    Laser Audio Transceiver with LM386 audio amp

    sorry for 1year late reply but if ur still there.. yes it was working back when i made it. not sure where it is now though. able to plug in my phone and play some music, and the laser beam would change according to the audio signal. and the receiving end would be able to receive the laser, and be able to hear the music aft some tuning.
