HyperCon Sk6812 strip - Does anybody have this led strip and is working? What is your setup? (help needed)

I have lights WS2812b (5M) + RP B+ and grabber V4L2 on Openelec 8.0.4. Everything was working ok for few months. Now when I turn on ambilight lights are working for sam time ok (different time, some time 5 minutes - sometime hour), and then they freeze on the left side of the TV (from approx. 185 led till the end of strip 271. ) After that left side won't work anymore, sometime freezzes on last color sometimes on black. The right side working ok. If I turn of light and turno back again it is not helping. I must wait with turned off for approx. 10min, then I turn them again and is working for some time and again freezes. It is driving me crazy.


Can you please help me what is wrong with my setup? Thank you!

EDIT:

I bought new led strip. Now I have sk6812 with neutral white, but now is not working last 60 lights and on others color is not ok. Almost all the lights are shinning only white.

Led SK6812 RGBneutral white
Raspberry B+
Ambibox dreamcolor
Grabber V4L2
all on Hyperbian.

Last 60leds dont work, others shine white mixed with color, lights are moving with picuture, but all seems white. When I try to get only one color with color wheel on my phone, they are changing to color - again white mixed with color.

What I did wrong?

 

I don't think it's your setup. Either the LED where the problem starts, or the connection.
Check if there is a solder connection in the stripe.
That could be a temperature problem, resistance or something similar.

Openelec is old. Try libreelec to test it.

 

I use Hyperbian now and have this problems. And if I use Hyperion on my phone and choose only red or some other color, they shine white again.

 

Maybe the strip is the problem. Maybe you bought a white strip and not rgb

 

No, it is RGB with neutral white . Every second light is shinnig in color.

Now, my setup has new lights, and I don’t know how to make them work:

On settings I use adalight (115200 baudrate), If i change anything lights go off.

Thank you for your help!

 

I can not help you. My setup is different components. Maybe someone else could help you further buddy.

 

Ok, thank you for your respond . Hope someone can help.

 

Anybody knows this? Struggling for days now and can't find how to resolve problem. Do I have to buy different lights or..?

 

I think Ambibox dreamcolor doesn't support RGBW stripes.
Use Wemos mini D1 with WLED software.

Thank you, will order Wemos then, do I need anything more ?

 

Take a look at the WLED-Wiki.
Actually, you don't need anything anymore, maybe a Level Shifter.

One question more I have this power supply connected on both side of LED strip 5m (60 per m) - 272leds :

Is it enough ?

 

I use 268 led and it is enough to supply at both ends.

Regards pclin

 

Sorry my mistake, now I se that mine is 5V 8A, is it still enough ? And which type of level shifter you suggest ?

 

5V 15A would be better for for brightest white.
With WLED you can also limit that to 8A.

Regards pclin

 

i suggest that you measure the voltage on the supply, it has to be 5 volts exact (under load)> everything more will hurt the lights over time, everything less will downgrade the datalines

 

you can connect the lights directly to the GPIO pins ( SPI device) of the PI > its for 95% of the time no problem and will work. Ground everything to each other so pi to ledstrip/ ledstrip to powersupply/ powersupply to PI. Without a levelshifter it can work, the GPIO is able to put out 3,3 volts of dataline while the ledstrip wants to have 3.5 volts.

 

Check the directional arrows on the LED strip. I had the same issue and it ended up being because I wired one of the LED strips backwards
