Hey there, welcome to your new home on the web!

Unlike social networks, this one is all yours. Publish your work on a custom domain, invite your audience to subscribe, send them new content by email newsletter, and offer premium subscriptions to generate sustainable recurring revenue to fund your work.

Ghost is an independent, open source app, which means you can customize absolutely everything. Inside the admin area, you'll find straightforward controls for changing themes, colors, navigation, logos and settings — so you can set your site up just how you like it. No technical knowledge required.

If you're feeling a little more adventurous, there's really no limit to what's possible. With just a little bit of HTML and CSS you can modify or build your very own theme from scratch, or connect to Zapier to explore advanced integrations. Advanced developers can go even further and build entirely custom workflows using the Ghost API.

This level of customization means that Ghost grows with you. It's easy to get started, but there's always another level of what's possible. So, you won't find yourself outgrowing the app in a few months time and wishing you'd chosen something more powerful!

For now, you're probably just wondering what to do first. To help get you going as quickly as possible, we've populated your site with starter content (like this post!) covering all the key concepts and features of the product.

You'll find an outline of all the different topics below, with links to each section so you can explore the parts that interest you most.

Once you're ready to begin publishing and want to clear out these starter posts, you can delete the "Ghost" staff user. Deleting an author will automatically remove all of their posts, leaving you with a clean blank canvas.

Your guide to Ghost

• Customizing your brand and site settings
• Writing & managing content, an advanced guide for creators
• Building your audience with subscriber signups
• Selling premium memberships with recurring revenue
• How to grow your business around an audience
• Setting up custom integrations and apps

If you get through all those and you're hungry for more, you can find an extensive library of content for creators over on the Ghost blog.

Getting help

If you need help, Ghost(Pro) customers can always reach our full-time support team by clicking on the Ghost(Pro) link inside their admin panel.

If you're a developer working with the codebase in a self-managed install, check out our developer community forum to chat with other users.

Have fun!

As discussed in the introduction post, one of the best things about Ghost is just how much you can customize to turn your site into something unique. Everything about your layout and design can be changed, so you're not stuck with yet another clone of a social network profile.

How far you want to go with customization is completely up to you, there's no right or wrong approach! The majority of people use one of Ghost's built-in themes to get started, and then progress to something more bespoke later on as their site grows.

The best way to get started is with Ghost's branding settings, where you can set up colors, images and logos to fit with your brand.

Any Ghost theme that's up to date and compatible with Ghost 4.0 and higher will reflect your branding settings in the preview window, so you can see what your site will look like as you experiment with different options.

When selecting an accent color, try to choose something which will contrast well with white text. Many themes will use your accent color as the background for buttons, headers and navigational elements. Vibrant colors with a darker hue tend to work best, as a general rule.

Installing Ghost themes

By default, new sites are created with Ghost's friendly publication theme, called Casper. Everything in Casper is optimized to work for the most common types of blog, newsletter and publication that people create with Ghost — so it's a perfect place to start.

However, there are hundreds of different themes available to install, so you can pick out a look and feel that suits you best.

Inside Ghost's theme settings you'll find 4 more official themes that can be directly installed and activated. Each theme is suited to slightly different use-cases.

• Casper (default) — Made for all sorts of blogs and newsletters
• Edition — A beautiful minimal template for newsletter authors
• Alto — A slick news/magazine style design for creators
• London — A light photography theme with a bold grid
• Ease — A library theme for organizing large content archives

And if none of those feel quite right, head on over to the Ghost Marketplace, where you'll find a huge variety of both free and premium themes.

Building something custom

Finally, if you want something completely bespoke for your site, you can always build a custom theme from scratch and upload it to your site.

Ghost's theming template files are very easy to work with, and can be picked up in the space of a few hours by anyone who has just a little bit of knowledge of HTML and CSS. Templates from other platforms can also be ported to Ghost with relatively little effort.

If you want to take a quick look at the theme syntax to see what it's like, you can browse through the files of the default Casper theme. We've added tons of inline code comments to make it easy to learn, and the structure is very readable.

