I went to home depot and picked out some wood that would be good enough for the inside framing of the table. I tried to get something light weight and sturdy. The main reasons for the frame is to keep the table sturdy and also make it so the walls of the table will be square, flush, and have something to screw into. I measured out all the pieces in google sketchup and then had someone at home depot cut the pieces to size.
Wiring the LEDs for FTIR
I contemplated making my own PCB boards for the LEDs, but after doing some searching I found some boards online that would be more cost effective and work better than making my own boards. I decided to buy the following board from futurlec.com It’s possible to get 4 individual strips from each board for making individual LED PCBs. I needed a total of 10 strips for the two sides of my acrylic so I purchased 3 boards for $9.50. The strips are good because they will allow for 4-8 LEDs per strip. I chose to do 5 LEDs with a 1ohm resistor per strip (@ 7.5v), making a total of 25 LEDs per side of my acrylic.

Projection Screen tests…
I took some pictures of the projector projecting on 3 different types of materials. I’m using a Casio XJ-S30 Projector which has 2000 lumens and 1800:1 contrast.
The following images consist of Rosco Grey Projection Screen (left), tracing paper (middle), and Rosco Black Projection Screen (right).

New video! The table is (almost) completed!
New video showcasing the final table at work. The software is all a work in progress and new releases will be coming soon of all applications as well as new ones. If you like the video, please pass it on. If you don’t like the video, please pass it on anyway. Enjoy!
