 +This gallery shows some pictures of bad solderings - they should prevent you from making the same errors (feel free to add even more pictures here!)
 +
 +1: The core module has some badly soldered connections(loose),​ which could lead to failures. There are also missing solderings (e.g. 33pF cap below crystal). It makes sense to solder each pad again, the [[Soldering]] guide in the Wiki gives some useful tips\\
 +2: The legs of the caps should be cut, otherwise they can cause a short circuit which can damage the PIC!\\

 +
 +3: This seems to be a bad ground connection directly at the 78xx - it can lead to the wrong voltage. Here the same: just solder the pads again, it will help\\
 +And same as above: the long cap legs need to be cut, the danger of shorting out is too high!\\
