This build was originally inspired by the LEGO X-Pod sets. While trying to find a use for the pod itself, I realized that it was very close to a deep petri dish. I used a planetary gear system to allow both coarse and fine adjustment of the objective “lens”. A little more tinkering and I connected the focus to a magnifying glass and fiber optic light in the eyepiece, so adjusting the focus knobs would actually bring the writing on a LEGO stud in and out of focus.
