Hi! I’m playing with WLED since few months now and I find this software pretty useful.
Now, I have a big project involving a lot of pixels and I’m wondering which is the best way to build it.
I want to illuminate my back yard. The project is to put addressable led stripe on each fence post (I have 12 fence postes in my back yard). Each of them will around 1.75m long and I would like to be able to control each pixels on each post. I’ll find waterproofed channels/diffusers to host the stripes. I didn’t choose yet the stripe type I’ll pick, but I’m considering using Something like SK6812, which offers RGBW pixels. Anyway, that’s not an important part of my question.
My question is more about the connection with WLED… I’m planning to use ESP controllers.
Operate all stripes as a long one, connecting the data of a stripe to the last one. The controller would be any ESP8266, probably a board with voltage regulator on it (like the NodeMCU), so I’ll be able to connect it directly to the 5V of the power supply.
- Do I need something to “boost” the signal? Since I’m planning to burry the signal cable, is there a limite to the length of the data cable? The longest one would be around 10-15m.
- I find this pretty risky since any problem with the data wire (or a pixel) could potentially break everything.
Similar to the previous one, but each strip is controlled by a different GPIO. A big ESP board with a lot of GPIOs would be required, probably an ESP32 (or use a
MCP230xx chip to add more GPIOs).
- Wire lengths for the data signal could be potentially very long (30-35m). Would I need to add a signal booster somewhere?
- I would be able to create an hybrid with previous options by creating zones with multiple fence posts on the same output. Is there an advantage of doing that?
This option would put one controller on each strip and rely on the WIFI to coordinate them all. There’s an outdoor Access Point, so the connection should be good.
- I there a high risk of a controller being desynchronized from the others? Since it could potentially generate a lot of traffic on the wireless network…
- What kind of cables should I choose for signal + power ? Since I’m planning to bury them (or pass them in a conduit - a plastic pipe)
- Do you think I should I consider a 12V installation instead?
- Any suggestion / recommendations / tips for outdoor channeling of such stripes? I was considering something like this.
Thanks! Any help / tips for building that project would be appreciated…
