This is a very interesting project. I have several damaged EXIT signs I can experiment with, they have many LEDs on a large PCB board. I will keep you posted.Thanks for the great ideaPhil
This really a cool idea. I don't have kids at home any more but i have a grandson that may like it. If he does i will surely make one. Thanks for the great idea
WOW!My two hobbies are photography and mini computers. This is a fantastic twist blending the two together with great mind bending results. I will try to recreate this project or take ideas from it for a similar effect.Thanks Phil
Thank you. My father would be happy to see it up and running again.
