space.api

The Space API endpoint for the Amman Valley MakerSpace, switched on and off with a big sign that is also a switch.

• You can see a description of how to setup the MyHackerspace app.
• You can fork this repository to set up a Raspberry Pi based HackerSpace status for your own space.

Usage

If the button is on or off, the scripts will upload the current status. Since the scripts run each minute once, see crontab and GitHub refreshes the page every 5 minutes, it can take up to 6 minutes until an update arrives on the website.

1. Head over to f-droid.org.
2. Download the F-Droid app and install it.

   2. Choose Widgets
   3. Choose MyHackerspace

Status Image

The status image for the space can be found here:

Please copy the whole URL if you like to embed it:

Status Badge

If you would like to have a small badge displaying the status of the space, you can use this one:

Please copy the whole URL:

https://spaceapistatusimage.hosted.quelltext.eu/status?url=https%3A%2F%2Fraw.githubusercontent.com%2FAmmanVMS%2Fspace.api%2Fmain%2Fapi.json&open=https%3A%2F%2Fimg.shields.io%2Fbadge%2FMakerSpace-open-lightgreen&closed=https%3A%2F%2Fimg.shields.io%2Fbadge%2FMakerSpace-closed-red

The badge and the image were both created with the SpaceAPIStatusImage generator.

Setup For Your HackerSpace

You can set up your own Raspberry Pi to report the Hackerspace setup. This should walk you through how to do it.

1. Fork this repository.
2. Edit api.json to represent your own space.
   You can replace the workshop-closed.jpg and workshop-oepn.jpg images or just leave them out for the start. There is loads to customize. have a look at the documentation.
3. Follow the Server Installation described below.
4. Decide if you would like to setup GitHub Pages to serve the endpoint: Fork → Settings → GitHub Pages → choose branch → save. The endpoint should be avaliable under https://your_fork.github.io/space.api/app.json That might be faster than the raw representation which caches for a long time.
5. Check and include the raw-git/GitHub Pages URL to the api.json file for your repository’s api.json file. (Example)

Server Installation

The Raspberry Pi will update the status JSON automatically and push the current status to GitHub. GitHub serves as a reliable server for the data.

1. Install git.
2. Create SSH-Key.

    ssh-keygen
   

3. Add the ~/.ssh/id_rsa.pub as deploy key to the repo or add it to the GitHub account.
4. Clone the repo

    git clone git@github.com:AmmanVMS/space.api
    cd space.api
    git config --local user.email "pi@raspi"
    git config --local user.name "pi"
   

5. Add a minutely check with crontab -e: ```
   • • • • • /home/pi/space.api/check_status.job ```

Done. Now, the Raspberry Pi checks the status every minute and uploads it to GitHub. You can check if it works by reading the created log file.

Hardware setup

See Using Switch with Raspberry Pi – Python. You can also adjust the scripts.

You can edit the script to change whether a pressed switch means open or closed.

In our case, we also have an LED attached to the swicth so you know if it connects. Pins: black(5V) free red(GND) free free yellow(GPIO)

Checking the Status

To check the status, run the

./status.py
