Here’s a cool DIY on how to turn your rear projection TV (or DLPTV) into a 100-inch cinema screen by ripping the front of your TV and adding a bigger screen further away.

I do like it but I assume that the video quality will degrade when doing this so don’t blame me because everything gets bigger after this hack.

I bought Sony KDFE50A10 rear projection TV that has 50″ screen. After an year or so, I started to feel like the screen size is shrinking, really, ask any one who has a big screen TV. I wanted to buy a projector and have 100″ screen. But with more than $2500 already invested, the WAF (Wife Approval Factor) is zero. So, I have been thinking to convert this RPTV into a rear projector, but I couldn’t find any help on the net.

Wow, it looks like someone had to hook up all their old cellphones to an electric piano.  Each key on the piano responds to a dial button on one of those phones, creating a dial-tone.  Of course, there’s not enough dial-tones to cover all the notes.

The cell phone piano. Each key on the keyboard is wired into a key on a cell phone - as you play, you are also dialing. The channels are mixed together and amplified through speakers. Every sound the piano makes is generated by one of the four phones. The white keys play notes and the black keys are people saying the number out loud - English on the left hand and Spanish on the right. Some white keys were left over and I made those percussion instruments (the “*”, “END”, and “#” keys).

Whereever you live, you might wonder how you can add more privacy to your blind-less windows without spending a bunch of money.  You can get the acrylic glaze paint, which is really for walls but when you apply it to windows, you get a nice “glazy” windows as shown above.

Besides being cheap, this solution is also easily reversible simply by scraping off the glaze when you need to.

Why glaze? When you paint acrylic wall glaze that people use to apply tinted accents to their walls on glass it dries as a milky opaque film. Whatever pattern you brush, sponge, or roll onto the glass with the glaze stays there. To remove it all you need to do is scrape it with a stiff object like a credit card and it will flake off. If you want to remove it without the flakes you can wet it with a sponge first and after a few minutes you can peel it off like plastic sheet (even if it doesn’t come off as one big sheet, you can peel it easily in big strips). A full size glass sliding door in an old apartment was the first time I experimented with using acrylic glaze for privacy, when it came time to move out I was able to restore the sliding door to it’s previous state in a matter of minutes.
