i ve build an Spoke POV Kit with orange LEDs which dosent work as it should.
My problem is this, when i put in both batteries one batterie on the other end oppsite where the atmel is.
Gets very hot, so ive checked the batterie holders and i noticed a short circuit between plus and minus.
I looked at the solder connections but without any brigdes or cold solder joints.
Everthing looks fine.
So then ive connected an external dc power to the J1 joint with 3 V and it worked as it should.
My big question is now why is there a short circuit and is there any board layout shematic so i can follow the traces.
Besides i think the big electrolytic capacitor is wrong installed maybe can anybody check is out.
I hope the pictures are helping, i would be happy for every idea.
Thanks a lot
