A solar flare erupts from the surface of our Sun. The solar flare is observed by The Solar & Heliospheric Observatory (SOHO – a NASA/ESA spacecraft), the strength of the flare is transmitted to Earth and broadcast via a NASA website, a laptop monitors the website, the laptop communicates with a microcontroller, the microcontroller trips a relay, the relay connects a car battery to a coil of nichrome wire inside a borosilicate glass tube.
The result is a tone.
