Akali Mask - 54 x APA102 LEDs on portable power source
Posted: Mon Feb 04, 2019 5:35 pm
Hi there !
I'm currently looking for the best way to power 54 x APA102C LEDs from a portable power source.
I plan on using a PowerBoost 1000C booster/charger to power both the uC ( either arduino uno pro or Espruino ) and the LEDs, which 'll be at their brightest & "fully on" on their R,G & B channels for at least 1 minute, switching patterns every few ms in a synchronized manner.
I started with using a PowerBoost 500 booster/charger + a "supposedly 12000 mAh" 3.7 ICR18650 ( before reading more on that scam & finding about the 3600mAh maximum .. ), but I'm not sure if even other batteries 'll be able to provide the required current discharge ( 60mA * 54 LEDs 'd mean 3.5A power source ), or if I need to use two boosters + single battery, or two boosters & 2 batteries, or even directly a 5V power bank ( ex: https://www.adafruit.com/product/1566 )
iyo, what 'd be the best way to provide the needs to such power hungry setup ?
ps: in case the subject is of any further interest to anyone, this is for a Cosplay part ( "Akali's mask" ) and the goal is to provide synchronized transitions between ~hollow leds segments ( see the entire thread & some somewhat-dirty poc code at the following link: http://forum.espruino.com/conversations/330092/)
This being said, wishing the reading a nice evening of coooode ;)
Thanks in advance ++
