I finally got around to the tune to sign today. Printed on the inside, and illuminated by as set of fifty 2801 pixels in a 5050 format. Then I needed to mount the pixels about 7cm behind the sign, so I mounted a second sheet of coro behind the first, with a 7cm gap. Finally the result (This was actually before the sides were painted, so thats why there is light shining out the sides) and The images show the sign as a little blurry, but in reality it is not. There is slight light bleeding due to the coro, and it is made worse by the slow shutter speed on the camera to take the image. A bit of tidying up to do, corner moulding to glue on, but overall it worked well.
