DIY GoPro Hero 3 Mini-USB External Microphone Cable (No housing modification required)

This video shows my custom-made mini-USB external microphone cable for the GoPro Hero 3. This cable can be used with the closed and opened (diving) housing - no modification of the housing is required. For means of comparison the audio quality is compared in four scenarios: internal microphone with/without housing, external microphone with original GoPro cable and custom DIY cable, and audio recorded with a TASCAM audio recorder. The external microphone used is an Edutige ETM-001: http://s.meh.at/edutige The audio sample is from this video: https://www.youtube.com/watch?v=4e_kz79tjb8 Special mini-USB charging cable for the GoPro Hero 3 diving housing: http://www.tequnique.com/goprocables Mini USB PIN layout of the GoPro Hero 3: http://img577.imageshack.us/img577/7678/hd310pinusbstecker2.jpg GoPro Hero Camera: http://goo.gl/fazFzW
