Frank,

Looks like things are coming along nicely. Sure you were rushing and made a few mistakes. We have all done that. It is the desire to see your project come to life that prompts us towards a little haste from time to time.

On you dual MOSFETs, are those SOT563/SOT666/SSMINI6 packages? Those things are almost impossible to solder. I had to swap those out for some SOT363 parts which were still tricky, but way easier than the SOT666.

Good luck on your layout reworks.

Gene

This photo shows the impact of the interferences:

The slight *** is caused by the button being to close to the case. The interference between the buzzer and USB keeps the PCBs from sliding all the way without forcing. It may not look like much but will require a new layout to fix.
