Lampe NG

Conception

L'idée de départ est de réutiliser une ampoule cassée pour en faire une lampe utilisant des LEDs. On peut trouver facilement des exemples d'ampoules de ce type dans le commerce !

J'ajoute des LEDs bleues à l'intérieur.

Je calcule les dimensions d'une structure géodésique en barreaux avec le site internet https://www.simplydifferently.org/Geodesic_Dome_Notes?page=3#2V/L2%20Icosahedron%20Dome

Pour le socle, je m'inspire de la montagne du destin (Mount Doom) décrite dans le roman le Seigneur des Anneaux de J. R. R. Tolkien (Sauron forge l'anneau unique dans les flammes de la montagne de feux, au Mordor ). Dans la trilogie cinématographique de Peter Jackson adaptée du Seigneur des Anneaux, le mont Ngauruhoe, un volcan de Nouvelle-Zélande, est choisi pour représenter la montagne du destin (https://fr.wikipedia.org/wiki/Mont_Destin).

J'utilise ce tutoriel pour créer le socle de la lampe : https://johnflower.org/tutorial/make-mountains-blender-heightmaps et je découpe cette simulation 3D en tranche comme j'ai déjà utilisé dans d'autres projet (par exemple T-REX Ball).

Et je modélise un nouveau culot en 3D pour assembler le tout !

Voici la simulation de l'assemblage sur Blender !

Intégration de la partie électronique dans le socle de la lampe !

Coller l'ampoule au nouveau culot en PLA !

Assembler le tout avec de la colle à bois, 5 vis M4 dans le culot, 8 vis et 8 écrous M4 pour le socle (méthode “Sandwich” en superposant les couches).

Hardware

S’équiper d'un circuit ESP8266 (https://fr.aliexpress.com/item/32779189539.html) et de quatre guirlandes LEDs (https://fr.aliexpress.com/item/32799804772.html)

Câbler les LEDs suivant ce schéma :

Programmation

Voici un tuto pour comprendre les grandes lignes de la programmation de l'ESP8266 : https://f-leb.developpez.com/tutoriels/arduino/esp8266/debuter/

Ce programme comporte plusieurs animations pilotables via le navigateur WEB. Connectez-vous au WIFI de la Lampe NG avec votre téléphone, avec votre tablette ou avec votre ordinateur :

Difficultés rencontrées

Malheuresement après avoir transporté plusieurs fois à vélo la Lampe NG durant l'épisode du Covid19, l'ampoule s'est décollée… Je l'ai recollée mais comme le nouveau cordon de colle dépassait de sa position initiale cela n'était plus esthetique. La partie haute de la Lampe NG est indémontable, j'ai donc du modéliser, imprimer et monter une bague haute supplémentaire en plusieurs parties pour la coller à travers les barreaux géodésiques.

Une nouvelle lampe est en préparation, inspirée des projets suivants :
- Lampe champignon par bumblebee
- Dôme géodésique fréquence 3 par bubuchelabuche
