DIY Cassette Tape to MP3 Aux Converter





Introduction: DIY Cassette Tape to MP3 Aux Converter

In this project we're gona transform an old cassete tape to high quallity MP3 Aux converter. Better to watch the video for FULL TUTORIAL.

Step 1: Disassembling the Radio

-First, seperate the speakers from the body and unsrew all screws that are holding the body together. My cassete motor didnt work so i just brake front plexi and the frame who is holding the tape in place

-Now we need to get this cassete magnetic heads which will transform our music signals to magnetic wavesS

-Just unscrew two swrews that are holding the head in place and cut the wires from the head becouse we will add a new one.

-This magnetic head has small piece of metal that we dont need so take it of with the pilers.

Step 2: Soldering and Wiring

-Unsolder left over wires from the head and find a suitable

cable with minimum of 3 wires inside

-Remove the isolation from the ends, put some solder on them and repeate the same proces on the other side as well. I used 3.5 mm metal jack which i get for about 1 euro. Plastic jack are three times cheaper but metal jacks looks more awsome

- Put some heatring tubes on the connections but if you dont have them use electric tape instead

- Two smaller pins are positive left and right channel and bigger pin is ground

- Fastst way to heat the tubes is to use a lighter and try not to burn them to much

- There will be three connections on the magnetic head. One that stands alone is ground and the others are left and right

- You can use another black heatring tube but i didnt have one so i used black electric tape to make all nicer and the cable is finished

Step 3: Modifying Cassette

- Now we need to modify our cassette tape

- Remove 5 small screws from the cassette

- Good trick is to use neodimium magnet to hold our screws together

- We need to cut off the middle frame for the screw and to that just take soldering iron and melt down the plastic untill it looks fine

- I used hot glue gun to secure the magnetic head to the cassete

- Drill a hole or melt down the plastic at the side of the cassette so the cable can go throught

- Screw back 4 screws and you are ready to test our finished product

    Where do you find a thinker wire like that? With three inside--what type of electronics have this? Or where do you get wire with wire inside?

    Soldering Iron
    Heat Shrink Tubing (or electrical tape)
    Wire Strippers
    Razor Blade
    Destroy-able Cassette Player

    Can i get a list of the needed supplies for this project? I'm having trouble understanding a few things with the accent.

    Thanks :)

    So thats how those work! Nice Work!

    what is the background music ??

    This may not work in some later cassette decks. My 96 Toyota Camry sensed the speed of rotation of the reels and if it sensed anything that it wasn't expecting, it totally shut down and didn't even try to read the tape. Most aux to tape converters didn't work because of that. I actually had to gut a tape, make a pulley system inside with a rubber band belt, and solder six inputs directly to the board inside the stereo and even that was less than reliable.
    But that was just something I ran into. I'm sure most decks don't have this problem.

    I expect that you could work around that by not removing the magnetic tape and simply adding a freely spinning wheel that the tape can move across that also keeps it away from it's normal position so there's room for the magnetic head.

    That could work, but the stereo would stop at the end of the tape. At the very least it would pause then start in the other direction if it has an auto reverse play feature.

    Ugh! MP3 is last decade tech... I think anyone with an inkling of appreciation for audio quality would be using FLAC or at least AAC to compromize file size for quality!

    If cassette tape 'hiss' wasn't bad enough, you're adding MP3 'ringing' to that complex white noise. At least the cassette hiss has a natural decay to it's complex frequency components! This is a good way to make MP3's nasty artifacts most noticeable!
