Getting startedWhat you need is: A fresnel lens, some cardboard (or thin, light wood) and a monitor of course. The plan is to build a box on the monitor on which we mount the fresnel lens. Step 1 - Start by cutting 2 trapezoid pieces of cardboard with on one side the same width as you monitor and on the other side the same width as your fresnel lens. The distance between those 2 sides is your "o" in the magnification-formula; you can choose this by holding the lens in front of the monitor and measure the distance between the lens and monitor when you get a large and sharp image; if the image is too small, try holding the lens further away form the monitor; if the image gets too blurry, try decreasing the distance between lens and monitor.  Repeat the same for the height of the monitor and lens. You now should have 4 pieces of cardboard consisting of 2 pares of identical pieces. Step 2 - Paint the inner side of the cardboard black (use flat or matt paint for best result). Step 3 - Glue the pieces of cardboard together to create a shape that looks like a pyramid that's missing the top. (you can also use tape)
 Step 4 - Glue the fresnel lens in the cardboard construction (be careful not to spill too much glue on the lens itself)
 Step 5 - Now mount the construction to your monitor (it's best to use strong tape instead of glue if you don't want to ruin your monitor)  If you now look through the fresnel lens, you will see a big image where the 3D 'pops' out. It's amazingly realistic when playing computer games or when watching your favorite movie. *Note: pictures of my monitor with lens and actual pictures of the building process will be coming as soon as I get my hands on a digital camera. You can always send in your own pictures and I will put them on this site. |
