Ars Magna Lab
Machines to think, play and help
A YouTube channel by Edu Herraiz about the projects he builds in Mallorca: home automation, apps and games, AI and science communication. Each video shows how it's made, from the idea to the result. The videos are in Spanish.
The name comes from Ramon Llull's Ars Magna, the reasoning machine he conceived on Puig de Randa.

Home Assistant foosball table
An old, restored Córdoba foosball table that keeps score by itself. Infrared beams in the ball return lanes tell an ESP32 that runs the match, and Home Assistant turns it into a stadium scoreboard on a tablet, with a commentator, music and voice control. LED strips celebrate every goal. It all runs on batteries, hidden inside the cabinet, without touching the goals.

Ars Domus
Your house in 3D from a floor plan, some photos and public land data, to walk around in the browser. It keeps the current house and a renovation proposal, and you switch between them without moving the camera. Nothing is modelled by hand: Claude Code turns the sources into data and three.js draws them.

Ball Radar
A GPS treasure hunt to play outdoors. Someone hides the 7 balls by walking around a park or the neighbourhood, and the others have to find them guided by the radar. Built with Flutter for Android.
