Materials:

  1. Electret condenser microphone capsule
  2. Small metal or plastic clip-on collar attachment
  3. Shielded cable (thin and flexible)
  4. 3.5mm TRS audio jack
  5. Soldering iron and solder
  6. Heat shrink tubing
  7. Wire stripper
  8. Electrical tape

Steps:

  1. Prepare the Microphone Capsule:

    • Start by identifying the two leads of the electret condenser microphone capsule. Usually, one lead is longer than the other.
    • Solder the longer lead to the tip (T) of the 3.5mm TRS audio jack and the shorter lead to the ring (R) of the jack. If your microphone capsule has a ground lead, connect it to the sleeve (S) of the jack.

  2. Attach the Microphone to the Clip:

    • Use the clip-on collar attachment to secure the microphone capsule in a discreet location on your collar. You may need to modify the clip to accommodate the microphone's size.

  1. Prepare the Cable:

    • Cut a length of shielded cable that is long enough to reach from your collar to the recording device. Strip the ends of the cable to expose the inner wires.

  2. Connect the Cable to the Microphone:

    • Solder the wires from the shielded cable to the corresponding connections on the microphone capsule. Ensure a secure connection, and use heat shrink tubing or electrical tape to insulate the soldered joints.

  3. Secure the Cable:

    • Use clips or adhesive cable organizers to secure the cable along your clothing, making it inconspicuous.

  4. Connect the Cable to the Audio Jack:

    • Connect the other end of the shielded cable to the 3.5mm TRS audio jack. Solder the wires securely and use heat shrink tubing or electrical tape to insulate the connections.

  5. Test Your DIY Collar Microphone:

    • Plug the 3.5mm audio jack into a recording device, such as a smartphone, camera, or audio recorder. Test the microphone to ensure it's functioning properly.



Remember, this is a basic DIY approach, and the success of your DIY collar microphone will depend on the quality of components used and your soldering skills. If you're not familiar with soldering or electronics, it's a good idea to seek help from someone experienced or consider purchasing a pre-made collar microphone. Additionally, be mindful of any local regulations regarding recording conversations and respect others' privacy.
