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.

Electromagnetic interference mappingCode - 22-04-2019

Electromagnetic interference mapping

Mapping near-field electromagnetic parasitic emissions is useful for the design, debug and pre-compliance testing of electronic devices. Unfortunately, there is no simple way to make EM scans with sufficient level of details/accuracy, speed and reasonable cost. Hence, I developed this solution to make high-resolution and fast 2D maps of RF EMI for PCBs and more.

AI astronomy pictures processingCode - 08-03-2019

AI astronomy pictures processing

Digital image processing can be used to remove noise and signal distortion from pictures. It is particularly useful for astronomy, as the details are faint and often blurry. The objective of this project is to define an artificial neural network (ANN) and train it with machine learning to take several noisy, convoluted astronomy pictures and output a single processed photograph.

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.

Getting started with RTL-SDRCode - 24-07-2018

Getting started with RTL-SDR

Software Defined Radio (SDR) is a radio communication system where components that have been traditionally implemented in hardware are instead implemented by means of software. RTL-SDR is an extremely inexpensive way to start exploring, demodulating, decoding... about anything you could thing of in the VHF and UFH radio range. This article is a quick start guide with RTL-SDR to begin capturing and decoding signal on GNU/Linux, and two simple example projects.

Gimbaled Model Rocket SimulatorCode - 08-05-2018

Gimbaled Model Rocket Simulator

Thrust vectoring is the ability of an aircraft, rocket, or other vehicle to manipulate the direction of the thrust from its motor in order to control the attitude of the vehicle. I started designing and building a model rocket with a gimbaled thrust system. Impulse is my open-source and cross-platform simulator for gimbaled thrust rockets that accurately simulates the rocket's physics.
