====== Lampe NG ====== {{{project picture:{{:projets:lampeng:lampeng.jpg?300|}} machines: Trotec400 Ultimaker materiaux: CP PLA logiciels: Blender inkscape ArduinoIDE fichiers:{{:projets:lampeng:go2.svg|}} {{:projets:lampeng:socle.svg|}} {{:projets:lampeng:culot.stl|}} {{:projets:lampeng:bague-culot.stl|}} liens:https://www.simplydifferently.org/Geodesic_Dome_Notes?page=3#2V/L2%20Icosahedron%20Dome tags: usager:Go2 licence:cc-by-sa }}} Lampe géodésique pilotable avec le WIFI de votre mobile ! ;-) ===== 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 ! {{ :projets:lampeng:ampouleled.jpg?300 |}} J'ajoute des LEDs bleues à l'intérieur. {{ :projets:lampeng:fairyleds.jpg?300 |}} 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 {{:projets:lampeng:2vl2.map.jpg?500 |}} {{:projets:lampeng:2vl2.calcul.jpg?500|}} 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). {{:projets:lampeng:lotr-mount_doom.jpg?300 |}} {{:projets:lampeng:le_ngauruhoe_et_le_ruapehu_vus_du_sommet_du_tongariro.jpg?600|}} {{:projets:lampeng:montngauruhoe.jpg?1000|}} 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 [[projets:t-rex_ball|]]). Et je modélise un nouveau culot en 3D pour assembler le tout ! {{:projets:lampeng:culot.jpg?500|}} Voici la simulation de l'assemblage sur Blender ! {{:projets:lampeng:01.png?1000|}} Intégration de la partie électronique dans le socle de la lampe ! {{:projets:lampeng:02.png?1000|}} ===== Réalisation ===== Récupération d'une ampoule cassée et découpage du culot [[https://www.youtube.com/watch?v=KHANh7x2XtM]]. Découpe à la découpeuse laser du socle {{:projets:lampeng:socle.svg|}}. Découpe à la découpeuse laser des barres géodésiques {{:projets:lampeng:go2.svg|}}. Impression 3D du culot {{:projets:lampeng:culot.stl|}} 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 : {{:projets:lampeng:schemaelectronique.png?500|}} Connecter le circuit ESP8266 suivant ce schéma : {{:projets:lampeng:circuitselectronique.png?500|}} ===== 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.

Je l'ai recollée mais comme le nouveau cordon de colle dépassait de sa position initiale cela n'était plus esthétique. 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. {{:projets:lampeng:bague-culot.stl|}} ===== Rendu Blender Hotel ===== {{:projets:lampeng:lampeng-hotel_.jpg?1200|}} Inspiration : [[https://blendswap.com/blend/6355]] ===== Rendu Blender Chambre ===== {{:projets:lampeng:lampeng-perso_.jpg?1200|}} Inspiration : [[https://dimensiva.com/3dmodels/armchair-daw-by-vitra-eames/]] & [[https://www.designconnected.com/fr/category/Tables/E-Volved-table_p3882]] ===== GIF ===== {{:projets:lampeng:anim.gif}} ===== Photos ===== {{gallery>:projets:lampeng:photos}} ===== Suites du projet ===== Une nouvelle lampe est en préparation, inspirée des projets suivants : \\ - [[projets:lampe_champignon|]] par bumblebee \\ - [[projets:dome_geodesique_frequence_3|]] par bubuchelabuche \\ Retrouvez cette nouvelle version sur internet avec le QRcode ci-dessous 8-) \\ {{:projets:lampeng:gif500.gif}} **Made by Go2**
