4WD robot
I found a cheap 4 wheel drive chassis on eBay and decided to make a remote controlled robot out of it. Thus, I made a simple board with two H-bridge modules, an NRF24L01 wireless module and Arduino pro mini.
Distributing a Helm chart on Artifact Hub
Building applications in a microservice architecture has become more and more popular recently. With this design pattern, an application is composed of multiple services that run independently and generally share data across network protocols.
Energy transformation demonstration
Earlier this year, a friend of mine was organizing an event to promote eco-friendly behaviors. She wanted someone to talk about our relationship with energy and asked me to give a presentation on the topic, which I agreed to. I wanted the presentation to be entertaining so I designed a set of hardware demonstrations aimed at explaining physical concepts related to energy.
Food manager
The other day, I found myself putting on some weight. This rather surprised me as I thought I was having a healthy diet and exercised almost daily. To identify the root of the problem, I decided to start measuring my calorie intake as well as the macronutrients that constitute said intake.
Group and User Pickers
With the user management and group management microservices, users and their groups can be easily queried through HTTP requests. However, the GUI that the user interacts with must also be properly designed so as to provide an optimal UX. To facilitate the query of users via the GUI, I designed a group and user picker component for Vue.js that can be easily installed using NPM.
Group management microservice
As a graph database Neo4J is a great choice to manage highly relational data. On the other side, a great number of applications feature at least some form of user management system. With Neo4J, those users can be store as nodes and connected to other items via relationships. A typical example would be a blog, where both articles and users are individual nodes while authorships are represented by a relationship.
Home automation
Few would argue that having lights turned on in a room without occupant is a waste of electricity. Ideally, lights and other appliances like air conditioners would only be turned on when someone is around. This project is a NodeJS application that gathers data about the occupancy of an apartment and manages appliances accordingly.
Image upload microservice
An image is worth a thousand words and probably even more if comparing their size in bytes. When designing my CMS, I originally intended to store images directly in the article, encoded in Base64. However, this would considerably increase the size of each article, making the whole CMS slow.
IoT Kernel
Over the years, I have written firmwares for various IoT devices such as lights, locks or heaters. Those firmwares would generally handle a common set of basic functions like managing wifi connection, serving a configuration web interface over HTTP or exchange MQTT messages. However, having to implement and maintain those functions for each individual firmware quickly became tedious work. Consequently, I decided to write a library to handle all those basic functions. This library is used as a base for IoT device firmwares, on top of which device-specific logic can easily be added.
IoT LED controller
Smart lights are usually some of the first appliances to be added to a smart home. Although those can nowadays be purchased easily from various brands, I wanted to have my own hardware so as to integrate it better with other devices and software. Thus, I decided to an IoT LED controller that I can use in various projects where lighting has to be controlled via network protocols.