{{#post}}
<article class="article {{post_class}}">

    <h1>{{title}}</h1>

    	<img src="{{feature_image}}" alt="Feature image" />
    {{/if}}
    
    {{content}}

</article>
{{/post}}

See? Not that scary! But still completely optional.

If you're interested in creating your own Ghost theme, check out our extensive theme documentation for a full guide to all the different template variables and helpers which are available.

Ghost comes with a best-in-class editor which does its very best to get out of the way, and let you focus on your content. Don't let its minimal looks fool you, though, beneath the surface lies a powerful editing toolset designed to accommodate the extensive needs of modern creators.

For many, the base canvas of the Ghost editor will feel familiar. You can start writing as you would expect, highlight content to access the toolbar you would expect, and generally use all of the keyboard shortcuts you would expect.

Our main focus in building the Ghost editor is to try and make as many things that you hope/expect might work: actually work.

• You can copy and paste raw content from web pages, and Ghost will do its best to correctly preserve the formatting.
• Pasting an image from your clipboard will upload inline.
• Pasting a social media URL will automatically create an embed.
• Highlight a word in the editor and paste a URL from your clipboard on top: Ghost will turn it into a link.
• You can also paste (or write!) Markdown and Ghost will usually be able to auto-convert it into fully editable, formatted content.

The goal, as much as possible, is for things to work so that you don't have to think so much about the editor. You won't find any disastrous "block builders" here, where you have to open 6 submenus and choose from 18 different but identical alignment options. That's not what Ghost is about.

What you will find though, is dynamic cards which allow you to embed rich media into your posts and create beautifully laid out stories.

Using cards

You can insert dynamic cards inside post content using the + button, which appears on new lines, or by typing / on a new line to trigger the card menu. Many of the choices are simple and intuitive, like bookmark cards, which allow you to create rich links with embedded structured data:

Open Subscription Platforms

A shared movement for independent subscription data.

Open Subscription Platforms

or embed cards which make it easy to insert content you want to share with your audience, from external services:

But, dig a little deeper, and you'll also find more advanced cards, like one that only shows up in email newsletters (great for personalized introductions) and a comprehensive set of specialized cards for different types of images and galleries.

Once you  start mixing text and image cards creatively, the whole narrative of the story changes. Suddenly, you're working in a new format.

As it turns out, sometimes pictures and a thousand words go together really well. Telling people a great story often has much more impact if they can feel, even for a moment, as though they were right there with you.

Galleries and image cards can be combined in so many different ways — the only limit is your imagination.

Build workflows with snippets

One of the most powerful features of the Ghost editor is the ability to create and re-use content snippets. If you've ever used an email client with a concept of saved replies then this will be immediately intuitive.

To create a snippet, select a piece of content in the editor that you'd like to re-use in future, then click on the snippet icon in the toolbar. Give your snippet a name, and you're all done. Now your snippet will be available from within the card menu, or you can search for it directly using the / command.

This works really well for saving images you might want to use often, like a company logo or team photo, links to resources you find yourself often linking to, or introductions and passages that you want to remember.

You can even build entire post templates or outlines to create a quick, re-usable workflow for publishing over time. Or build custom design elements for your post with an HTML card, and use a snippet to insert it.

Once you get a few useful snippets set up, it's difficult to go back to the old way of diving through media libraries and trawling for that one thing you know you used somewhere that one time.

Publishing and newsletters the easy way

When you're ready to publish, Ghost makes it as simple as possible to deliver your new post to all your existing members. Just hit the Preview link and you'll get a chance to see what your content looks like on Web, Mobile, Email and Social.

You can send yourself a test newsletter to make sure everything looks good in your email client, and then hit the Publish button to decide who to deliver it to.

Ghost comes with a streamlined, optimized email newsletter template that has settings built-in for you to customize the colors and typography. We've spent countless hours refining the template to make sure it works great across all email clients, and performs well for email deliverability.

So, you don't need to fight the awful process of building a custom email template from scratch. It's all done already!

The Ghost editor is powerful enough to do whatever you want it to do. With a little exploration, you'll be up and running in no time.

