Usb Microscope

thingiverse

I've made a USB microscope from an old Soviet-era camera lens with M42 mount and an older webcam. The idea of making a USB microscope for SMD soldering has been on my mind for some time now, but I wasn't happy with the price/quality ratio and the distance from the PCB when set up. So, I decided to take the hacker's way and use what was lying around in a junk box. I've used one M5 threaded rod, some nuts, washers, and a wooden board. One webcam. And one camera lens. Here is the parts list I printed: - The lens - camera ring adapter (you should model it for your own camera/lens models) - Clamp for holding camera with lens vertically - Nut wings for easy tightening - 90 degree arm mount - to mount the camera I also found that you can reverse an original web-camera lens for macro photography, but I found the focusing distances unusable. The red box in the third photo marks the place where I took the second photo (through microscope). UPDATE: Now I've mounted a lens (K mount) from my old Pentax camera. It's easier to focus and gives me a bit sharper image. I'm adding STL and Fusion 360 files (for modification). The last PCB closeup was made with this lens. Print Settings: - Printer Brand: RepRap - Printer: Prusa i3 - Rafts: No - Supports: No - Resolution: 0.2 - Infill: 40% - Notes: All parts printed without supports with 40% infill. This should be enough to hold things firmly. Post-Printing: Insert nuts in the wings using pliers as the fitting is quite tight to hold nut firmly.
