In preparation for a new project we've been putting together a multi touch table along the lines of the design pioneered by Jeff Han.

More details will follow including some software releases but for the moment, here some images of construction.


Building the basic frame in the back garden at home.
Wiring up the 140 IR LEDs in the lab, assistance by Rob (visiting Nuffield student) not to mention Bill down in the labs, "you can have your current limiting power supply back now....."
The final product.
"I told you the exterior plywood would look fine with a coat of wax."

Personally, I like the aluminum edging.

Just incase you don't believe its producing enough IR light, here's what an IR camera sees. This is without the tabletop, hence the flood of light around the perimeter.
