Ok, stumbled across this…though it might be helpful for those that might need some assistance seeing small components

I’ve been looking for a decent and cheap USB microscope for SMT soldering. Many of these 50-100$ Chinese microscopes have quite poor working distance, resolution and image quality so I thought to try make one by myself.
A webcam should work quite nicely as a camera sensor because they should work almost everywhere without fiddling with drivers or viewing programs. Logitech C270 is quite inexpensive and it have 1280×920 resolution. A bit of googling also revealed that it doesn’t have any too fancy autofocus features that could cause problems later. Estimating the delay between camera and monitor from internet reviews was quite hard but it seems to be in tolerable level.
Most incredible part… Total: ~ 63€ / 86$
And focal length is incredible…no more 3-4” of space…just look at how much room you would have to solder!
That’s a huge space to work with!!!
