its not hard to notice that box in the celing.. (sp) good job anyways... maybe 1 day you will be able to make it the size of a normal projector...
well, this huge size is mainly caused by the size of the LCD panel.. mine is 13,3" and i got it for free, so i didn't think about buying a smaller one... and the quality of smaller LCDs never reach the quality of big ones...
The other plus is that, with a large LCD, you are not blowing the image up as much as with a tiny lcd - so, less pixelation!!
Excellent work! I have tried to interface to LCD's in the past, and it ain't easy to say the least. Props on finding the correct interface board for the sucker, and its good to see you were able to get it working without mangling up the soldering job. Although it won't have as vibrant colors as say, a huge plasma screen, for the price you paid I'll take that any day. It still looks sweet, and it is huge, so you can't complain for a cheap, working, good projection monitor. The only thing I didn't see in my brief lookings over your post is, do you have fans mounted in the box? If so, are they loud? I wouldn't want to see you melt the LCD panel. Otherwise, great job!
Exelent solder work. I would have given up when that plug thingy got in the way. Is heat a problem? Also I notice that the lense is fixed. any plans to make it slide a bit so you can focus the image?. Oh and what are the overall dimensions of that box? it looks BIG and heavy but those seem to be cuphooks its hanging from Ducati's and Beemers, you know good motors too
That's some amazing work there - well done!! I shall have to try this when I've moved into my new flat
WHERE did you get that reflector!!!! I am currently working on my 17" lcd projector and need a good reflector like that! The only reflectors that I could get my hands on were these small crappers that have a focal of 30mm and diameter of 40mm, way too small of field of reflection to cover the lcd, let alone using a condenser lens! I like how you mounted the lens and condenser, nice simple way to do it. BTW: what focal length is that condenser? and DANGIT you got the project log out before me! I'm still waiting on my order from diyprojectorcompany But good joy anyways! Get that sucker painted!
There would be no difference in the pixelation as you are doing an optical resize rather than an digital resize. The only difference between a large and small LCD is the resolution.
Nope. The projectors we sell (and I sell just about every brand) have .79" (or there-abouts) LCD panels in them. Those .79" panels are 1024x768 native. So, the resolution is the same. This is part of the reason why "real" projectors are so expensive, those tiny screens - running native xga. Now, I have used both a 3500-Lumen $10,000 projector and a 2,500 Lumen $4,000 projector in my home (and I brought to a lanparty). When we pushed the projectors to a screen size larger than they support - we started to notice a drop in quality. Now, with such large panels, you'll be able to throw a larger image before this loss becomes apparent.
Wow, nice. And cheap, cause you pay yourself sick of the good projecors, but one question. Does it warm up alot?
The temperature is no problem. I have 3 papst fans inside; 1x 120mm and 2x 80mm. They all run at 7-8V, so they are very silent. The 120mm and one 80mm fans are mounted in the "light-box", one sucks cool air inside and the otherone blows it out again. That is neccesary because the bulb gets incredible hot. (In an early testrun with the bulb on my table, the table nearly caught fire ). The second 80mm fan is mounted above the panel to keep it cool, because the panel heats up due to the IR and UV emissions of the light-bulb. The whole projector is very silent, and while watching TV or playing videogames you can't hear it at all. The overall dimensions are about 80cm*36cm*36cm. I have no idea about the weight, but it's quite heavy... maybe the wood for the case was choosen a bit to thick. and @thecrownles i used this reflector Diameter 64mm If you need one, send me a PM and i will give you the adress of the shop. ciao Basti
Hi! Nice DIY projector you've got there! Makes me think again of building one myselft If any of you people read french (or if you're curious enough), i suggest you pay a visit to this website: http://www.allinbox.com/ It hosts pictures of nice DIY video projector projects like this one, plus some useful info and tips on how to do it (it's all in french but you can try to google-translate it). Some of those projects are genuinely impressive as regards size, final result and overall craftsmanship, like this one: http://allinbox.com/t1000/t1000.htm
this is an excellent guide, but could you give us some more info about where you bought the optical components (condenser and objective lenses, fresnels, and the reflector)? Cheers!
Basti If that store had a website, it would be nice, as I don't exactly live in germany Perhaps we would be able to arrange a overseas shipping of one of those wonderful reflectors, but if not, then no matter.
