Ceiling Mounted Projector, How do I keep the HDMI lead and power cable tidy?

I Have an Optoma projector and the cables are connected on the right hand side of the projector so naturally the wires protrude quite obviously from that direction. What is the best solution for keeping the cabling tidy? I anticipate adding a mains socket onto the plasterboard ceiling and a HDMI faceplate to connect a short HDMI lead to the projector and behind the scenes I will add a 25 foot long HDMI cable that I have to connect to my amplifier. What have people in these situations done in terms of coming up with a solution?

Projector Light Bulbs are too expensive, Lets make an LED based one!

The idea is very simple PRojector Bulbs last average 2000 hours and cost $500 plus dlls. Lets make an LED based projector that will last at least 15 times that and cost under a hundred.With these: http://www.lumiledsfuture.com/products/line.cfm?lineId=2And this instructable:https://www.instructables.com/id/Power-LED_s---simplest-light-with-constant-current/Yes, light issues due to wavelength variations are expected as well as fan issues but all is needed is an old projector and +/- 10 high power LEDs and lots of instructa- bility.I am currently hunting for a damaged projector to experiment with...Please feel free to commentCheers!

It's out of warranty so i don't care about it. The problem with it is that it started to get hot until one of the RGB connections got burned to ash. The rest is working fine. Any ideas what i could do with it?

DIY R2D2 projector

Hi All, So I had this idea of putting a pico projector into an R2D2 body so I can recreate the Princess Leia Hologram moment. I wanted to get some suggestions on what sort of materials I should use to build the body of the R2D2 droid. I see some people mold using styrafoam and I was thinking of going that direction but would it be better to use something sturdier just to house the projector? I also want something that would look cool but I dont have a 3d printer or any experience using plastic molds.  The projector is an AAXA p4 pico projector: Dimensions: 141*71*31 mm  Weight: 0.4 lbs Anything tips to keep in mind before I start construction?

Multiply your projector image with a prism & mirrors

I am experimenting with the idea of having several "cloned screens" out of one projector. The principle of light being split by a prism may yield very good results if colors are correctly displayed when using the prism with two mirrors to split the light in two directions. I will try this with an overhead projector first but if anybody has any suggestions please feel free to comment. Having the same image duplicated has a lot of advantages for projected movies in the park and businesses. Superbolw! Hockey! times two!

Overhead Projector

I have 2 overhead projectors that blow their bulbs. At $18-20 apiece I don't have the money to experiment with them anymore to figure out why. Has anyone got an idea how to convert one to use something like a standard Halogen or Xenon light? I would also need to keep the fan functional as well since any strong light is going to get very hot. I use them in my fiber art studio to project ideas onto paper for patterns.

Short throw projector w/ auto pwr on/off

OK- looking to upgrade an exhibit that is currently using two old kodak slide projectors on an image blender to a screen that is only about 5' from the lenses. This is a rear projection scenario and I need the following criteria met: Projector must be capable of throwing up a 62" diagonal image from only about 5', maybe a few inches less. The projector must be able to be programmed to turn on (main and lamp power) and off at certain times. Whether this is done via the firmware (menu settings) in the projector itself or via RS232 commands is up to you but I don't know much about RS232 software and its capabilities as far as interfacing with a projector. I think there might be some projectors out there that automatically power on when a source is detected as well, perhaps this is part of a solution?? The application is as an exhibit in a museum. We can't afford to task someone with physically turning this on and off every day so if the process can be automated, great. This exhibit will ideally rear project an image to a screen that our visitors stand in front of. The image can be supplied by either a looping DVD or from a PC app such as Powerpoint as they are static images. One concern at power off is that power is initially only removed from the lamp of the projector and then from the fan after it has cooled the lamp sufficiently. If all power is removed from the projector at once, the fan will not run and the lamp will fail prematurely. If there are solutions outside of the box like other display technologies that I've not thought of, please share. Large plasma and / or LCD screens of that size however are cost prohibitive. Any help would be greatly appreciated. z

DIY Small Image projector PLEASE HELP!!

Hi there, This site seems quite informative but still couldn't find what I am looking for, I really hope you guys can help me. I am actually trying to achieve the exact opposite of what most people try to do with their DIY projector builds. I am trying to make a "small image" projector. I have tried using all kinds of combinations of focal calculations but cant seem to get the result that I am looking for. I will be honest with you, I am very new to this and still acquainting myself with it. I want to build a projector that can project an image as small as 10mm across to as large as about 50mm - 70mm across without loss of image clarity. I also want to be able to project the image from a short distance, up to maybe 300mm away. I will use a 7" LCD (1280x800) and want to be able to build this projector no larger than an A4 size sheet of paper. is this achievable? if so, how would I go about building it? would you be able to give me any advice, ideas? Any ideas are welcome as my head is about to explode :-( Cheers Jon

I want an older model/gently used projector...

