Turn a Raspberry Pi into an Astrophotography Autoguider

I hate when my images turn out like this:

You can barely see the Crab Nebula drifting through the frame because I didn't align my mount well. To keep my telescope fixed on an object during long exposures, I needed an autoguider. But I also hate having a laptop in the field, which is required for most autoguiding solutions. To avoid this burdensome piece of equipment, I turned a Raspberry Pi with a touchscreen case into an on-board autoguiding system for my astrophotography rig.
