[Noisebridge-discuss] Basic question about electricity.

[Sean Cusack]

Given that there is no datasheet provided with the Makerbot RGB LED strips,
you won't have any real answer for sure...BUT!

If these are anything like the sparkfun LED strips:
http://www.sparkfun.com/products/10259, then you'll need 60mA per 3 LEDs.
There are 60 LEDs on the strip, so you'll need 1200mA per strip. Times 5
strips? You'll need a grand total of 6000mA @ 12V to power all 5 at once.
>From the thingm website (http://thingm.com/products/blinkm-maxm.html), the
MaxM is rated to: 5V-24V, 3A max. So...prolly not :(. You might get lucky
if they measured the 3A at the 24V power input rating, so you could be able
to get 6A at 12V without blowing it up...but I would say that's probably
dubious. At the very least, you'll need to heatsink the hell out of it and
run it in a cold room...its probably smarter to just get more than 1
controller.

Its tough to know if this math is correct though given that there isn't a
datasheet on the Makerbot strips though :)
