What other lights can you listen to? Bicycle lights, light-up toys and flashing fairy lights all make amazing sounds!

How does it work?

Pulse Width Modulation

When photons of light hit the solar panel it creates electricity through the photovoltaic effect. The different sounds it creates are due to pulse-width modulation (PWM). This is what light emitting diodes (LEDs) use to change brightness. PMW is when LEDs turn off and on at different rates, which we then hear as different pitches when amplified through a speaker.

Side Chaining Light

When you have a flashing light next to a constant light on the Photon Smasher, the intensity of the flash cuts out the constant light creating amazing synthesiser rhythms – all made from light!

To do this you need a second light, bicycle lights are perfect – but anything that flashes strong enough should work – like a strobing flashlight.
