Building the machine was easy. I had an extra raspberry pi 4 laying around, and anytime I visit the Habitat for Humanity ReStore, or if I see one on the street I can't help but keep my eye peeled for a monitor or HDTV.

So I had an extra keyboard, corded mouse, and monitor lying around. Usually you can find these items for less than $40.00 all around.

On top of that I had an extra Raspberry Pi i can contribute. Right now I have 3 Raspberry Pi 4's in rotation and one Raspberry Pi W.

One of jack's favorite games to play on the computer is called Universe Sandbox.
