Ok - I know, its totally my fault. As a sound guy from way back, I know power cables are supposed to cross at right angles to data \ sound lines to avoid interference... I'm pretty sure this is my problem, and i'm wondering if anyone has come across it \ has an alternative solution to relocating the whole shebang.
We have WS2811 strip run on conduit under our eaves. This year, the wife wanted icicles, and thanks to somebody on here designing a set of dumb RGB icicle strings, she got her wish. With time and budget limited, we decided the easiest way to mount them was to cable tie them to the existing conduits.
This puts 12V dumb RGB string parallel to the strip.
What i'm seeing now is random coloured strobe effects pulsing from the strip at random points. All very low intensity (i'd say 10%) - but very noticeable in a 'blackout' scene.
The controller is brand new, as are the icicles. the effect only happens when the controller (Ray27) is outputting, but it happens on sections of the strip that aren't plugged in.
I've done a little diagram attached to this post so you can see what i mean.
As a key - (ignore the red line and orange star):
To trouble shoot, i've done the following:
thanks in advance for any assistance.

As a key - (ignore the red line and orange star):
- green line is output 1 of 2811 (2 strings)
- blue line is output 2 of 2811 (3 strings)
- i've numbered each segment 1-5
- the icicle segments are indicated by the white lines, and they follow the same numbering.
To trouble shoot, i've done the following:
- tried the Ray27 board in test mode, and driving from DA E1.31 and LSP
- tried an older Ray27 board from another element in test mode
- tried unplugging icicle segments 1, 1+2, 1+2+3, 1+2+3+4
- even with only segment 5 running, and all others unplugged it still causes interference on segment 1+2 of the strip
- all of the extension leads from the controller to the icicles run on the ground. all the data extensions to the strip are in the air
- There is a setup difference between output 1 and output 2 - output one has a longer cable run, so the speed for output one is 2600, whereas output 2 runs at 3000. I haven't tried changing this yet.
thanks in advance for any assistance.
