[SOLVED] 5V PSU led strip

I have bought a WS2812B ledstrip (5m 30leds/m) and a 5V10A psu. During my first test my lights (well at least the first few) go crazy.

I also notice the PSU make a chirping cricket noise and the green led is not stable. Nor seems the output voltage to be stable.

I make a quick video:

Am i doing something wrong or do i have a faulty psu ?

This relates to supporting openHAB how?
This is an openHAB forum not a generic Home Automation one.

Some power supplies require a load to function properly.

Some power supplies require you to connect a voltage-sensing terminal to the supply.

This is not an openHAB question.

Turn it off and put it in the bin.
Anything electrical making that kind of noise is DANGEROUS

This is in fact the -> Hardware <- -> DIY <- area of this forum.

He is asking about a hardware he wants to implement himself.
So there es exactly no problem with his question here Bruce…


FYI: I sent it back, got a new one and this one is behaving as expected !
