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 -vFor more information about installing Ruby, refer to the Ruby installation .
-
Install the Jekyll and bundler gems from the commandline:
text gem install jekyll bundlerFor 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 --bundlerSometimes 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
How big is the The internet PCB?
It measures 66 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the The internet use?
35 parts, built around the BC547, BC557 and IRF9240. 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 The internet KiCad files?
From the architolk/architolk.github.io repository on GitHub, at the commit this page was made from: the board is assets/kicad/the-internet/the-internet/the-internet.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 The internet design in my own project?
Its repository states no licence, so its author keeps all rights: ask architolk before reusing the design.
