    Hello,

    How about a voice modulator?
    You can talk like a robot or donald duck with it.

    Hello,

    What do you mean with AUX MIC?
    You could try to get some small electret mic, those cost hardly anything.

    If you have some sort of microprocessor, you should make an LED grid that you can write programs for.

    Hello,

    A voice modulator consists of the following parts:
    An amplifier, to amplify the input signal from the mic.
    An oscillator, this can be made with a NE555 or the 4093.
    A chopper, this chops the audio signal (modulates), you can use the 4066 for it.
    An output amplifier, to amplify the chopped signal.

    Greetings,
    Bertus
