Does anyone know where the hell I can get cheap bulbs for projectors???

Its nice having a projector but price for keeping them running is just silly???

Faidzir, Search under DMDs. You'll never find anything under DLPs. I found one place here in the US that had several parts for DLP, including wheels.

Good Luck!

Guys and of course Guyettes.

1/ Don't dismiss my post until the you reach the end.

2/ I am a newbie at electonics. but read (1)

3/ I have been following this post for the last couple of
weeks , and the good thing is that I have registered
to DIYAUDIO.COM to submit my idea.

Has anyone considered how a telescope works. ( ie moon
telescopes )

Is there an opportunity to use such a device in this
projector

ie
Big light source at one end of the projector( the moon - the big end of the telescoope) , bouncing light off 2 mirrors to a small lens ( the eyepiece part of the telescope )

This should get rid of the heat problem, especially if the walls for the telescope was reflective. And provide a big light source to the screen matrix.

If I am being stupid in my thinking, then my apologies, but to me if the light source is big and bright enough, it might work.

My $0.02 worth

regards

Gaspode, I was thinking the same thing,only with camera lenses. although I do have an old telescope that I was thinking about playin around with.Anyone else think it may work??

I'm interested in getting or building a video projector. I have a very low budget so unless I were to get something real cheap it looks like the DIY route is the way to go. I'm nearly complete with my MAME arcade cab so I'm familiar with doing these kinds of things.

Last night I sat down and started searching across the search engines. I came across this page and actually read every post from beginning to end. I'm thrilled at the interest in doing this.

A couple people mentioned it but I don't think anyone really gave any concrete results for it: What about putting a lcd screen on an overhead projector? This seems so simple compared to the other routes people are taking. Am I missing something? This seems so simple to do. To reduce ambient light you could block off the area around the lcd panel so that light only comes through the lcd. You could also build a sort of box that would enclose it. Comments? Keep up the good work.

Seems like one of these lcd projection panels on an overhead projector would be a perfect solution. could easily be done for under $200, too.

The problem might be this

The result sucks for movie but it is still good for presentation

BTW, bulbs selling on this site are not expensive at all
http://www.carparts.com/parts/newsea...-0-0-0#product

or try the PIAA ultra white lights
http://www.carparts.com/parts/newsea...-0-0-0#product

I wonder if those light are good enough for the cheap LCD projector panels.

Agent Davis · 28th November 2001, 06:33 AM

Are you saying the results are bad because of the yellowish tint? If so, I'm sure this can be remedied by using a brighter, whiter bulb inside. Something could be rigged up fairly easily it would seem. If the actual OHP bulb couldn't be replaced by a whiter, brighter one then one could probably still jimmy rig up a light inside using something like a very bright white headlight. The lenses and everything else would still be the same, just change the light source inside. What do you think?

It seems these overhead projection LCD's are very cheap... I mean it looks as though some are going for $50 or less. It looks like there's some good OHP's for about $50 too. Add the cost of replacing the bulb and rigging up something real bright and you easily have a sub $150 project. I'm starting to get pretty excited about the idea of watching dvd's and playing games on a huge *** screen. Darkening the room wouldn't be a problem at all here.
