I made it at TechShop.
Step 1: Set up image and run the laser
I etch using 1/4 inch Acrylic sheet from Tap Plastics.
Step 2: Etching is clean. Check for defects.
Step 3: Create Wooden LightBox with LED
I use RGB 5050 LED strip non weather proof. Solder a 9 Volt battery connector (Radio Shack) to one of the colors (R, G or B) to the anode and the positive terminal to 12 V positive tab. Push the LED strip through the through hole in the bottom and lay the LED strip in slot in wooden block.
Connect a 9V battery and lights are on.
Battery fits snug into battery hole compartment. But just in case it slides out;Wrap a rubber band around battery for a tighter fit.
Step 4: Happy Christmas Faces from the Glowing Nameplates
Give them a second to guess what they just got. Some think they got a lightsaber of some sort. Others thought it was a puzzle.
Now pass out the personalized acrylic nameplates.
Smiles all around.
Note: The nameplates seem to stay lit for more than a week on the one battery. Most people disconnect them after the party though.
