I often work on live sporting events for tv and am looking to build a sound/video sync checker for use in the field, sometimes under very bright skies like in India. The design would be say up to 8 bright white LED's arranged in a circle on each face of a square box. The complete rotation cycle perhaps varies between 2-5 seconds with each LED turning on and off in turn. The 4 sets of LEDs driven from the same oscillator. When the '12 o'clock' LED is illuminated, an audio pulse is triggered for the duration of the LED illumination and heard through an inbuilt loudspeaker with perhaps a line level direct output via an appropriate connector. The audio signal/sample should have a steep initial transient akin to two bits of wood being hit!
The reason for having the LEDs on 4 sides is that it is useful to check the individual camera/recording/playback paths all in one go.
Any help with the circuit design would be much appreciated. Many thanks.
