Started this project about a month ago thinking it would be fun and easy but I kind of regret it cuz it's been a pain every step of they way. I guess I'm learning a lot, if nothing else, never done anything like this before. I think I'm so close to getting it all working, but of course there's a brand new problem in my way.
First, my build:
RPi 3B+
SK9812 RGBW 60led/meter strip, 95 LEDs total (the 60/m seems excessive, thinking maybe 30/m would have been fine, but here we are)
32GB micro SD flashed with Hyperbian 2.0.0-alpha.9
Generic cheapo capture card (
Generic cheapo HDMI splitter (
Generic cheapo 5V 15A power brick (
AV receiver as HDMI source hub (Onkyo tx-nr575, if it matters)
LEDs controlled by pi via PWM ws218x on gpio 18 (i'll admit, I don't really know what this means)
Ground pin on Pi connected to ground wire of LED strip with a jumper wire
Previously I was using a 10A power supply but it apparently wasn't quite strong enough and kept disconnecting the capture card, esp when LEDs turned bright.
New 15A power supply fixes this, but the new problem is that the whole strip will now flash bright white (sometimes green) at seemingly random intervals. Sometimes it will be every few seconds and other times it will be several minutes in between. This is especially annoying when I think I'll have it fixed before it will FLASH out of nowhere again. Current test is to use the 15A supply for the pi, and the 10A supply powering the LEDs which I think has improved the situation somewhat, but I'm not totally sure.
Any ideas what might be going on? I'm very much looking forward to being done with this lol. It's very nice when it works though.
Thank you!
