Hi everyone.
I am building my first hyperion setup. I am a complete newbie.
I already have all the parts and have configured the software grabber (got picture, right colors).
I am using a Raspberry Pi Zero 2W and a 5v SK6812 led strip and a 10A 5v psu.
Can you help me understanding some stuff?
1 - Can I connect the SK6812 directly to the rasp? I have seen some people doing it but others add an ESP32 in the middle. Why? Do I need it?
2 - If I connect it to the rasp, I must use GPIO18 and also wire several grounds, right? I am using a rasp without pin headers so I must solder the wires. I need to get them right 
3 - It will we an aprox. 4 meters led strip. Do I need to power it from both sides?
4 - I was thinking in having the controller stuff (rasp and psu) on the floor (not behind the tv) but that means that it will add an extra 1, 1.5 meters of cable from the psu and rasp to led strips. Is this ok? I have read somewhere that cable length is a factor to mind.
5 - The raspberry will have it's own power, so I must connect both grounds (rasp and psu), right?
Thanks in advance for your help.
Regards,
Mike
