The Digital Projector Project
( www.particlefield.com )

These are the pics of my homemade digital projector and the results so far. The LCD panel I sacrificed was a Viewsonic VG150 and the overhead projector was a 3M 9700. The 2 PC fans are connected in parallel to the backlight connection on the LCD's driver board and the LCD is now mounted directly on the fresnel lens to maximize pixel coverage.


The first pic shows the amount of light in the room when I started taking pics and the second the amount when I stopped (window blinds would have been really nice because it was obviously a little bright in the room).


These pics are mainly of the LCD panel and it's frame. This was the most expensive part, coming to about $300 for materials and the LCD monitor itself. Construction went smoothly but I was pretty lucky. Mounting the LCD panel once it was out of the monitor was fairly scary because the main ribbon cables seem very fragile, not to mention the glass panel itself.


Here are a few shots of desktops, movies and other random things on the projector.


I had to try out Visual Studio...


As far as gaming goes, I think my addiction was bad enough before I built this. The shots are a bit blurry but you can't pause the game (Freelancer) without the menu popping up. I am really impressed with gaming though on this. I plan to install a TV card within the next week so hopefully by the time the fall semester begins I'll have the setup perfected for the PS2, cable tv, movie server, and music vizualization plugin.


Well, that's pretty much everything. The whole project ended up costing around $500. If you're looking to do this yourself I'd recommend using ebay for everything, as the LCD monitors can be found used for a lot less, and projectors can actually be found at reasonable prices. One other thing I'd highly recommend is to use something other than a wrinkled bed sheet for your screen :P
