Home Made Projector

[XBLASTR2]

Nice. 9/10 The one problem I'd say: A bit dark.. but well done! I wouldn't say very many people could make their own, including me :/

But a great job, it does what it needs to do, so your projector mission was a success :D

I just wish I could make my own, if I had the parts.. xD

[Munymuny200]

how bright is itndo you know

best

[jr52990]

Awesome project... quick question though.

How long does it last? and what problems (if any) does it have?

[StrykerTrace]

@jr52990 Bulb breaks from time to time, can't recall how many hours it should work. Problems is more on the aesthetic side, size, placement and such.

[jr52990]

@StrykerTrace so you haven't had any problems with the screen overheating or warping? if not I'm really considering making one of these but I'm just wondering if its just going to break. How long have you been using it?

[StrykerTrace]

@jr52990 The fan helps with the heating, put more fans if you're afraid of overheating. The overhead projector itself has a somewhat noisy fan inside it also, for the bulb. No warping detected. I don't have this setup anymore though but no such problems when I did, can't recall how long I actually had this in use.

[jr52990]

@StrykerTrace Oh ok... cool. Thanks for telling me, I think I might just use this as my next project.

[hamsterball27]

when i trd to make one the screen cracked when i took the metal case off it

and the second screen got blac blobs because of the heat as it was used for about 3days non stop

[iSmokeCronicUshld2]

begining nazi kill ftw!!!

[cjoenic]

im having problem to separate the backlight of my 15inch LCD from the screen... the screw kinda small.. x(

[outslider1]

Nice work. This ventilator on the left at 0:22 is there to cool this device? Or it's not important background?

[StrykerTrace]

@outslider1 Yes it is for cooling, computer case coolers could be used but I didn't feel like wiring them so I used a regular fan.

[pleschinski]

@outslider1 overhead projectors get VERY hot, and that is bad for LCDs.

[sofranko101]

u no he dead

[MrDexter9i3]

How long can a projector like this last... until the screen burns out or something...

[reboothater]

sorry thats no foreign light sources windows open, alarm clock leds on,etc.

[reboothater]

it will help to both focus the light into the mirror/projector lense, you will want the top covered, but obviously not covering the projected image comming out of the lense/mirror. a box should do the trick at vastly improving the image and making the room as dark as possible (alarm lights,window lights comming in etc.) youll want the room pitch black.

[sofranko101]

@reboothater ur gay

[reboothater]

when you have something producing a faint image, even the smallest amount of light causes fainter light to wash out and not look as colorfull or bright. you notice you can see light off the projector unit on the walls.

[reboothater]

dont cover up the projector lense at the top but just make a cardboard box top, watch for heat, you can probably build your own bottom casing and put fans etc. to deal with it.

[reboothater]

up to the glass lense i mean.

[reboothater]

just a thought you will probably improve picture quality emmensly by putting a light tight box on the top up to the glass project (at the top of the unit). you will want to provide ventalation if you do that, most likely thats whats causing the picture from not being as spectacular as it can be as the light from the overhead unit is washing out the faint projector projected image.

[freakzilla3333]

@reboothater That's true, I noticed that the contrast was much better after making an enclosure, my diy projector was originally like this one but with a pc cooling fan on the side. Anyone who wants to see what a basic enclosure looks like; just check out my video on my channel page.

[olger05]

it will over hit a now this even whit your ventilator its not that great

[MrArando]

That looks awesome, i want to try that, but I have 2 questions.

1: Will The Picture Appear Backwards

2: Can I hook this up to a dvd player or a PS3?

Thanks

[StrykerTrace]

1. No, unless you put the screen upside down.

2. Easier to use a PC as a DVD player. Depends if the DVD player and display have matching connections.

I'm not sure about the PS3's cables. Depends again if the screen has a VGA, HDMI or DVI connection and wether a PS3 can be connected to any of those.

[TheTIprogrammer]

@StrykerTrace ps3 can connect to all except DVI

[italianguyone]

@TheTIprogrammer uhm thast a lie i have a dlp tv with dvi and it works great at 1080i and ive used a projector with a dvi input all u need is a dvi to hdmi adapter from walmart 15$ ohh and ur thing has to be hdcp compliant aka digital hackshake for ps3 to appear on screen

[TheTIprogrammer]

@italianguyone Well I meant It doesn't have a DVI port.

[tyga42]

@MrArando I have 1 question.

1: Are you that stupid.

