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.)

Optional:
 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.)

Additional Notes:
 The ceramic earphone can be replaced with a piezo transducer but that would NOT be an earpiece.

Step 2: Build the Solar Assembly


Take your solar panel(s) and wire them in series...skip this if you are using one. Solder two wires from the ends and you are done with the solar assembly.

Step 3: Build the Rest

Cut the headphone jack off (not necessary if female one is used.) Then solder the two wires (or leads) to the wires from the solar panel. Hot glue or using tape, secure them together.

Step 4: Amp it.

Attach a male to male headphone jack from the solar panel to the amp. Next where there is the headphone sign, plug in the male jack.

Hmmmm I bet you could use this to listen to the laser audio from my "MintyBeam" instructable !!

Strictly speaking you are not the first to listen to light...

In the early 1960s Bell Labs produced a science kit "from sun to sound" introducing experiments with solar-powered oscillators for headphones: http://www.porticus.org/bell/belllabs_kits_stos.html

I didn't even know people still looked at this. :-)

I made this ible BEFORE I read about that. I saw it in one of the engineer's mini notebooks.

Thanks , though.

Try listen to a tv remote control see if it produces sound

Have YOU tried it? If you want to know you should build one. I am not going to test it for you but, theoretically it should be a series of clicks...try looking at your remote via a camera...there is a lot more LIGHT that you yourself have not seen.

Nice job...but you used my idea.
This idea to listen to light has actually been around since the 1970's. I know a man who set up his stereo system over 25 years ago with IR transmitters and receivers. It played his music on speakers around the room using light. Fun stuff.

Maybe you could take the output from a music playing thing which normally goes to speakers, and instead hook it up to a light. Then when that light is shining on you solar cell you hear the song.

Actually, that is how I discovered this would work. If you happen to have a copy of Gonzo Gizmos or, seen www.scitoys.com then you would know what I mean. This idea of listening to music via light originated with Simon Quellen Field and was aired on one of the Weekend Projects with Kip Kay. Thanks for the feedback, though.
