Very briefly just want to offer a personal thanks to all of the diy minded individuals that share this site, yes I am talking to all of you, from the super intelligent video freaks to the passer bys like myself who are just shocked and glad to see others with similar interests, THANK YOU ALL sincerely for the shared info and the help that you have provided that is secretly absorbed by all ...
I have owned several projector mods, and started like many with the overhead /panel projects, however even with xga res on the proxima 920 and a 4000 lumens overhead, I was not satisfied with the intensity and brightness, which led to my current finished project,
Provided are a few pictures of the setup--
> Vintage Kodak carousel slide projector modified $ 4
> 2.5 inch lcd stripped from the
intec controller screen for ps2 (see pic) $ 25
> Ps2 to 2 rca audio and 2 video wire $ 8
RESULTS:
Overall I am very satisfied with the intesity, 300W halogen style bulbs which simply pop in and are the same as the overhead type !
The color and brightness are fully adjustable on the control board ! The picture looks excellent once the focus is ever so slightly "off" and any remaining screen door is diminished, the res for this panel is surprisingly high, hard to find the actual pixel count anywhere, but definately 235x300 or so as this lcd looks great at 45" diagonal but should not exceed 55" , Overall very pleased, Thanks to all for the many posts !!! |

| This type of slide projector is easy to find, very affordable, and easily stripped to accomadate the 2.5-2.6 inch lcd as well as the control boards for a totally integrated and portable unit of your own ! ... |

| helpanewbie |
Thats pretty impressive considering the panel. Better contrast than I'd expect.
Nice Job |
|
|
| dale cooper |
| almost forgot the 2.5" lcd, stripped from an "intec" product, also similar to the "hipgear" ps2 controller screen ... |
|
|
| dale cooper |
Just a footnote, this setup can accomadate any video game system, any dvd , vhs movie, with no macrovision issues (the secret enemy of early produced panels !) and plays cable tv like no ones business, nice !
Now I would not recomend this setup style for all you super xga types, yeah you know who you are, the never satisfied... anyway the res is great for the rest of us ! Leave some pics of your similar projects or let me know if you need questions answered... |

hey dale copper,
nice results and a good job.
could you make some pics of the stripped lcd and write a "how to connect" ?
maybe this one is a sub for the psone-5" tft.

neither the intec nor the hip gear controller is available in europe.
i've searched and found it on walmart.com, but they don' ship outside the u.s.
@dale copper, where did you find it?

Hello, If you are looking for the "intec" or the "hipgear" brand ps2 controller screen, try Kbtoys (24.99) Walmart (39.99 US only) or any video game re-seller store, Also the beauty of any smaller 2-3 inch lcd, even the portable tv type ( make sure its "tft" and high res) is that a carousel style projector can accomadate the panel and the control board mess once the lcd is stripped >
>>> My project consisted of stripping the lcd which has a delicately connected control board, speakers (removed), backlight (removed), another small control board with the "brightness", and "color", adjustment controls (important), and then opening the underside of the slide projector, and disabling any automatic lever moving operational sliding, noisy metal parts, Then with the new space simply insersting the lcd assembly inside the now upside down projector case - IMPORTANT, the lcd's horizontal and vertical arrangement must be considered before any placement into any slide proj is considered - that is when the lcd is inserted you focal lens from the slide proj will, FLIP and REVERSE your lcd image thus forcing you to insert the lcd just so that you see a correct image, ALSO, the 4corner alignment will need to be dead on ! that is , the alignment of the lcd will need to be parallel with the focus lens ! any tilt on any corner will cause focus problems, and this is the only "work" part of the project, I used a combination of cardboard, masking, and aluminum slides modified as tracks as a guide to KEEP THE LCD IN PLACE, once set the slide projector can be closed and become portable ! Nice little unit ! |

Brilliant, this is about the coolest thing I've seen.
This may be a dumb question, but how do you wire up the LCD, power? video? |
|

| dale cooper |
Hello, GOOD QUESTION, experienced diyer's will understand the relevance of this info, others should listen up >
Any LCD panel is only as good as the > 1. Resolution > 2. Video input capabilty > 3. for me, Size, I did not want a large box in my lap as I watched movies with two other girls, the girls may get jealous and begin making out and I cant have juices get onto my projector , haha, anyway seriously - This 2.5 inch " intec " panel was EASY because once stripped from the ps2 controller only one cable was needed to make the lcd play ANY video signal, the cable is a 3end ( ps2, xbox, gamecube) connector and on the other end, 4 rca composites ( 2 audio, 2 video) this was a WALMART purchase and can be found anywhere, for 5-10 dollars , thus making this particular lcd compatible for ANYTHING, video games (obviously) dvd's vhs, cable, etc., Also, a portable tv screen with an 8th inch video input may actually be best if your interest is strictly movies |

