HOW-TO: Make Noise Isolating Headphones

admin — Tue, 31 Jan 2012 15:43:00 +0000

You usually spend more that $100 for a set of noise isolating headphones so that you are not listening to any traffic noise or any other unwanted noise while playing your favorite number on your iPod. But it still will be much better if you can make one using household items and that too under $20. All you have to buy is some epoxy and stuff it carefully into your ears to get a mold of your ear canal. But, I warn you to please check if you are allergic to the material as if you are then you might end up having some days in a hospital. If you are not allergic to the material then you are good to go. Put some epoxy putty in your ear and wait for a couple of hours for the material to harden. Then carefully remove it from your ear and drill a hole in it and fix your headphones speaker elements in the mold and that’s all. Click Here for a detail tutorial. Thanks: natetrue Via: gizmodo

The Star Trek Homemade Theater by Gary Reighn

admin — Mon, 30 Jan 2012 15:42:00 +0000

the million-dollar Star Trek-like theaters featured in magazines Reighn first made a blueprint scale model of the room and started working on that. Further he pushed the wall upwards and the floor downwards to look the place spacious. Gary used a high-definition Sony LCD projector with 720p resolution, Polk audio speakers in a 7.1 configuration, a Velodyne subwoofer, Yamaha receiver, Bravo DVD player, Philips Pronto remote, and Bass Shakers underneath the two home theater chairs in the front line. For back row chairs, Gary added few comfy office recliners that cost him $50 each. Gary fitted personal customized cup holders on the back-row seats for resting eatables and other beverages. The equipment s are concerned, they are placed in a rack carved into a side wall that can be used from outside the room. As far as the front Polk speakers are concerned, they are situated into the wall and flank the screen, whereas, the four surrounds are raised to the side and rear walls. Gary built a proscenium, in front of the screen, to place the 12-inch Velodyne sub-woofer and he himself prepared the big 102-inch screen from matte white screen vinyl and steel framing coated with black paint. Gary asserted, The hardest part was settling on the final design and color scheme. I had no idea what I was going to do on the walls. Then I figured I’d put windows in. The acoustic treatments give walls different shapes that also seize attention. Gary says, I knew that if the room were a drywall box, it would sound terrible. It’s definitely quiet when you go in. I used Sound Stop acoustic board, and I needed something that could be cut fairly easily. I think that took out most of the booms, but I’m sure an expert would find frequency response variations. You won’t believe that Gary managed all this in as small budget as about $15,000, which surely is incredible. He said that he certainly could have done better with some added resources. Nevertheless, this certainly is a laudable and praiseworthy work by Gary that brought name and recognition to him. Via: electronichouse
