I built two Ferris Sweeps today, one for home, and one for the office. I originally intended to build one, but after I tested the first, I immediately decided I wanted to also use this at work.
I wasn't able to figure out how to align the switches better, so the grid is pretty bad looking. It doesn't impact my typing at all, so I've left it alone.
I think next time, I'll want some kind of case for it, I'm currently using cardboard, and the whole thing is kinda janky looking.
