On second week, we showed how to built a microscope based on a webcam. In the way, we learned our own lessons.
First lesson: Light. Microscopes needs light. So, if you aere going to buy one, try to look for one with some white leds. Also, you can add 1 or to of them in a more or less sophisticated way.

Second, disassemble the webcam. Most of them just have 1 bolt and are easy to open. Other require more brute force…
Second lesson: Logitech webcam are hard/tricky.
Once you get the electronics free, remove the lens carefully.
Third lesson: Lenses, the wider the better. We found that was easier to fit
