Marc et Jean-Yves ont réaliser des modélisations de phares :
Le four, le Stiff, le Créach, la Jument et Kermorvan sont réalisés.
Ces modélisations 3D doivent clignoter selon leur signature lumineuse,
par ex le Four possède 5 éclats toutes les 15s.

Ainsi, conformément à notre devise, CONCEVOIR – MODÉLISER – FABRIQUER
voici les différentes étapes de ce projet en images :

Test du montage sur breadboard : alimentation 3V led + résistance 10Ω, 2 résistances 100 kΩ et 10 kΩ pour le pont diviseur.
Utilisation de la bibliothèque tinysnore pour n’activer la consommation que lors des flashs lumineux

Recherche des valeurs de ponts diviseurs avec les valeurs de résistance disponibles

Réception des circuits imprimés fabriqués

Montage des composants soudés, la pile est au verso et restera accessible sous le phare

Cette année 2020 s’achève, en espérant que son lot de contraintes, de confinements et autres complications disparaissent avec elle.

Place aux vœux : en premier de la santé pour tous, puis de la créativité et de la curiosité pour une année riche en découverte.

Enfin pour notre association, j’espère que l’on pourra se rassembler afin de partager nos projets et notre vision du futur de l’association lors d’une assemblée générale mais surtout d’un moment convivial.

Et pour terminer, 2021 sera peut-être l’année de naissance d’un lieu fédérateur de partage, de création et de fabrication. Une fabrique de territoire qui aurait toute sa place en pays d’Iroise, et qui rassemblerait tous ceux qui désirent comprendre, apprendre et entreprendre.
