For context since it's not mentioned on the website: This is a project by n-o-d-e[1], they make blog posts and videos about diy tech/mods. This specific project is described in [2].
They also have techno-optimistic YouTube channels that I love. There haven't been any new videos for a while, but some of the older ones are worth watching:
