Hello everyone! Total novice here. I have a programming background but no experience with electric circuits/soldering etc. My current setup/ idea is as follows: hdmi switch > hdmi splitter > hdmi capture > led strips connected to RP4b w 8Gb GPIO 18 > led strips powered by a cable with THIS connector to a power supply. I have decided to go with 60 led strip and has already selected the ws2813. By my calculations, I would need 5v 18amps to power 3.9 meters behind my tv. This also means I would need to buy it for ~$25-30. Then I have discovered ws2815, which uses 12V and doesn't have a voltage drop. By my calculations, it would need 12v 4amp power and I have 12v3am and 12v5amp power bricks laying around. The price is almost identical to buy 2813 + power supply or ws2815 + less e-waste. While doing research, I found 2 things that worry me. First, feedback on some of the power connectors say "do not overpower, 5amp max" and with ws2813 I would need to use 15amp (although the LED vendor sells power brick with the connector). Second, I read a comment that going 12v without soldering is dangerous and should be avoided. I would like some feedback on my current set up and thought process. Don't want to fry either LED strips or RasbPi. I can upgrade to use a breadboard or USB CONNECTOR to enable sound later on but for now, just would like to connect/ ground to Rasp Pi directly. Thank you in advance!
