RGB LED Flexi-strips

by mvsopen on Mon Sep 20, 2010 3:24 pm

I just watched last Saturday's chat, and I'm highly interested in the spool of RGB LED's, sold by the meter. I can easily think of a dozen different projects that can use something like this.

But I'm a newbie at Arduino stuff. I understand how to control PWM, but I'm a little fuzzy on interfacing this strip. Lada Ada said that it works like her "Bedazzler" product. I've found the schematic for that: http://ladyada.net/make/bedazzler/download.html

To make it work for the RGB string, should we just omit three of the MOSFETS?

I see from the announcement post, in the comments (linked below), you mention that a 5m reel takes 3 amps (600mA per meter).

Where can I get a good 12V 3A power supply?

Okay here's one for about $7.50 shipped, turns out one of the Eee PCs is also 36 Watts (crazy that some LEDs use the same power as a small laptop). It's sort of sketchy-cheap, so we're ignoring the word "good" from my original request, so I hope it doesn't catch fire. I'll let you know if it works well when it arrives.
