Step 6Build the Tray to hold the LEDs
The LEDs and circuit board must be rigidly attached to something, and that's where the tray comes in.
You can make the tray any size you want (as long as it's bigger then the minimum size you're boards can fit in). Mine is 46x31 inches
I decided to use a 1/8in peice of MDF in a tray of 1x3 pine. 1/2 inch from the bottom of the 1x3's we made a 1/8 diameter groove to slide the MDF in.
Originally, i wanted to have the ends connected via tongue and groove notches and glue, but, we didn't have the correct tools (even though we tried our best to make them), so i just opted to screw the ends together, it works just the same, and looks just as good (most people will be looking at the top anyway!)
