- VSKBadCRC, on 10/12/2007, -1/+82We're being given instructions to build a device from the 24th century from a website that looks like it was made in 1993.
- dbxz, on 10/12/2007, -1/+47you forgot to put the time crystals in... ;)
- Lurk3r, on 10/12/2007, -14/+55WANTED: Somebody to go back in time with me. This is not a joke. You'll get paid after we get back. Must bring your own weapons. Safety not guaranteed. I have only done this once before.
- loqqq, on 10/12/2007, -0/+37I got one of these on Ebay, but it didn't work.
- affanjam, on 10/12/2007, -1/+37If you wanna see the video of it working

its cool but it sounds loud - ahawks, on 10/12/2007, -10/+43Woah! I just found a pretty crazy bug in the digg comment system.
When voting up a comment, click the thumbs up over and over really fast... you can get in like 8 votes before it locks/grays out the button.
Edit: It looks like it's temporary though... as all the ones I tested on are now back to just +1 - Sagags, on 10/12/2007, -2/+32Seems cool but the page is somewhat hard to understand.
Also dosnt seem like something the average joe could do - xorian, on 10/12/2007, -7/+35The author of that page clearly doesn't know much about webdesign :p
- griz, on 10/12/2007, -1/+23Ok, this is nothing more than a persistence of vision project whereby the image is projected onto a flat surface. The flat surface moves up and down via the piston motion and makes the image appear 3D.
Scale this up to the size of a room and stand on the projection surface and you will enjoy being smashed against the ceiling many times per second. - OcarianPhoenix, on 10/12/2007, -2/+18This is not what I understand as a Holodeck, this is: http://en.wikipedia.org/wiki/Holodeck
Holodeck IS NOT A 3d display... 3D displays are one thing and holodeck is completely different... You can read how a holodeck (the one seen on Star Trek) works on that wikipedia article above... - slacknerd, on 10/12/2007, -5/+19Needs more cowbell....
- griz, on 10/12/2007, -2/+11Actually the title says "Build a Holodeck" Can't get any more of an inaccurate claim than that.
- LucasVB, on 10/12/2007, -0/+9Ahh, many thanks for that vid!
To be honest, he just expanded the POV-display design to a third, controlled and orthogonal dimension, but in a very brute way. The concept works, but it is very limited to the approach he used with a big piston moving up and down. Try to scale that.
The rotating pixel matrix someone dugg a few months ago gives us a CYLINDRICAL space, but it is far more efficient and less noisy than this. The problem is you're limited with a circular arrangement of pixels in the Y axis, which is what this guy tried to avoid.
If I were to give an approach to his idea, I'd have made got a thin semi-transparent white net and placed it on a track system connected to gears and a electrical motor. The laser would point at the intersections in the fiber of this net to create a pixel.
The pros of that would be less noise and the fact it is a net gives us little air resistance, so we save energy. I think it'd look a lot better and less bulky too.
But still, it's amazing how he managed to build and plan this all by himself. Kudos to the guy! - Cyberdactyl, on 10/12/2007, -2/+11I have no problem with the site. He wants to share his insights, and most likely could care less about making the pages look pretty for those surfing, looking for pretty Flash pages.
- neoknight, on 10/12/2007, -0/+7@VSKBadCRC
it was optimized for digg! - MOJIRA, on 05/17/2008, -0/+6Where's Wil Wheaton - he's on digg right? Let's ask him if it works.
- zcreem, on 10/12/2007, -1/+6OMG stop the world I want to get off!
This is too bizarre, the site, the motor cycle piston generator with warp control utilizing a cork.
Beam me up Scotty, please. - JJP0223, on 10/12/2007, -4/+9@ Improfane - What are you talking about? What is worse then this? There is some non-styled text, some pictures just thrown in between paragraphs, and a lot of bold text. xorian is 100% right on this one.
- meekar, on 10/12/2007, -4/+8I think the content makes up for the web design on this one.
- dikjr78, on 10/12/2007, -2/+6Looks cool, but they need to work on the web page a little.
- inactive, on 10/12/2007, -2/+5rtfa please. No 3d glasses, which the sega requires. Also laser disks just suck.
- brbubba, on 10/12/2007, -1/+4You're absolutely right, this has been around for years. What do you think those twirly things are are that write out messages in a circle. It becomes very apparent when watching the video that the image isn't actually being projected into thin air, but onto the head of the moving piston. This is far from a 3-D effect, in addition actually producing true 3-D images using a piston would be almost impossible, if not highly impractical. Also this precludes any possibility of having interaction with the image much less passing your hand through it.
- PaulRay, on 10/12/2007, -1/+4"Also this precludes any possibility of having interaction with the image much less passing your hand through it."
Ummm... Passing your bloody stump "through it"?
I have to agree... This isn't too impressive and not even in the neighborhood of a Holodeck. Even a fake, projected neighborhood. - diggeridude, on 10/12/2007, -0/+3Is this new news? The first page says (c) 2003 and the second says 2004.
