How to make an edgelit LED sign on the XCarve CNC from Inventables. You can use this technique for any edgelit sign, of course. Make sure to adjust the files based on the exact size of the wood and acrylic you are using.
See http://www.inventables.com for more information about the XCarve CNC machine. Inventables has supplied this machine to me at no cost in exchange for a few video project tutorials like this one.
