Renewed Microphone (change Audio Jack to Use With Pc)

Introduction: Renewed Microphone (change Audio Jack to Use With Pc)

A few days ago, I found an old microphone somewhere in my flat and I wanted to use it with my pc. The problem was that it had an old 3-pin DIN connector (wiki link: DIN connector) which of course didn't fit in the 3.5 TRS socket of my pc.
I didn't want to buy a new microphone so I  bought a single TRS 3-contact plug and soldered it to the microphone: Voila! it did work.
This Instructable shows you how I did that and how to do it on your own too.
I'm from Germany and this is my first Instructable so I apologize for any mistakes in grammar and spelling aswell as errors in the Instructable itself. Please tell me if you find any! Please comment!

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials and Tools Needed

You will need:

The microphone
a TRS connector mono or stereo (I bought it for about one euro, thats ~1.25 dollars)
Soldering Iron
Scissors (If you've got some other Tool to strip off the coating of the cable use it! I had to use the scissors... wasn't that easy^^)

Step 2: Cut Off the DIN Connector

Self explanatory... (use the scissors or the cutting function of your Pliers)

Step 3: Strip the Coating of the Cable

Carefully cut into the coating from all sides to separate a part of the coating from the rest of the cables coating, but be careful not to damage the copper wires underneath. Then strip off the coating by pushing the separated part towards the end of the cable.
Then, twirl the wires revealed and strip off only a part of the inner coating, to avoid contact of the two strands of wires. Again be careful not to damage the wires inside the coating. When you've done that, twirl these too.

Step 4: Connecting the Cable to the Plug

Screw open the plug and slide the plstic or metal hull on the cable.
Then stick the outer wires into the hole of connection 1 and secure the cable by clenching it into place between the two metal strips of connection 1. Then stick the inner wire through the holes of connection 2 and 3 (which is just behind connection 2 in this picture).

Step 5: Soldering the Connections

Take your soldering iron and the solder and solder the wire to the connections at the holes.
Then cut off any protruding parts of wire.

Step 6: Screw the Hull on the Plug and Enjoy!!

Screw the hull on the plug and plug your microphone into your pc. Yeah! record and enjoy you voice :D

    i wanna do this with an old karaoke mic which came bundled with a Sony Hi-Fi system my dad bought when i was 4. i already have a headset for voice chats and such but this old mic is much better for recording voice. i had doubts if the inside of the cable looks the same as this one, though. it has the instrument plug thing i forgot the name its this long ============== like my guitar cable. if you have any thoughts please do share :)

    this is awesome.. nice job my friend.. what am actually thinking is on adding a small mic to my headset directly.. i wonder if it will work the same

    can a TS connector be used instead because i see that you shorted 2 lead connection on the TRS connector


    Reply 9 years ago on Introduction

    definitely. And that would also make more sense since such a mic is mono :D I did that because i only had an trs connector. Shorting the connections for left and right gives the same signal on both connection when attached to for example a pc.

    Nice. Good to see vintage equipment revived. How does it sound compared to a modern electret mic?

    Thanks a lot! Well I would say it depends on the quality of the microphone, mine is quite good actually, clear sound and all, and although it isn't quite as loud as modern mics it functions very well!
