There's no doubt that most people looking at this have come across a
video projector before. Maybe it was at a business meeting, or maybe
it was during a high school or college class. If you're anything like
me, you probably thought of the gaming possibilities of the projector
instead of it being used for boring PowerPoint presentations. I
decided to look further into projectors and found a very interesting
niche in the technology that lets you build (don't get scared! There
are no tools involved!) a quality projector for under $200.
The niche I am referring to is in a technology called Projection
Panels. Before LCD projectors were being manufactured many major
presentation-based companies (3m, dukane, infocus, nView, etc) created
LCD panels to sit on top of a standard overhead projector. Many people
have seen these in math classes used with a teacherís graphic
calculator. This is the same idea, only with higher quality LCDs that
support VGA input.
There are a few main steps that will be discussed in this guide.
- Space Requirements
- Choosing a panel
- Choosing an overhead projector
OK, so you've got the desire and the money to have a
projector. What next? Well, first off you need to make sure you'll
have ample space for it. Keep in mind that you will need a white
wall to project your movies/games/TV/internet surfing onto. If your
walls are painted, covered in wallpaper, or textured, don't fret!
Before we go any further, let me apologize in advance for the low
quality of the pictures. I assure you that they just donít do any
I was lucky enough to have plain white
walls in my room, so creating a screen was not an issue for me.
However, if you need to make one, head down to the local crafts
store and purchase some large sheets of white poster board and make
a screen out of these. At Dollar General these sheets go for 3 for
$1 I believe, so for probably $4 or so (9 sheets plus $1 for scotch
tape of course) you can make an inexpensive screen. If you want this
to look halfway decent with your home decor, projection screens can
be purchased online and at office supply stores. Keep in mind that
screens can be rather expensive.
Once you've verified that you have enough surface area on your wall
that you'll be projecting onto, make sure you have enough distance
away from it to place the projector. Different lenses provide
different ratios of course, but for example my 6' diagonal image
needs about 10-15ft of space away from the wall. The size of the
screen on your panel will also affect the size -to-distance ratio.
