Neopixel blade not lighting up

[TheSpaghettiJedi]

Ok, so I built a neopixel lightsaber, wired it up outside the hilt and it worked fine, but when I put it inside the hilt the LED's don't light up. I took it out and checked all the connectors and wires, they're fine, nothing is shorting so I'm stumped as to what the issue could be. Any idea's as to what the problem is? The wires did twist a fair bit when I tried to get it in the hilt. I'm using a NBV4 assembly, momentary switch, a 18650 panasonic battery (protected), the css neopixel adaptors and two WS2812B strips. The soundboard still works without the LED's plugged in so the board is fine to my knowledge. Any advice would be much appreciated

If memory serves the Panasonic 18650 can't supply the amps for a neopixel blade, if grab one of the 15A 18650s from the store and see if that gets it working. When you did the test, was it with one strip or both strips?

Are you still getting sound, or does it just crash dead?

Traditionally most 18650s have been protected at 3-5amps which is not sufficient for the pixel blade. It may or may not be related to the cell, but the protection circuit is what makes it cut out.

Actually, reading it again and not in a pre-caffinated state (i.e. just woke up), you noted that when the LEDs don't light up and you get sound without the blade in place. Does that mean you get completely dead electronics when the blade is in or do you get audio and no light?

No the sound still works even with the blade in place. And the manual reccomends using a panasonic battery which was why I got it. It was lighting up fine when I wired it up outside the hilt, it's when I put it in the hilt that it stopped working

how did you have it wired up when outside the hilt? were you using the quick disconnect or just connecting the wires to the board?
