Topic: other options for rgb addressable strip? (Read 1 time) previous topic - next topic

these are the type I am looking for but was wondering if there was any other options?  I do like having the 7bit color per channel and this seems to be one of the few options that offer this. 

basically I will have a 1 meter strip, along with two 3w rgb led's. with the goal being ambiant light and music sync(color organ).

ouch, well it looks like the ones I linked will be the best bang for my buck.  Seems like they are well documented and shouldn't take too much effort to setup.

only other question I had is if this would be enough power to run two of these these, plus the already mentioned led strip.

from what I can tell the m of led's will draw 1.8 amps, and the high power ones will draw 1.2 amps.
so at 3 amps I feel I should be safe?

For the high power LED you need a constant-current source (for sale on ebay). You don't just power it from a 5V source with a resistor in series, like you do with a 20mA LED.

drats, from what I understood the LPD8806 on that rpg strip handled the current.  As for the two high power led's I am just planning on running them on a logic level mosfet until I get a constant current driver. 

Chagrin

I don't see where you linked to the LPD8806 strip. But yes, most do handle the current on their own. It's only with high power LEDs (like the 3W LED you have linked) that it becomes impractical to use current limiting resistors.

In general though, I think rpg strips are too dangerous to deal with.

first I have heard of rgb strips being dangerous.  Is there something I should watch out for?

FYI he put RPG not RBG  it was a joke on a typo

GO TECH!

wow...din't even notice the typo. haha
