Perhaps the best implementation of marrying a Raspberry Pi and an old monitor is the PiClock. When one developer had free time on a Saturday afternoon, he built the wonderful gadget you see above. And like any good developer with a Pi, he made the whole thing open-source, so anyone can build their own.

The PiClock displays the time through a simple clock, the weather forecast in your area, and also a radar map. Because who doesn’t need to check a radar map at all times?

There’s a step-by-step guide for everything you need, but it’s really nothing more than the monitor, the Pi, and the power supply. A keyboard and mouse will be needed for setup, as well as an active Wi-Fi connection, but then you’re done.

Hack It Into a “Your-Eyes-Only” Monitor

Sometimes, you’re working on something private in an open office, or browsing certain *cough* sites *cough* at home. You can’t have your colleagues or kids see what’s on the screen. To keep snooping eyes at bay, make a “your-eyes-only” monitor from an old one.

To anyone else, it is going to look like a blank white monitor with nothing on it. But wearing a special pair of spectacles, you’ll be able to see things on it like a regular monitor. It’s magic! Here’s what it looks like and the process:

Basically, you will be cutting out the polarizing film of the monitor. This film will then be put on a simple pair of glasses. Now your screen appears white, but the glasses can “see” the content. It’s one of the best ways to keep prying eyes out of your PC Keep Out Prying Eyes With A Computer Privacy Screen Keep Out Prying Eyes With A Computer Privacy Screen Are your co-workers paying too much attention to your display? A privacy screen can help – here are your options. Read More .

The reason you should use an old monitor is that things can go wrong. You will be disassembling and then reassembling the monitor, along with cutting out the anti-glare and polarizing films. You’ll also need to separate the polarizing film from the anti-glare one. It’s a tough process, but dimovi’s guide at Instructables is thorough and precise. Just remember, while others can’t see what’s on your screen, they can still see where your hands are.

Turn It Into a Mirror (or a Smart Mirror)

If you have a broken old LCD monitor, it can be re-purposed into a usable mirror; but if you have a working old LCD monitor, adding a Raspberry Pi can turn it into a smart magic mirror 6 Best Raspberry Pi Smart Mirror Projects We've Seen So Far 6 Best Raspberry Pi Smart Mirror Projects We've Seen So Far The magic mirror of the future won't just say you're the prettiest of them all. It'll also tell you the time, date, weather outside, upcoming calendar appointments, and more. Read More !

The simpler of the two is the plain mirror. Instructables user MrAdventure put together a simple guide for it. Just get a screwdriver and open up your monitor. Strip out all the parts, you just need the screen. As he puts it poetically:

The LCD has several layers. Find the shiny part and make it point outwards, the better to see your beautiful face with! Now screw it back together in a few places so the frame holds all the guts in.

You can then put the screen back into the monitor case if you want a desk mirror. Otherwise, just hang this thing on a wall.

If you’ve got a little more time and are up for a more intense DIY project, then try the MirrorMirror smart mirror project. Blogger Dylan Pierce documented every step of his project to make a gorgeous smart mirror with a wooden frame.

You’ll need some additional material for this one, including a Raspberry Pi, a double-sided mirror, 2×4 wooden bars, cables and woodworking tools. If you do it right, you’ll end up with a beautiful smart mirror like the one above. Girlfriend not included, nerds.

    One of my favorite ways of disposing off old electronics is to give them away to the local electronics school. The students and teachers there may have use for the parts that are still working (and many of them do work).
