Energy Harvester Circuit

See our other Circuits.

This circuit will harvest energy from any small source such as a piezo electric buzzer element, speaker, solar cell.  It saves the energy to a 0.47 supper cap and boosts it to 3.3V using the Maxim chip.  The diode bridge is composted of low forward voltage BAT54 diodes.  The Max1675 has a quiescent current of less than 16uA. The zener protects the cap from over voltage.