- Fratz, on 10/12/2007, -0/+3I really have to admire the guy for coming up with this from design to implementation, but I'd be amazed if he isn't limited by his fundamental design. It seems that making it rely on large mechanical motion and controlled lighting conditions are both at odds with further refinement, robustness, and widespread usability.
- TailGunner, on 10/12/2007, -0/+2@Lurk3r: Push it to the limit!
Anyway, personally I think we're gonna need some kind of light-saber type technology (not the slicing part, but the part about cutting off the beam) before holograms become a reality. For now, it's just kind of mediocre immitations. - danep, on 10/12/2007, -15/+17Umm... yeah. Buried because it in no way resembles a holodeck or anything in Minority Report. 3D "displays" like this have been around for a while.
- jgtg32a, on 10/12/2007, -3/+5Maybe he was going for efficiency, granted the font sucked but other than that I didn't mind it
- cbiz, on 10/12/2007, -0/+2I thought the various fans in my pc were a bit loud.
- stolenpass, on 10/12/2007, -6/+8This project is not CLAIMING to be anything out of Star Trek or Minority report. It is a proof of concept. The designer had an idea to create his project out of "junk" he could find. The design of the system is simple and the purpose of the system is to create a Holographic object WITHOUT the use of 3D glass.
It does what the designer set out to do. - TheBarge, on 10/12/2007, -0/+1How hard would it have been for him to just use some off-the-shelf open source CMS? That would at least make it LOOK better.
- Iandefor, on 10/12/2007, -0/+1Can I get a link (or the name of this projection method)? I wasn't aware of this kind of projection prior to seeing this.
Thanks. - lolage, on 10/12/2007, -0/+1Thats what I was just about to comment on. I know its only a little project but man, I bet he was disappointed with the noise. "My ears. They bleed. Oh no, the time warp.". Good work nonetheless.
- QuimZ, on 10/12/2007, -0/+1Then the person who submitted this needs to revise his overview.
"A cool computer 3D digital display and interface ala Minority Report"
Pfffffffffffffffff't! - porkstacker, on 10/12/2007, -0/+1Nice theory but I’d like to see why he abandoned the project sometime in 2004 (I assume this, as that date was the last time the page had been updated).
- KJSatz, on 10/12/2007, -0/+1Ala? Allah, à la...but ala?
- digboy99, on 10/12/2007, -0/+1This guy thought that he could make a buck here in order to fund his massive Hello Kitty museam. Unfortunately, his time-machine rental was due back his local home depot, and so he had to return back to the 24th century to avoid the nasty late charges. Apparently, these "holodecks" are all the rage in the 24th century, with Wal-Mart cranking these things out like mad (using slave labor from the Crab nebula).
- silicondon, on 10/12/2007, -0/+1While I respect this guy for building it on his own, I'm a little more excited about the stuff 3dh is doing. A guy I work with went to see a technical demo from them last week and couldn't stop raving about how real it seemed. http://www.3dh.net/pictures.htm
- Jadix, on 10/12/2007, -0/+1impressive. the epitimy of a bored, good-willed, hacker.
@griz: You could use this for a huge suface by just having a piece of plastic between you and the giant piston. - RedHairedMan, on 10/12/2007, -0/+1Heh, there's something interesting about a high tech concept being constructed out of spare, low tech parts in some guy's garage. I love garage science. :)
- 01101010, on 10/12/2007, -2/+2no 3d glasses needed. it was an arcade console, with the image (hologram?) displayed on the surface in front of the player.
- inactive, on 10/12/2007, -2/+2Yeah, I'd like to see them try to make a sphere.
- Daiden, on 10/12/2007, -0/+0The title is misleading, but this is still very cool. At first I laughed when I saw the cork, but still, for a home-made project done entirely by him, this is very impressive.
- JrGhoull, on 10/12/2007, -0/+0silicondon-i would have to see something like that personally to believe it.
cute little project (happy i read all the comments on digg before hand)
one little trick to knowin when a project is fake, or not what it claims to be...the person (such as this guy did) will not show his face. - blincoln, on 10/12/2007, -0/+0Actually, you're only partially correct.
It is a persistence of vision system, and it does involve a moving part, but the image is *NOT* projected right onto that moving part.
If you've seen one of these:
http://www.optigone.com/holograms/mirage4.html
It's using something similar to that effect to make the image appear as if it's in the air some distance above the lens.
If you were very concerned about safety in a bigger version, I don't see why you couldn't put a sheet of reflective material between the lens and the viewing area, and enclose the other five sides of the moving part section in a box. - digboy99, on 10/12/2007, -0/+0His time-machine rental was due back to the home depot, and so he had to return back to the 24th century, where this sort of "holodeck" is common.
- SuckMyDigg, on 10/12/2007, -6/+5I'll go back in time with you if you don't try to make out with me.
- nufoto, on 10/12/2007, -2/+1Cool! Looks like a 3d version of Mechanical TV!..They need a better Camera though! Very creative!
Thanks for the Video! - BooostedAWD, on 10/12/2007, -4/+3I'd rather just have a holopatio.
- daguy33, on 10/12/2007, -2/+0Weren't holodecks from starwars originally?