I'm very inexperienced when it comes to DIY video.
How to you power the LCD? Battery? |
|
|
| dale cooper |
| Hello, most lcd screens including this one, are powered with an A/C cord that plugs into the wall and also plugs into the LCD either directly or on the cord, it is really very simple to power the lcd units, generally the issue is not power, but signal, video signal for dvd movies, or video games or other computer monito video signals, etc. ,.... |

impressive! truly impressive. With a total cost of only 37$ US?
I might look into this. My father wont let me put a big projector into my bedroom, perhaps I can talk him into such a small one. Plus slide projectors are really cheap on ebay, you can get a decent one cheap, with autofocus and everything. |

I just bought the hip gear controlled for only 20 canadian dollars, and now I need to know what is the brand of the cable needed to make the RCA input.
By the way, thanks for this great idea! |

Hey no budget, here is the photo from walmart of the style of cable needed to preform this lcd magic, also, the brand is insignificant, others make it for le$$, Also I forgot to add the DaLite "Jet" glass-beaded projector screen , $ 4
> Just a note, the autofocus feature for mine was disabled in order to expand the slide slot where the lcd fits,

I am completely amazed by what you have done. My roomates and I have every intention of trying to replicate what you have done. This is just simply amazing. My utmost respect to you and the rest of the diy-ers out there. I look forward to trying to do what you've done and hope you wouldn't mind me doing so. Any tips on how to get the screen to stay in place for a noob? And also look forward to the pictures of the interior.

Hi,
Exactly what I've been thinking about.... just needed someone to step up first I guess.... nice work !!!
Couple of questions, what is your light source? Do you need or use a heat glass or something of that matter? And, do you need that cable specifically to use it -I mean, could you just use a RCA-mini jack style cable from the DVD player to the screen?
Thanks. |
|
|
| PackerBacker |
1. The light source is the OEM engine from the carasoul slide projector
2. No need for heat glass, an lcd panel melts at a higher temp than a plastic slide ;)
3. Umm yeah, you need that cable thingy so you CAN use regular rca jack, unless you just want to play games. |

| One other question is where did you find your projector and screen? |
|
|
| [Sv3] |
Hi again!
I still need to find a projector, but I was so exited about this thing that I opened the controller so I could see how to strip-it. From this point, I learned two thing: Number One, I totally suck when it comes to electronic equipment, and Number Two, I don't have any dawn clue about how to connect this thing.
So I wonder (and I hope i'm not the only one) how do you pull this off? Do you need to cut any wires, and if so which ones?
I know this is really newbie stuff, but that's all I am, so the most info I can get, the better it is for me. You know I just don't want to ruin my LCD...
Thanks in advance! |

Yep I tried a long time ago same setup
with a slide projector but - I used a old casio
hand held TV - I think it was TFT - but low end
the tv was made in 1998 - I was able to get a projected
image but it was blocky as heck - the pixels looked like
the size of lego blocks or biger at about 4 foot by 4 foot
- Ugly - but then I broke the LCD connector and chunked it
image was upside down - I was trying to get it right side up
when I broke the lcd cable - just not long enuf, cable cracked
I got my idea from someone else that had done it years before me
and posted in a forum
Good work - looks cool - I guess LCDs are getting better |
|
|

| Moose, Thanks for the heads up, ill try to get down there before the sale ends (21 of october) and pick one up. Will it yeld similar results as the lcd used in this project? |
|

