Il faut bien nourrir le chat pendant les vacances, puisque nous ne pouvons pas toujours l’emmener avec nous.<\/p>\n

On trouve toute sorte de montage sur internet, du broyeur de croquettes jusqu’au montage de \u00ab\u00a0Doc\u00a0\u00bb dans \u00ab\u00a0retour vers le futur\u00a0\u00bb !<\/p>\n

J’ai commenc\u00e9 par faire un premier prototype, mais j’ai \u00e9t\u00e9 confront\u00e9 \u00e0 un probl\u00e8me de taille, puisque la machine peut se bloquer, si une croquette se coince \ud83d\ude41<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

Je suis donc revenu \u00e0 un syst\u00e8me comparable aux distributeurs de corne flakes, ou plus g\u00e9n\u00e9ralement de dry food. Pour faire simple, une roue avec des ailettes dans un tube, sous un entonoire, sous un grand tube.<\/p>\n

La difficult\u00e9 a \u00e9t\u00e9 de trouver un \u00e9quivalent \u00e0 cette roue \u00e0 ailettes, strat\u00e9gique au montage. Finalement, j’ai pens\u00e9 utiliser ca :\u00a0\"wp-1466453449644.jpg\"<\/a>\u00a0un goupillon pour nettoyer les bouteilles.<\/p>\n

 <\/p>\n

J’ai juste coup\u00e9 aux bonnes dimensions, et utilis\u00e9 un bout de domino \u00e9lectrique pour caler en translation, et solidariser avec le moteur.<\/p>\n

 <\/p>\n

Ensuite, j’ai fix\u00e9 une petite plateforme en bois pour poser le moteur, et ajouter quelques bouts de PVC et construit un support en bois :<\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

 <\/p>\n

Au final, cela ressemble \u00e0 ceci :<\/p>\n

Maintenant, je m’attaque \u00e0 la programmation.<\/p>\n

Je vais utiliser un AT-MEGA 328p (arduino UNO from scratch), un ESP8266, et quelques autres composants …<\/p>\n

 <\/p>\n

Apres une dizaine de jours d’utilisation, ce montage remplie sa fonction \u00e0 merveille. Une dose est bien distribu\u00e9e toutes les 12h environ. Plus exactement, toutes les 12h05 : il faudra am\u00e9liorer la partie programmation horaire.<\/p>\n

Le niveau de croquettes \u00e9volue selon les pr\u00e9visions, assez r\u00e9guli\u00e8rement, m\u00eame si le capteur n’a une pr\u00e9cision qu’en centim\u00e8tre.\u00a0\"PetFeeder_2-week\"<\/a><\/p>\n

C’est aussi quelque chose \u00e0 am\u00e9liorer pour la prochaine version… si possible, approcher une pr\u00e9cision de quelques millim\u00e8tres.<\/p>\n

 <\/p>\n

Et puisqu’il est toujours pr\u00e9f\u00e9rable de v\u00e9rifier qu’un bricolage fonctionne convenablement, voici le preuve en image (cam\u00e9ra IP en mode infra-rouge, donc en noir et blanc<\/em>)\"607228_2016-06-26-22_52_21.jpg.jpg\"<\/a><\/p>\n

La chat a tr\u00e8s vite rep\u00e9r\u00e9 le bruit de ce dr\u00f4le d’engin, et se pr\u00e9cipite dessus.
\nJe peux l’affirmer gr\u00e2ce \u00e0 une autre webcam, qui couvre son panier dans le garage, pr\u00e8s de la chati\u00e8re.<\/p>\n
