Schproket is made out of 2 sheets of medium grade 3/4" plywood and 2 2"x4"s.
I added 3" in depth for where the LEDs will be placed along the long edges (now 30"x27"). Then I added 4" in depth to one side to make room for the projector. This prevents the projector from getting in the way of the projection. So my final dimensions are 30"L x 31"D x 35"H.
Schproket is built like a box, so all the sides are solid. I left one side open for access to the inside of the box, which you will need. I won't get into carpentry here but you will need some power tools and basic carpentry skills to make a box.
Things to remember:
The acrylic has to rest on something. Make a lip for the acrylic to sit on. I cut the support 2x4s 1.25" shorter than the full height, then placed a 3/4" piece of plywood on top of the supports stretching across the back and the front of the box. Then placed the acrylic on top of that so my acrylic will sit flush with the top of the walls of the box. The frame to hold the LEDs will also sit on this lip.
Here is the Schproket box after construction with the acrylic on top. The acrylic still has its protective paper cover on it.
A good thing to add to any larger interface is caster wheels. Especially with plywood these things can get heavy.
