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.

Step 1: Objective
Targeted age group
Step 2: Get A Webcam
Step 3: Disassemble The Webcam : Step 1
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.
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
Step 7: Invert The Lens
Step 8: Webcam Test
Step 9: DIY Microscope Design : 3D Modeling
Step 10: Design Assembly

Step 11: Laser Cutting
Step 12: Arduino Focus Adjustment : Step 1
We used (Turnigy TG9e 9g / 1.5kg / 0.10sec Eco Micro Servo) To Control The Distance between the slide that we want to see under the Microscope and the webcam. Fix the Micro Servo at one side of the microscope kit using Hot Glue or you can laser cut a small holder for the motor if you want. The Micro Servo Motor can be controlled using Arduino Uno.
