Computer-processor controlled energy harvester system optimized for use on mobile platforms. The system uses a plurality of oscillating weight type energy collectors, each configured to store the energy from changes in the system's ambient acceleration as stored mechanical energy. The energy collectors are configured to move between a first position where the energy collector stores energy, to a second position where the energy collectors release stored energy to a geared electrical generator shaft, thus producing electrical energy, often stored in a battery. A plurality of processor controlled electronic actuators control when each energy collector stores and releases energy. The processor can use battery charge sensors, and suitable software and firmware to optimize system function. To facilitate use on mobile platforms, the processor also uses input from a 3-axis accelerometer to dynamically reconfigure the energy collectors according to the present major directions of ambient acceleration.
