So...ordered everything..let the games begin...

Thanks for you input so far guys...more questions to come!

So for OpenElec, I will take this one? http://releases.openelec.tv/OpenELEC-RPi2.arm-5.0.8.img.gz?mirrorlist

As the older one isn't available. And why not take the 6-Version? Any problems with it?

Yep that is the correct link, can try V6 but for Hyperion only there's no benefit as you can even run 4.2 where it runs fine.

Hey,

i hope the_stig is allowing me to hijack his thread shortly

i would go for nearly the same setup as the_stig, but a little bit bigger

My shopping list for now is:

• APA102 72/m 5m: http://www.aliexpress.com/item/1m-5...-PCB-24-36-60-96-leds-pixels/32322326979.html
  
• Connectors: http://www.aliexpress.com/item/whol...r-SMD-5050-3528-RGB-color-LED/2046119929.html
• PSU Connector: http://www.aliexpress.com/item/Hot-...-Plug-Jack-Adapter-Connector/32298449844.html
• PSU: ??????

I own already a RPi 1 with case and 5V PSU. So no need for that. Also some female/male cables lying around here somewhere

My tv is a Sony X8509C 55" with a size of 123,6cmx72.2cm. Therefore i need around 4 meters led stripe. Which PSU should i use for that? How much power do i need for 4m x 72pixel/m?

Another question is: How do i split up the power from the psu? Just split the power after the PSU connector to every 50. LED? So i need to split the power 6 times to every 50. led?

Many thanks in advance.

Regards
Chris

APA102 72/m

I would say there is no real need for more than 60leds/m, especially not if your tv is free standing.

PSU Connector: http://www.aliexpress.com/item/Hot-...-Plug-Jack-Adapter-Connector/32298449844.html

I remember vaguely that me and @Rick164 already mentioned that his one wont work.

PSU: ??????

Number of leds times the current 1 led needs. Or as you have this information in watt per meter. It would be Watts per meter devided by the amount of leds per meter, devided by the voltage, times the total amount of leds. This will give you the current for the whole system . So you will need a psu that can provide this current or more. Which will probably be one of these Meanwell ones, so the PSU Connector istnt needed in any case.

Another question is: How do i split up the power from the psu? Just split the power after the PSU connector to every 50. LED? So i need to split the power 6 times to every 50. led?

I would suggest to connect to the middle of every side strip. So in best pracitce you would need 4 red and 4 black (4 times V+ and GND) wires. And every strip would be connected via 1 black and 1 red to the psu.

4m x 72pixel/m?

1 leds = 60 mA
so for 123 cm = 89 Leds = 5.34
and 72.2 = 52 leds = 3.12A
so for all the side ; (3.12 + 5.34) x2 = 16.92 A = 20 A

Meanwell

yeah, buy manufacturer PSU is recommended for limited fire start , true ?

My tv hangs on the wall. On the top there is around 8 cm space to the wall. on the bottom there is only around 2 cm space on the wall. But the tv front is looking a little bit to the bottom. So the bottom is nearer to the wall as the top. Also the tv is much thicker at the bottom. What to you mean? Is 60 enough?

PSU: ??????

Number of leds times the current 1 led needs. Or as you have this information in watt per meter. It would be Watts per meter devided by the amount of leds per meter, devided by the voltage, times the total amount of leds. This will give you the current for the whole system .

How to use this psu? If i understand correctly are the connectors 1 to 7, 7 + connectors and the little screw on the left blue pcb ground? So i can connect the 4 + connections to 1-4 on the psu and the ground to the little screw? or is this the input of the power? L and N and GRND?

hum, i think my translation is not good, was do you want say with " mh" ?
