I bought about 70m of them from BTF last August, used them for halloween and didnt take them off in the Western Australian sun, over several 40C summer days. No issues with the strips. I used the non-bright version and they were sufficiently bright. Their power supplies are reliable too.

Thanks all for your input; I certainly want to get this resolved but in the interim have used more controllers to get me through this season. Will revisit this in mid Jan for sure! @TerryK Thanks for doing the superb diagramming and @Srmorgan and @BAZMick for digging up the logic level converter...

@Srmorgan The Wemos is based off an ESP8266 chip, so you might be on the money here. Although, I'm wired from the chip straight into the LED strip and I would've thought that past the first node, the WS2811 chip would resample everything back to 5V. (Because if it doesn't, then why is the...

Good pickup Orchid, I mislabelled; it's a 12V power supply. Linking cable tested and not cross wired I'm perplexed by the data issues because others have gotten away with much less. I don't know if the ES Pixel Stick firmware takes some shortcuts with the PWM signal that makes it more...

Answers and pictures below: Possibly the most important useful bit is that I have identical setups across the other parts of the house, which work fine (almost) end to end connected. (i.e output plug connected straight into the next strip). The only difference is I have extended the distances...

Thanks for your replies folks. (with no null pixel) I tried adding a ground line connecting back, but the flickering became worse. Then I tried the CAT cabling solution, even crossing over the twisted pairs so that the data and negative lines are in different pairs (a la TIA568 ethernet...

Thanks heaps Franky. I didn't realise that PWM signal could be helped by twisted pair; I thought it might have needed dedicated + and - signals to cancel out noise. Still couldn't get it to work. I tried to use a 3 LED strip as a null, but it didn't seem to fare very well. I'm guessing it's...

Well.. telling xlights that one pixel is null didnt help. My understanding was that normal pixels can be made into null pixels if you drive them to zero. In essence I thought that some power draw from the pixel after the chip would drain the signal.

Nice photoshop work there mate! I'm using 1.5mm mains wiring as the cable, so it should work better than Cat6 cabling; if copper is the main reason for the suggestion. My arduino is using the forkineye ESPixelstick firmware, which doesn't have null pixel config. I'm wondering if simply telling...

What sorcery is this! Alan's video is exactly what my lights are doing, but he gets up to 9m before he has issues, while I'm experiencing it at 2m (even with 1.5mm wire!). Unfortunately I won't be able to get these null pixels in time :/

Hi folks, My setup is 4x2m vertical strips driven by the same pixel controller (Wemos D1). They are all connected along the floor with 3 wire cable (1.5mm2 cable), which is where the 12v power comes from. The WS2811 LED light strips are all driving upwards, then the middle wire (data) branches...

What layout would this be on xlights if the bullets were individually controlled? xLights trees are layered, unless there's an option I'm missing somewhere (I'm sure I am).

Very nice djgra ;) 200pcs seems like the market rate for a cheapie right? With everyone else reporting them, they might be incentivised to please you.

Yup I got a blanket reply for: " Hello buyer, due to Amazon product information display error, the product you are shopping for is 12V full color 50PCS. May I ask if you still need to shop. If you don’t need to cancel your order here " Domestos, you could have probably gotten away with your...

So buy 5 of these right while it's cheap? I mean the other stuff that this guy sells is priced quite dearly. Amazon sometimes has some faulty pricing algorithms. I once was eyeing a $40 microphone, which I saw discounted to $30. I tried to buy it but there was a fault in the backend that didn't...
