Postavte si vlastný LCD projektor

[Venton]

Tak jsem zase drobet pokročil se stavbou můžete mrknout:

[Locke]

Jinak resil nekdo reflektor pro lampu z jancy? Pouzivam to "zrcatko" z izzoteku, efekt ma, ale uz jenom z principu je tam velka ztrata svetla (viz fotky). Docela dost se pouzivaji ruzne lestene misy, zkousel nekdo neco takoveho? Dal by se tim desne zvetsit "svetelny vykon".

[kopat]

Ahoj, měl bych nějaký malý dotaz, rád bych si zakoupil nějaké věci v Izzoteku, ale ENG už tam není a nějak mi ušlo jak to zboží vlastně zaplatím - nějak jsem tam nenašel placení kartou (pouze PayPAL).
Můžete mě někdo nakopnout správným směrem - třeba i odkaz do forá (nic jsem k tomuto tématu nenašel), Děkuji

[Locke]

Zajimave:

If you use a real hot light there is another way to keep from melting your fresnal and LCD, here I held up a piece of Low-E glass it is 2 pieces of glass that has argon gas filled between them and it keeps the heat from passing through I will probably use this once I upgrade to a 1000W lamp.


Porad se snazim resit efektivnejsi reflector, podle me mame svetelne ztraty tak 80%


http://www.greenhome.cz/new/clanky/109/


Zaujal me ten reflektor industria s odtahem a rozptylkou. Co jsem tak googlil, da se to koupit treba tady, http://www.growshop.cz/cenik.xls asi se na to pujdu podivat. Dale je velmi cenna (i kdyz logicka) informace, ze sodikove vybojky davaji nejvice svetla po stranach.

Zajimalo by me, jestli se daji nejak spocitat parametry te casti elepsy (tedy paramtery elipsy celkove)+idealni vzdalenost svetelneho zdroje, viz

Pak by bohate stacilo vzit treba i kus staniolu, dat ho na nejaka zebra aby drzel tvar a je to zadarmo a jiste velmi funkcni...

Neví někdo jestli nepůjdou zapojit ventilátory do konektorů pro podsvícení LCDčka u toho Benqa FP567 /nemám měřák/

[hoyo]

Ahoj.Velmi ma potesilo ked som nasiel tuto stranku.O vyrobe projektoru som uz davno snival ale nevedel som ako nato.Nieco sa mi podarilo zohnat ale stojim na LCD.Neviete niekto o PSONE?Nejako sa mi to nedari zohnat.

Heh myslím, že asi nee. Mám (měl jsem ) podobné LCD 15", ale je to LG Flatron a ten napájel studenou katodu poměrně vysokým napětím. Myslím, že je tam něco kolem 500 nebo 600V.
Větráky bych na to určitě nezapojoval.

Kdyby si predtim pouzil google, tak ses to davno docetel
Jinak na psone kasli, s normalnim lcd se v pohode dostanes pod 10k a kvalitativni skok oproti psone je giganticky.

neviete ako to je s benq t502 ci ho tuna neskusal uz niekdo rozkuchat a ci nema ffc problem?nikde som nic o nom nenasiel. vyzera ze sa predava len v australii a u nas
lebo nic ineho teraz na skladoch v SR akoby nebolo, vsetky 15ky velmi rychlo miznu zo skladov nikdo neobjednava kvoli 17kam uz 15ky.
som zavahal a teraz 567ka je vyradena uz aj z cenniku napr v ageme.
popripade ak by ste vedeli niekde v SR kde maju momentalne vhodnu 15ku bez ffc problemu.

- Lilliput 7" SVGA 2400x480 dots widescreen panel (Ebay).

These things go for about $200 and are great for people who need a smaller projector. The resolution isn't as high as a 15" panel but it's perfectly acceptable for medium sized screens up to 8' diagonal. I'd imagine 6' screen size is optimal for these. There is no FFC issue but there is a small circuit board that must be bent 90 degrees from the panel; doing this requires no skill however, just move it out of the way. Make sure to get the SVGA panel, 2400x480 dots (they call it an XGA panel but it's really XGA compressed). This panel also has both composite and vga inputs (woo!), a remote, and 'fit to screen' options for 4:3 broadcasts.

Remember when dealing with many of these smaller panels the resolution is given in dots, not pixels. It's easy to get deceived this way because on the horizontal resolution each dot is actually just one of the RGB colors. If the resolution is 2400x480 dots you would get the actual pixel resolution by dividing the horizontal dot resolution by 3, giving you 800x480 pixels.

All of the cables are real wires, only one FFC which is on the LCD panel and should not be a problem. The main cable that connects the LCD to the brain unit might need to be lengthened depending on how you mount the input connections. They are all real wires though and would not be that hard to do.

BenQ T502 mam rozebrany, je skoro uplně stejny jak BenQ 557 a 567 FFC jsou jenom zespod...

Neznáte někdo náhodou tento monitor? Je to Proview (MAG) LCD 15" UK- 513E/ 1024x768/ 400: 1/16ms. Zajímá mě, jestli se hodí na stavbu DIY projektoru (Jestli nemá FFC problém atd). V tom dlouhém přehledu, který tu nade mnou napsal Locke, není. Díky.

[Locke]

Resis kraviny. Kup si neco, co overene je. Ja jsem to neudelal a pres 2 mesice jsem resil ffc problem. A to jsem mel jeste kliku, ze to slo. Sice mam tedka jako odmenu DVI, ale nevim, jestli bych si znova takovy risk hodil.

[lada571]

Tak jsem si svou vlastní neopatrností ulomil kousek páskového přívodu u svého LCD Benq 557 a tudíž šel do kytiček (slušně řečeno) . Nebylo to při rozebírání, ale při běžné projekci mi sjela stínící lišta a dílo dokonala. Jsem vůl, příště všechno lépe zajistím.
Jinak vidím ,že se po ,557 a 567 docela slehla zem.
Při prohlídce té mrtvoly, jsem s údivem zjistil, že z jedné strany je na LCD jakási fólie , která jde celkem snadno odlepit. Je celkem i tmavší takže by to mohlo mít i kladný vliv na projekci. Zkoušeli jste to někdo? Nevíte jakou plní funkci? (rozhodně né transportní)Pokud to už někdo popisoval tak sorry.

Myslím, že to s těma 17kama trochu přeháníte... Cena pres 11k za LCD?
Když tomu pak připočteš cenu za optiku pro 17tku, zdroj světla tak už se ti pomalu vyplatí koupit origoš projektor za 25k. Sice nebude mít takove vysoké rozlišení ale bude o hodně menší, tišší a profi (dálkáč atd).
Podle mě je nejlepší na stavbu 15ka nebo s 1024x768 a dobrým kontrastem. Do úhlopříčky 3m by to mělo stačit a když budeš chtít víc, tak stejne budeš potřebovat silnější světlo než 400W. A to už by byl pěknej žrout
Ale jestli nevíš co s penězma...
