First I want to say that blinkytape is a super fun product. Great job you guys.
I'm considering running a couple strands of LEDs in parallel so they simple to program and cover a lot of space. Anyway, it'll likely be several hundred LEDs which draw a significant current. I've noticed the blinky controller sort of will flicker or not run the sequence properly sometimes. I was only using a 5V 1A power supply so it was probably underpowered for the 144 LEDs. If I ran the LEDs at all white, it takes about 8amps. I guess my question is how much could I run through the blinkytape control board before it behaves erratically?
Also could I solder to the 5V and GND pads on the back of the board to bypass the micro usb when using battery power?
My final question... is there a way to prevent the LED strip from quickly flashing when connecting power? Let's say I make a sequence in pattern paint that is black for the first 5 seconds, then turns on to show color. Say I have an application where I flip a switch to power the blinky controller and strip receive power then start as normal. Is there a way to eliminate that initial flash, or would I need to create a circuit that powers the controller then the strip right after? The flash sort of ruins the surprise of the lights slowly turning on from black.
Thank you for any help!!
