Logging Power Consumption
i'm planning project using rasp pi , sleepypi shield: spi arduino tasked shutting down pi when it's not in use. since pi powerthirsty monster in project, doesn't need on time. specifically, pi booted, take photo, upload internet, , shut down. once hour or when there pir trigger.
when deploy project in field run off solar , either lipo or supercap. before decide , go buying , building power supply want power @ home while , simulate normal use conditions.
i need way of logging actual current consumption of project on time. during periods project might take 1-2 ma of draw, while @ other points might drawing 600-800 ma.
what effective way of logging that? preferably without buying extra, sophisticated parts.

use multimeter , have camera take picture of meter periodically. 
rather log current, there may other ways solve problem. 1 might measure current meter while project in various states. log state of project , infer current previous measurements. if looking find out energy usage current measurements, time how long project runs known supply of energy (battery, supercap).
