KiCad Plugin DevelopmentCode - 27-02-2023

KiCad is a powerful open-source electronics design automation tool. Plugins can improve its functionality and streamline the design process. This article focuses on two plugins I developed to enhance KiCad: Auto Silkscreen Placer, which automatically moves silkscreen part designators to readable locations, and Pinout Generator, which exports component pinouts to various formats, including C/C++ code, CSV, and FPGA constraints files.

Electromagnetic interference mappingCode - 22-04-2019

Accurate mapping of near-field electromagnetic parasitic emissions is crucial for designing, debugging, and pre-compliance testing of electronic devices. However, traditional EM scan methods are often expensive and lack the required level of detail and speed. This article describes two innovative methods for creating fast and affordable high-resolution 2D maps of RF EMI for printed circuit boards (PCBs) and other electronic devices.

AI astronomy pictures processingCode - 08-03-2019

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.

AI-powered digital signal processingCode - 10-02-2019

Machine learning is fantastic to apply complex mathematical operations without being specifically programmed like in conventional algorithms. In this article, I share two artificial neural networks experiments related to digital signal processing (DSP): discrete Fourier transforms and signal corruption recovery.

Interact PHP - comment systemCode - 17-08-2018

Interact is a simple PHP open-source comment system that can be added to any website in minutes to improve interactivity and user's involvement. Client-side, it is very lightweight (<6 KB CSS and JS combined) and intuitive (no logins, no cookies, etc.). Server-side, it is very easy to setup, manage and even customize to fit your needs.

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

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

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.

ElectroDB - Android appCode - 14-10-2017

ElectroDB is a powerful, offline Android app I created for electronics enthusiasts like me. With its 12000+ (and growing) components database, you will find all the information you need to complete your electronic projects in less time. In this article, I showcase my app, and go into more technical details on the inner working.
