Indoor testing

After calibrating two amplifier Version 4 boards and hooking them up to the microcontroller two new cases were built. Unintentionally they turned out to look like Minions, which is why I am tempted to call them just that.

The goal is to set them up over the next couple of days in a new field location. One will be connected to a douglas fir, the other one to a piece of dead wood as a control.
