Light Art Innards

This is the "back end" for one of my LED art pieces. Stripboard makes it fun and easy! Click the image for the wicked large version. Those are color-changing RGB LEDs, which run nicely off 3V (without a resistor!) I got the barrel jack connector, along with a nicely matching 9VDC regulated power adapter from SparkFun. Simple, no?

they look great - really like them

i see a connector for a battery - how long would the lights last for if they ran of a battery?

cheers :)

Thanks :)

This one runs for at least a good 20 hours on an alkaline 9V before the blue color starts to flicker and fade. I actually think it's interesting how the image degrades as the voltage drops.

I'd love to make this... have only found two suppliers for the auto change color LED's so far... one from China and one in the US....

Could you let me know where you picked up the strip board and connectors? I searched on Spark Fun and couldn't find them....

I am also interested in making one of these for a friend of mine, as a Christmas gift. Is there any way you could share with me the directions for making such a piece of art? Thanks. My email address is if you could spare the instructions. Thanks so much.
