| FRESNEL LENS BOX |
|
![]() Now what could this simple piece of science do for us gamers, you ask? Well, in a word, immersion. Immersion is something that we all look for when playing a video game, and with today's large monitors, 3D accelerators and 3D sound, we have been doing everything that we possibly can, to get every last ounce of immersion out of our systems. We spend hundreds of dollars for the latest video cards and possibly thousands of dollars for the largest monitor that we can afford.
A FRESNEL LENS BOX is a simple and inexpensive device that you can build yourself. It is simply a cardboard box that surrounds your monitor and holds a Fresnel lens in place suspended about six inches in front of your monitor. You can find these lenses in your local book store under the name 'Full page magnifier'. Don't ask for a Fresnel lens, you may get a strange look from the flunky behind the counter. Other good sources for higher quality Fresnel lenses are science catalogs and places that sell replacement parts for overhead projectors. I built my Fresnel lens box a few months ago and I have to tell you, there is no going back! It makes my 17" monitor look like a 30" monitor and I have the sore neck and bad posture to prove it! How do you make one you ask, well its simple, follow these instructions and you'll be on your way to gaming bliss. Materials needed: cardboard, Fresnel lens, black paint, cutting blade, tape or glue. 1.) Get yourself about one square yard of cardboard. 2.) Get a Fresnel lens, I don't care how you get it, that's your business. 3.) Use the diagrams below to make the necessary cuts and folds to the box. 4.) Paint the box flat black to cut down on any glare from the screen and surrounding light sources. 5.) Mount your Fresnel inside of your box using anything you can find that will hold it in place. I used cardboard and glue to make corner mounts that firmly hold my lens into place. The mounting really depends on the lens that you have. Some lenses are flimsy and could be held with tape, others are thick and heavy, so you will need to make some kind of mounts out of cardboard or double sided tape. 6.) Mount the Fresnel Lens Box on the front of your monitor so that the lens is positioned about 6 inches in front of your screen. Use whatever resources that you have to insure that your screen and lens are situated in such a way as to allow you to look through the lens and see your entire screen. You will notice that you will be placing your face really close to the lens and you may actually have to move your head to look up and down at the four corners of the screen. Note: for best results you should turn off the lights to cut down on any external glare that may reflect off of the lens surface. If you can't see your keyboard, you can cut an opening on the bottom of your lens box to allow the light from your monitor to illuminate your keyboard. These instructions should get you on your way to having the coolest 3D enhancement since 3D glasses and if you really want to go for that total immersion experience, you could integrate this into a virtual cockpit surrounding you with controls, padding, sounds and cool lighted gizmos, but hey, that's another article. Warning: some users of this device complain of dizziness and headache so use this at your own risk. In other words, if normal 3D games make you sick, then you better stay back on the porch with the puppies playing pong. ![]()
![]() WARNING: Once you start using this you will never be able to go back to your booring 2D flat monitor again! Note: Create the cardboard box and hooks so that the lens is at least 4" or 6" from the monitor. ![]() ![]() ![]() |
