The main goal of the project is to develop a lock which does not require a continuous power supply.
Electric power is transmitted wirelessly between two coils that operate in a resonant mode.
User can unlock this strongbox using a wireless power transmitter and a secret code transmitter that operates in the 433 MHz licence free ISM band.
Receivers are installed inside the strongbox. A basic stamp microcontroller controls the lock through a servomotor.
