Yeah we got 220v in Italy and so it's wrote on the solderer... btw the diode was hot, also the plastic part was hot. I don't know now, it seems broken, when I shake it there something loose in it, I'll try to dismantle it and see what's wrong..
ok, i think that's unusual, I plugged it again and another sparks came out... is it normal?
Here a photo, I'm really sorry for the quality but I'm using the cellphone.
The soldere turned all brown and tarnished like it was burned.
well, soldering is pretty hard, the solder melts but the diodes ends doesnt keep the blob, it solidify on its own, also I got a spark from the solderer basis, don't know if it's broken or it'll explode or else
