TransmutationsDeBase : Différence entre versions

introduction

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