There has been the Ghost Whisperer and the dragon whisperer (How To Train Your Dragon) but has there ever been a LIGHT LISTENER??? With one earbud and a solar panel YOU can become the world's FIRST Light Listener!
(Some restrictions apply. You will NOT be the world's first Light Listener because I will:)
Step 1: Get the Parts
You will need:
Ceramic earphone (I got mine at Mouser along with a lot of other great parts.)
Solar Panel(s) (You can use one or two...I used two because it gave me more surface area. More surface area = more noise!)
Tape or a hot glue gun (I used an abundance of tape for speed but, hot glue will work too.)
Wire (Stranded OR solid core works.)
Amplifier (Yes, you still need the earpiece)
Female 3.5mm (or 2.5mm) female headphone jack (This is if you have a male headphone jack on your earphone and don't want to cut it or if you want to plug it into an amplifier.)
The ceramic earphone can be replaced with a piezo transducer but that would NOT be an earpiece.
