BYO LCD Projector

NiN^_^NiN · 03-21-2005, 06:47 AM

Well i just got a overhead projector off ebay which runs $5 bulbs that last for 200hours

I just took apart a 7.6" lcd (it's a OEM lcd so thats why it's a wierd size) and placed it on the overhead projector and i quickly blacked out the sides where the light was escaping and GOD DAMN it looks gooooooooood

It's crystal clear and it's pretty big

not bad for a LCD projector thats cost me $230 all up

I do have a few things to fix up and i'm gonna see if i can get a 10" LCD for use with it so it's a even bigger picture

Just wanted to rant about what i made :P

i'll put up some pics in a few days but i need to build a stand for the LCD and a fan to keep the LCD cool while above the overhead projector.

The quality is just so damn good i really am shocked i expected it to be a ok quality worth watching movies your already seen.

Sorry for the smiley overload

Yea, I want to give this a try myself, I just have too many unfinished projects going on. So, the LCD project will have to wait for now. I'm glad to know that yours works well though

Lumenlab is a great place for stuff like this, the forums are awesome.

As is DIYAudio.

Here is my home made OHP - I still used the ARM from a OHP

migel628 · 03-21-2005, 10:07 PM

Kind of looks like Johnny-5 from Short Circuit

Here is another view
I went to DIY Projector Company
and got this guys free plans - I used the MkIII plans - I removed
the top, I just cut above 3 inches above the LCD tray - to leave a
way to keep the LCD in place

Works great -

Didn't Toms Hardware guide have something on building projectors or is that what you guys are building from?

will1384 · 03-21-2005, 10:48 PM

Yep Lumenlab is the best
to start with - it does cost $20 to get into but well worth it

My next projector may be a lumenlab style

You may want to upgrade to a HQI setup its about $100 but even with a 250w setup you can watch TV with the lights on and the $30 lamps last 20,000 hours -

I used one of them OHP LCD pannels - I am lazy - got it for $50 on ebay
just before the Toms Hardware craze drove prices up

I felt the same way, I was the happiest man on earth - like I just got married
to a super model - A big TV does that to a man

Good luck, and keep us posted. and put up some pics -

I built one from an Apollo A1000 and nView Spectra C (total project cost of <$100) a couple years ago. The display was satisfying but the unit itself was way too big and noisy so I got rid of it.

Sorry i took so long was waiting till good friday to spend some time on it

I got it hooked up in the lounge room and the quality is ok but in my room it's fantastic and i noticed why

I've got digital tv in my room and it's crystal clear but on normal cable tv it just looks a tab blury compared to the digital tv.

I attached a few photo's i took some from a cartoon and some from a real tv show.

Now in the cartoon you see some lines etc on the picture that is cause the glass top broke when the unit arrived

So i used the glass top off my old table which is very dirty and thats why u got the lines

I also put my hand over the flash a bit so you can see the actual screen and some of the image projected.

It really is great but i reccomend you use something like digital tv or get a xga monitor/use a old laptop with a video in card etc.

Enjoy the pics
