How To Build a LED-LP Multitouch Table

Here we look at building a LED Light Plane (LED-LP) multitouch setup using an infrared light source to light up fingers/objects placed on the surface and a camera to track the blobs.

Hi,

What is the name of the metal mounting piece you use to support the LED's in this video?

Thanks

[PeauProductions]

@xavierokeil That is some aluminum channel we found at our local hardware store. A common piece of metal to use is the metal rails used for a sliding glass shower door.

Nice tutorial. Explains a lot. Thanks.

@UlfilasUk Yes there are many LED calculators available on the net (I link to two of them on my blog). Feel free to jump into a live chat on my store or send me an email if you want to discuss more specifics.

@PeauProductions I was thinking of using the LEDs actually - do you have a simple wiring diagram?

I've been chatting to Gabriel who did the Nivea wall and he's recommended you btw :)

@UlfilasUk Just treat the lasers like LEDs when wiring them up. I typically wire them up in parallel with the laser power adapters I sell on the store. Or you can also use a modified computer power supply off one of the 3.3 or 5 volt rails.

Any Advice on how to wire those bad boys up?

Good stuff Nolan ... I'm a fan :)
