[QUOTE="Rick164, post: 1196345, member: 17766"] Hi [USER=159933]@matthew henry[/USER] , For APA102 you can just connect them straight to the RPi3 SPI connectors without level shifters as it's all 5V logic, do that over here with an APA102 600 led setup (144 leds p/m variant) and works fine with > 200 FPS possible. Hyperion has linear smoothing which lets you tweak the experience a bit, currently have it set to 160ms @ 40hz which is smooth but not too slow as the APA102 chip you can drive a lot faster than the old WS2812 ones. Some early build videos: [URL]https://forum.team-mediaportal.com/threads/diy-amblight-project-guide-hyperion-ws2801-ws2812b-apa102.128526/page-24#post-1174157[/URL] afterwards bumped the power supply to something more reliable and added extra cables so results are now perfect. Only needed if you want WS2812 but otherwise stick with SPI and direct connection to RPi. Will only add extra steps and hardware cost so would got with the RPi solution, only tested with RPi 1/2 so far but hear users using the newer RPi3 without any mayor issues. If you do run into any you can also check out the Hyperion forum btw :) [URL]https://hyperion-project.org/[/URL] [/QUOTE]
