DIY Microscope




This Project Is A Part Of The Afrimakers Event
http://www.afrimakers.org/
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.

Step 1: Objective

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.DIY Microscope

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:

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:

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).

Step 8: Webcam Test

Connect your webcam (a microscope now) to your pc or laptop and check to see if it still works or not, You won’t see anything but a blurry image which is totally normal at this point. Now we have to make a design for our DIY microscope. To view the webcam , you can use any webcam software like VideoLan (VLC), AMCap , macam, guvcview, …etc

Step 9: DIY Microscope Design : 3D Modeling

At first, We laser cut the Hackteria DIY Microscope Kit And It’s Avaliable Here : http://hackteria.org/wiki/index.php/Laser-cut_microscopy_stages After that we decided to make the Focus Adjustment made by Arduino so we can control it by software instead of manual control.DIY Microscope Schematic

Step 10: Design Assembly

You can Watch A Short Animation Video For Assembly Here

Step 11: Laser Cutting

While Laser Cutting The DIY Microscope Parts Download PDF Cut File Here : () You can Import the pdf in any vector program like Inkscape , CorelDraw,….etcAlso There’s A Picture Of Top Part (Flash Light Holder)

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.
