LPD8806 parallel connection odd problem

by nervusvagus on Sun Apr 15, 2018 2:57 pm

I tried connecting some 1 meter LPD8806 strips parallel and I'm having a strange issue.

I use cable connectors, the type that comes with the strip to divide power and signal from Arduino to 3 different branches with connectors at end. Basically the torso and arms of a stickman.

However somehow only any 2 of these connectors work at the same time. If I connect the third strip they all light up random bright white colors. Any combination of 2 works, but the 3rd strip when connected messes up things. I run a very simple animation of a few leds traversing, and power them from a simple powerbank. Anyone know what solution I can try?
