Modifying an old portable radio-cassette , so that it will play (loud) with any MP3 unit or ipod.
Basic soldering skills recommended, minimal list of parts.
By using a ziplock bag, you make your ipod or MP3 player splashproof , so you can listen to it while in the shower.
Step 1: Headphone cables
Take a pair of old headphones, cut away the headphones and strip the cables.
Use a cutter, but be very careful not to slice the cable.
Most of us have cheap earphones that were given to us by an airline.
I use these as the cable is relatively thick and easy to strip.
You only need the plug and 50 cm of wire.
Alternatively you can buy a plug and wire.
Step 2: Open the radio-cassette
With a Phillips screw driver open carefully the radio-cassette.
Keep all the screw, and (if possible) remember where they came from.
Step 3: Recording head
Locate the recording head.
There are 3 wires connected to it.
One white, one red and a ground.
Solder them off, or cut them off.
Step 4: Disconnect the motor
Cut off the wires of the motor of the cassette-player, you won't need it anymore.
The player will be quiter without the motor hiss.
Insulate the wires you cut off.
Step 5: Connect the wires & test
Solder the wires coming to the recording head to the wires of your plug.
Of course white to white. Red to red. Ground to ground.
Test the whole setup to see if it works, then insulate them well.
Step 6: Make a holder for the ipod or MP3
Not necessary, but it is nice to make a holder.
Use a plastic box to hold your MP3 player or ipod in place, so it won't slip.
You can even splashproof it with a ziplock.
Step 7: Listen to the music
Turn on your cassette-player on "cassette"
Use a low volume setting on your MP3 or ipod, otherwise you'll have distorted sound.
