Hi, I have just finished making my new Tune in sign for my new display. After other years of people not really seeing the Tune in sign I decided to make it a little bigger (hopefully people might catch on a bit quicker this year). This sign is quick and easy to make and only uses 3 RGB channels. I ordered some letter stickers from ebay and bought four of the cheap no structural pine battens from Bunnings, some left over corro flute, and some RGB 12V strip, I used a bit of ply for the backing but corro flute could be used. I will be using two star pickets to hold the sign up. The stickers are placed in position on white corro flute and then the whole area is spray painted black. Once the paint is dry just peel back the stickers and your done.
