DIY Forum Megathread

So I am creating this thread to be a melting pot of DIY ideas. It doesn’t necessarily have to be tech related either. The reason is because I am really interested in DIY. The thing that ultimately inspired this post was an article by Red Hat:

One thing that I’ve always wanted to do was make my own self-sustaining setup. I even want to build my own house - mostly because of the insane inflation of housing these days. I’ve also closely followed the tiny house movement for awhile. While I don’t particularly want to life in a space that small, I think they have great ideas that I can use to incorporate in my home - which I imagine as being a cabin on the banks of the Tennessee.
