I will mail a UV LED dipped into GITD paint to the first five people who correctly identify the music in the video! Send me a private message if you know.
General Info on GITD:
Step 1: Lets Build It!

The first thing to do is to make the GITD LED's. I bent the (+) lead (the longer one) into a little loop so I could hang it to drip dry after dipping. Next time I think I would use masking tape and rig up something that I could stick the LED to so it can drip and dry. The way I did it, they tend to swing around and can stick to each other if they get to close. Give them about 24 hours to fully dry. While they are drying lets build the circuit.
Step 2: The Circuit
Step 3: Powering It Up and Use:
Take two CR2032 cells and put them on top of each other to make one 6-Volt cell. Yes, it kinda sucks to have to use two, but as I write this my prototype has been running for 48 hours straight. And form deal extreme they are pretty inexpensive. Great for throwies too! Using the electrical tape wrap the (+) and (-) leads to the appropriate terminals of the battery and tape it all together just like a throwie. In fact, you just made an LED glowie!
These are great for kids and hiding around the house in closets. They also look cool at night. I am going to build a bunch to use for outdoor decorations.
Step 4: Taking It Further
As I already had the GITD paint and it is rather expensive I began to search for less expensive alternatives. And, I know there are a lot of other very cool things that I could do with these LED's. If you put a bunch in a row and scanned them you would have a very cool and organic looking Larson Scanner without having to pwm the levels. I ordered enough to build an Matrix of them that should show some interesting patterns. I will write that up when I get the parts and build it. I also ordered 4 oz of Zinc Sulfide based GITD powder from the link below. I am going to experiment with making my own GITD paint to dip the LED's in. Just coating the LED with clear nail polish and dipping it into the powder worked pretty good.
have fun blinking and glowing.
If you were wondering what I had the Economy Green GITD paint from it was this: And, the price has gone up!
