Keri sent me one of the early Rotorpixel Gimbal Lite prototypes, which I promptly attached to my DJI Phantom quadcopter and sent into the air, holding a GoPro HERO3 Black camera. The gimbal controllers and motors are being powered by Phantom’s auxiliary power cable (with JST connectors soldered on).

Rotorpixel Gimbal Lite prototype on a DJI Phantom quadcopter. Verdict: it works very well. It is incredible to have such stable video platform from such a small platform. On a Turnigy Nano-Tech 2200MAh 45-90C LiPo battery, I got just over 6 minutes of flight time (no crazy stunts). This isn’t great, for flight time, but the ...

I attached a GoPro HERO 3 to the frame using a velcro strap and did a few nervous flips with it—nervous, because the quad was really heavy. I was using a 2200MAh 3S battery which, combined with the GoPro, seems to ...

I’ve been reading for a long time that the DJI Phantom is “less stable” with 9" props than it is with 8" props. Today, I finally managed to get a set of 9" x 4.7" Gemfan carbon-fiber props onto my Phantom, which I attached securely by using a M6 lock nut and a M8 washer. I used a metric ...

[vimeo 64937816 w=250 h=141] With 9" x 4.7" Gemfan carbon-fiber props, the Phantom has plenty of lift and easily accelerates upward while hauling a GoPro HERO 3 camera, 2-axis gimbal, FPV transmitter and antenna,  and chopstick landing gear extensions. I flew around for 8.5 minutes, which is about 1 minute longer than I get when flying ...

Ray of No Mo Jello wire isolation mounts sent me a new (larger-than-usual) isolation mount to use on my DJI Phantom quadcopter in conjunction with a quadframe.com 2-axis gimbal. I ended up getting them to work together, but not using the standard GoPro mounting holes on the DJI Phantom frame. The problem with mounting gimbals using the two default screw ...

I went to the first SF Drones Startup Meetup tonight, which was hosted at NextSpace in downtown San Francisco and organized by Bryan Galusha. There was a fantastic turnout and the following interesting presentations: Robert Seidl talked about the (incredible) real-time video processing software developed by one of his companies, Realtime Video Systems. Bryan Galusha demoed Fighting Walrus Radio​, ...
