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.

To use a simple usb webcam as a microscope, only a few modifications are needed. Also, A Software That Control The Focus Of Specimen Using Small Servo Motor.

Duration
4 Day

Targeted age group
all

Step 2: Get A Webcam

You can experiment with different products. High resolution cams will make you see more clear details of what you want to see with your own microscope.

Step 3: Disassemble The Webcam : Step 1

Gently remove the cover from the webcam. Usually it's screwed with one or two screws but most of the time you will find it's not so you can just try to remove it .you will know you are doing it right when you hear it clicking but make sure you are not breaking the webcam circuit inside and watch out the lens.

Step 4: Step 2

After you open it , make sure not to unplug or cut any wires . Make sure that you remove any screws attached to the webcam's circuit.

Step 5: Step 3

Now You have got yourself your own microscope camera but still not yet ready to view Micro-stuff. Make sure that you don't cut any wires while moving the circuit so the microscope works fine with no problems.

Step 6: Remove Webcam's Lens

Remove the Webcam's Lens. It's obviously located at the center and this should be easy to do.

Step 7: Invert The Lens

Invert The Lens (Put it up side down) and fix it back on the webcam's circuit center (CMOS Sensor).

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
