    Hi folks,

    I can't seem to find the modified Adalight Sketch mentioned in the documentation. Can anyone point me to it?

    Also, what is the advantage of using Adalight vs directly connecting to pin 18?

    I did a test today and connecting to pin 18 seemed to work. My setup is:

    Rpi2 B+
    100w power supply
    usb hdmi grabber with loop

    Everything seemed to work except that I noticed some random flickering during bright scenes and it was dimmer on the right. I'm guessing it is due to only powering the strip from one side. Total leds were about 270 using 60leds/m, left, top, and right only.

    Few more questions:

    • After how many leds should I inject power?
    • Why is the voltage on the strip only 3.8v? I only have a breadboard in between. I'm using 24awg jumper wires to connect the strip.
    • How can I lower the latency further? I already set it to capture 640x480 at 30fps only.
