For senior day sp. '06 i used the electronics class and avionics class to create the "apocalypse now" simulation to assist in student enrollment. I used the airframe of a Hughes 500 Helicopter same as was used in the film.
Voltage Conversion:
The helicopter used a 24VDC battery so i had the electronic student make a "converter" 24VDC to 12VDC to operate the audio amp.
Voltage conversion part II:
The second conversion is a 24VDC to 4.5VDC converter to power the CD player. The PLAY/PAUSE button was paralleled to a N.O. SPST switch in the instrument panel.
