I am experiencing sporadic color changes of both single pixels and entire figures.
I am looking for recommendations for controller modifications to make to get through this season.
Project: outline lighting of 2D figures in a nativity scene (24ft). 12 figures plus stable.
Need to be able to disconnect/disassemble for storage so using plugable connectors for power and data
Controllers: three ESP8266 ESP-12E running WLED
mounted to perfboard
1000uf 35v cap across 5v power in connection
Level shifter (I2C TE291) (I tried a TXS0108E - pixel colors were changing everywhere)
LEDs: 5V WS2811 RGB pixel (for all except stable)
5V WS2812B GRB (stable)
Power: Single 5v 60amp power supply
14awg stranded for power bus lines (2)
One power bus feeds the figures for Controller 1 and Controller 3
Second bus feeds figures for Controller 2.
18awg pigtail from bus to figures
18awg line to controllers
The three controllers are spaced about 9" apart, mounted on a railing behind the stable.
The three controllers are fed by a single 18awg bus line about 8’ long, that is
wire-nutted to 12" pigtails coming from each controller box
The signal line from each controller to its first figure is about 6’ long
Each figure has a 2-wire connector for power, connected to the first pixel
Each figure has removable butt connectors on the signal line - F on in, M on out
Data lines for figures are chained together with 20awg jumpers, most 18"-24", one on an end that is 8’
Controller 1: Stable - 3 segments, 44/52/44 (140 total)
Controller 2: Rt Side - 6 figures, 1 segment/figure, 21/45/53/56/51/49 (275 total, 8’ gap between last two figures)
Controller 3: Lt Side - 6 figures, 1 segment/figure, 63/32/49/65/20/48 (277 total)
The power supply is connected to the same AC outlet as other ‘dumb’ exterior lights.
The ‘dumb’ lights include a set of LED net lights set to a ‘fade’ effect.
If no effects and no ‘dumb’ lights connected, figures seem stable.
If ‘candle’ effect applied to middle segment of stable, sporadic color changes on figures connected to Controller 3.
If no effects and ‘dumb’ lights connected, sporadic color changes on figures connected to both Controller 2 and 3.
From what I’ve read so far, I might need to add a resistor on the data out from the level shifter?
