Interactive Multitouch Display

Step 2 Screen frame

The primary component to be constructed is the screen itself. This is a piece of acrylic, with a frame which holds the diffuser and IR leds in position. I opted for a sandwich style construction out of 1x2s and aluminum channel. My acrylic was 30x36x0.25 inches so I made two frames to match, mitering the edges and assembling with screws and construction adhesive. The sandwich design is simple and leaves plenty of room for wiring the leds.

Where did you purchase your acrylic?

eBay is a good source if you don't mind paying a few dollars shipping.
