When the GoPro HERO2 was released, it included an external microphone jack built in. It was a 3.5mm jack on the side to plug a small condenser mic into. The HERO3 also includes an external mic jack, however it is in the form of a multi use USB port. The user needs to supply a USB to 3.5mm converter cable to use an external microphone. This cable makes it hard for mic users to aim directional or stereo mics effectively without the use of another hand. The following Instructable teaches you how to build a simple rig which allows for the mounting of a microphone to the HERO3.
Step 1: Materials and Tools You'll Need:
The camera equipment I used in this project :
-GoPro "Skeleton Housing" for the HERO3 (To allow access to the USB ports on the camera)
-Olympus ME-51S Stereo Microphone
-GoPro 3.5mm Mic Adapter for HERO cameras (The one I used is exactly 5-1/4-inches long. If the length of yours differs, you may need to adjust the length of the CPVC cable-holding arm for your version of this project.)
-GoPro Tripod Mount
To Build the Mount:
-1/2" CPVC - For the frame. You wont need more than 15-inches in length.
-1/2" CPVC Elbow Fitting
-Machine Screws (1) 1/4 x 20 - about 1-1/2 to 2 inches long, for the tripod screw.
-Tripod Head/Plate (1) - You can use your favorite tripod's head plate, for the purposes of this project I used a small GorillaPod from JOBY.
-Washers (2) - I used 5/8" external diameter x 3/8" internal diameter but anything that fits the machine screw should work.
-Foam - (memory foam, egg crate, packing foam), Just a small piece to keep the microphone from rubbing the plastic.
-Welder cement or PVC/CPVC Cement - Any good heavy duty stuff will keep it together.
-Spray Paint - I used black. Camera equipment looks good in black!
-Dremel with a router bit, cutter bit and sander bit
-Drill with 1/4" bit
-Saw and miter
