100'' PROJECTION TV PLANS PURCHASE THE FOLLOWING ITEMS: 1. Rectangular magnifying lens (at least 3" X 5" for best results) The best size for this plan is 7x10 2. Duct tape (2 inches wide or more) and BLACK electrical tape 3. Black presentation board (Poster board) Cardboard Any office supply store would carry this item. Make sure it has a length of at least 28" and it is the thick poster board, not the thin flimsy stuff. Cardboard is best and the inside must be black. 4. Pencil or marker 5. Razor blade or box cutter (scissors can be used, but razor blades are much easier) 6. Mirror (at least one inch larger than the TV screen) The best place to find the mirror size you need is at a home supply store like The Home Depot or Menards. If you need assistance finding one ask for a "Beveled wall mirror without a frame" in the size you are looking for. They are the lowest cost mirrors you will find. I got one for $14. 7. String or wire about 3 to 5 feet long. 8. Ceiling hooks (2) 9. Door Hinges (2) - OPTIONAL 10. Black Flat Spray paint- For the inside of the box that goes around your screen. ASSEMBLE THE PROJECTOR 1st: Measure the vertical and horizontal distance of the television screen. DO NOT measure the entire TV, the projector attaches to the screen. 2nd: Cut your projector's frame pieces. Use the entire length of the poster board (usually 28") and the width should be the measurement of your screen. For instance if your screen measures 8 x 11, then you will cut two pieces to measure 8 x 28, and two pieces to measure 11 x 28. IMPORTANT: Make sure that your cuts are straight. 3rd: Cut your slider. This is the piece that will be used to focus your projector. Getting the proper focus could take a few minutes. Cut this piece using the measurements of the sides widths. In the example an 8 x 11 screen was used, so this slider should measure 8 x 11. 4th: Take the Magnifying lens and place it directly in the center of the slider. Trace around the lens and carefully cut out the rectangle. Make the cut just a bit to the inside of the line. You may use black electrical tape to hold the lens in place, just be sure to cover as little of the lens as possible and be consistent on all sides so you have straight and even lines. You MUST cover the clear border around the lens itself, failure to do so will affect the quality of the picture. Hint: to find the center, draw two straight lines diagonally on the slider. The center will be where they intersect. 5th: Tape the sides and top and bottom together, tape to make sure no light shines through. If the poster board is not black on both sides, the INSIDE must be BLACK. At this point you should have a box with four sides. IMPORTANT: The inside of the box should be the exact measurement of the TV screen. 6th: Insert the slider about halfway into the box. The slider should fit snug and should not allow any light to pass through the edges. Light should only pass through the lens. If there are small gaps of light, don't worry we will fix that in step 8. As long as the slider fits snug you will be okay. 7th: Size the projection screen. Turn off all lights and block as much light as possible from the room. The projector works best in the darkest room. Turn on your TV and adjust the contrast, brightness, and color to the highest setting. Hold the projector to the screen of your TV. You should see light projected on the wall. If you want the screen to be larger, move the projector away from the wall. If you want the screen smaller, move the projector closer to the wall. When you get the size you want, measure the distance from the end of the projector to the wall. This is the distance you will place your mirror from the wall in step 10. NOTE: You can use a projection screen, but a plain white wall works just fine. 8th: Focus the projector. This step may take a few minutes. Adjust the slider in and out until the picture is focused. The picture will be upside-down, don't worry about this now, just get the projector in focus. You will flip the image in step 10. Once the image is in focus, use the black electrical tape to hold the slider in place. If there is any light passing through the box from anyplace other than the lens, then make sure you block it with the tape. 9th: Unplug your TV and turn it on its back so the screen is facing up. The bottom of the TV set should be facing the wall that you want to see the picture on. Attach the projector to the TV using tape or whatever you want to use. No light should pass through the edges. Light should only pass through the lens. 10th: Attach mirror. The dimensions of your mirror must be at least one inch larger than your TV screen. For example, if your TV screen is 8x11 inches, then you need a mirror that is at least 9x12 inches. The mirror can be larger, but not smaller. Usually the mirror will come in a cardboard box with the face of the mirror showing. Do not remove the box. If your mirror is not packaged this way, you need to make a frame out of cardboard for your mirror. Now take the Duct tape and cut about 6 pieces each 8" long. Place 4" of the tape on the projector's outside that would be opposite of the wall where the screen will be (this should be the TOP of the TV). Place the remaining 4" on the front side of the cardboard holding the mirror and at the bottom (horizontally). With the duct tape wrap around the projector about 4 times at the top. You should now have a mirror that is attached to the projector and be able to move it up and down. Use your own judgment and creativity to make sure the attachment is strong enough. Place the ceiling hooks in the ceiling about 18 inches behind the projector and one in front of the other (about 6 inches apart). These measurements do not have to be perfect. At the top of the mirror (horizontally) you need to cut a small square in the center of the cardboard. If the box has a handle at the top, just use that. Now make 2 small cuts in the bottom two corners of the cardboard holding the mirror. With string or wire tie a knot in each corner and run the string up to the back of the 2 ceiling hooks. Make the string tight so it supports the backside of the mirror. With a second piece of string or wire tie a knot to the top center of the cardboard and lift the mirror to a 45 degree angle, then tie the other end to the front of the 2 ceiling hooks. Note: in place of the duct tape you could buy a couple of hinges for a door or kitchen cupboard to attach the mirror. Another Option- If you'd like to have the best picture possible you can go without using the mirror and either you or a tech can switch the vertical and horizontal connections to your TV tube. One set is green and blue-the other is red and yellow (I would DEFINATELY have an experienced tech do this. He/She shouldn't charge anymore than 25 dollars to do this. Call around to your local repair shops and let them know what you want done (switching the horizontal and vertical connections on your TV) to find the best price. Finally. With the room as dark as possible, turn on the TV. If the picture is too high or low just adjust the angle of the mirror. Make sure the color, brightness, and contrast are at the highest settings. Also, the projector will need some cosmetic help. Decorate it to your own taste. Enjoy Your Big Screen TV Projector!
