Directed High Frequency Open Air Communication

The Directed High Frequency Open Air Communication project sources an electrical audio signal from an auxiliary input and uses this signal to directly modulate a laser. This modulation causes the detector to generate a varying voltage level to be amplified at the receiver. The amplified signal is then used to drive a speaker. The device also aims to achieve manual beam tracking through the use of servo movement. A remote control will send a signal on the devices’ IR receiver and that data will to be used to manually control the servos. Manual control was also implemented through a joystick connected to the device.
