Hi everyone, I am at my wits end right now. I’m trying to control a strip of WS2812 LED lights via a brand new resin enabled Raspberry Pi 3 B+. The strip is this one: https://www.amazon.com/gp/product/B018X04ES2/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 I have it wired through a logic level conv…

Looks like @sqweelygig had a project with similar hardware? Maybe there are some pointers, or he has some useful feedback? [image] Christmas Lights! Project help Well, it was a Hack Friday on Dec 1st, and I had this spare string of WS2812 NeoPixel LEDs. What happened nex…

Indeed I have done a WS2812B controller board! I used the Pi Zero W, but that shouldn’t matter. Thanks for the ping Gergely. The things I notice about these two projects are: Note that your link references a WS2812B string of lights, and your description states WS2812. They are different, most …

I am using all 5 meters of the strip, so I wanted to keep the input voltage as high as possible to avoid fading over the course of the strip. To that end I will be powering it from both sides with 5V 10A supplies (the full 5m could pull a max of 18A at full bright white). I was also trying to use th…

Could you try cloning https://github.com/resin-io-playground/ChristmasLights and seeing if that works?

will do after work today. I’ll report back here after I do! Really hoping its not a dumb issue on my end…

I ran into this issue yesterday and was hoping my issue on the rpi_ws281x_native GitHub would have been responded to by now, but I get this error when npm tries to install the library: ../src/rpi-ws281x.cc: In function ‘void init(const Nan::FunctionCallbackInfo<v8::Value>&)’: [main] ../src/rpi-ws28…

I’m not sure what the default is at the moment, but that probably isn’t as important to you as being able to steer which version you get. You can do this by appending a :<version> to your FROM statement. Details on our base image page https://docs.resin.io/reference/base-images/resin-base-images/ ,…

Indeed it was the node version that was causing the issue - rpi_ws281x_native isn’t yet compatible with node 10. Switching to an image with node 8 (resin/raspberry-pi-node:8) fixed the issue and I’m now in control of the lights! Thanks so much for all your help. Now on to the fun stuff…

Thanks for taking the time to close the thread off for future audiences, if you need any other help you know where to find us. Oh, and feel free to update this thread when you’ve got some pictures!
