I’ve finally got my ‘new’ boards soldered after 8 months since buying!
I’ve got my APA102 LED strip running fine.
However, I’d like some advice on the best LED strings (not strip!) to use. This will be for Christmas, so all green wire is a must, then they should be fast with a data and clock signal. And Also 5 volts, so I don’t have to do complicated wiring.
I hope that many of you have already crossed this bridge and can advise.
Both WS2811 strings and WS2801 strings work pretty well for this. There may be other strings that are specifically aimed at Christmas that are compatible as well with all green wire, though I don’t have direct experience with any.
The WS2811 are not clocked, but usually plenty fast given the lower density per meter.
The WS2801 are clocked, and generally work well up to the 2MHz range, but don’t fare well too much above that.
I have a bunch of WS2811 I’m planning on adding to the store soon.
Here’s what they look like (the WS2801 strings are identical except with an additional wire):
Hi everyone I’m a little late to the party and have been stalking the forums but finally ordered my PB! I have a regular strip coming in with it from the ktit but I want to go ahead with some string lights such as the WS2811; I know I want to be able to power the PB with the power supply because I am on a small scale for this year and think it would be easiest for my apartment to do the 5v. Does anyone have any recommendations on how I should power a relatively small system of about 200-300 lights? Realistically with the budget it will be $200 on the high end. Should I just create a post?
Yeah, a new post would be good if you have more Qs, but thats a pretty easy question.
For very small 5V installs, I tend to use USB charger adapters.
For about 300 LEDs, I’d go with a “power brick” style supply. Figure on 0.06A per LED if you run white, about 1/3rd that if you just run colorful patterns, and you can always trim brightness to save power.
…but you probably don’t even need something as big as 15amps for a single strip/reel of 5 meters/300 LEDs.
Creating a tap off the power supply wires, going to both ends of your LED strip, and the the PB screw terminals, is the safest way.
If you put something like this …
…inline with your power supply, and then make the whole LED strip go red, blue, green, white, you could easily find the max amperage it would draw, then go 10 to 20% over that amperage with your power supply and it will surely run cool and last longer.
