Built for Vloggers the GoPro Media Mod allows users to accessorize their GoPro with an external LCD and microphone. Code named "Borg" it finally shipped three months later than the original GoPro HERO8 release date. From our analysis, this delay was caused by the software lagging the hardware.  Features User configurable stereo audio input:   (Standard Mic, Standard Mic+, Powered Mic, Powered Mic+, Line In) Unidirectional built in microphones.

It's been a while since we performed a physical teardown of a GOPRO, but with the innovations in the new GOPRO MAX, a full teardown is warranted. This camera will allow you to get stabilized, immersive shots, with minimal post editing. Many other blogs have already reviewed the MAX's functionality, so we'll focus on the internal wizardry that makes it work. System's Components Housing The ABS plastic housing has a rubberized overmolding. It consists of two halves, sealed together by some sort of epoxy....

A quick summary of the design wins for the GoPro HERO8 (J-Bay). No significant electronic differences between the HERO7 and the HERO8. However small changes in hardware can make huge impacts on the system reliability and stabilization.  Updated IMU (inertial sensing) New power subsystem including yet unknown change to battery. This allows them to "boost" the processor / LDDR. The battery may have a higher discharge rate or temperature tolerance. (TBD) Faster MIMO enabled WiFi chipset Slimport driver for video over USB-C...

The DJI Osmo Action is taunted as the GoPro HERO7 Black killer so I had to purchase one and see how it compares. I am not sponsored by GoPro or DJI and have no skin in the game, so this is an unbiased review versus most of what you read on the internet. On it's release, I had only a few hours before a trip to put it through the ringer. At the consent of iFly Phx, I was able...

FOR SECURITY RESEARCH / Interoperability with our products.   Starting with the GoPro HERO5, the USB-C interface supports accessories such as a quick charger, a Mic adapter, and the Karma Drone/Grip. Briefly GoPro Inc. provided a developer program for access to this interface, but they soon dissolved that division as the company went south.  After some, (a lot), of research, we've found the developer program only allowed access to a subset of the Herobus™ 2.0 (HB) functionality. Although I haven't bought a third party...
