Experimenting with a simple LASER pointer. The laser pointer is modulated by connecting an audio source to the primary side of a transformer. The secondary side is connected to the LASER pointer. The modulated light signal is received by a standard solar-cell and the signal is amplified by a small MP3 walkman audio amplifier. Sounds really good for such a simple installation!
