If you’ve got a spare wall somewhere in your home that you’re not sure how to decorate, grab a bucket of glow-in-the-dark paint and slap some on. Lower the lights, grab some UV-LED flashlights and start drawing.
PaulBo over at Fangletronics came up with the idea as a way to entertain his kids but we’re pretty sure this is cool enough to amuse just about anyone. As long as you have white or very light-colored walls, your paint job won’t be particularly noticeable so you might even able to get away with this little project if you’re renting your abode.
The painting process is pretty simple:
We isolated a good amount of wall with painters tape, we just wanted it to be slightly taller than the kids. Then we put on 2 coats of white primer, 3 coats of the glow-in-the-dark paint and a couple of layers of varnish (so the kids didn’t immediately scrape off the latex based glow paint). After removing the painters tape, I was pleasantly surprised to see that the wall didn’t look much different.
Once the phosphorescent paint dries, there’s a couple of different things you can do with the wall. PaulBo walks you through how to hack together some small UV-LED light pens cobbled together from some small LED keychain flashlights, coin cell batteries, and a soldering iron. If you don’t want to hassle building them, then the LED flashlights will work fine but the glow just won’t last as long.
Another cool trick to make use of your fun new wall is to position people in front of the wall, then snap a picture with a flash camera. When they step away from the wall, their silhouettes will remain like giant shadow puppets. Spooky-cool.

If you’ve done a similar project of your own, or have other fun ways to make use of a glow-in-the-dark wall, we’d love to hear about it in the comments.

If you find yourself always tearing the wrinkled sheets off your bed to use as a makeshift projector screen, it’s time to upgrade. Make this portable screen on the cheap that stashes away in a closet til the next time you need it.
The DIY portable projector screen project over at Instructables can be whipped together in about an hour, and costs next to nothing to assemble. All you need is a white sheet, some eyelets, a few screw-in hooks, and about 12 feet of PVC pipe.
There’s only five steps involved in making the screen:
1. Decide what size you want. Mine is 5 feet wide by 6 feet tall.
2. Cut and sew the top and sides. Leave a couple inches extra on each side so you can fold it over and sew a seam.
3. Insert eyelets. One on each side of the top.
4. Sew in PVC pipe. This is to make it hang flat and straight, and to make it easy to roll up and store. Just fold the bottom over the PVC, crease the sheet, take out the pipe and sew all the way across. Then slide the pipe in and sew the sides shut.
5. Put the hooks in your ceiling. I put some in my living room, my bedroom, and another bedroom. They’re hardly noticeable so I just leave them up there all the time.
Using a bedsheet for this project is a super-inexpensive way to get the job done, and you can get them everywhere from Target to Goodwill. If you’re looking for a sturdier material, though, try using Tyvek in place of the sheet
If you’re feeling adventurous, you could cut the length of PVC pipe in half before sewing it into the sheet—then you can fold it in half before storing it. One of Instructable’s commenters also suggests adding a second piece of PVC pipe to the top edge for added stability, and to make sure the screen hangs straight.
How would you tweak this project to make it easier, or to make the screen even more user-friendly? Brainstorm in the comments.

The last time we talked NES hardware with you, it was a tip on how to repair a broken pin connector and get your old system working again. These hacks will take your old-school system to another level all together.
Over at Raphnet.net the personal site of a Linux and electronics enthusiast, Raph has put together a guide to moding your NES in all sorts of ways. His collection of guides covers everything from the simple—replacing the red LED with a blue one—to the complex like building your own reporgrammable NES cartridge to load with game ROMs. Some of his more clever hacks involve enabling stereo sound and a remote reset button. Check out the site for additional details, diagrams, and photos.
