Neopixel stopped working

[Ezra__Knight]

I finished my first neopixel blade last night. Everything was working perfectly. Played around with it for a while, let it charge, played around some more on R.I.C.E and then let it charge over night with the smart charger. This morning I gave the blade a light sanding, put the blade in the saber, and there was no illumination. Hilt side was fine, all the right sounds and no distortions, just no light in the blade. I’m using a 15a battery, so I know it’s not the battery. I quadruple checked all my wiring before locking everything down. It worked perfectly yesterday and now there’s nothing. Any help or ideas would be greatly appreciated

Hey Ezra_Knight

Just to clarify; are you using the 7pin/11pin pcb boards like the store sells or is it a “Hardwired” blade?

When you say you checked your wiring; did that included that tiny little on-board resistor for the blade-side pcb?

I’m sure FJK, Tom Tilmon, or jbkuma will chime in; they are the neopixel triumvirate around here IMHO

I’d redownload and reinstallation the stock configurations (pre - “playing around with it”), to make sure you didn’t do something in RICE, which it sounds like you might have.

Well, that would make sense, but it continued to work even after R.I.C.E. I forgot to mention that I played with it for about 10-15 mins after I unhooked it from R.I.C.E. Everything was still perfect until I tried turning it on this morning

This may be a dumb suggestion, but on my saber, where I drilled my blade retention screw, i didn't sand the inside of the blade holder enough and although it felt like I had the blade pushed in, it actually wasn't all the way pressed against the pins.

Hey Ezra_Knight. Any luck getting it back up and running?

Have you tried FJK & Light Bringer’s suggestions?

While you may be correct; it is starting to sound more & more like a battery issue. The fact that it was working and then mysteriously doesn’t work after sitting overnight.

Maybe something mis-wired associated with the kill key that isn’t cutting the power completely when its inserted?

What are the specs on your battery and charger? (If its an el-cheapo / aliexpress battery it may not be up to snuff regardless of how it is labelled.)

The Neopixel Pin connectors weren’t in there when this all happened, were they?

I used an 11 pin pcb and I included the onboard resistor when I was doing all the wiring checks.
