These are going to be fun! 😁 100 WS2811 PCBs with holes for common

These are going to be fun! :grin: 100 WS2811 PCBs with holes for common anode RGB LEDs. $21.99 on eBay.

Cheap and fun!

(… and that’s 400 solder connections I’d happily pay someone else to make for me. Like maybe a robot. I don’t have the soldering zen required to do that and do a good job on it… but for those who DO have it, this looks awesome.)

I have build a 8x8x8 led cube I understand your pain…

I find soldering relaxing. Not sure why, but I honestly enjoy it. :slight_smile:

Uh, oh. Someone’s got the LED bug… :slight_smile:

Oh definitely. :slight_smile:

What are you thinking about doing with this?

I’m going to break it apart (it’s perforated) and use 60 pieces of it for the lighting part of the G-Meter I’m building. I’m going to buy more as well and hang them up on the ceiling in my apartment. :slight_smile:

That should prove to be an interesting ceiling!

You can buy them with LEDs soldered on. And with cables attached.

For double that you can get someone else to do the soldering—and you get 28 more LEDs :wink:

Those are very interesting. I have been considering building a spectrum analyzer. I was going to use strips, but figuring out how to mount them (and getting a high enough density) was going to be tricky. Using a few of these might work great!

Yeah, have a trawl through Ray Wu’s site. Every few weeks it seems like there’s a different configuration of strip or panel, with a different pixel pitch or physical layout. If you want higher density still take a look at the SmartMatrix panels which are now supported by FastLED and use 3528 LEDs at much higher densities.

There are a few reasons I bought these specifically, they were cheap, they were bare so I can solder however long of wires I want to them, and I like that they are individual pieces so I don’t have to mangle a good strip of LEDs if I just want one or two LEDs.

I just ordered a set for $19.99 on eBay. Can’t wait to get them. I am looking at a big project using them. I bought awhile ago just the chips and some very cheap break out boards. But it is a chore to solder those little suckers! So much better to get them assembled! LOL

Update: I got mine a few days ago! They work great! Easy to solder. I used pogo pins to test them. I am still trying to get a circuit in working order to drive 12v RGB LED strips with one. Has anyone been able to use WS2811 output to drive the 12v strips? If you have can you please help me?

Thanks!

Hello Kyle, WorldSemi had developed updated version WS2818 PCBs with holes for common anode RGB LEDs. While one LED being broken, it won’t affect another LEDs’ signal transfer, it’s totally with perfect display effect.
