    Not without quite a bit of extra circuitry.
    You'll need a transistor circuit that enables to switch each color individually and program a driver for it too that works with hyperion. Also, you'll need a cooling setup most likely, because the transistors will need to be able to handle 3-4A each.
    And, the biggest issue of course: You can't address the LEDs individually. You can only change the color of the entire strip, which makes it completely useless for ambilight purposes.

    Just use the ws2801 or apa102. Why difficult if easy is possible :)

    Hello, first of all, thank you for the great tutorial!
    I followed this guide and have fully working 'raspbilight', except one problem:

    I've added simply on/off switch on power supply wire, to easy power on/off led stripe.
    This switch breaks one of two wires incoming to power supply.

    My RPi powered from TV USB port and HDMI always connected. TV in stand by mode (powered off via button on remote). Led ws2801, PS 10A, RPi 3b+, TV LG 49"

    The problem is, when I power off the led stripe, random - one or two leds, start randomly blink/flick every 1-2 minute. Looks like led stripe recieving small amount of power somewhere, and trying to power on.

    What i've tried:
    1) Disconnected led power supply plug - no blinking
    2) Connected power supply plug + switch in OFF position + disconnected RPi USB and HDMi cables from TV - no blinking
    3) Connected power supply plug + switch in OFF position + connected USB OR HDMI (both, or by one) - blinking

    Could it be power leaking from TV hdmi/usb through RPi to power stripe?
    Should I add 300-500Ohm resistor to DI cable as it described on PWM guide (https://hyperion-project.org/wiki/3-Wire-PWM)?

    I've added capacitor (6.3V/1000µF) to wires (5V/GND) on power supply output, it didn't help.

    Tv usb port is not more then 5v 1a. This is not enough for the pi. Even it is not good for the pi.
