Finally GoPro! No tiny pin iPod connector, no 5v pre-amp, no crippled downgraded firmware, just the mic-in cable and an easy off the shelf adapter from the Peltor. The adapter was super easy to make, but I have these kind of parts laying around. 🙂 Look for a 3.5mm Stereo Plug to Mono RCA Jack along with an everyday RCA cable, and you’ll be up and running in minutes.
We’ll add the GoPro Frame mount for easy connection to the Hero3. The mic-in utilizes the USB connector and after an in-car test sounds great! Now our original Hero can go in his waterproof box + suction cup + tether for outside action shots!
EDIT: After posting this I tested 720P with both the Hero and Hero3 @ 60 frames per second. Checkout the handy chart I made for GoPro 720P. Notice the Hero3 grabs at twice the bandwidth, thus twice the recording space for the same time.
