    So i have the WS2801B led strip, i cut it 4 times and connected it with the following:

    http://www.aliexpress.com/item/F85-...B-Connector-Adapter-For-5050/32293844771.html

    using the RP2

    and
    http://www.aliexpress.com/item/5V10..._1&btsid=62e50576-db1b-475f-ba01-24909f425f3e


    as a power supply.

    I have 90 leds connected.


    Any idea why i have from while to while some flickering leds with random color? seems like it is an electrical problem but i cant figure it out why...


    My next steps it trying to use an external usb hub with external power source .. maybe this is the problem?

    Any idea what else can i do?

    Hi,

    It is not a constant time... but can be every 10 sec for 2 sec flickering or every 1 min for 1 sec.. random.

    Is there a way to check the signal that the RP2 is sending?

    yes of course

    "device" :
    {
    "name" : "MyHyperionConfig",
    "type" : "file",
    "output" : "/tmp/hyperion.out",
    "colorOrder" : "rbg"
    },
