How to digitize slides with a camera

Doing my best to keep myself busy while stuck at home, I decided to copy some old Kodachrome and Ektachrome slides with my DSLR and a flash. The idea was to set up a system where I could shoot tethered to my computer and go quickly through the slides. The results could be cropped and then shared with family and friends. I actually found some real gems in and among the awful photos I took as a teenager. It was rather fun.
