Super-Spy Privacy Monitor Lets You Browse in Total Secrecy

It’s pretty safe to say that if you use a computer connected to the Internet, there have been at least a few times when you’ve been browsing on a page you’d rather the people around you didn’t see. Instructables user Dimovi turned an old LCD monitor into a “privacy monitor” that looks like a blank white screen to everyone except the user. Brilliant!

The process to make your own involves taking the monitor apart and removing the polarized film. This film is the magical ingredient since it allows only certain light waves to pass through and be seen. Removing it from the monitor and attaching it instead to some old sunglasses frames is the trick behind this particular hack.

This clever trick lets you browse in complete privacy since your monitor will always look blank to anyone not wearing the magic glasses. Of course, that means you can’t share the latest adorable cat video on YouTube with whoever happens to be in the room at the time, but it’s a small price to pay for absolute privacy.
