Neopixel christmas lights

I may be a bit late for this, but for the season i programmed some nice neopixel patterns to use as christmas lights

Today i finished the project by putting the 150W meanwell power supply in a nice box, together with the maple mini, it’s now just plug in the box & the neopixel strings to the box, and enjoy the show.
In the video it’s driving 450 neopixels .

No valid link, no video, no fun…

maybe a DDNS problem?

Which digital LED strip did you use?

Looking on eBay and AliExpress there seems to be a lot of different types available.

This one seemed the best value on AliExpress

But its hard to tell.

Do you have any recommendations ?

Thanks Dan.

Unfortunately Amazon do not have a presence in Australia ( apart from selling books )

these are all ws2812 strips (the one filmed is 60 leds/m)
they’re a bit more expensive
but wow, didn’t know they were dumping the ws2811’s at such prices . might want to buy some of those too

Also a difficult decision is 5V or 12V strips. the 12V are easier for longer lengths as there is less current needed for the same amount of power. But after some googling, i’m pretty sure the 12V strips just group sets of 3 rgb leds together, so you no longer have control over individual leds, which kind of sucks and defeats the point of neopixels.
The current demand is a royal PITA with the 5V pixels however >_<. my current setup is 450 leds, which can have a peak power of near 150W, that’s 30A >_<…. being able to use 12V pixels and get that down to 10A would of course be awesome. It kind of depends what you want to do with them.

Also, not sure if it’s mentioned on this forum already, but neopixels actually need about 3.7-3.8V to fully turn on all colors. Above that voltage you don’t see any difference. The rest is just disippated as heat by the voltage control on the pixel.

Looking on the AliExpress listings, its hard to be sure which driver IC they are using.

Some vendors list both the B and non B versions in the description. I doubt they know what device is on the items they are selling, even if they list a specific IC.

I presume they all work in the same way, i.e as a bit shift register
