Here are some pics of the DBU Apple I made.
It was made from a clear plastic container that held crazy glue. I used a dremel to cut it down to size and cut slits for the LEDs. I taped off squares over the IR receivers, then gave it a couple coats of paint.
I then added 2 baffles made from plastic card for the top and bottom, and 2 made from card stock for the interior baffles (I should have used thin plastic but I had none) with spacers inbetween. All were painted before assembly.
Now I just have to connect it to the DBC and pray that it works.
