Okay so I forgot to grab a camera...sorry...

I tried to reconnect the wire and when I powered on the unit the screen came alive. Unfortunately there was nothing on it. So I guess that one is down the drain...oh well...

I am going to hold off for a little while before I attempt doing the next one. If anyone else has had some success with this can you please post some more info?

A step-by-step would be great, but I'm not sure enough people have tried it yet. Thanks in advance!!

Hey Mike - I wouldn't write that one off just yet, I am sure it can be fixed if all you did was cut those wires. You would need to cut both of them and others to connect it to power and video anyway.

See the previous post that details the wiring layout.

If you're really stuck, I'd be happy to have a look at it for you. Might even be a good opportunity to document the whole disassembly process. I have already taken apart 2 but didn't snap any pics during.

Note to tetutigre - the PS2 controlled does not need to be attached. It serves no useful purpose for this project.

Ok - don't know if this will help - but using my very horrible graphics skills I created an image that shows how some of the wiring works. Note - the controller portion of the unit is not required. Also - I have shown the backlight wires but they won't be required - the backlight will come off before you mount the unit.

Here it is - forgive the primitive drawing. 😉


An externally hosted image should be here but it was not working when we last tested it.

Ok, you can hook this up without the rest of the controler or a adaptor for the video. Connect the wires off the lcd controler board like this to get rid of the button controler board. Yellow is video in. Brown is video ground. Orange is +12 volt. Green is power ground. The red white and black are for audio so they can be cut right off and not used. So you can cut the plug that the ac adapter plugs into and it will have a purple and blue wire. The purple is +12 volt and the blue is ground. So connect purple to orange and blue to green. And then if you have a RCA jack connect the yellow wire to the center terminal and the brown to the outter round terminal. I hope this helps.

Wow this is cool

I was all ready to do my first setup as a panel and OHP combo, but this looks cool. The only problem is, I can't find the hipgear screen pad anywhere, everyone must be buying them up for this project!! LOL!

If anyone comes accross a good deal for these, I'd like to know. I'm particulalrly interested in trying out the Xbox version.

Thanks

Ah yes but....

Do they work with NTSC? It doesn't say, and this site says PAL only.

http://www.success-hk.com/pp/item_detail.asp?itemID=C4CD9871-7242-413A-9529-5AA7C5BDF348

Unless that is not the same item

Hey, but if it works for you, they sell it cheaper.

EDIT: forget my drivel, it says auto PAL/NTSC switch so I guess it would be alright. The resolution is stated as: 336960

Well, 640 x 480 would be 307200 pixels, so I suppose that is good enough. The next issue is, how strippable is the unit? I am bidding a few things right now, but if they fall though, actually I am hoping they will now, I redivert to one of these little gadgets.

Hey,
Im new on this site, i was inspired by the first thread posted here for the HIP screen. and i went out that same day and got a projector similar to this one at a thrifstore for $10:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=3853449140&ssPageName=STRK:MEWA:IT
and i got the HIP xbox controller from ebay yesterday
my question is, the bulb on my projector is 500 watts, is that gunna be too much for this screen?
will it make the contrast worse or overheat the display??

Hi,

continuing with the thread..... I've got one question.

Will the controller board be affected if put it close to a fan coil? I'm trying to get this all set up in my little projector, but the only space available is close to the coil, and don't want to have any electrical problem or magnetic or anything like that...:hot:

I'll try to post pictures if my exlpanation is still confusing... thanks in advance.

P.S. I was also wondering, since the screen is small, that a low wattage light will work fine, e.g. a 75w dichroic lamp.

I have one of these hipgear screens that I am willing to take apart. I was wondering until I get a slide projector do you think ot would work on an ohp? I know it is small but do you think the ohp will have enough light to project it?

"I need to know too...

I'm considering to buy this one too, and since I live in a relatively small place, this is the only one available to me as we speak... "

I should note that the bulb that this particular projector takes while it is incredibly bright it only has 30hours of life!!! and thats TOTAL LIFE! this thing is from 1958!! the bulbs sell online for about 6-10 bucks but it'd probably be better to retrofit a MH bulb, or halogen. also i would recomend it if you can do that because it is a very simple layout inside and has very efficent cooling, also there is plent of room underneath for a 12v transformer and a LCD controller
once again thats this projector:

I was thinking of making on of these for kicks, but not using a slide projector.... I already have a leftover singlet projection lens...

I was wondering what other types of optics are using for this. Might I be able to use one of those hand-held fresnel lenses? I can't remember what the focal lengths are all supposed to be. (I have had my projector working for quite a while and havnt done much with it)

Also, I hate to get flamed, but might this be a time when using LEDs might actually work? If I get the kind that have a viewing angle of 10deg, and put them very close to the LCD, It might not be too bad... Although I guess there would probably be a lot of little bright spots.

I am trying to figure out if it might be possible to make this thing semi-portable, prefably not running on 120V. Maybe a large battery or worst case, a Car Battery jack.

What kind of optics would be optimal for a small throw distance and short amount of distance for the light to travel in the enclosure?

Thanks!

P.S. does anyone know how much current the LCDs consume? I'd like to know so I can figure out what kind of power source I am going to need.

Any moving image examples?

I'm getting one of those screenpads today in the mail. Now I have started work on a laptop based projector, I am wondering if it is worth proceeding with this or I might just use it with my XBox, or sell it if that is no good. I wonder if anyone has made a movie of the projector in action so I can guage the quality. Thanks if you have.