What sets Ghost apart from other products is that you can publish content and grow your audience using the same platform. Rather than just endlessly posting and hoping someone is listening, you can track real signups against your work and have them subscribe to be notified of future posts. The feature that makes all this possible is called Portal.

Portal is an embedded interface for your audience to sign up to your site. It works on every Ghost site, with every theme, and for any type of publisher.

You can customize the design, content and settings of Portal to suit your site, whether you just want people to sign up to your newsletter — or you're running a full premium publication with user sign-ins and private content.

Once people sign up to your site, they'll receive an email confirmation with a link to click. The link acts as an automatic sign-in, so subscribers will be automatically signed-in to your site when they click on it. There are a couple of interesting angles to this:

Because subscribers are automatically able to sign in and out of your site as registered members: You can (optionally) restrict access to posts and pages depending on whether people are signed-in or not. So if you want to publish some posts for free, but keep some really great stuff for members-only, this can be a great draw to encourage people to sign up!

Ghost members sign in using email authentication links, so there are no passwords for people to set or forget. You can turn any list of email subscribers into a database of registered members who can sign in to your site. Like magic.

Portal makes all of this possible, and it appears by default as a floating button in the bottom-right corner of your site. When people are logged out, clicking it will open a sign-up/sign-in window. When members are logged in, clicking the Portal button will open the account menu where they can edit their name, email, and subscription settings.

The floating Portal button is completely optional. If you prefer, you can add manual links to your content, navigation, or theme to trigger it instead.

Like this! Sign up here

As you start to grow your registered audience, you'll be able to get a sense of who you're publishing for and where those people are coming from. Best of all: You'll have a straightforward, reliable way to connect with people who enjoy your work.

Social networks go in and out of fashion all the time. Email addresses are timeless.

Growing your audience is valuable no matter what type of site you run, but if your content is your business, then you might also be interested in setting up premium subscriptions.

For creators and aspiring entrepreneurs looking to generate a sustainable recurring revenue stream from their creative work, Ghost has built-in payments allowing you to create a subscription commerce business.

Connect your Stripe account to Ghost, and you'll be able to quickly and easily create monthly and yearly premium plans for members to subscribe to, as well as complimentary plans for friends and family.

Ghost takes 0% payment fees, so everything you make is yours to keep!

Using subscriptions, you can build an independent media business like Stratechery, The Information, or The Browser.

The creator economy is just getting started, and Ghost allows you to build something based on technology that you own and control.

Most successful subscription businesses publish a mix of free and paid posts to attract a new audience, and upsell the most loyal members to a premium offering. You can also mix different access levels within the same post, showing a free preview to logged out members and then, right when you're ready for a cliffhanger, that's a good time to...

As you grow, you'll probably want to start inviting team members and collaborators to your site. Ghost has a number of different user roles for your team:

Contributors
This is the base user level in Ghost. Contributors can create and edit their own draft posts, but they are unable to edit drafts of others or publish posts. Contributors are untrusted users with the most basic access to your publication.

Authors
Authors are the 2nd user level in Ghost. Authors can write, edit and publish their own posts. Authors are trusted users. If you don't trust users to be allowed to publish their own posts, they should be set as Contributors.

Editors
Editors are the 3rd user level in Ghost. Editors can do everything that an Author can do, but they can also edit and publish the posts of others - as well as their own. Editors can also invite new Contributors & Authors to the site.

Administrators
The top user level in Ghost is Administrator. Again, administrators can do everything that Authors and Editors can do, but they can also edit all site settings and data, not just content. Additionally, administrators have full access to invite, manage or remove any other user of the site.

The Owner
There is only ever one owner of a Ghost site. The owner is a special user which has all the same permissions as an Administrator, but with two exceptions: The Owner can never be deleted. And in some circumstances the owner will have access to additional special settings if applicable. For example: billing details, if using Ghost(Pro).

Ask all of your users to fill out their user profiles, including bio and social links. These will populate rich structured data for posts and generally create more opportunities for themes to fully populate their design.

It's possible to extend your Ghost site and connect it with hundreds of the most popular apps and tools using integrations.

