Pour ceux d'entre nous qui vivent dans l'h\u00e9misph\u00e8re nord, les jours raccourcissent et il est de plus en plus difficile de sortir du lit. Dans cet \u00e9pisode de notre s\u00e9rie Paragon Projects, nous examinons un projet qui sera d'autant plus utile que les jours raccourcissent : le piratage d'une machine \u00e0 caf\u00e9.<\/p>\n\n\n\n<p>Ce projet date en fait de deux ans, mais je dirais qu'il est tout aussi pertinent aujourd'hui qu'il l'\u00e9tait en novembre 2021.<\/p>\n\n\n\n<p>Ce document a \u00e9t\u00e9 \u00e9labor\u00e9 et partag\u00e9 par <a href=\"https:\/\/andybradford.dev\/2021\/11\/23\/hacking-some-smarts-into-a-basic-coffee-machine\/\">Andy Bradford<\/a>. Andy a expliqu\u00e9 que le probl\u00e8me \u00e9tait que la machine \u00e0 caf\u00e9 pr\u00e9parait une tasse de caf\u00e9, mais que parfois \"je la faisais infuser et j'oubliais de retourner chercher la boisson, la laissant se p\u00e9rimer sur la plaque chauffante, alors j'ai d\u00e9cid\u00e9 de voir si je pouvais la connecter \u00e0 mon r\u00e9seau pour les notifications et le contr\u00f4le\".<\/p>\n\n\n\n<p>Je le fais chaque semaine. Si vous \u00eates comme moi, ce projet est fait pour vous !<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"587\" height=\"620\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/Screenshot-from-2023-11-30-13-17-49-edited.png\" alt=\"\" class=\"wp-image-6315\" style=\"width:475px;height:auto\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/Screenshot-from-2023-11-30-13-17-49-edited.png 587w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/Screenshot-from-2023-11-30-13-17-49-edited-284x300.png 284w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/Screenshot-from-2023-11-30-13-17-49-edited-11x12.png 11w\" sizes=\"auto, (max-width: 587px) 100vw, 587px\" \/><figcaption class=\"wp-element-caption\">Cr\u00e9dit : <a href=\"https:\/\/andybradford.dev\/2021\/11\/23\/hacking-some-smarts-into-a-basic-coffee-machine\/\">Andy Bradford<\/a>.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>Andy fait pr\u00e9c\u00e9der le message de l'information suivante : \"Ce billet est publi\u00e9 \u00e0 titre d'information uniquement. Il ne s'agit pas d'un guide. N'essayez pas vous-m\u00eame.<strong> <\/strong>Si tu demandes de l'aide, je ne pourrai pas t'en donner\".<\/p>\n\n\n\n<p>Je suppose donc que vous devez vous d\u00e9brouiller tout seul si vous voulez poursuivre un projet similaire. N\u00e9anmoins, je pense qu'il s'agit d'un petit hack \u00e0 la fois utile et g\u00e9nial. Andy a partag\u00e9 le code sur <a href=\"https:\/\/github.com\/andycb\/VerveCoffeeMachine\">GitHub<\/a> sous licence MIT.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Mat\u00e9riel informatique<\/h2>\n\n\n\n<p>Andy a d\u00e9mont\u00e9 la machine \u00e0 caf\u00e9 et d\u00e9couvert qu'elle repose sur deux cartes : l'une s'occupe de la commutation haute tension, tandis que l'autre est un microcontr\u00f4leur qui g\u00e8re toutes les autres fonctions importantes.<\/p>\n\n\n\n<p>Ce projet repose donc sur la manipulation du microcontr\u00f4leur de la machine \u00e0 caf\u00e9. Le microcontr\u00f4leur doit prendre le contr\u00f4le afin de d\u00e9cider de la force du caf\u00e9, du maintien au chaud ou non, de la pr\u00e9paration du caf\u00e9 et de l'envoi d'un message lorsque le caf\u00e9 est pr\u00eat.<\/p>\n\n\n\n<p>Ici, Andy a opt\u00e9 pour un <a href=\"https:\/\/buyzero.de\/products\/adafruit-feather-huzzah-with-esp8266-loose-headers\">Adafruit Huzzah ESP8266<\/a> (mais vous pouvez d\u00e9sormais obtenir un <a href=\"https:\/\/buyzero.de\/products\/assembled-adafruit-huzzah32-esp32-feather-board-verschiedene-varianten\">Adafruit Huzzah ESP32<\/a>qui est une version mise \u00e0 jour).<\/p>\n\n\n\n<p>Andy a utilis\u00e9 une cafeti\u00e8re \u00e0 filtre Morphy Richards Verve. Les informations sur le projet sont donc sp\u00e9cifiques \u00e0 cette cafeti\u00e8re :<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"985\" height=\"823\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-29.png\" alt=\"\" class=\"wp-image-6319\" style=\"width:475px;height:auto\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-29.png 985w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-29-300x251.png 300w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-29-768x642.png 768w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-29-14x12.png 14w\" sizes=\"auto, (max-width: 985px) 100vw, 985px\" \/><figcaption class=\"wp-element-caption\">Cr\u00e9dit : <a href=\"https:\/\/www.morphyrichards.com.au\/en-au\/verve-filtered-coffee-maker#163005\">Morphy Richards<\/a>.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>Mais avec un peu d'ing\u00e9niosit\u00e9, il est certainement possible de faire quelque chose de ce genre avec de nombreuses cafeti\u00e8res \u00e9lectriques, si ce n'est la plupart d'entre elles.<\/p>\n\n\n\n<p>Andy mentionne que l'alimentation 5V de la machine \u00e0 caf\u00e9 n'\u00e9tait pas assez puissante pour alimenter le Huzzah. Un c\u00e2ble USB s\u00e9par\u00e9 s'est donc av\u00e9r\u00e9 n\u00e9cessaire pour alimenter la carte.<\/p>\n\n\n\n<p>Il a suffi \u00e0 Andy de d\u00e9couper un trou sur le c\u00f4t\u00e9 de la machine \u00e0 caf\u00e9 et d'y fixer un Veroboard. Le Veroboard maintient le Huzzah, le circuit et les r\u00e9sistances en place \u00e0 l'int\u00e9rieur de la machine \u00e0 caf\u00e9. <\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"577\" height=\"414\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-27.png\" alt=\"\" class=\"wp-image-6316\" style=\"width:475px\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-27.png 577w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-27-300x215.png 300w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/image-27-18x12.png 18w\" sizes=\"auto, (max-width: 577px) 100vw, 577px\" \/><figcaption class=\"wp-element-caption\">Cr\u00e9dit : <a href=\"https:\/\/andybradford.dev\/2021\/11\/23\/hacking-some-smarts-into-a-basic-coffee-machine\/\">Andy Bradford<\/a>.<\/figcaption><\/figure>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Logiciel<\/h2>\n\n\n\n<p>Pour ce faire, Andy a utilis\u00e9 l'IDE Arduino.<\/p>\n\n\n\n<p>L'auto-d\u00e9couverte MQTT, qui est une extension construite sur le protocole MQTT.
