Is my NBv3 broken?

[Pyron]

Ok hi,

Two days ago i wired up my new NBv3. It was my first saber build and I was pretty proud when it actually worked. I played arround with the sound fonts and the sd card for a bit and everything worked fine. Then I put the saber next to my bed and went asleep. On the next day i tried to start my saber up but nothing happened. I looked at the wiring and everything looked fine. Then i re-wired everything but it still didn't work. I tried different batteries and battery packs until my speaker made a strange sound. Because the mp3 file is too big for an attachment i uploaded it to youtube: https://youtu.be/1zdRtebxf4k

I hope someone can help me I really don't know what to do now :(

Charge your batteries to full, then try again.

i feel really stupid now :/ You were right I seriously tested every battery pack that was empty that I had lying arround. I got some new Batteries and now it works thx :)

Strange sounds are the hallmark of a low battery. Glad its working.
