Bismillah,Have you ever tried to take a close look of a plant or an ant? Though magnification glasses are able to do a little of magnification but they are not very close but now I am here with a hack which can easily penetrate your clothes or even you can see an antís eye structure because itís a microscope out of a simple camera or webcam. Isnít it Great! All you need is a simple but good picture quality camera or webcam.This Is very cheap project and even can be made from stuff around your house. So you must read it step by step to remake it the proper way. It is easy to make and any one can build without any specific skill. So get ready to make your own.And thank you for reading. If you want to stay tuned to me follow me and please vote for me in the Build my lab contest and Hardware hack contest that will be a great favor.
Step 1: Thechnical Know-How
Initially there is nothing of much worth. Basically a normal webcam has two parts one is: The PCB part with the CMOS sensor. (Exactly the PCB has a CMOS sensor mounted on it which receives the image from the lens and it projects a very tiny image on the CMOS.)The other part is the lens which receives the picture from the front side and the makes it very small at the other side so that it can be projected at the CMOS sensor. Now what we are doing right now is we just invert the lens (means upside down) and now install it on the CMOS sensor back again. Now the smaller side of the lens receives the image form outside and the bigger side projects it on the CMOS sensor.In this case the inverse happens the smaller side of the lens magnifies the image (which is outside or the object under observation) to a big level and the projects the magnified image to the CMOS sensor. This is the whole concept. Well what i used in this project is a bus security camera but now you know the concept it can be still applied in any camera or even webcam having a detachable lens.Though good camera has a good quality image but still you can use a cheap camera too.
IMPORTANT: Now there are two factors on which the quality of the image depends these are:
LightThere should be a proper light to watch the object this is also an important factor the lower the light the worse is the image quality.
Step 2: Stuff You Need
There are very few things you are going to need to build this project.
Some stuff you may need if any need comes.
Step 3: $Expense$
The one and the most expensive thing used in this project is a small camera or a webcam it may cost you around 30 - 40 $ and the other things are general tools and most of them must be available at home. I am making a list of materials which is used in this project they are:
Step 4: Making! (The main microscope.)
So here you go with the making!
Step: 1 :Open your cameraís casing and take out the PCB out of it with the lens because it may happen that the lens and the CMOS are not joined to each other by screws they may be held together by the casing itself.
Step: 2 : Now you have the PCB and the lens out of the casing . Observe the lens carefully in search of thread so that you can screw the lens out from the CMOS sensor secondary casing or if there is no thread there so maybe you can just pull it out from the CMOS sensor or it could be held by screws. Now take out the lens and remove the lens casing if any!
Step: 3 : Now you have the lens. You will see that the smaller side of the lens faces the CMOS sensor and the bigger captures image from outside. Now invert the lens position so that itís bigger side faces the CMOS sensor and now tight it to the casing inverted or if you donít have any inner casing the stick it out with hot glue and paint it so that the light wonít come in. Now you are half a way ready!
Step: 4 : Now you can plug it to your computer and test it by bringing it close to any object any then you will see a magnified view of that object. Now if you want you can make your own housing for
your microscope by steps given in the next step.
Step 5: MAKING THE OUTER CASING FOR MICROSCOPE.
Step 6: Working Video
Here is the working video of this microscope and it really works Great!
