Well for some of the more hard-core experimentors here, here's an obscurely listed find I was blessed to run across on The Electronics Goldmine. It's listed as:
MEMS Assembly - G13751
MEMS (micro electro mechanical systems) assembly made for a blinding output video projection unit. Consists of a 1" L x .78" W reflective mirror assembly which contains over a million micro mirrors. Each mirror represents one pixel. When a mirror receives a signal it moves slightly, directing the light striking it to hit a lens. A typical projector uses 3 of these units (RGB). The mirror assembly is mounted on a 5" L flat flex cable which terminates in a 100 pin female connector mounted on top of the flex cable. These assemblies may have slight scratches and or slight problems as listed on some of them by the QC Dept. We have no info on these and no way of testing them so we are selling them "AS IS" no returns. The original cost was hundreds of dollars each. G13751
Manufactured by - No Info Available
Price: $5.00
A.K.A. the core component of a DLP projector. Here's the nested link:

If I had extra cash/time, I would totally buy these, but I look forward to seeing what anyone could do with these. Anyone have a guess as to what kind of controller you would need to use these?
Keep imagining!

Holy crap, 5$!? I kinda wanna buy one just because its so cheap. It would be cool to construct a dlp from scratch, someone needs to find out whats needed to control em.
Yeah seriously! For $5, you'd think you could rig up a PIC microcontroller or something to control the DLP. I mean, even if you do your own custom scanning pattern/frequency, it could still be really cool. 🙂 It looks like a pretty basic address-type-interface into the MEMS thing... I'm really really tempted to try it. Buy 5 or 6 of them just in case some of them are broken, maybe I'd get 3 decent ones.

Hey, your back! I've always wanted to do a dlp project... I think thats a little too advanced for me though... I think it would still be awsome to look at one of those in a microscope... 🙂
Yeah, writing your name on the wall with a jerry-built dlp controller would be cool.
My question is why don't they use fast scanning lasers in combination with the dlp chip to scan the image across the screen? Don't have fast enough scanners? Or maybe dlp technology is only at the on-off stage right now.

If you had a fast scanning laser, I don't think you would have a need for DLP? You would just pulse the laser for each pixel. This has been researched before ad nauseum, search for lasers in past posts. Some cool results were achieved -- I even bought a nice first-surface rotating motored mirror to try laser scanning stuff. But then I ran out of DIY Video time. 🙂
DLP is really nice because you get 100% transmissivity. That makes them twice as effectively bright as LCD panels (plus amazing contrast ratios).
Keep imagining!

Oh sure, you could do it, but it would be pointless. Why would you want to scan the DLP? If you were going to scan, it would be easier to scan directly onto the screen and use the video signal to pulse the laser. The point of the DLP is so that you don't have to use a scanning source, but can use a continuous light source and reflect individual parts of it.
Yes, you can scan on the DLP. But if you're going to scan anyway, it's way easier to modulate the laser than to control the DLP.

oh my gosh I cant even begin to think of how to get a standalone DLP chip to work in cinergy with the color wheel and the interfaces for the video. Seems like a lost cause to me, though I would like to see what these " tiny mirrors" are all about, I mean when you think about it dosent it just boggle the mind, Someone actually thought this up, Geese even the standard TV still boggles my mind . Or Cd's DVD's or a computer, Im a college educated person( still in college) and things that people make boggle my mind people on a whole amaze me, mabe thats why Im going into med, nawwww Just wanna give the people facelifts and nose jobs LOL
VF,
I personally for a DIY application wouldn't use a color wheel. I would just get 3 DLP mirrors and do it like LCD projectors work -- just converge the three RGB images into the final video. I could conceive of this working DIY style. Tough part is getting video onto the DLP.
