I know this isn’t the most informative post, but a lot of the IT guys in our operations unit do a lot of DIY “home-improvement” projects. It’s stuff like controlling lights, automated blinds, monitoring their indoor plants,3D printing tools for their expensive bikes.
It’s all self-made and most of it is self programmed and hosted on whatever hack solutions they use, and they mainly use YouTube videos for DIY electronics to make it happen.
Like I said, not that informative for a HN reply, but I would start there.
