Repairing a Projector with Tinted and Washed-Out Display

My employer came to me with a little project. The office projector stopped working properly after someone touched the pins of the VGA video cable, and presumably released ESD energy into the projector. The picture’s colours were all tinted and washed out!


Note that the bottom monitor is displaying the same colour pattern
as the projector. Grey is completely missing!

He asked me if I’d like to take a look at it. My answer, as would be expected, was “of course!”

Video Blog – Laser Projectors

We upgraded the arcade again, this time adding some awesome, hypnotizing laser projectors! One displays a constant pattern, the other is reactive to music. We also installed a motorized disco ball, which reflects the lasers around the room!

Halloween =]

Well, this Halloween Matt suggested to me something I could do in the spirit of the occasion: setup a projector that would display creepy video: ghosts, zombies, graveyards, etc. I figured, why the heck not? The projector doesn’t get used nearly enough, so I might as well take it out for a few hours and see what happens. The video below is the result:

Pretty awesome, eh? Scary? Maybe not so much, though one kid was afraid to come up our drive way to get some candy! Not many people came by, we maybe had 8 or 10 groups of people, perhaps a total of 30 individuals. Still plenty of candy left over for me, mwuhuhuhahaha! Too much. It was neat though, how the white sheet made the perfect double sided projector screen. Sure beats paying $100+ for an actual projector screen! And of course, a white wall is still good enough (when immersed in a movie, you don’t notice things like holes and dents).

Oh, check out the Music page above, I added a new song. I’ve been working on it since June 10th, so it’s been a while I’ve been adding to it, but I listened to it again at school today and realized, damn, this is a really good song! So tonight, I added sections, created a nice piano interlude/bridge… I’m excited. In celebration, part of the song is up for you to enjoy! Again, leave me your comments!