| dale cooper |
Here's a little help >
When opening the "intec", or "hipgear" screen pad, you will need to meticulously examine the construction of the unit as it reveals iteself through your work of stripping it open (gently), the only wires that I dis-connected were the audio signal wires going to the small flanking speakers that I removed, all 8-9 multicolor wires that connect the controller - BE CAREFUL not to disconnect any other wires that are power related as this may end you project there, and the backlight, When you are opening one of these controller screen pads, all of this info will become obvious in front of you as long as you think your way through it. At times your dis-assembly will look like a long controlboard-wire-board-wire-board, mess, this is good,
When buying a SLIDE PROJECTOR , try to find the carousel style as they are generally newer and have more internal lcd room, once you remove some of the slide mechanics and metal moving parts inside, Now the only work to do is to is the proper orientation of the lcd panel and making the lcd rigid in its position so that once the projector is re-assembled the lcd will not shift, let me know how your projects are coming along, thanks |
|
|
| dale cooper |
OOOOHHH, yeah, here is a TIP on how to avoid ever tearing your lcd to controlboard wire, these are generally paper thin and can easily be torn in your lcd stripping process, some have discovered this the hard way, and there project ended way early>>>
Cut a small length of electrical (thin, black) tape that is slightly longer than the lcd connecting wire, then gently lay it flat over the wire so that the ends touch the lcd and the control board, this tape will create a reinforcing strength while allowing for a bit more rotational movement, and preventing a tear, remember any tear, even the most incremental, and not visible to the eye, can result in altered preformance and most likely ruined, trash, Unless you kept your receipt and/or you are a sodering expert, hope this helps
>>>ALSO, be sure to cover, or tape the entire control board assembly before you permanently insert it into the projector, this will PREVENT any electrical interferance that will effect your lcd with a glitchy image, and will protect you from getting burned or electricuted during your build, post pics soon |
|
|
| [Sv3] |
Thanks for the advice dale!
Still have a question for you. About the RCA cable, where do you plug it to the screen? Do you need to cut the controller cable and connect it with the RCA one? Or is it directly connected to the screen? Does it require any soldering? (what a newbie i'm am :whazzat: )
I'm quite puzzled :confused:
Can't wait to see more pics of your setup! |
|
|
| dale cooper |
OK connectivity of the "intec" and/or "hipgear" controller with screen goes like this, please see pic below for visual aid, VERY EASY
The controller screen has a single wire coming from the back of it, the intec model does not have any inputs on the device just one wire coming out the back > THIS WIRE opens up to a power connector, an Xbox, Ps2, and gamecube females ( ready to plug into these game consoles) VERY SIMPLE >
The adapter cord shown is the purchase needed to connect your dvd player, tv, etc... into this lcd , once purchased this connectivity is self expanlatory and quite simple really >
and once you connect the two, you now have Rca's ready to plug into your video scource of choice ! |
|

| Serow |
I picked up a hipgear controller and the converter cable.
Does the s-video work as well, or just the rca's? I personally can't get an image from the s-video, haven't tried the rca yet.
Thanks! |
|
|
| Serow |
To answer my own question: no, the s-video will not work.
I disassembled the hipgear controller. I found out that the adapter cable is not required, if you are willing to cut a few wires and do some easy soldering.
There are only 7 important wires that go to the lcd control boards: 2 video, 3 audio, and 2 power. I will post the color code once I get back home. These can be soldered to a few rca female connectors and a DC power jack, which can be mounted on the outside of the slide projector.
Cheers! |
|
|
| I_eat_flowers |
| Will this lil gizmo work with PAL devices or will it work with NTSC only? |
|
|
| Serow |
7 wires go from the controller to the display board of the hipgear controller:
Video:
Yellow = RCA pin
Brown = RCA shell
Power:
Green = DC ground
Orange = DC power +12V
Audio (optional for a projector):
Red = Right RCA pin
White = Left RCA pin
Black = L+R RCA shell |

|
| [Sv3] |
Oh man! I feel so *******ing stupid!!!
I've bought the RCA cables, and now I understand what you meant by ''self-explanatory''... I can't believe it's that simple!!
By the way, I've got all I need, and a couple of hours of spare time, so I'm gonna give it a try!!!
Thanks, and sorry for beeing so stupid last time :rolleyes: |

I need help here!
I've stripped the LCD and made a stand to lay it in front of the lens as I tried it, a black spot started to grow on the screen. Now, beeing not that stupid, closed the projector, and the lcd seems to have gotten back to normal.
Now, I suppose that this is due to excessive heat, as I don't know what else it could be...
Any suggestions or answers? |

| I'll jump on this diy bandwagon (what the heck, it's only like $30, and even if the picture doesn't look too great it will still be good for playing music vids at parties and stuff). I hadn't ever thought of using the cheapo and plentiful lcd's from video-game accessories, it's a great idea! The combination of the slide projector (so we don't have to mess around with getting lenses and lamps and arranging them) is excellent as well. I will report back with pictures and notes as I get them. |

