You´re welcome! Another cool thing about those 4 pin rgb leds is that you can program your very own animations, and i hope you´ll succeed :)
Hello :)As i said, i have found some with only two leads. It seems like they are fairly uncommon, i found mine in some cheap color changing solar garden lights. You can use normal rgb leds, but make shure nothing shorts out and the wires don´t show through the stem. I´d recommend you to build a standalone arduino board, if this doesn´t exceed your skill level. This is very easy to do, and there are many tutorials on youtube about this subject. You only need a 16 Mhz Crystal, an Atmega 328P Chip, two 22 pF ceramic disk capacitors, an LM 7805 and a 10 kOhm resistor. Keep in mind, that you will need an Arduino or some sort of Ftdi breakout board to program it,but again, there are many tutorials on this subject on youtube.Greetings from Germany :)
This was fairly simple: I had some rgb LEDs laying around, wich had an integrated rgb controller, thus having only two leads for power :)

Nice project! I am currently building something very similar (Instructable coming after the Instructable for my Boombox), and congrats for your award.
Awesome! Very nice explanation! I'm definitifly going to build this. (Already prototyped it - works flawlessly) Since the Lm 324N is a quad op amp, i'm going to make it stereo with a single powerful led each (red & green) and im going to use it with my homemade boombox (instructable coming soon!), wich also features built in VU-meters.
