“The purpose of this guide is to explain the basic principle of turning any webcam into a USB microscope.
For this proof of concept, i used an old 0,3Mpx Trust webcam (one of the worst webcam possible) and some 3D printed parts. I managed to get 1000X magnification (optical + numerical zoom) but the resolution is only 640x480. You can thus expect a much better images with a more modern webcam.
the operating principle is pretty simple :
- You take apart an old webcam- You recover the lens and flip it back- Put it back and with the help of magic optical principles you get a working microscope - Finally you just have to design and 3D print somes parts to hold your samples”
