Correct

Damnit...wanted to start, but missing the cables for connecting the Pi. Probably someone put them to the waste with all the christmas packages...damnit damnit damnit.

If you have some spare UTP / CAT5 cable around you could Macgyver the Pi cables , just cut and solder the ends a tiny bit.

 

[The_Stig]

Nah...as I am totally unexperienced on soldering its too dangerous for me. Waiting for the spare parts now...

 

[The_Stig]

Hah...it magically appeared in between the dirty laundry but vacation is over...lets wait for the weekend.

Is there a reason why one should start center down on the TV with the stripes? I mean with starting e.g. in lower left corner its less cutting and soldering...

EDIT: And: what is the best way to multiply the power connection to the middle of the leds strip? Just solder the cables together and put a shrink sleeve over it?

Should be the same amount of soldering as you have to cut 4 zones total and connect 3 corners together, start and end point might already have connectors with a sleeve and sometimes even a power connector.

Would try power the start and end point first and see if it can do full white, with my 218 WS2812 led setup only that is required.
If you can't do full white the method @Lightning303 used recently with connecting power in the middle for every zone is the best way to go about it, with 5V it all comes down to length as the longer it gets the more the voltage is gonna drop.

Would shrink wrap the open connection points where it can touch something else (back of tv / other cables), normally only do it for the start / end points as that can flex a bit when connecting everything up (heavier cables / jack connectors).

Hrm, 3 corners to connect?
x3--------------x4

x2----x1 x6----x5

X's are marking the connecting points. x1 and x6 has connectors. Still 4 corners to connect/solder.

Alternative:
x2--------------x3

x1 x5-----------x4

EDIT: Second vertical line should be on the right side...doesn't work here in editor.

So one corner less. So again, any reason not to it this way?

start and end point might already have connectors with a sleeve and sometimes even a power connector

So I can use whatever part of the LED-strip? E.g. cut LEDs 1-34, use 35-67 for something else, and then use 68 to end of the strip? Sorry for all this dumb questions, I just don't want to make something wrong.

Sounds good. Will do. Gotta read a bit more, how I do all these tests and colour adjustments...

 

[The_Stig]

And another one: Instead of soldering the LEDs in the corners, how about that?

Should work and doesn't loose too much space in the corners.

EDIT: No, this is for 10mm, my stripe is 12mm...but still: good principle or not reliable enough?

Btw you can use my image of post #49 how to connect the stripes and all other things to the pi.

On the edges I also used those wire connecters, but from another manufacturer.
