Good timing! -- I hate filling a pill keeper but keep forgetting to take my dose, or forget if I DID already take my dose. So I made a gadget.

I took a 1"x1"x6" piece of wood, put S M T W R F S on the side, drilled 7 holes on top, and I use a thumb screw that I move when I've taken my pills today. A golf tee or nail would also work.