Whether you need to automatically publish new posts on social media, connect your favorite analytics tool, sync your community or embed forms into your content — our integrations library has got it all covered with hundreds of integration tutorials.

Many integrations are as simple as inserting an embed by pasting a link, or copying a snippet of code directly from an app and pasting it into Ghost. Our integration tutorials are used by creators of all kinds to get apps and integrations up and running in no time — no technical knowledge required.

Zapier

Zapier is a no-code tool that allows you to build powerful automations, and our official integration allows you to connect your Ghost site to more than 1,000 external services.

Example: When someone new subscribes to a newsletter on a Ghost site (Trigger) then the contact information is automatically pushed into MailChimp (Action).

Here's a few of the most popular automation templates:

Custom integrations

For more advanced automation, it's possible to create custom Ghost integrations with dedicated API keys from the Integrations page within Ghost Admin.

These custom integrations allow you to use the Ghost API without needing to write code, and create powerful workflows such as sending content from your favorite desktop editor into Ghost as a new draft.

Objectif: image OTA ESP32-CAM

• BLE: pour envoie des photos à intervalle et/ou activation externe.
• Wifi: OTA.
• Server Web: configuration et ajustement de l'image
• Batterie Li/Po, mesure courant, régulation & recharge
• Activation de la LED si éclairage faible ou action
• Mode DeepSleep
• PIR: Détection et sortie du mode veille

Le sketch fourni par défaut dans Arduino IDE,  développé par Expressif, ne permet pas de créer une image OTA, ie. flashable à distance via Wifi, et donc plus pratique que via USB.

En effet OTA faisant cohabiter ancienne et nouvelle version des sketchs en mémoire, il faut donc disposer d'une RAM disponible deux fois plus grande que celle du sketch à uploader.

Ici la taille maximale serait logiquement de 2Mo (4Mo RAM sur esp32-cam => 4 / 2 = 2 Mo).

Le sketch par défaut (+ gestion OTA) dépasse largement ces 2Mo (168%).

Cependant, des tentatives existent pour diminuer son empreinte mémoire, notamment en supprimant la partie IA de reconnaissance de visage, inutile dans certains projets.

Malgré cela, il reste difficile d'activer plusieurs fonctionnalités ensemble OTA, serveur WebCam, Wifi, BLE...

Depuis le début 2020 certains projets semblent avoir relever le challenge... A tester...

DYI ESP8266, RFID + mini station météo

Mon projet: lecteur de carte RFID (MFRC522) + mini station météo (température et humidité), sur un module ESP8266 (ESP8266 D1 Mini NodeMcu).

Plusieurs possibilités de choix de module ESP8266. Dans les modèles les plus récents on peut également opter pour un ESP32 une évolution des premiers ESP.

Fonctionnalités supplémentaires:

• Utiliser un module DHT11 de mesure de température et d'humidité. A intervalle régulier l'ESP8266 sort de son hibernatiopn (deesleep), pour mesurer et envoyer la température par appel de webservice.
• Mesure du Voltage à la sortie de la batterie, en utilisant un diviseur de pont afin de mesurer une tension supérieure, à la tension maximale mesurable en entrée des GPIO analogique A0. Mesurer la tension d'une batterie ou pile (Arduino, ESP8266)
• Ajout d'un panneau solaire pour recharge

Montage

//TODO ajouter un schéma du montage

Description du montage

1. DHT11, ajout de pullup qui permet de maintenir le module dans un état à faible consommation, celui-ci étant activé par une séquence à l'état bas Explication complète DHT11. Pour plus de précision on pourra utiliser un DHT22, un peu plus onéreux. Le composant consomme 0,5mA et 2,5mA pour les modes respectifs de veille et prise de mesure.

Programmation

1. Mise à jour Arduino IDE, afin de prende en compte l'ESP8266.
   Pour cela il faut charger les bibliothèques:
   explication du montage

2. Installer et mettre à jour la bibliothèque MFRC522, directement depuis les menus de l'IDE Arduino. Cela m'a permis de résoudre une erreur d'initialisation de la carte (Firmware 0xDE non reconnu).

