Do you dream of seeing in the dark like a cat and remaining invisible to others? Night vision goggles will help to fulfill such a desire. This instrument is used in various fields, for example:
- for all kinds of search operations;
- for the professional activities of security guards, police, military and drivers who often have to repair equipment on the roads in complete darkness;
- for those who like to photograph or video wildlife at night.
Night vision goggles are required for hunting, fishing and tourism. Putting them on, you can quickly collect firewood in the dark to kindle a fire, freely pass through the thicket and not get lost in it, do not stumble over a tree root and do not fall into a hole. And these are only the main useful qualities of this device. This includes a huge number of other nuances. Night vision goggles can be bought in the store, however, they are very expensive. An alternative solution is to make them yourself at home. Try to recall your knowledge of chemistry and physics in your memory, and then it will be easier for you to understand how to make night vision goggles yourself. Find literature, readinformation, get ready.
Step by step
Take 2 glass plates and immerse them in a solution of potassium dichromate and sulfuric acid (for about 4 hours). Then dry the glasses and fix them over a porcelain cup at a height of at least 10 cm (you should put tin chloride in the container). Now place all this in a muffle furnace. Put a metal plate on the cup first.
Preheat the oven to a temperature of at least 470 degrees Celsius. Remove the plate quickly. Now carefully follow the changes that occur with the glasses. They will gradually begin to be covered with the thinnest film that conducts current.
Turn off the stove, let the glass cool down. Apply varnish to the side of the glass where there is no conductive film, and dip the glass in a solution of thiacarbamide and lead acetate. Then pour the alkali concentrate here, gently stirring the resulting liquid. After 15 minutes, carefully remove the glass from the cup. In the oven, put the same cup, but now pour the silver solution into it. Place glasses over it.
Preheat the oven to 900 degrees. A mirror film should gradually appear on the plate.
To obtain a colorless crystalline powder, mix copper and ZnS (10:100) in a cup and heat the mixture in an oven.
Take the Zapon varnish (for a binder) and mix with powder. Now drop this mixture onto the plate and let the drop spread. Make sure the coverage is even. Connect the two plates, squeezing slightly, dry them, and inat the end of the process, check the sealing of the resulting device. The night vision goggles are ready.
Don't forget to assemble the high voltage generator circuit!
Now it remains to connect everything. Take the lens for the device from the camera, and for the eyepiece - a biconvex lens.
After checking all the connections, you can start connecting. You will understand that everything is working fine by the characteristic squeak of the transformer.
For a clearer image, you need to change both the generator frequency and voltage levels several times. If you succeed, then go for night glasses visions you do not have to spend huge money buying them in the store.
