didnt have the right colors.
Yes the longer stick is the + right ?
So according to you is this compliant to proceed like this, to put the cap with the wire right in the connector ?

yes
but I find it hard to believe that anyone uses red to indicate ground.

It is not red but Orange =)
The wires come from an ethernet câble ^^
I do not owe red/black wire atm.
But this is for testing purposes. I promise you i'll buy some red/black wires.
BTW, the connectors from the leds to connect +5, GND are respectively black and blue. Chinese stuff.

Yes many years ago I had some overseas students ( with reference to the UK ) and I was astonished that inbuilt into their culture was not the red / orange / pink warm colours was not considered natural for a +ve and similarly that black / blue / green colder colours were not considered -ve.

On cabtyre cables where there is only black and white the standard here (Canada) is Black is (+) positive and White is (-) negative.  :-\

No technical PMs.
The last thing you did is where you should start looking.

Well, its even worse with the capacitor and resistor, totally erratic...
Im gonna be done with this stuff, i'm really tired.

Leds dont answer to the code injected to the teensy. Nothing happens.
When i touch DI wire, the first led light up with different colors.
I really dont get it.
A fking simple thing and u cant get it working properly like everybody. im so pissed

Have you tried swapping the clock and data over, you might have a wiring mistake. Swapping them over will not do any harm, it is just it would not work.

The strip is running off 5V but the teensy is only putting out a 3V3 signal. Normally this would be "just" ok, I was running some LED strips like that myself today but they were a different type. Maybe you need a buffer to boost the voltage to 5V.
Have you a 5V Arduino you could try?
Sorry I forgot but are you using the Teensy's own libiary?
If you had a scope you could check that there were signals coming out of them.

Not working, what a suprise.
Using FASTLED library.
I think i'm done wasting time and energy for this shit.
I've seen many ppl doing this, i just copied doing the same.
They don't use R or C ( teensy ) and it just works as expected.
Just going to buy AIO stuff like normal ppl.
Fk this.

Maybe you don't have the patience, concentration or determination required. Hope you find a hobby you like.
