DIY Video Projector Part II

because you need a very fast notebook for viewing dvds; so this is too expensive

with my way you could use a notebook at 300MhZ (which is not enough for viewing dvds) to put the signal from your local dvd-player through...

🙁 but i forgot to mention that u need a notebook that supports USB2; no idea how much THAT costs...

so i think this will just remain an idea...

Yes i'm sure a PCMIA card will come out, however on a 300MHZ computer what good will it do. Sure you will run win 98, albiet barely, and then the pcmcia card will have its own overhead.....it might never be released as PCMIA but as cardbus and stop that dead in its tracks.

I just think that trying to get a 300MHZ laptop to do it wont cut muster cheaply

laptops are a great idea, but have downsides...

they arent cheap by any means. and to use it for projection, it will need to be dismantled, so its not like you could really use it as a regular computer all that often.

secondly, the screens are fairly large nowadays. and if they are smaller, they are not TFT, or not high res. so the screens that would work for projectors are going to be a little too large.

next, if you are going through ALL this trouble, why not just spend $400 and get a lcd monitor for your computer? you can then get a $30 tv tuner card for your desktop, and all is good. you dont have to shell out for a laptop, and god knows that once the USB2 tv tuners come out, they wont be cheap. plus, most people thought of using older laptops, but, older laptops wont have usb2...

so, the laptop isnt really that great of a solution (not to mention those screens dont really "come apart" too easy to fit into a case for a projector". its too much money, when you could just get a cheaper lcd flat panel monitor, and you are at the same point with the laptop for 1/3 the cost, and none of the hassles.

uh, if im not mistaken, isnt that an IDE HD cable? if so, they are easy to get. can go on pricewatch.com, and look for IDE cables, OR, just goto best buy or compusa. will be like $2. HD cables might be 80 pin, but whatever, chop one in half 🙂

yep HD cables...the older ones are 40 pin, make sure you dont get one of those new ata 66 or ata 100 cables because those are the 80 pin suckers.......but the older 40 pin cables should be cheaper and thicker wires....if you need thin wires you could always go with the 80 wire one and cut it in half or use every other connection.......that will be a PITA to solder though.

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.

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

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.

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 🙂

Hey everyone, reading all this is really intriguing. I REALLY want to make one of these babies as I do not care to spend 3K+ on a TV.....

I just wanted to say Hi, and also is this site "http://www.diyprojectors.com" going to come up soon?