| Looks like I might just try this for the money it would be fun. I have a question on the slide projector though. Any idea what watt bulb is in it, as well as focal lengths. Figured I'd try and find a brighter one on ebay. Also KBToys have 20% off all video game purchases this thur-sun if over $40, could get 2 controllers for that much. |

| just got the one for 19.99 at futureshop (btw, its 19.99 canadian, thats only 15$ us!). Its alot brighter than I thought. And I didnt need any cable to buy, i just used the original ps1 rca cable. The Hip Gear one has a ps2 av jack, both male and female. |

hey buddy,
before ordering I think we have to figure out whether it'll work with PAL-standard. NTSC is not common in Europe.
That was ma question before but nobody answered.......

Depending again on pal compatibility, but for the money I would get one anyhow. My pc can output NTSC cant it? I'll install it on the front of my pc case if nothing else.
whos up to organise me one? I'll sling you some beer money (can't afford much though lol) and copious amounts of good karma. |

A perfect sized high pressure low noise barrel fan;) , this thing gushes out air at low rpm, the air is also alot colder then a normal fan.
I recon we could make a hell small projector with one of these, with a cdm-t or similar bulb, a couple of pcx lenses and a 8mm or similar film triplet lens. Id go for a projection lens the same size or bigger then the lcd though and run it all paralelle.

Heya bodgy, it should do though id check if i wer you as some cards that have the tv out function only have one of the 2, some nividia cards have both, they normally have a jumper on the card at the back panel, though not all.

My Radeon 9000Pro has a jumper for switching NTSC/PAL for the bios and etc, but I can change the format in the drivers in windows. If I set the jumper to NTSC, but set the drivers to PAL, ill have the bios and windows logo and all in NTSC, but windows will be in PAL.

I can test the Hip Gear screen for PAL when I get home if you want (im at school rite now, TGIF) |

Hello, me again!
Sorry for all the stupid questions the other day, but now, I'm into the real thing, I've stripped the LCD, opened the projector, putted everything in place, the picture is ok, the colors are nice and all, but one thing bugs me... I just can't get all of the image, it's like there was a circle around the LCD that hid the sides of the pictures... It's quite annoying because as is, I just wouldn't watch my movies on this.
Can anyone help on this one? |

Actually you can convert it, i have a schematic around for it somewhere, you should be able to run it on vga too, though i wouldnt bother on that reso lol. Most lcds run in ntsc nativly beleive it or not.

I recomend both, also maybe your light guide or channel is too small, its probally just as easy to build your own, it would probally be finnished in about a day and smaller. besure to have a look in surplus shed as they carry a wide range of projection lenses for slide projectors, and 8mm projectors.
Trev:) |
|
|
| [Sv3] |
Ok, here is the thing, I've already put too much money in this, and I need the cheapest solution possible. I think you were right, it was meant to be 1x1... Now, I don't have any surplus shed around here, believe me, it was hard enough to find a slide projector, can't even think about some pieces...
Plus, I suck at building things, so building a custom projector is, at best, a very bad idea... I'm willing to buy off the internet for the projection lens as there don't seem to be any other way around, about the light channel, I taught I had it right until I realized a magnifying glass was in fact downsizing the light (YESS! I'm THAT stupid...) I need an easy way you know.... Real easy and cheap...
As for the projection lens, what kind of specifics should I be looking for? MM, f/??, that sort of things...
By the way, the lens I'm using now reads 3 inch, f 3.5.... |

Too bad you dont live near Toronto, I have a triplet lens here from a slide or finm projector that I tested with the LCD, and it projected all of it. I dont really need it though.
Perhaps if you wish to got BIGGER, you can get a CRT lens, I remember some science store was selling 5" ones for 8.99? and 3.5inch ones for even less. They have a VERY good light efficiency. I compared an old Delta4 CRT lens, vs a 15mm triplet projection lens, and got about 3-4 times more brightness. |

