Video Extender: Extends Different Types Of Video Signals Over Long Distance
Long distance extension of video signals is possible via a Video Extender, dvi extender. Also known as VGA Boosters, signal boosters or VGA baluns, these devices comprise of a transmitter and a receiver and connections between the two are secured using category cables. While the former connects to the video source, the latter is connected to the extended display. Both these units are designed to ensure a rapid signal delivery. These Cat5 cables used eliminate the need for bulky VGA cables and are cost efficient as well. Designed to deliver uncompromised video quality, these extension units provide crisp and sharp images with a resolution up to 1900×1200.
Available in various types, the most common model is the VGA Extender. Easy installation and plug and play functionality make these units a popular medium of video extension over distances up to 590 feet. Optional stereo audio, infra red remote control and RS232 control is available in some models of these devices which are available in 2, 4 , 8 or 16 ports. Compatible with most operating systems this extender supports many video sources with a VGA connection, including PCs, DVD players, VHS, DVRs and so on. In order to increase the distance of use, this product also comes in a wireless format. Equipped with session security log-in and Wi-Fi WEP protection, these devices allow any desktop or notebook computers with Wi-Fi to access the VGA monitor or projector. Another commonly used extender is the Composite Extender.
It allows composite video signal transmission up to 1000 feet. Available in a point to point version as well as in 2 and 4 ports, this device has the ability to send a single composite video source to as many as four different locations with no loss of composite video signal quality. The repeater/receiver version of this extender allows looping the video feed overcoming the 1000ft distance barrier. Many versions of this model can be mixed and matched together in order to have unlimited flexibility in configurations. Some options include digital and/or stereo audio connections. All these features make this device a popular choice in situations where the video inputs need to be sent to multiple remote output devices. The Video Extender also finds its usage in military, commercial, industrial, financial, medical arenas and in schools, airports, restaurants, banks and shopping malls.

Yup, infrared light + acrylic + semi-iffy projector + no real compliant surface = beta done! Apps in order: 1. CCV Tracker (Track light blobs to send to port 3333 in programs as input 2. TUIOsmoke (that previous program. But now cooler) 3. PyMT (Python’s attempt at multi-touch. I’m actually not a huge fan. Oh well) 4. NASA World Wind (SWEET! When it’s all smoothed out with the tracking, that is…) 5. Surface Photos (Not within the Surface Shell, simply because my laptop can’t handle that mad stuff.) LAPTOP specs: -1.8ghz dual core amd athlon x2 -Nvidia GeForce graphics card (Not newest, but not bad…256mb I believe?) -2GB RAM -Windows Vista Home Premium Still need: -Compliant surface (to eliminate the need to wet my fingers before touching the surface) -To create a program that can incorporate input from port 3333… -To make the actual box…doh! What is this one made out of? -3 cardboard boxes folded flat for 3 sides -1 posterboard cut to the size of the 4th side -Wonderwall Projector (cheap, yes. Effective for a demo? Also yes.) -PS3 Eye (This one has the IR filter removed and a bandpass filter in place) (ok, so it’s a poor-man’s filter. Sue me.) (Film negatives work fairly well!) -Miniature mirror for the webcam and projector to point at so it’s not backwards on the surface -S-video cable from my Laptop to the projector -18×24″ piece of 1/4″ thick acrylic -2 rows of LED’s on Microchip containers fitted on opposite sides (you can see one of them in this video …

@Dominoes282 There is actually an entire forum filled with this concept and people much more knowledgable than me. Do a google search for NUIgroup and you’ll see what I mean!
But yes, I’m doing my senior project on this for my school, so there will definitely be a much higher quality review/breakdown/demo when all is said and done. It will probably be VERY long, but VERY in-depth!

@NateTheGreat555 So your saying that I get a cheap LCD screen I would save money on getting a plexiglass surface and projector right? Only problem is that I would have to put the LEDs somewhere else, maybe… Also that would cause a problem for the PS3 eye cam because it would be harder to position. It’d be awesome if you made an instructables on that

@Dominoes282 Frankly, that projector is crap overall. I’d suggest looking into using a plain old LCD screen that is lit within the box. But I understand your problem. Mine was a Wonderwall box, but was from the Sharper Image. It leads me to suspect that there is really only one projector. But that’s just me.
For this design, I actually used only 22 LEDs spanning across two of the longer sides. That’s not conducive for this surface overall, but was enough to get the concept across.
Good luck!

Also, how many IR LEDs and where did you get them, thanks!!!

Please help! I found two wonderwall projectors and I need the right one! One was a sharper image and the other was a discovery!

@chrishajduk84 That’s totally possible too! That’s called diffused surface illumination, I believe, and is actually very easy to make as it doesn’t really use Near-Infrared light (I’ve come a long way from RB customs…not that there’s anything against that, of course!)
I’d be glad to help out if you need it, it’s extremely slick when it’s all said and done with!

That’s pretty sick. Wish I could have that on my desk with the projector + ps3 eye mounted on my ceiling. That would be pretty sick…
I might decide to do this in the future. (and if I do, I know who to ask for instructions)
