Setup

This site runs on Jekyll, an opensource static site generating platform.

  • Clone or download a zip of this project to your computer and navigate to the project directory in your terminal

NB: Current versions of github pages works with ruby 3.2.x and Jekyll 3.9.3 ! Make sure you install THESE versions!

  • Make sure Ruby is installed, to check if it is, run:

    text
    ruby -v

    For more information about installing Ruby, refer to the Ruby installation .

  • Install the Jekyll and bundler gems from the commandline:

    text
    gem install jekyll bundler

    For more information about installing Jekyll, refer to the Jekyll quickstart guide

    A specific version of jekyll can be installed via:

    text
    gem install jekyll -v 3.9.3
  • Some problems may occur if the bundler gem file is updated, but the Gemfile.lock still contains a reference to the old version. This can be solved by:

    text
    bundle update --bundler

    Sometimes other gem packages also need to be updated: see the Gemfile for possible updates (like: bundle update github-pages).

  • Install Gem dependencies for the project by running:

    text
    bundle install
  • To run the server in your local environment run:

    text
    bundle exec jekyll serve
  • Go to http://localhost:4000/ in your browser

Github.io native operation

Nothing is needed! Just make changes to the source, and everything will be published.

The only reason to use a local server and a local build is for testing, it is not necessary for publication on github.io.

Questions

What parts does the Calendar use?

8 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Calendar KiCad files?

From the architolk/architolk.github.io repository on GitHub, at the commit this page was made from: the board is assets/kicad/calendar/calendar/calendar.kicad_pcb and its schematic assets/kicad/calendar/calendar/calendar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Calendar design in my own project?

Its repository states no licence, so its author keeps all rights: ask architolk before reusing the design.
