Listen to light with the Photon Smasher, the solar cell microphone that uncovers a secret soundscape of music and sound hidden in plain sight. The solar cell on the Photon Smasher is sensitive to wavelengths in the infrared and visible light parts of the electromagnetic spectrum. If you shine an LED at the Photon Smasher, you'll likely hear a single constant pitch. This is due to Pulse Width Modulation (PWM), a technique LEDs use to vary the perceived power going to an LED by quickly turning the power on and off. LEDs reduce their brightness by varying the duty cycle, the time spent on versus off. The rate of the PWM is directly linked to the pitch frequency heard when listening to LEDs with the Photon Smasher. *EU Customers* Please note due to Brexit, you may have to pay customs or VAT charges and a handling fee in your receiving country before you can claim the parcel. These charges will depend on your country and the total value of the order.
