    or also the lack of using a resistor between the data line and the raspi pin.


    It's possible the static you see is the result of 2 things:


    Audio scatter from the source... so disable audio in config.txt

    Or the PWM has to leveled out so use a resistor, 100 ohm something is enough to flat out the signal.

    go to default settings, here you can create more instances.


    Then you go to configuration> ledhardware and there you select the new instance and alter it

    Then go to sources and you can alter that also.


    Tip: use the wizard when you made a new instance


    Goodluck!

    go to logs and post it here or pastebin

    What's the setup? Type of strip. Ledcontroller etc etc.


    Try it with disconnected HDMI

    Try it with static colour on Hyperion.NG app

    Check soldered connections on the strip

    Are they flickering when raspi is booted/Hyperion.NG runs or also without data?


    Are you running Ws281x controller or SPI??

    solder GND to the pins of raspi,make sure you connect GND in common way to PSU/ledstrip and Raspi pins..

    Solder GPIO10 and GPIO11

    Make sure baudrate is not to high or low in Hyperion.NG my setting is 1400000 baud

    Reset time leds is 6000 ms in hardware (standard a 1000)



    I never had problems with APA102 ledcontroller so I think the problem is mainly PSU, connections and faulty hardware

    hello fellow ambilight builders.


    First of all this is just a personal story in general and I wonder why a lot of builders always tend to use the most difficult ledstrip route there is (seems) to get it to lite...


    The one and only SK6812!! =O :| || :D


    why this strip, why the choice to use it. Especially for beginner builders. It's a clone strip...

    see in this forum, the only thing you read about is (big) problems to get it to work. Even with PWM or SPI signal this strip isn't for the weak :P to get it to bloom into full colour spectrum.

    And no it isn't the best, the HD107S is really really good without the white channel separate..

    If you don't believe me I will put a video on the tube to prove it to you.

    You see, alot has to do with proper PSU and solder connections. That will also improve or make the ledstrip worse than it is capable to.

    So make sure using good voltage ⚡️ see and check specifications of the strip. Check the specs!



    if you want a easy build on a raspi then. . Read along. Just used a standard Hyperbian build with build in controller.


    when I first started I used the WS2801 and it was a walk in the park running on SPI with 96 leds only.

    My second strip was a APA102, using the SPI controller with 130 leds was a walk in the park.


    My thirth strip was a HD107s, again it run flawlessly with 300 leds on APA102 controller, only resizing SPI buffer and that was it.


    in this case i like easy, easy is fine and good :P


    All those ledstrips run flawlessly on a Raspi 3b....

    With Hyperion.NG 2.013, so not even the newest branche. I never had to deal with extra modules or channel converters to increase signal from GPIO. Just standard GPIO 10/11 and SOLDERING directly onto the GPIO. Voltage inserted in 3 points on the strip.



    so there you have it, it's a insight and maybe a plan how you also can build it.

    First try it the easy way and then the intermediate way to expert.

    That would be my advice.

    happy builds.


    Greetings.

    I think, but it's only a quess..


    Your router/switch doesn't provide the Raspi with dhcp IP adres, so the device doesn't receive IP adres. Hence, you cannot go to browser API

    Normally Raspi boots under dhcp, static IP adres config isn't necessary (normally I have to say)


    Check your connection/utp cable and see if LAN Raspi port gets green/orange lights blinking

    Make sure router/switch puts out dhcp, or turn on dhcp server option 🤔

    and I have to say, didn't know that was also possible to get the rtsp stream into Hyperion and is far above my Raspi knowledge


    But: I did it with a analog Cam in colour with a 3-11 mm DC lens. That was aimed to the TV and the analog signal connected to a usb grabber.


    It worked but. Colours where somewhat off because of the dark spot when dim scenes is playing.


    BC backlight compisation was ON on the colour camera,

    Result was a meager 7 :)


    cons with this setup was no hassle whatsoever with hdcp/arc/edid/ etc

    it's pwm so only with a scope you can measure it.

    Pulse width modulation is an electronic signal/ duty cycle with intervals.


    Make sure Hyperion is running under root otherwise pwm isn't working correctly, also disable audio output in config.txt

    make sure you have common GND to ledstrip/raspi and PSU, ar least 2 GND on Raspi especially with that connectors


    GPIO connection my advice is to solder it, those pushconnectors are the worst because of bad connections.


    Check voltage at begin and end of the strip

    Maybe it's a plan to merger every SK6812 topic into one big one.


    It's really a difficult ledstrip to get it working, in this way all tips and tricks are bundled in one topic. I read a lot of problems everywhere with only this strip..


    Call it

    The big SK6812 topic, for all tips/problems/tricks


    It's just a idea 💡
