3D Floating Hologram

Is it possible to make a 3D floating hologram like in the movies? I need help. I'm trying to develop something like this and I'm having trouble. Could I use an LED cube to make it? Or should I use glass and a projector? Or something else?

if you want to do something complicated but itll be the real deal, now we have 3D LED POV displays. its basically a lot of LEDs on a disk that spins really fast and changes the picture to create a hologram. hope this gives you an idea http://www.youtube.com/watch?v=YXlrTzrqsqA

good idea why not use bullet proof kevlar idea and use it look at the http://www.amazon.com/Mirage-3-D-Instant-Hologram-Maker/dp/B0002W3J7M
holorgram time travel back in the the early 90s awas a arcade game that made a hologram image that you can put your hand through.. no joke it was an amazing illusion and it made ppl really think we where gonna end up like in back tothe future...we have the technology just lack of fashion pazazz lol. anyway i remember it clearly as when i first stuck my head in teh system and pissed all the ppl waiting in line to play the game...thankfully back then no one wanted to ruin a 7 year olds fun. the system was a upsidedown tv that was facing a concave mirror which then projected the image above off teh glass top....thats basicaly it you may need to create a half black dome on the top too to get the best effect but it should work. my idea is to buy one of those hologram dome mirrors shadow box toys that you put a figure in and it creates an illusion on the hole in the top. cut it in half then use a ipod touch facing the half mirror and make sure no outside light is showing between the ipod and the mirror. next you'll need black duct tape and cardboard and glass top to form the box and dome. have a movie playing on the ipod and that should do it .. I havent tried it (lack of money to spend on one of those toys ...nor can i find one) but im almost 100% sure it would work. if you knowhow to make or find another concave mirrors best to experiment to find out which will work the best. try that out it should basicaly make a minni version of that classic aracade illusion so many years ago
i typed alot in previous message but i don't know i think i used the wrong comment button so i am going to put it short i studied holograms my entire lifes a projector and glass isn't gonna cut it to get even the slightest bit of a 3d hologram you need a resinating laser beam and it has to be cut in 2 by a special glass reflected off 2 mirrors and one needs to be focused into a object and the other needs to keep going then both beams need to be redirected using mirrors and 2 more glass lenses like magnifying glass to refocuos the beems intensifying them so when the recombine they slam into eachother like 2 cars moving at high speed when this happens the object or what you put before the second beam gets turned into a holographic image because with the beams hitting one another they support each other an stabalize i am planning to start a company once i recieve and inherritance i just been granted but i also have to use some of it to do some charity work its a personal belief and something i need to do email me if your interested in learning more i'd be willing to teach you what i know only if we work out an agreement because even though i been doing the work i can no longer work twards building my prototypes because i was borne with pour bone structure and due to it i am now in permminenant medical care center on life support which is another reason why i need someone to work as my right hand man as i am now on my own i have my familly but they don't know annything about electronics or science i need someone who is willing to follow what i say and who i can trust

Okay everyone, I updated this topic so that it doesn't sound so..........demanding. Again, I apologize if the previous topic information upset anyone. I think a projector/glass method would work well, but I haven't tried it yet :).

Again....my apologies. I will remember to ask questions instead of posting a statement from now on. I appreciate the advice.
(I guess that's addressed to me - it's easier to tell if you click the "reply" button in the corner of the post.)

Sry. I just joined 2 days ago....
In that case - welcome!

Just browse around, you'll get used to us.

Thx. I haven't posted any -ibles yet... Just getting help for the big projects
As Goodhar said, no need to rush in. Remember to take lots of pictures of what you do, use macro if you need to, and, for goodness' sake, make sure they are in focus.

If you need any help, don't be afraid to ask.

On wikipedia, at some institute, they develpoed a substance that when two beams of light intersect in it, the point of intersection is brighter than the beam. This could possibly work, but God only knows where to get the stuff.. I did learn that by splitting a film hologram in two, you get two of the same image (but that isn't 3D)... Maybe if one was to get six individual 2D holograms (square) of the same object (top view, bottom, left, right, front, back) and glue them together, that might work... But the object in the hologram would have to be in the right place in the slide. I'll look into it.

This sounds like you are telling us to do your homework for you.

That's not a good approach.

A better approach would be to do some research yourself, using the keywords you have included in the text, worked out a way of generating a floating image yourself, done it (taking lots of photos as you do) and then writing up an Instructable to show and tell your achievements.

Maybe you could ask for help on specific technical points as you go.

(By the way, if you are willing to use PoV, then it's not a hologram, it is an image.)

I guess you could take an RGB LED grid and have it ocsillate up/down, left/right, etc.. But god only knows how they program a strip or what's more-a grid of LEDs to make a 3D object. I saw a method of using a piece of glass at an angle to a picture above/below it...(that sounds kind of easy..) but still, the phenomenon only occurs when the observer is right in front of it. The problem with LED cubes (although they work) is that the LEDs that aren't on obstruct the view of the image... If the LEDs could completely become invisible when they're off, you still have the wire grid in the way. I like the POV idea the most...

Good idea. My apologies.
You will write up an ible, right? :-)

I'm new here. Instrucables posted: zero. But, I could if I get a good idea! But right now, everything I can think of.....I can only design... If I can think of something easy, quick, works, and is simply awesome, I will post it, and you will be the first to know.
Tis ok, no rush. It took me nearly a full year to find the time to get around to my first -ible

Why should we do your research for you? Especially when you tell us what to do instead of asking.

Start with Wikipedia, then go to Google. If you really want technical articles, try Google Scholar. If you don't like doing online research, try a local college or university library, where you can get access to journal articles.
