Custom Back-lit Sign

I bought a custom 'broken glass' sign at a farmers market, a couple of summers ago. The sign was created using an old window frame, and was comprised of colored broken glass, and glass beads. All this glass was glued, in some manner, to the window. The sign was backed with a clear plastic sheet, which was stapled down.

This is an awesome sign. I mean whats not to like? Could you guess that I'm from Idaho? Anyway, i also thought it would look really nice with some back-lighting.

I completed the following steps:
1. Acquired the LED strip, and cut and soldered the needed lengths to create the "IDAHO" out of lights.

2. I used 1/2 quarter rounds cut to needed lengths for the border LEDs.

3. Wired both sections together, and connected to the female DC connector.

4. 3 layer cloth LED light spreader, designed by my wife, tacked in place.

5. The letters were whip-stitched into place by my wife.

6. Final Wiring - using gorilla tape to hold everything in place. Wiring to allow for edge lighting as well as the letter based lighting.

7. Testing with 12V 5A DC power adapter.

I liked everything at this point, but didn't like the fact that i had to plug it in or unplug it to make it all work. So i ordered a capacitive sensor, and used a 2x 5v relay switch I had on hand to create a circuit to allow for this

Final Comments, and video of it being turned on and off in it's 'hung' location.
