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! :-)

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

Candle Powered Shadow Projector

If anyone has seen the movie "Sleepy Hollow" starring Johnny Depp, you must have noticed the scene where the little boy lights the candles in the punched tin can, the can starts to spin from the heat of the candles, and the punched holes in the can are shapes, a cat, a witch, a tree, etc, and these shapes are actually projected onto the walls, projected and spinning very, very slowly.  As you know this movie is set in the late 1800's, so it is not any kind of electrical thing.  I would love some ideas on how to make one of these, I don't even know what they are called, I have looked for one on ebay and here on instructables....I've been calling it a "shadow projector" but that probably isn't right.  It is an awesome little contraption, great for halloween or anytime, depending on the theme of the pictures punched on it.  Any ideas/photos/clues would be appreciated.  Thanks!

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!

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

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.
