Helmets are a requirement for scooters and bike riders and for people who resort to do-it-yourself means, here is one that can add a little lust to the whole helmet customization era. You can make a helmet that has a Bluetooth integrated with it.

The detailed steps for such a product (and the gallery images of the project):

  1. Find the set of Helmet speakers and microphone for your motorcycle helmet. Leon has used HS100T from IMC, which are inexpensive, provide loud volume and work great in combo with WayPoint Blue-Talk Wireless Bluetooth Headset.
  2. The materials Leon used are: Screwdriver, duct tape, markers and a sharp multi-purpose knife.
  3. Determine the location to place the speakers by placing them inside while wearing the helmet. Afterwards, mark the exact place using a white marker.
  4. Take out the inside lining…neatly, so it could be placed back correctly. It may be fastened with tape, buttons or other ways, to make it come out conveniently.
  5. Make a small dummy out of paper for the speaker and then use it to draw out the speaker area on the polystyrene core of the helmet.
  6. Cut a fine area to make sure the speaker fits it snug.
  7. Attach the speakers with durable tape. Note: make sure not to cover the speaker holes.
  8. Determine where you want to add the Bluetooth device. If it is small enough, it could easily be added in the polystyrene foam layer in the back of the helmet - Outline it with a white marker.
  9. Carve out the area and fit the BT device.
  10. The polystyrene chin piece of the helmet can usually be removed easily. Decide the are which the microphone could easily be attached which would also make it efficient and comfortable.
  11. In this specific case, the connector wire was too long, so it was cut, shortened and attached back together to finalize the entire Bluetooth Helmet.
