Speaking of making the most of what life hands you, here's a smart mouse hack I found on the RetroPie forum. For years, I've been trying to make my own arcade-style spinner on a slim budget, but this guy nails it, using a flanged pillow block ball bearing to get just the right distance between the mouse sensor and the bottom of the dial. Too much clearance and the sensor won't read what's above it; not enough clearance and the dial grinds instead of spinning freely. The ball bearing is designed to float a millimeter above wherever it's set, the sweet spot for a mouse sensor, and the assembly is made of metal, so there shouldn't be any of the sagging that foiled my previous attempt at building a spinner.
