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.

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?

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?

Hiding ceiling projector

UPDATE! made some progress and have it all set up, its in the finishing touches area now. :) Items used- -12 in AC linear actuator -3 way switch - 4x draw slides - MDF - PVC - ceiling tile - various sizes of wood for frame for the actuator. ______________________________________________________________________________________ I have an idea for my ceiling mounted projector to hide in the ceiling tile and then lower down when a button is pressed. however I have no idea how to execute it. in theory I would need a motor to pull up and lower down the tile that the projector is mounted to and then run the cables down the wall to a switch. but I turn to you instructables to tell me how to make the motor stop when the tile is low enough on the cable and when it rises back into place with the other tiles. Sort of like an automatic window on a car. with the push of a button it goes into place and when the button is pushed again it rises back.?

Pinhole Slide Projector

Hi! I have no idea whether this is the right place to post this topic, but it does say 'burning questions' and that's what this is, so here goes. :-) I've had this idea for a kind of pinhole lense slide projector. The (very basic) diagram is pretty self explanatory, and I was wondering if anyone's tried/heard of anything like this, and whether it could work? Do you think a 100 LED torch would be bright enough? Also, if I'm right in thinking that LEDs don't get hot, there shouldn't be a risk of overheating/fire should there? Thanks! Looking forward to hearing what you think! :-)

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)

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!

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

Just a thought i had when i saw all of these led projectors on here. and then i saw a ds sitting on the table then i though, what if there was a such a thing as a ndsl projector?! how i believe it would be contructed, at  least the case anyways, would be to detach the top screen from the bottom. then to use the screen as you would any other in a diy projector, keeping in mind that it has to stay connected to the ds. then build half a ds arcade stand for the ds, and build the rest of the projector. would this be plausible? or would it be impossible?

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.

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
