Your friends will be amazed to see their names in light.
The author wishes to fully credit the folks over at Evil Mad Scientist for inspiration.
Their instructions are totally awesome, and I hope you will consider getting your supplies there as well.
I added two improvements to their Christmas Edge Lit cards which serve to take the original idea beyond "card" status. My main goal in making these improvements was to make the display stand (or hang) on its own, rather than being inserted into a card.
While you can make just one, the time required to gather all the materials, and costs is better suited to a dozen or so. In this way, each individual display will cost less than a dollar, and be completed in less than half an hour.
For all your work, you get to watch your friends faces light up. Priceless.
Step 1: Gather Supplies Part 1- Electronic Throwies
Be sure to check the comments at Evil Mad Scientists for purchasing possibilities
I bought mine from Buy LEDs Online
because they allowed me to select any quantity of colors (I prefer diffuse) and the battery prices were excellent.
Red is my favorite, and whatever you don't use at Christmas can be used for Valentine Day.
Buy one LED (10mm) and one battery (Type 2032) for each card you intend to make.
Of course you should allow a little play time when the package arrives. It's absolutely stunning how the LED and battery fit together to make such a bright light in such a small package.
Step 2: Gather Supplies Part 2- Plexiglass aka Acrylic Sheet Plastic
You will also need electrical tape (festive color optional), exacto knife, ruler, and straight edge in later steps.
