yes I have,
Look up the specs of your SK6812NW strip, mine is running under exactly 5.3 volts ⚡️ (HD107S) to achieve most accurate colours possible. Also better for the Raspi to run at 5.3 volts..
Solder your contact points to reduce resistance
And look at section ledcontroller and choose the correct algorithm for your whites.
Go to youtube video and check ✔️ your colours in live feed and your ledstrip simultaneously, seek for ambilight/govee videos
Set colourscheme in hyperion to default and Gamma on 2.4 red/green/blue
Run the ledstrip at 30% brightness to see if the whites improves with less luminance.. 🤔
That's it for now.
You have to increase the SPI buffer in CMD bootline then you can address more leds than only 255
But be carefull because the Raspi won't boot anymore if the syntax is not put correctly
nothing seems out of the ordinary to me.
The only thing I wonder is why you altered the colours in colourscheme to different than default.
I never did that and only had to change the Gamma settings with ledstrips as WS2801, APA102 and HD107S
In my experience the only colour" that will draw most power thus current from the PSU is shiny 100% brigtness white
Every other colour will draw less current, maybe for separate channel white ledstrips like the NW /CW or WW types that's different.. 🤔
I'll beg to differ this...
the most important is the PSU and the way how he injected the power in the strip.
How much leds, what voltage ⚡️ and what is the power drop after 150 leds or so...
If voltage thus current isn't correct you never get a satisfactory colour scheme out of your ledstrip.
Settings in hyperion alone isn't going to cut it then.
note, vitman
A tip of mine is to lower down the brightness of the leds to 30%
If the leds going to shine ✨️ bright whites but at lower luminance you'll know that you have to upgrade the (total)power to the leds.
Just a tip.
Goodluck!
how many leds do you have and how did you Inject the power?
Iff there's a power drop then the colours especially the whites will turn out yellowish
Okay then I am signing off..
Ground and 3.3 from the pi pins to the LV side of the level shifter. The HV side of the level shifter comes directly off the PSU.
Looks okay to me. Make sure common GND
there's a lot of problems I noticed to run SK6812 directly from the PI, even with levelshifter.
It's better to use a microcontroller like ESP32+ levelshifter and run Wled, for that ask pclin
Yes it is,
login as expert and change the capture settings:
Capture encoding stream to Mjpeg
Resolution 720P
Size decimation 2
PSU power, is it sufficient, measure Amps
hardware connections/PINs, check them for resistance
injecting power at middle and end of strip,
do that with +5volts and GND
Ws2801 can run without levelshifter or nodeMCU.
Just connect DO and CLK to GPIO10 and GPIO11 and make sure common GND.
When more than 255 leds then increase SPI buffer in CMD boot line. For that look up my old posts
use this settings they worked for me at original Hyperion 1.0 version.

kunstoff-led frame is my V1 build, i made a update about that one.
i have now V2
the basic is PVC tubing ( electrical) with 16 and 19mm and metal braces on the TV, frame connected with tyrap to that
How do access to the console on raspberry when I boot in order to offer you more info?
if i may;
The tuturial showed you how to alter the wpa_supplicant.conf
i don't use that but just go to the GUI of the Raspi and alter the raspi-config
Attach a screen to the HDMI port and see if you can login with the pi/raspberry
then you should see a screen like this with Hyperion status running, also you see the IP adres the Raspi has received from your router.
It might be a splitter problem
i see its a Bidirection.
you have two settings:
You can't display 2 monitors at the same time, it says in manual. You can only CONNECT the monitors but not display it, you need the button to select 1 or 2.....
you have the wrong one, look for a USB loop device
now i want screen capture however its just displaying black, any ideas
test Hyperion direct from the source without a tv connected, see if the webpage REMOTE section shows the capture device.
has to be visible there with about 240 priority level.
if it is: go to the screen up right and see whats displayed there, should be a copy of your screen.
if not ( only black or rainbow signals) then check the HDMI cables and/or HDCP connections.
or power the capture device NOT from the Raspi but charger or TV USB socket
note: for splitting drm content you need at least HDCP2.2 build in the splitter, if it isn't it will go black on you or in Netflix/Disney give you HDCP warning and no playback.
It's to protector to them you can't copy the material online streaming
Goodluck!
did u use this code.
looks like ws281x leddevice is ON, also looks like the PI is taking back the PWM soon its fully booted.
Try this and put a extra line in config.txt without the # before the line an save
Sudo nano config.txt
For your information
GPIO 12 and 18 is "same group PWM0 channel
GPIO 13 and 19 is "second group PWM1 channel
can you provide the debuglog in here? Go to logs and select debug. Then copy paste
the strip is working now, you can test it with effects. You have a video problem now.
Set all the leds in Hardware count
Go to the webUI (ipadres:8090) and go to remote section. There you can test if the video source is visible.
You can also choose a effect, set duration of the effect and then you should see the effect running on the strip.
You have the rainbow 🌈 signal now, means that video signal can't reach the Raspi. So you have to change the splitter or such.
But first try the effects
take the white leads, connect them with a wire to GND pin on the Raspi.
there's diffrent Raspi GND pins, take the ones that's closest to GPIO18 ( hardwarepin 12)
so hardwarepin 14 and 20 GND
Ground at Raspberry Pi GPIO Pinout
for the better you connect to those 2 GND pins with the white wire. You need to have a common GND
the wiggeling effect means there's a resistant between the pin and the jumpercable.
best is to solder the leads on the pins directly, to prevent resistance.
your PI needs to be connected with GND from the leds.
so: take 2 GND pins of the PI and connect them with the white wires.
that should do it.
furthermore: 5v3Amps is not a lot but enough to test your setup with, you may want to upgrade to a more powerfull PSU.
chance is that the colours will not be even, especially the whites.