[Guitaranator2]

the only thing that i dont understand is how to reactivate all the wiring for power, hookup, etc. please explain

[StrykerTrace]

Check how they are wired when you remove the panel from your display then put it back together without the casing. I had the controller board found inside the casing taped to the back of the OHP. Vga & power cables are connected to the board.

[StrykerTrace]

You can see a cable going from the display to the controller board at the back of the OHP at 0:13. All found inside the display casing.

[malcommerriweather]

Can you enclose it as to not have as much light emitted from the base or would it just get too hot?

[CoolmanTV]

wtf how did you make that?

[weedfan]

is that really what a 100" looks like? thats huge! or is that bigger than a 100"? ive never seen 1...

[StrykerTrace]

Yes it's 100" in 4:3. The letterbox black bars on the movie hides the total screensize.

[YaTuberculosis]

- Looks like a quality film... :)

[NIKOLA91i]

perfekt

[PremiereDirector]

A suggestion for you... Instead of a pedestal fan, I've seen people rig up 80mm PC fans to the projector and have the LCD panel elevated above the projector glass (which you've already done), and power the fans with an external hard disk power pack, which you can hard wire to the projector itself.

Good projector you've made though :)

[avatar6889]

sorry im not the best when it comes to technology so i ask a favour. i have a ohp and lcd screen, what else do i need??

[beerpongmasterss]

@avatar6889

I think lcd wont work, TFT would be fine, just get one and open it up, dont cut any wire, leave them all intact.. just srew off all plates till you can see trough.

[smrtsTV]

Hi, I'm making the same type of DIY projector with an Overhead Projector but I can't Find a over head projector that has more than a 11" x 11" display and any LCD's i find are bigger, advice??

[StrykerTrace]

If you want to use it for you computer desktop you got a problem. If you use it for movies only some things can be done:

1. Turn the lcd display vertical on the projector, most new graphic cards can turn the desktop the same way.

2. Some media players can shrink the fullscreen, this way you could fit the movie to the width of the projector, BSPlayer is one.

You will of course loose pixels both ways.

[goodpieX2K]

one thing before you do this is: make sure you have a nice pair of speakers!

[smudger909loop]

this is a mess . its to dark for a start and for gods sake a projector new is only a couple of hundred pounds new . what is the point in this and all the mess that goes with it . i see no point to tell the truth

[alphabravo28]

Look at it this way, a replacement bulb for a projector is practically as much as the projector itself, whereas, a replacement bulb for the overhead projector? £15 - £50.

[damianlang]

And the satisfaction of DIY :)

[jaysteinbourg]

First of all smudger909loop when you make your own projector you get a great sense of achievement and when you bring your friends around to see it they will want you to help them build one too. A couple of hundred pounds may not be a lot to you but for me its a holiday or my rent for a month which is a lot. The difference can be compared to baking a cake and sharing it with friends and then buying a cake and sharing it with friends, the latter just doesnt give the same satisfaction.

[PremiereDirector]

I agree with you 100%. I've actually wanted to build one of these for ages.

[chizzychizzy78]

hey man how do i hook uo da computer.dvd player to the screen?

please respond!

[StrykerTrace]

VGA (or DVI) cable goes to the screen just like a normal monitor. If you want to play DVD's use software player on computer.

[chizzychizzy78]

Ok i get it now... thx man

[antonbergjr]

ok thanks

how much did it cost u to make this usd

[StrykerTrace]

I got the screen free from my workplace. (It had some damage on the buttons, worked fine when the case was removed.) The projector I bought used and payed about 40 USD for it.

[antonbergjr]

im thinking about doing this

looks realy good

how long to the bulbs last

and are they expensive

Anton

[StrykerTrace]

Bulbs last pretty long, just keep your fingers away from the glass surface of the bulb and don't to light it "on-off-on-off..." quickly.

Cheap bulb compared to home projectors, about 30USD on my model.

[hoagtech]

really i heard two bulbs gives you a big spot in your image unless theres a way to focus them both on the center of your fresnal. let me know if it works

[StrykerTrace]

The change using two bulbs is hardly recognizeable in lumen. In both cases the bulb(s) can be seen on the image on darker videos. You can see it on this video if you look careful. Doesn't annoy me.

[hoagtech]

Nice results! did you replace the ohp bulb or is that stock?

[StrykerTrace]

Stock bulb 36V 400W, it's also possible to use two bulbs to increase luminance but only got one in use.
