FM Receiver From Old Dead Headphones
Intro: FM Receiver From Old Dead Headphones
Have you ever wanted to listen to the radio while you exercise or just walking but also wanted not to wear headphones? This instructable will show you an easy way of transforming your dead headphones into a tiny fm receiver.
STEP 1: The Materials and Tools
You will only need an old pair of headphones and a pair of scissors
STEP 2: Cut the Headphone Cord
Now it is your choice where you want to cut the cord. Just be sure that there is some cord left before the headphone jack so as to be sure that there won't be any problem with the signal.
STEP 3: The End
Now you have got rid of the "Plug-In Your Earphones" error. This transmitter can be used with any device that has fm and can output from speakers

Iphone uses a FOUR connector jack, where as normal headphones use a 3-connector.

You'll have the same problem using the jack from some of the older wired cell-phone headsets.
Basically, you end up either NOT making contact, or making overlapping contact, inside the jack...
Likewise, if you try to use normal headphones on an iphone/ipod... you'll end up with sound out of one ear only, usually.

This is partially because it uses the headphone cord to act as a secondary FM antenna(the cellular antenna is the "primary" but is low gain, because of the size, and the fact that FM is on the very edge of the frequency range it was designed to receive)
I WOULD suggest a longer length of cord though. The longer the dangle, the better the reception... up to 0.92 meters in length(for 101.9FM).
That's the 5/8ths wavelength measure... optimal for FM reception.
