Step 2: The Display
The display is made up of a sandwich of the display Board, The square reflector, a diffuser and a smoked perspex window. You can place a sheet of tinfoil under the LED's to give more reflection, just make sure you cut a hole in tinfoil around a legs of each LED so it doesn't short things out. I also sanded the lens of each led to distribute the light more.
The first three photos show the strip board version, the remainder the etched PCB version.
