DIY Video Projector Part II

[slize]

may be i got some things wrong; espacially this "lol"
(what means "laughing out loud")

and you said that several times, so i felt attacked...

i am in this forum since the first post of the first thread when
vince aka vdi_nenna posted his ideas of LEDs with panels...

Since then i have read EVERY single post, so don't tell me to read this forum...

yeah sony and so on are using small panels and small bulbs to make their projectors portable; which has nothing to do with the light out-come (it complicates a good projected picture because of the optics but thats another theme) mainly the bright light comes from the special bulbs they have (that's the reason it costs 100 of dollars to replace them). they have bulbs at 250watts but with 100000 of lumens...

but my projector doesn't have to wheigh 6 pounds it can also weigh 60 pounds if only the quality of the picture is good...

go and read some pyhsics books about lumen, lux etc. and you will see that my theory is correct...

hi rapsac,

the panel has TCO 99. i think at this time all response times where at about 35 ms (i hope so... ) i'll see when i have it. but on my first projector i had a MaxData PC Monitor TFT a it came with TCO95 and worked well too... then i got a MaxData TFT with TCO99 and it worked great (this is what i use now)...

the point with the panel is too bis for a fresnel is solved through an fresnel from an overhead projector, which is big enoug to light the whole 15" panel.

That's the main reason why i bought a 15" TFT with sxga. I can be sure the fresnel will light up the whole thing.

best regards

my bulb is an OSRAM Powerstar HQI-TS 400W/D with 45000 lumens and 9000h life time. actually it is an HQI bulb which is mainly egual to MH bulbs...

oh dont u worry slize ive done my theory ive done my physics and reading on light, maybe u ought to read up on what u can do and how to control light, and the main reason sony and the other pro's make projectors so small is not only because of them being portable but also no one wants a 60pound box in the middle of their room not to metion a 400w current draw, if u did some research on projector bulbs they are not so special eh? its the size of the bulb that matters to them and the output, and buy the way a typical 250w projector bulb puts out a max of 20000lm's, and they only add a small amount of mercury to the gas to get it that bit brighter thus costing them life and also over current, the main reason u pay a high amount for the projector light is also the reflector, its not just an ordinary reflector no more, its a work of art and a filter, so why dont u read up and email around and maybe u might learn somthing for yourself instead of just by whats going on in here and have some respect while your at it, oh and dont u worry about respecting me slize im leaving this video forum as far as im concerned if people dont want to listen, beleive in things that have been practised not just in theory but practically aswell well im out, im done with helping jelous ****heads like yourself who instead learn' pic and acuse me of being a know all, sorry but any info is good info when u are learning and if u cant hack that good bye, another thing i have never posted somthing i have never tried or hasnt worked, the only thing i posted that i didnt try was about ohp"s and condensers, cruser did that at the exspence of my help wich he is greatfull for and he conducted the experiment i told him, it helped me and it helped him, i beleive that is called coperation and helping the other out somthing u have yet to learn, and i dont care how long u have been in here for it doesnt make u right! eh?

anyway im gone with the rest of the pro's who knows whats best see ya all

[prjctr_builder]

you are a noobling who doesn't know S*&T and trys to convine us all of your ingenuity. I am sorry, but ACE knows 10000 times more than you... and because of sorry noobs like you, pros leave this forum and it makes others quit building their prjectors. If anyone had to go from this forum, ACE would be the last one on the list....

Hey Ace we're gonna miss ya buddy

I bet property is behind this all lol

well im leaving too (if anyone cares...lol)
im kinda bored with DIy.. plus my ISP is going off soon..

WE SALUTE YOU ACE!!

save me a kangaroo ol' bloke ...hehehe I'll c ya on yahoo


C U NEXT TUESDAY BUDDY!

[slize]

i am sorry to see you leave... honestly ...never meant to hurt your feelins bro'...

too bad i cannot profite from your help anymore...

i never doubted your thoughts but HOW the **** can get an sxga projector if not using an 15,4" TFT??? isn't that the best way yet??? any ideas ace???

[slize]

what the **** is wrong with you??? i am NOT telling everyone MY idea is the best way and everyone has to follow me... i am NOT even saying my projector is better than ace's... the opposite is the case, i think ace's projector is great; because of the design and the wheigt. it's the best projector this forum has brought out... all i am saying is I want a projector with sxga resolution, in my case for the price of design and wheigt... i wish i could built a projector like ace's with an sxga resolution, but i didn't get any help for this, all i got was critc "how dumd i am to use a 15" tftf"... thanks ace... but i don't know 5,6" tft panels with sxga...

i never told ace he should **** the **** off, the was his own decision; i think he likes bitching around a bit...

i am just presenting my idea and were attacked for that even from you; we can compare result sas soon as i am finished if you like to, but you won't see any differences... know you are asking me "why do you build a projector with sxga then, if there are no differences?" my answer is: "for me!" so that i can say i have built an sxga projector; u got that?

my appologizes go out to ace, because of my bad english understandings...

[slize]

i am working right now on a light unit with a big reflector and my aim is to run it withou a fan and not to come over 45°C... i thought to use mirrors, will that help? what do you think?

[lincoln]

hey there. what type of projectors are you guys using?

i have an old slide projector, it works quite well. i was wondering if i could do something similar with it?

it dosnt have a round thing with the slides.. it has a thing that you push in to use only 1 slide.. loading manually.

if i could do this, would i need like a 1" lcd to put where the slide goes? or could i somehow make it so i can use a 5" or larger lcd?

thanks.
