Sometimes we store files on a computer that are not visible to strangers. You can, of course, hide these files with the factory features that the computer operating system provides. However, these files cannot be completely hidden, since every second computer user can easily bypass this vulnerable protection. To avoid such an unpleasant situation, you can make an invisible monitor with your own hand, which will be visible only to the owner of special glasses.
So, for starters, let's see the video useful and amazing homemade:
What do we need?
- Old LCD monitor;
- Old glasses, of which we need only a frame;
- screwdriver;
- Stationery knife;
- Ruler.
An old monitor that we are ready to sacrifice has been found, which means that you can get to work. Remove all wires and screws from the back of the monitor. We disassemble the monitor so as to access the display.
As a rule, computer LCD monitors have a coating of two films - polarizing and anti-reflective. The first film is designed to filter light. There are monitors on which there is no anti-reflective film, like the author of the video. If it is present, then it needs to be put aside, since we will not need it.
When the monitor is fully accessible, we need to cut out the polarizing film with a clerical knife along the very edge.
Next, remove it with a ruler. Be sure to remember the orientation of the film - where is the top and where the bottom: this is very important. If you hold the film at different angles and look at the monitor, then the image at different angles will not always be in normal color.
After removing the film, a layer of glue will probably remain on the monitor, which will collect dust particles. The glue needs to be removed. To do this, give the adhesive a slight roughness so that the removal process is easier.
After that, take a triple cologne and cotton or paper towel and clean the surface of the monitor. As an alternative to cologne, you can use a solvent, but in this case you need to be extremely careful not to damage the monitor.
When the glue is removed, you need to assemble the monitor back.
Now you can start making glasses. To do this, take a marker and mark the size of the lenses of our frames.
Cut out the lenses with scissors or a clerical knife.
We install lenses on frames.
The glasses are ready, like our secret monitor. Looking at the turned-on monitor, everyone will see a static white image, except that he will look through special glasses made from the polarizing film of the monitor.
