Hi Blinkinlabs! I've got a question about the maximum current that the BlinkyTape is designed handle for sustained periods.
I noticed this line of code in your ColorSwirl sketch:
LEDS.setBrightness(93); // Limit max current draw to 1A
With the brightness set to "93", the ColorSwirl's default animation draws around 250mA (a quarter Amp). Changing the "93" to "255" in that sketch bumps the power draw up to 675-725mA.
With all pixels set to full-on white, and brightness set to the maximum of "255", the BlinkyTape draws 1.5+ Amps.
My question is this: what's the maximum current that the BlinkyTape is designed for handle for sustained periods? Is the "1A" comment in the code there more to preserve battery life, or is there an element of the BlinkyTape's electrical design that makes it a bad idea to run at more than one Amp for more than a short period?
Maybe to rephrase my question a bit: does the "+5" power line to the LED strip run directly from the USB port's +5 line, or does it go through a power regulator?
Thanks! I'm loving the BlinkyTape so far... and I'll be publishing some animations for it this weekend, I hope!