Doc. utile MFRC522

Pour la prog via Arduino ide,

Pour moi, suite à la lecture de plusieurs documentations, je suis tombé sur la configuration suivante, pour

Code utilisé :

Configuration des PIN

Mode d'interruption à configurer afin de limiter la consommation de l'engin. Idéalement, le passage de la carte sur le lecteur réveil, le module et l'ESP8266.

Un complément du montage est de communiquer le numéro de la carte à un webservice distant, pour activer une action (inscription dans une log, ouverture d'une porte, désactiver une alarme). Cette communication est possible par le module Wifi intégré dans l'ESP8266.
Cela lui permet de se comporter en serveur par l'exposition d'un point d'accès, ou bien en client en se connectant à un réseau Wifi.

Mode DeepSleep

Double sortie de du deepSleep, soit par bouton, soit par timer. Pour cela le Pin Reset doit être connecté au PIN 16 (vérifier le numéro), et au bouton effectuant le passage au mode Low.

Une led indique le mode activation en cours.
ETeint: mode DeepSleep, alumé => mode en attente de badgeage, et clignotant, en cours de démarrage.
Pb en mode deepSleep l'esp8266, repasse les PIN dans un état intermédiaire, ie., allumé faiblement. Pour réduire la consommation ajout de deux résistances, le moins de la led avec une valeur de 27Kohms, et le pull-down de 2,7k ohms.
Remède: En fait pour éviter ce problème il suffit de brancher la led à un pin bénéficiant d'un mode pull-down sur l'ESP8266, com' par exemple le pin D8 (cf, Doc du mini Wemos

Questions en cours

• Comment mesurer l'ampérage consommé en mode "deeSleep", sachant que les composants "RDC", ont une marge d'erreur d'environ 13mA, alors que je souhaite mesurer des microAmp? Plusieurs tentatives infructueuse avec mon ampèremétre.
• Pourquoi la mesure de la tension de la batterie me retourne une valeur en dessous de celle mesurée directement aux bornes de la batterie, ou lorsque l'esp est alimenté par USB 5V. 3,8V au lieu de 4,1V réel? Cela est-il du à une chute de tension lors de la prise de mesure, ou des résistances mal choisies pour le pont diviseur de tension (1K Ohms actuellement). Plusieurs valeurs supérieurs de resistance semblaient encore plus pénalisantes, malgrès les conseils lus dans le forum de la doc du diviseur de tension en référence dans ce billet.
• Comment utiliser des leds sur des ports GPIO sans qu'ils soient alumés en mode deepSleep. Lors des 1er tests, ils semblerait que les ports reviennent dans un état intermédiaire => les faiblement alimentées.
  -> Solution: utiliser un port ayant un état défini, en Pull-down. Voir les specs. de l'esp utilisé
• Comment calculer les résistances à utiliser avec le bouton de reset. Ce dernier permettant de sortir de l'état deepSleep, pour badger par exemple.

Améliorations à prévoir

De plus afin de rendre le module indépendant, et permettre par exemple la création d'un boitier externe non connecté à un réseau électrique, il faut penser à différents points:

• Voir si un régulateur à découpage DC-DC serait plus optimal pour le montage, sachant que le type de régulateur que j'utilise peut nécessiter une différence de potentiel non négligeable (ie au moins 1v volt de diff entre in et out pour fonctionner), et semble suivant la oc en lien moins performante que la DC-DC (>95% d'efficacité), la différence de tension étant transformée en chaleur et donc perdue.
• Boitier final étanche, et permettant d'avoir un bouton souple pour la sortie du mode deepsleep, un port de connexion pour mettre à jour le soft et recharger si nécessaire
• Plusieurs points de connexion Wifi en cas de panne de l'un d'eux
• Crypter les échanges avec le serveur notamment pour les codes RFID, et voir même pour les id de connexions Wifi.
• Meilleure gestion des Led et/ou bip sonore pour indiquer le mode de connexion.
• permettre le déclenchement du module raspberry en enregistrant les messages de lecture RFID dans une file de message.
