Comment on How to solve power supply whine with continuous dimming LED?
BigDanishGuy@sh.itjust.works 1 year agoThis range is a usable - there is no visible flickering even at very low duty cycles.
Before deciding on the frequency, and then mounting the strip in a position where the LEDs are directly observable, you should try moving the LEDs fast relative to your eyes. Eg. take the end of the strip and wave it from side to side. You may notice flicker at frequencies below 200Hz.

Ok, good thinking. I settled on 1000Hz and also made it something in remotely reconfigure should the need arise. That combined with the other suggestions, and getting a better power supply has made the system whisper quiet now.
