Nah, search 'projector panel' on ebay. I ordered an NView one. Just stick it over an old overhead bought from a school, and you've got a 50" projector. A lot of projector panels can be had for $20-$30, and a lot of them come with composite, S-video, and VGA, not to mention some have remote controls.

so if you buy a projector panel and a school overhead projector and you attach the panel to the overhead you can play video games on them right??

If the projector panel has composite in, then yeah.

@Harshboy, So is 15 in. the biggest you can go with the LCD and still have it display everything on the projector? I want to do this, so I'm trying to figure out what it with cost for the screen.

Harshboy · Post by **Harshboy** » Tue Jun 13, 2006 10:29 am

Yes. You can probally get a nice 15 in. LCD for 100-150 tops. I think i might finally be able to do this since my dads old compy died and there was a nice 15 in. LCD being used on it

Just need to buy a projector from my skool.......or eBay, either one

EDIT: This is what i'm using as my LCD

There was a thread about this topic about 6 months ago, and it inspired me to build a DIY projector of my own.

I guess this is a good time to show a few pics of it:

Unfortunately, I can't set it up at home right now to get a pic of it running (I used it for our TV in the college dorm, but I've moved home now for the summer), My parents will kill me for making a mess in the living room.

Here's a pic of the Metal Halide bulb with the ballast and other circuitry, which normally sits under a mirror. The mirror is removed for the picture:

I will try to get more pics if this thread gets any more in depth, but for now, these should be fine.

All hail SNESguy's magic pyramid.

That looks pretty cool. If I make one, I'll just be lazy and use an overhead. Does anyone know if any LCD will work? And Harshboy, If you can get an overhead from your school for $50, its a pretty good deal because all the ones on ebay cost a lot for shipping.

Yah, I started that thread after I found Lumenlab and bout my projector. I now have a lovely XGA (1024x768) projector that I can do anything with basicly. The thing cost me $300 CDN, mostly because I had to buy a $150 LCD. I plan on getting at 17" Widescreen TV eventually so I can make a HD projector. Hmmm $800 for a homemade HD projector or $3000 for a commecial one... tough desision.

Plus the most important part... it's really freaking fun! I had a blast making it and enjoy it every day.

With the whole "LCD panel on an old school projector" dealie, can you do that to say... game boy and GBA screens?

I bet you could do it with a psone screen but it would look like crap when it is 100" of pixelation on your wall
