Ecran Led RGB : horloge météo

[Jeff]

Salut,

Tu aurais les fichiers pour l'impression 3D du boîtier stp ?

Tout est disponible sur le github : dossier "case" et j'ai même mis les sources autocad

[Jeff]

pas mal, je suis en train d'agrandir mon Nextion 3.5 en 5.0 avec sonde de T° et CO2

le lien insctructable est mort

Je t'avoue ne plus utiliser mon nextion depuis mon déménagement mais il me fait de l'œil, j'ai adoré ce projet et je lui cherche une nouvelle utilité

Cet écran 3D led est ce que je cherchais comme afficheur dans mon garage, sa prise en hauteur est déjà prévue dans la construction

[dokho]

J'adore fabriquer des projets DIY pour des besoins propre à moi et j'aime bien les partager, voici l'écran horloge /météo
Horloge_meteo_LED_RGB.jpg

Celui est fait à partir d'un ecran led rvb P4 de 256mm par 128 mm] de 64 pixels x 32 pixels.
Equipé d'un esp8266 et d'une alimentation 5V, 10A

J'ai imprimé 2 boitiers en 3D pour intégrer l'alim en 220v et l'esp8266
Boitier_3D_led_rvb.jpg

La librairie est https://github.com/2dom/PxMatrix

Je suis parti à l'origine de ce site
J'ai réalisé ce câblage sans le "E" en respectant les conseils de la librairie Px matrix. Je n'ai pas connecté D3.

On a le choix de la police, de la couleur, de toute son imagination.

Les infos sont issues :
D'une sonde de température de domoticz retravaillé par node red
L'heure, la date par node red
Les icônes météo sont récupérés via openweather sous node red.

Tout le dossier est ici :

Salut,

J'ai enfin branché mon écran, je commence à regarder le code et 1er truc sur lequel je bloque: les icones.

J'ai bien essayé de creer une icone toute simple en 15x15 sur gimp mais impossible de la convertir convenablement.
Comment as tu fait pour les tienne ?

Autre question, les icones météos ne respectent pas la couleur définie dans le code, une idée ?

[Jeff]

Tout d'abord mon écran fonctionne quotidiennement depuis plus d'un an et c'est sans doute un de mes meilleurs objets connectés avec le nextion. Parfois il y a des lignes qui scintillent comme des interférences mais ca part (sans doute des connections pas parfaite)
Je viens de me repencher dans le projet, le logiciel utilisé est "lcd image converter"
Après il faut fabriquer son image pixel par pixel et générer le code, regarde ce tuto dans le principe
https://www.youtube.com/watch?v=Q1iVtLQOZOI , il semble que c'est celui ci dont je me suis servi pour la partie lcd image converter.

[dokho]

Salut Jeff,

Ça me semble assez intéressant comme objet en effet, reste à savoir à quoi je vais l'employer (j'ai tellement d'idées en tête ).

J'étais tombé sur lcd image converter en effet, je suis en train de mettre à jour ma VM windows pour l'installer.

Une idée du pourquoi les icônes météo sont d'une seule couleur ? Est-ce aussi le cas chez toi ?


Merci

[Jeff]

Salut,
Tu peux choisir la couleur que tu veux, j'ai eu le problème, j'ai trouvé la solution mais je ne sais plus, il me semble que c'est une histoire des "bits", tu vas être obligé de faire des essais.
Met fond noir je crois et test des couleurs primaires...
En utilité, c'est un écran bien pratique pour heure, date, température...
Après ca peut-être petit message ou smiley pour offrir une petite pensée à la famille... tu peux gérer cela avec interface web dashboard avec nodered en jouant sur les topics comme mon code.

[dokho]

J'ai trouvé le pb: je m'étais trompé d'un pin dans le câblage.

[dokho]

J'avance doucement dans mon projet.

Il me reste:
- récupération de la consommation journalière (CounterToday) de mon P1 smart meter (teleinfo)
- couleur d'affichage différente en fonction des températures

[Jeff]

Content que tu y sois arrivé
Je ne pourrais plus m'en passer de cet écran, tellement pratique

J'ai quand même quelques galères
