DIY Video Projector Part II - Page 50

You can get tv tuner cards for notebooks. But what is the point most notebooks don't have enough power to run any cool program like dscaler. Plus as far as a computer goes they aren't very powerful. Also ribbon cables are a big deal. I've seen usb2 pc cards for like 60$. If you are looking for tuner cards on ebay try typing in pcmcia video.

not to mention radioshack and like places have PCB mount connectors.... you can just mount to a small PCB, and solder on the wires you need. this would be easiest. and, if you needed less than that, you could just break off what you dont need.

what are you using this for btw?

Can somebody please start a thread on using a laptop panel for projection? Because it is clogging up the main thread.

newp, its not a HD cable. I have hundreds of those laying around.
It's the flat wire that connects my LCD panel to the module/driver board. basically less than an inch wide and paper thin.

I need to extend the 5" it comes with to over a foot long.

I found a post (on goodle) of a guy that is looking for the same thing but found one for $57.00. I dont want to spend that much.... no way!

Andy,
You mentioned replacing the bulb in the back of the LCD. Do you know if this is a complicated thing to do? Cause if its not too hard, I may do that.
Also, does you know what kind of bulb is a good one? How much do they cost?

Thanks for your help,
Mitch

i found an assortment of nice ribbon cables in a busted DVD player. was able to use one of them for the same purpose of relocating panel. make friends with an a/v repair tech or something.

mitch,

the bulb is the most discussed problem in this forum. The point is, it has to be very bright (about 5000 to 6000 lumens), but not too hot with a colour temperature of 6000 K and has a longlife (more than 2000h). There is written something about that in the other posts before. Some people found some good lamps... I haven't yet... there is more in that old forum "DIY Video Projector Part one"; there you can find problems with lamps people had...
May be you find an idea there.

DIY Video Projector

And taking the lcd monitor apart IS a hard thing (or i am just too dumb

, because i already crushed one...), that's why i am not able to say if it works; i'm still searching for a new(used) LCD Monitor...

Hey all

Just to be sure, but the lens used in an overhead projector is a plano convex lens right?

I'm thinking of just buying it and buying a light and building my own box like a bunch of others here.

thanks

Edit:

I just checked out surplusshed and found a bunch of diff types of lens.... what would be the ideal spec i'm looking for?

for all i know, i'd get this one since it's got a large Diameter...

PLANO CONVEX LENSES
Item No.: L1523
Dia.(mm) 44.00 - F.L. (mm) 400 - At least 25 available.
Price: $4.00 or 10 for $30.00

hehe
