I, for one, am hoping that the industry is going to this type of situation. Screw in bulbs that receive their control down the same wire as the...

This looks like a similar product: https://youtu.be/p23YUvWitdk The main takeaway is the S14 'bulbs' have 2 poles so I guess the control cable is 2...

Hey , hold the phone I think you may be correct . I was fooled by the S14 at the link and figured I was seeing a pcb similar to some fixtures I...

Ah right- yes I agree it does look like a 2 pole connector, maybe I spotted the 3 pole one on other products I was looking at. So I would think...

I doubt the s14 bulbs are WS28xx protocol . They appear more like a phillips color bulb with a r,g,b,w circuit board inside . you can see the...

What I see is two multi-wire cables one going into the socket and the other out of the socket. It would be good to see a picture of the bottom of the...

From just the pictures available, I only see 2 wires. Do you have a better image of the connector?

This is what I was looking for. Thanks for looking through the files to help me figure it out.

Generally, you can go up to 30 feet without needing twisted pair. Xconnect seems to be the most popular connector, but if you're talking just wiring...

I use stranded Cat5 or Cat6. It will cary data further than just about any other type of wire. Solid colors are twisted together for ground,...

The current, power and voltage drop I can figure out. :unsure: I wasn't sure if a twisted pair or shielded cable is required because of the data...

I use 4 conductor Monoprice speaker wire. It is available in a variety of AWG to suit your needs. If I only need 3 conductors I can usually pull...

That all depends on the number of pixels, the voltage level, and the distance between each. (Don't forget the distance from the controller.)

I'm a bit late to the thread, and unfamiliar with the design, but that advice looks a bit fishy. The first part is an i2c memory, the second is spi....

Looking at the file BBB_16_Flex.CuTop.gbr from github, it appears that Pin 1 of U3 is on the lower-left of the component layout.

What exactly are you trying to do? I'm guessing that you are attempting to use the files that Scott placed on github to have jlcpcb fabricate the...

That?s a good idea. I think I?ll decorate my parents indoor tree with them. They like the lights that flash different patterns. Sent from my...

I find stuck-at red pixels to be fairly common.

I'm trying to use JLCPCB to create the BBB_16_Flex version of this board. I'm running into an issue though when I get to the product placement...

As for the color problems, you might be able to redeem with an aggressive curve on each color but I probably would just relegate them to an...

I just tested with power injection and it still does the same thing as videos above.

The wire gauge and cca(?) wire doesn't explain why one red pixel is on all the time. Did you figure that out?

It looks like most all of the sequence vendors are having big sales this weekend also...:biggrin2:

Turn them on at full white. If you see the string change color towards pink over the length of the string then you have a power injection issue.
