Recently I got a 3D printer and I have been experimenting with it. After a few prints for “very important things”, like a drill guide, a wine bottle holder or a Lego Extension Card for my Framework laptop, I thought that it was time to design something myself.

Dev Container is an open specification to build and use an OCI container as development environment. It is something I already used in my Chip 8 emulator for having a development environment that can be reused across platforms.

During the last months I’ve been developing a CHIP-8 emulator in Python. My main goal was to learn how an emulator works and how to program one. That’s why I tried to write as good and comprehensive code as possible.

A beautiful and decorative pot with flowers created with my children. My contribution was some soldering and electronics for powering RGB LEDs that cycle across colors. The components used are a couple of RGB LEDs with their corresponding resistors and a Raspberry Pi Pico (my favorite microcontroller).

This is a little project for our greenhouse. Even if we do not really need it (and I still need to make sure that the battery will be safe), this circuit uses a Raspberry Pi Pico for monitoring temperature, humidity, gas and and atmospheric pressure.

Using an ESP32, a potentiometer, a temperature and humidity sensor, and a sleek 7-segment display, I crafted a functional and stylish addition to any workspace. Nestled discreetly within the IKEA frame, this clock is not just about telling time.

What to do after creating a Space Invaders game for an RGB LED Matrix? Obviously, build a cabinet for RGB games. Using an online service called Boxes.py’s Console2 for designing the cabinet and the PiTop-4 to run the software, I iterated over the previous code and adapted it to the actuators provided by the PiTop: a potentiometer and a button.

Embarking on the journey to build a video game from the ground up has always been one of my ambitions. Understanding the inner workings of a video game and implementing classics have been on my to-do list since my university days.

In the late ’90s, I purchased a Genius DB15 Wheel controller for playing driving video games. Regrettably, it turned out to be a poor choice as the potentiometers used in constructing the wheel and gear produced significant noise.
