I have been using this DIY projector that I built since 2004. It has been modified as new options and or new technologies become available and it has been amazing for my wife and I. Let me make one thing CLEAR! I am not associated with Lumen lab monetarily but I have been a very happy member for MANY years. I'm not promoting but sharing my happiness with the end product. Enjoy! I hope! :thumbup:

This is the basic kit with a 1:1 ratio for throw (distance) vs width of the projection. This is 7 ft away from the screen for a 7ft wife projection. 8ft away would produce an 8ft wide screen.

This is a comparison of the movie "Collateral damage" Showing the laptop screen (running the projection) and the 7ft wide actual projection.

I built a proper projector stand for the projector that housed the computer that runs the projector. It was made from oak (mainly), poplar and the top is maple (I believe) pallet wood that is usually thrown away.

This is the second version using an 18" focal length Projection lens from a 1950's and later projector. The one that projects pages from a book placed inside the bottom. My projection distance from the screen to the tip of the projection lens increased from 7ft to 11 ft.

This is the extension on the projector for the increased focal length projection lens. The longer the the distance from the projector to the screen the longer the projectors optics will be and the box.

This is what the new 7ft wide protection looks like with the new optics and the new throw distance of 11 ft.

This give you an idea of the size of the 18" focal length lens. Larger than a CD.

I have modified it again with a 22" projection lens that gives me another 2 or so feet of projection distance but I haven't taken any pictures.

Here are some pictures of a vertical projector that I built for a friend using he 18" projection lens.

Well......I hope you have enjoyed this information. These projectors are easy to build at a fraction of the cost of a commercial one. I have been using the same bulb for 5+ years now and the replacement cost of a commercial bulb is $300.00 plus! Enjoy!

T73,

I'm just a guy with power tools with a knack for woodworking! These projectors are stupid simple to build and the directions are free and the end result is stunning. I'm looking for the link to the free PDF instructions.... let me find them.

So, if I'm looking at this correctly, it's a simple overhead projector built to project the actual LCD sceen? Snazzy. :cheers;

My wife would dig it!

A lot.

Nice rig! I'll bet it was good fun and kept you off the streets.
Some folks may cringe each time I use the term "Booze" regarding these high quality drinks.
I mean no offense. There are bottles of extraordinary booze out there. I've tasted a few. Relax.
