=== introduction ===
Pour une performance faisant appel à des chauffe-ballons sans thermostat et des pompes d'aquarium, j'ai conçu un boitier système permettant d'une part de mettre les personnes en sécurité (utilisation d'appareils électriques dans un environnement encombré par des aquariumset des ballons), d'autre part de commander par radio des relais permettant de maintenir les chauffe-ballons à température constante, les éteindre, les mettre en marche forcée.