Hi all. I've been lurking this forum for a while and the idea of building a projector by my own it's very fashinating. The problem here is that I'm Italian, so it's much more difficult for me to find the needed pieces. I wanted to do something similar to this one but everything I need on e-bay costs me a lot in shipping fees(30$ the projector and 35$ the shipping!!!). Do you know if there is any German or English (i don't even try to say Italian) e-store wich sells this kind of things?
Another question. I've found 2.5" a tft screen on ebay for 30$ with 105600 pixels. I'd like to know if I'm doing well calculating the pixel's size on the wall for a 100" image equal to 0.5cm x 0.5 cm (sqrt(200cm*150cm/105600)). If I'm right i don't think the quality should be so bad, but I'm probably doing an error not considering the dot pitch.
Bye
PS Sorry for the bad English |

| I dont recommend 100 inches, unless you are going to watch it from like 500 inches away. |

| So you think 100" it's too big? I'll be ok even with 50"/60" |

| i suggest no more than 70 inches, but give it a try at 100, maybe it will be good enough. Its all a matter of prefference. |

I had an old kodak slide projector in the trunk of my car, so i got a hip gear controller, and decided to give this a try. I've already got an ohp/sharp qa 1500 set-up, and a ps 5" DIY projector going, but I'm always up for trying something that sounds so promising. so...
My questions are, now that i've stripped everything, and am getting ready to place the lcd into the gutted slide projector, what worked for you? Did you do some steel, or aluminum light stock, bent up and fixed to the top of the carousel, so that it hangs down when put back together? I will be doing front projection, so it appears I will need to pass the light through what was originally the front of the lcd. How long has your projector been operating, and have you had any cooling issues? Do you have any pics of the inside of the carousel, now that the lcd is in? I've been using a printed out overhead transperancy cut to size to be sure the lens will focus the 2.6 inch screen, and it does, so I know I'm in the home stretch.
Any help appreciated...
Thanks,
Don |

| so...I went ahead on my own this afternoon, and am glad to report, this makes a great little projector. The quality is about the same as when using the 5" sony playstation lcd in a custom enclosure, but the big difference is in the overall simplicity in the build. From start to finish, this project took me about 8 hours, and cost me about $30. The sony psone projector cost me about $100, and took about 30 hrs. I already had the old carousel slide projector. I second what Dale said about the absolute necessity to get the lcd placed exactly right. That process, and fabbing a holder for it, took about 4 hours of patient trial and error (and it is still just slightly off). This is a very cool project for someone to get their feet wet in the world of DIY projection, and Dale -you should be commended for giving it a try, and sharing your idea with the rest of us. I will try to take some pics tomorow night. |

could you perhaps post some photographs?
it would really help me (and probably 100000000's others) to build my own one. I just can't figure out how the LCD should be placed in the projector.
thanks!!! |

HEY ALL !!!!!!!!!!!
and thanks, DOCBROWN ! I am glad to hear that you and others have attempted this simple , inexpensive build ! At times tedious but overall
refreshingly simple compared to the complex schematic large builds and/or having an overhead projector in your lap, haha,
I WILL BE POSTING PICTURES TODAY OR TOMORROW, due to the elevated interest in this 2.5 in LCD / SLIDE CONCEPT !!!
Right after I vote , Sit tight and please send your pics too !!!!
I am very interested in you progress ! |

I had to fab a holder for the lcd out of some thin steel, and some wood with slots filed into it. I was then able to have the holder "grabbed" by a spring loaded clamp that now holds the lens, heat glass, AND the lcd holder in place. I used the tiny screws from disassembling the hipgear controller to tie the fabbed holder together. It is immovable at this point, and pretty sturdy. I had the projector on for about 15 min this afternoon, and one concern I'm still having is cooling. The surface of the lcd became hot to the touch, while the fan was still pumping out lots of hot air. I may put a computer fan up in top, directly above the lcd for more cooling.
I'll post screenshots once I get the cooling thing figured out. Could someone let me know if the pic link works?
Thanks,
Doc |

I couldn't resist!
I picked up a GameCube HipGear controller from Best Buy - wasn't on sale but was still only $29.99 CDN! Had it completely torn down and plugged into my DVD player in less than an hour.
Thanks to all who posted instructions - and especially wiring color codes, saved a boatload of time.
I also picked up a used Braun D40C slide projector for $7. Had to rewire the AC since cord was missing - but thing fired up first time and the bulb is still working too. It's old, but is pretty compact - think it might do a decent job. Not bad!!!
Long story short - pulled enough of the junk out of the projector to fit the LCD in. I loosely positioned it, fired up the LCD and projector - and WHAM....low and behold Harry Potter magically appeared on my wall!!!
You guys rock - I am truly in awe of the crazy ideas you come up with. I don't know how long this thing will last, but was a blast trying to get it running so far. Keeping my fingers crossed for a successful project.
Total cost - less than $40. Yeehaaaa! |
