Hey this tutorial really helped me. Parts I used were 60/m APA102 LEDS 206 all together no soldering all clips RPI 3 5v 20 Amp Switching Power Supply Converter Surprisingly after the configuration the only problem was that one connector wasnt tight enough. I pressed it with my finger and not it is all good to go. This was one of my first projects where something didnt go really wrong lol. I did a fast color calibration this morning and it wasnt too difficult. my only issue has been that im using one of the cheap SUPERNIGHT switching power supplies and when I wire the 5v from the rpi3 and put it with the 5v from the LED I get the rainbow up top and really bad performance. Right now it is being powered by a separate 5v 2.1a usb and I do not want it like that. After just looking it up I may have it set to 220v mode instead of 120v mode.(wonder how its still working so well though) Ill have to check when I get back. Hopefully this is the problem. What are your suggestions for other settings such as the linear smoothing setting? Also is there any other types of smoothing?
