualified a full 3D Helmoltz coil magnetic simulation environment for CubeSats. This environment enables the testing and verification of magnetometers and magnetorquers for the ADCS subsystem.

Micro Laser MachineElectronics - 10-02-2018

Micro Laser Machine

This compact laser engraving CNC machine can burn on wood and most materials. It is upcycled with CD/DVD drives from old computers. It is a fairly easy machine to build and use, thanks to the open-source control software LaserGRBL.

3D Lidar Scanner

As a 3-day project, I created this 360° lidar scanner using a Garmin™ LIDAR-Lite v3. With its data acquisition and visualisation code, this turret can generate a fairly accurate 3D point cloud that we can import in CAD software. The source-code and some design details are available in the article.
