Early November SeventhDwarf shared his Littlebits voltage and power monitor with us, built from an existing USB power monitor and fully integrated in the Littlebits system with bitsnaps.
Thanks SeventhDwarf for this exellent idea!
See his original project:
I wanted to make the same power meter but could not purchase the same USB gadget that was used...
So I used another type of meter with a 4 digit 7-segment display, showing the connected voltage and used current with an interval of a few seconds.
Duration: 10 hrs.
Remove both USB connections and replace them by wires, red for VCC and black for GND. he USB connectors have four pins, the outer ones are for the VCC and GND connections, the inner two are for the data connections, they are not used here. Remember which connection is for the incoming power.

The finished meter.
