I'm going to be making a small project using about 40 BlinkyTiles and an Arduino, but I won't have any access to a power outlet. How can I power them remotely?
I was thinking of using the Adafruit PowerBoost 500 shield and a 2500mAh li-poly battery: https://www.adafruit.com/products/2078
Will this provide enough power?
Hi Palco, the Adafruit shield you mentioned sounds good, however 500mA isn't quite enough for 40 tiles- you'd be better off using a power bank that's designed to provide >1A charging, such as this one: www.amazon.com/JETech-2-Output-Portable-External-Battery/dp/B00T415OTS/
Also, the battery life is directly related to the pattern being displayed, and the brightness setting- we've found for wearable applications, the highest brightness is usually too much. Using a smaller 4400mAh battery to power a 24 tile project, we usually get 4-6h of power.
