Power Analyzer V2
Lastest version of the PowerAnalyzer augmented with current and power measurment.
The principal changes are:
- the addition of a current sensor
- the replacement of the voltage sensing transformer with a voltage sensing board
- the adoption of an industrial grade power supply unit
- a software upgrade to provide additional measurements

The resistors are actually 47K not 22K as shown in the circuit diagram (doh!). The 3.5mm jack on the right goes to LineIn on the Fe-Pi Audio Z V2 board (which performs the oscilloscope function).
