Please remove it then turn on 180 degrees and install back. Or better
use new one because it possible has been burned.

To be sure you can check pinout of BC337 here:

Who have more 1 euro coin stst to compare oxygeno07 device results?
I hope I will have my own stat soon.

[geminis74]

yes, I guess you're right, then black has made the same mistake, by the way that speaker (ohms) is recommended, thanks.
PS: tomorrow I prove and published results.

These links are not among the good unless they are connected to ground

[cordius]

why not? the full zone are non connected, are isolated to the track
excuse my english.

Hi Cordius,

I think what lari is saying is that you have flooded the board with an isolated net instead of ground. Looking at your image it seems he is correct. When performing a copper pour it should be associated with ground (0V) and you should remove all the isolated islands. However, I would think that your board will be ok as a prototype.

[cordius]

the copper area is isolated to the track 0,5 mm space.
