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.

Projector length of tube? Answered

I was curious if it's possibly to extend a projected image, from a projector (like tv/computer) down about a foot of tube. Tube would be 1 - 2 inches wide. If this isn't possibly what would be the smallest width the tube would have to be for it able to go down a foot of length?

Laser square projector

I work in a manufacturing facility and we've got a lot of forklifts that are buzzing around everywhere all the time. there's an initiative to make it safer for forklifts to interact with pedestrians. one of the ideas someone had came from another facility where they have these blue spot lights on top of the truck that project a blue dot in front of and behind the truck. you see the blue dot and you know a truck is coming. there's some concern that this might get missed by a pedestrian. a thought came to me, being a nerd, that we could use something maybe a little easier to see. I looked in to some disco type laser displays that you can display custom graphics with, but there's concern about how sturdy they are or how long you'd actually be able to use one (whatever it is would basically have to be on almost 24/7). we've got several Motorola barcode scanners, and the long range models (mc 9190) have a feature where it projects a red square to show the area where the scanning will take place. it's a solid red square, not just a perimeter, that scales up with distance (it's like 4"x4" if you're within 2' and goes up to a pretty large size the farther out you're pointing it). These scan guns are way more expensive than this project calls for of course. Does anyone know of a source for JUST the imagers for these things? or could anyone suggest a way to replicate the effect...a big red square on the floor, with other equipment. needs to be able to run for a long time, hopefully could be powered by a 24-36v DC source, possibly motion detection (though not really necessary)

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?

video projector won't work Answered

Hello, I have been trying to get a Sanyo Multiverse to work with a 20w chip LED. I may have tricked it's motherboard it into thinking it is powering a bulb. The projector stays on instead of turning off when the bulb was missing. I put the led chip where the bulb was, and turned on the LED on. I saw a yellow light. If I tilt the chip inside the light housing, it will change the colors projected. I could not get a change in color as I pressed buttons like menu or input. Is the lcd not getting a signal? The LCD wires are plugged in all the way.

Using a projector with a timer switch? Answered

I am trying to set up an art installation which will involve a projector projecting a video piece in the middle of the night when unattended. I was planning on connecting it up to a laptop and somehow using a timer switch. I realized though that the projector may go to sleep or may not work using this timer switch option. I would set the video projection up with blank space on the video to correspond with timer so that for example if I wanted the projector to come on in five hours time I would put five hours of empty space at the start of the video meaning that whenever the projector comes on it is timed with where the video is at that point and the video will play. I know there are holes all over this so any advice would be much appreciated! Thanks, Rachael

DIY Projector bulb problem ?

In reading some of the instructables on DIY projector lamp replacements I decided to give it a shot. So I purchased a Proxima Ultralight LX1 off of ebay, and when it arrived it contained no previous bulb, so I purchased a MR16 style 100 watt halogen bulb and installed it (with a seperate power supply). When I started it up and connected it to my laptop it worked fine for about a minute or so (give or take) but then the image went blank (not the bulb but the LCD screens showed blackness) for five seconds, then the image popped up as nothing had ever happened. I have tried everything to prevent this, other computers, killing the ballast (which is quite easy, only one wire to disconnect) different video sources and no dice. But I do know that it has nothing to do with the light bulb because it is on a completley different power supply and is not connected electronically to the projector in any way, there is something wrong with the controls of the unit Any Help would be appreciated, Thanks Bwpatton1

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!

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 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

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

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.

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.
