well, i can't say "this is what i'm going to do" as then a lot of people will run out and get the same things, then find out it doesn't work for us...
but...
what i'm trying to do is work on getting smart string guts (like i did with last years smart arches) to power a 3W rgbled.
that way i can get a 3watt burst of white, but also be able to use it in rgb color pops of 1watt per color.
i can't directly hook up the led to the TM1804 since the current is way over what the IC can handle, but i have one way it will work, and working on another way it might work a little better (less parts)
i can't do a whole string of 128 like the smart string nodes, but i should be able to get a few on the string. maybe about 3 (considering the amount of current going through these...)
Dependiong on how i power them, i might be able to get away with a few more, but then that would change how they're controlled. (but still might be doable)
