How could I measure current with a raspberry pi at voltages and currents that can be found inside a typical home's power outlets?
The goal is to create a device that monitors how much energy is being used through a particular outlet.

Radioshack sells a VOM that has a serial port and a API to interact with the meter.
You could get a "premade" device such as this if it has a customizable API.
Then just code a pi interface to it.
