The GoPro HD Hero 3 series cams are performing excellent in many aspects, except battery lifetime. At least for surface use I've come across something that helps in those cases where you drained all your spare Hero batteries and still want to shot more footage: a comparably small USB battery tank with quite some capacity. It is perfect to give your GoPro HD Heros some more juice, as well as to your mobile phone.
New pictures of me diving the Dräger Panorama Nova Dive full face mask ... I've now dived the Dräger in 50+ dives in open water, without even the slightest problem. I'm glad, I've purchased this full face mask, as it is a professional and rock-solid mask.
The plashy weather left room for improvement, yet our dive trip to the southern foothills of Harz was worth it. The two lakes Sundhäuser See and Möwensee are pleasant to dive, it's easy going in comparably clean waters. This year we had an incredible amount of tiny young crabs floating in the waters, looking like «snow» in the video footage. The perches were rather bored these days, hang around everywhere and sometimes even remotely glad for some fun they had with us divers ... but then it became booooring again fast.
Every electronic nowadays seem to come with USB connectivity. So the DJI Phantom quadcopter doesn't want to be the only exception. Using a USB cable you can update the quadcopter's firmware and tune several parameters of it's flight control unit. Easy, just install the driver software as well as the Naza-M assistent software (grrrr, Windows only). According to the manual, I powered up the Phantom, then connected the USB cable that came with the Phantom to my computer. Beep, beep, Windows recognizes the new USB device ... so I'm starting the assistent software ... and then nothing happens...
