Amazing! (as always)

Maybe I missed this, but if we build a Tri-LED standard  RGB saber, can we switch through colors in any way? Like can we have different color profiles per font? And/or is there a way to switch color while the blade is active within a font?

For the NB it is one color per font. The color profiles are on PRIZM and above. The NB remains the entry level single switch board.

Great, having the option for a different color on each of the three fonts is still quite a nice feature! (Like the CF6-7 had before the 7.5).

that's what PRIZM does (with also more cool ledstrip fx)

A nice set of upgrades and expanded features here. And I see that at least on TCSS, the price is the same as the V3 was. IMO, the value of this little board just went up a few notches. Nice one, Erv.

What would be the battery life of a 18650 3400mah with two strips?

It seems that the shopping of a good strip is quite difficult, supplier doesnt use the same led quality and one strip can be defective really quicker than another one.
Would you have any reliable supplier?

I have no idea where this myth comes from regarding "shopping a good strip is difficult" as there's probably a very limited number of manufacturers in china and those are the same providing adafruit as well.
True, there are some vendors who are doing a better solder job than others, my friend who does pinball mods got a few bad ones over ebay. I personally use aliexpress.

The runtime is probably rather half an hour.

Here a link i found explaining some differences between led:

PSA: WS2812B LEDs may not be what you think they are! - General lounge - VHS

Since i'm not an expert i let you judge of the article

good points, I'll give the sharpie test on the ones I got. The solder job is really the thing too but what I got worked 100% so far. I got a few pixels blowing off a long time ago (adafruit neopixel) but that was on WS2811 and they are somehow sensitive to hot plugging and that was a problem I could reproduce (I fixed my strips by cutting the first pixel when I fried it).

when I purchase, I first make sure that the advertised chip is what I'm getting. Never got disappointed so far and I gave my strips a fair amount of abuse  :evil:

What vendor did you use on aliexpress?
In my article they are mentionning a big one (btf-lightning) that is not that good and another one (mokungit) that seems to be reliable.

Another i didnt really understood, it seems the sk6812 replace the ws2812b because they were not really reliable (maybe it was only at the beginning) and that a lot of vendors are selling sk6812 as ws2812b to not flood the market with a lot of different part number since they are really close technology.
So my question is, you ordered ws2812b it seems from your manual and you said you checked they were the right led, you checked the ortie tation of the pad then? Since it seems to be the only different between the both (cf my article in the comments i think)


Sorry for the headache about this but it seems rather complicated to shop.
You can't simply look at the difference in price of the strip from adafruit and aliexpress

I've used BTF-lighting with success. I think that the results are also dictated that the moisture removal (baking) which I actually discussed with the led manufacturer we visited 2 weeks ago (that would easily explain the bad pixel / sharpie test).

The SK doesn't "replace". It's indeed cheaper reason why it's getting popular, has a different silicon / IC / controller with different timing and probably a different led too.

I haven't looked under a microscope each strip I got but I think I got each time what I've ordered. My default settings are made for WS28XX so when I get a SK I know because it doesn't work out of the box (timing need to be adjusted). I could tell by eye the difference between strips I got a year and 2 years ago (WS2811 or 2812 not B) by the pin number (easy) and by the shape of the led metal plates (inside the pixel).

Vendors I've used carry both chips, so I've been confident to get what I ordered, and that was the case.
