[Trout]

free 100" tv plans!! Link To Drawing

I havent acually tried this yet. I just saw the plans on a link off fat wallet,So i dont really know if it works good. You can check on eBay where these plans are selling for $15-20.


PROJECTION TV PLANS

PURCHASE THE FOLLOWING ITEMS:

1. magnifying glass (at least 2 inches, 5 inches works best)
**note: don't get the magnifying glass that has the magnifying spot on it, you'll know it when you see it** (They are also selling these lenses on eBay for $1.99)

2. Duct tape (black duct tape works best) 2 inches wide or more

3. Cardboard or presentation board (the presentation board used for school projects works best)
**note: you can buy black presentation board, and you may not need the spray paint, I didn't**

4. Flat black spray paint

5. Pencil or marker

6. Exacto razor blade or box cutter (scissors can be used, but razor blades are much easier)

7. Mirror (about 5 inches in diameter)

LET'S ASSEMBLE THE PROJECTOR

First: Measure the vertical and horizontal distance of the television screen. DO NOT measure the entire tv, the projector attaches to the screen.

Second: Cut your pieces. Using 32 inches for the length the width should be the measurement of our screeen. For instance if your screen measures 25 x 24, then you will cut two pieces to measure 25 x 32, and two pieces to measure 24 x 32. Make sure that your cut is straight.

Third: 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 a 25 x 24 screen was used, so this slider should measure 25 x 24.

Fourth: Remove the lens from the magnifying glass and place directly in the center of the slider. Trace around the lens and carefully cut out the circle. The lens should fit in the hole snug.

Fifth: Paint the projector and slider using the black paint, both sides. It may require more than one coat of paint. Do not paint over the lens. Take the lens out for this step.

Sixth: Tape the sides and top and bottom together, tape to make sure no light shines through. At this point you should have a box with four sides.

Seventh: Insert the slider about halfway into the box. The slider should stand up and should not allow any light to pass through the edges. Light should only pass through the lens.

Eigth: Unplug your tv and turn it upside down, attach projector to tv using tape or whatever you want to use. No light should pass through the edges. Light should only pass through the lens.

Ninth: Turn on your tv. The room should be as dark as possible. Adjust the slider in and out until the picture is focused (this will take a few minutes). Remember, the farther the projector is from the wall, the bigger the picture will be.

Finally: If your projected image is reverse place the mirror at a 45 degree angle in front of the lens. This will also allow you to adjust the height of the picture. After the projector is focused cut the excess of the projector in front of the slider off.

Saw This On Fat wallet,, thought it was cute

It should work... but note the guy is talking to the lowest common denominator....

I wonder if he had complaints about his previous set of instructions

This setups market is the lowest common denominator. These setups tend to be very dim and fuzzy. Really only worth trying as a novelty. There just isn't enough light coming from the TV for this to work well.

Be simpler just to make a pair of binoculars

Yes, this idea has been around for a long time.

If you take their suggestion of a 100" image, and project it from a 25" TV, the area the image covers is 16 times as large. Even if the transmission process could be nearly loss free, the projected image will have at most 5% of the brightness of the TV image...

i used to have a very old projection TV system that worked the same way. It was a wooden cabinet with a 45", highly reflective screen on the top. it has a box below the screen that folded up. when you pulled it down, there was a mirror on the one part and then a large 7" magnifying lense. and a small 13" TV with the picture tube installed upside down. it worked ok, but it had to be very dark in the room and you had to be directly in front of it, or it was too dark to see.



if you really want a giant tv, get yourslef a dlp projector. i have an infocus x1 and i aboslutly love it.

I just use my Dukane projector, it works MUCH better.
