Introduction

We used a simple cheap webcam to make a microscope. In short, a small hack to the optics of a standard webcam with an adjustable focus-lens, allows to create video data, with a magnification of around 100 to 400x (depending on the model) at a working distance of a few mm. The highest magnifications can be achieved by inverting (putting upside down) the lens. We used white LEDs at first but the picture wasn't clear enough ,so we used A Flash Light for brighter and more clear view.

Really cool project guys! I made a similar diy webcam microscope w/ 3-axis stage based on cams and those little blue servos you uses. https://www.flickr.com/photos/macowell/4981452602/...

Recently I saw these tiny "ultra micro linear servo" units on RC helicopters. They actuate the swash plate. My experience w/ the blue micro servos was that they had a lot of jerk and backlash. I suspect these swashplate micro linear servos may perform more smoothly and eliminate the necessity of cutting a cam.

Example of linear servo:

Why do you invert the lens?

That looks great. If you make a duplicate circuit diagram using 123D Circuits, you'd be eligible to win the special judge's prize in the Circuits Contest. (I mean, you're still eligible to win the other prizes, but the fine folks at 123D are pretty excited to see people use their free Fritzing equivalent._

Thanks for your support and I tried to do it with 123D Circuits but i think there's a problem especially using firefox so i used Fritzing
