This DIY project hides your screen from everyone but you.

There are all kinds of things you might be viewing on your computer which you wouldn’t want a passerby to know about, like embarrassing titles in your Netflix queue, bank balances, job postings, and at home remedies to cure weird personal ailments. You could certainly purchase a privacy monitor from an electronics store; they’re pretty simple to attach but cost around $100, and odds are you probably have everything you need to make your own privacy monitor at home — one that would literally only be viewable by you.

The necessary materials are an old LCD monitor, superglue, paint thinner (or another solvent), paper towels, a screwdriver or drill, a pair of old glasses, and an x-acto knife or box cutter. If you follow the steps below, posted on Instructables by Dimovi, an electrical engineer based out of Austin, you can easily create your own privacy monitor. You’ll be free to have covert TV-watching and web surfing experiences in no time.

Step 1: Using a screwdriver or drill, unscrew your monitor screen from it’s frame.
Step 2: Cut the two films from the screen with your x-acto knife or box cutter. Feel free to ditch the frosted one, you’ll only need the polarized one, but be careful to remember the orientation of the screen (which side was facing the computer, which side is the top).
Step3: Apply the solvent to paper towel and place on screen to loosen left-over glue. Once it becomes soft, scrape it off with a piece of plastic.
Step 4: Put the frame back onto the monitor and screw it back shut.
Step 5: Take the lenses out of your glasses.
Step 6: Tape the lenses to the film (making sure the film is oriented just as it was on the monitor) and cut out the lense-sized portions of the screen. If you prefer, you can also have a laser cutting service do this for you.
Step 7: Glue the film to the lenses and put the lenses back into the glasses frame. Put the glasses on and look at the monitor, only the person wearing the glasses can see what’s on the screen.

So far, over a million people have viewed these instructions. According to the comments, other than the glue taking a while to soften, they work great. For a better idea of how these glasses work, check out the video below, then try to make them for yourself.
