Since I'm not a hardware guy, I try to avoid assembling my own gadgetry as much as possible on this project. I use consumer grade home automation modules, standard computer parts where possible. (Everything in my car is largely interconnected with USB.) And generally, experimenting with the NUC UPS aside, I try to avoid parts that may be hard to replace. Which is to say, I don't have time to build, test, and fix a random Arduino gadget. ;)

I've been planning to make some custom-cut USB cables and a 3D printed part just to make the setup of my display a lot cleaner... and I haven't done either of those and it's been a year or so since I planned to.