I was wondering if any had any advice/sources on how to get an older model/used projector. I am using it to mod a big screen to keep using the large screen without the expensive and near-impossible job of fixing the inside circuitry. I am not too concerned with HD capability, since I will only be using it to play old video game systems (non-HD), so all I really need is Red/White/Yellow A/V input and a resolution of 640x480 max. It has to be NTSC compliant, so somewhere in the US or Canada would probably be my only choices. If anyone has any advice, it would be much appreciated!

1 bit x-y scanning laser projector?

A lot of the laser projectors I have seen have problems with seek times and stability. This guy seems to have done pretty well. Would it be possible to create a scanning laser projector with a single bit input? Replace the x and y galvo(or any other type) scanners with motor powered wheels rotating at a constant speed. This would create a filled in square of laser light. Then all you would need to do is send an off-on signal to the laser to create an image. It is the same principle as a black and white CRT TV. What do you think? Edit: I think one motor should be stepper and the other permanent magnet. If both were pm's it would only create a diagonal line. The pm motor would scan from side to side while the stepper would tick along at the refresh rate. I guess you are kind of running into the same problems as you would with traditional galvo scanners. Edit (again): With a high speed motor from a dremel (max 35,000 rpm) you could only get about 130x100 pixels with 24fps... hardly the best projector. Not to mention the extreme vibration you would have to deal with if you didn't balance it correctly. I guess I kinda answered my own question.

I'm getting seriously frustrated with this DIY iPod projector.

I am trying to make a video projector for my iPod touch using a cardboard box, mirror and a magnifying glass lens. When I put my iPod over the mirror, it projects onto the wall but I can JUST vaguely see the picture. It's not clear at all. What do you guys suggest? Smaller mirror? Moving something closer or farther to the lens? Smaller lens? It's really starting to p*ss me off. I want to know what some of you might recommend.

using 12v 200 mA max trigger coming out of my projector. How many watts can I safely hook up to it?

So I have a Panasonic Projector that has a 12v 200mA "max"  trigger on it that I would like to hook up some LED's to it.  The LED people state that each module uses .72 watts (less than a watt) per module and I would like to hook up no more than 10 modules.  Or does anyone else have a way to do this?  I was also looking into a 12v sensor trigger.

Is it possible to display a video game system/dvd player through a cheap projector?

I want to find a way to project my video game systems and dvd player onto my ceiling, so that I can play/watch while I'm laying in bed. I do not have the money nor the inclination to mess with an actual projection tv, and in any case, I doubt one could be configured to do that. The best idea I've come up with is to somehow run my systems through my computer and use a computer projector; this would also have the benefit of allowing me to surf the net from my bed too. Does anyone have any ideas on how to do this, or better alternatives? All my systems have standard red-yellow-white component cable outputs, and I have a regular tv I can run the audio through if need be.

How can I make a cheap projector screen and free-standing frame?

Dear all, recently I commissioned and received a portable-ish movie projection unit that will let us show movies almost anywhere - in back yards, against buildings, in parking lots, and so on. It's designed for a guerrilla cinema experience for the community. See here for more information and a cheesy video I made for it. However, there remains one big issue: The screen and its frame. This is for the occasions we won't have a white blank wall to use. Can you geniuses come up with any suggestions? There are a number of features that are necessary in both elements:- 1. The screen Lightweight Cheap-ish Rolls up Doesn't easily crease, dent, rip, etc Isn't easily damaged by a small amount of fog/rain Can accommodate up to 12ft wide 16:9 images 2. The frame Lightweight Cheap-ish Can be quickly and easily disassembled to be carried short distances Is adjustable in terms of height and length (not essential, but would be nice) The screen can easily be attached to it Do you have any ideas as to how this would be possible? If so, I'd really appreciate it. Thank you!

Near Wall Wide Angle Projector

Sony will be releasing a 4k projector called the 4K Ultra Short Throw Projector, later this year or sometime in the future. It's a very nice looking setup of having the projector built into a cabinet that sits right along the wall it's projecting on, freeing up walking space. The only problem is it will be $30,000-40,000. I'm curious to see if it's possible to build something that accomplishes the same setup with current projectors, being able to project a decent quality image at a large scale from only a foot away from the wall.
