Hello,

I recently soldered up a Nano Bisc V4 to make sure everything is wired correctly. On the first power on, everything worked fine (power up sound when removing kill key, and LED+sound when activated) for a few seconds before it suddenly shut off.

Now, every time I remove the kill key and activate the saber, the LED turns on, increases in brightness for a couple of seconds, and then the speaker makes some crackling pop noise and the LED turns off. I'm guessing I may have somehow shorted something, but I don't know what.

Thank you,
