You can buy them wherever you buy your daily dose of electronics. I list them because that’s where I got the parts from. Note: I have no affiliation with the listed vendors. I will however link each post back into this one in the correct order, so you’d be able to just click on the link and jump straight to that specific post.
I will try to keep things in order but that’s no guarantee. What will follow this post will be a series of steps to go from taking a brand new raspberry Pi 3 out of the box to having MagicMirror² up and running.
