Today I want to tell you about how you can make an epidemioscope yourself - a device for projecting small images onto a large screen ...
To start, I suggest you watch our video homemade:

It happens that you need to enlarge a small image and there is no way to do it using technologies such as a computer ... Today in this article I want to tell you how it was done before, without a computer and various modern technologies ...
So, for our homemade work, we need the following:
- a magnifying glass (magnifier) or a lens from an old diascope;
- wooden square with mounts for the lens;
- a can of beer;
- a bulb with a wire and a switch ...
So, let's begin...
First you need to make a square made of wood ... To do this, measure 90 degrees and carefully fix two wooden boards to each other at an angle of 90 degrees ... On the square, which we got, we attach the mounts for the lens and for the beer can, which will serve us as a guide for the light ...
Next, we attach the lens from the old diascope to the mounts ...
We put the image (in our case this is a photo inverted opposite the lens ...
Next, we make a hole in the beer cans and fix the light inside ... Now carefully attach it to our square so that the light stream from the light falls on the photo ...
That's all! Our projection device is ready ... Now we will test it ... To do this, turn off the light in the room and create darkness ...
After that, turn on the light bulb, put a white sheet opposite the lens and, adjusting the lens itself, an enlarged projection of our photo appears on a sheet of paper ...
So, with the help of improvised tools, we just made an epidemioscope - a device for projecting a small image onto a large screen ...
Good luck !!!
