I have just completed my rebuild of The Groundhog hexacopter with a Pixhawk2 and NVIDIA Jetson TX2 companion computer. This is in preparation for the coding blogs I am posting and further work integrating depth cameras and machine learning. For those interested, details of the build are posted on my blog at www.mikeisted.com.

Wow, How about your progress now?
@Lyn Rees - for info Lyn we have just put together a co-axial quad which will also have the Jetson on-board, multiple cameras and the rest. I'll let you know how we get on!
Yes, the J120 carrier board is excellent and benefits from 2 USB3 ports, unlike the TX2 development board. Good luck!
I'm also waiting for my carrier board to arrive !!!

That's a lovely thought, but I guess the kit I'm using is fairly readily available - what I'm trying to do is to help others 'glue' it together in a useful way!
Mike, I enjoy following your blog. You should definitely put up the kit for sale as a bundle ;-)
The co-ax IMHO has all the advantages of an octo (I have a 1000mm one of those as well that I will,hopefully, get around to finishing some day) and no disadvantage for the reasons mentioned above. It also the ability to use larger props for a given frame size. I designed my own co-ax following known principals (i'm no expert) as this came about following a crash and subsequent fire with my first quad. I do use Linkedin at work but not at home at this time.
Very nice Lyn. I'm working towards a heavy lift octacopter, but could still be persuaded to go 4+4...
I have whole bunch of questions, but maybe this is going even more off-piste. You on LinkedIn?
The cool thing with the co-ax is I can drive the motors 4 + 4 so the main supply powers (2 x 10'000, 6S) never meet. The multi copter has a better than 2.2:1 power to weight ratio. In this way I can afford to lose an entire side (4 motor / prop combinations) without loosing the copter (control is compromised quite heavily if all 4 shut down however). The secondary feeds (12V, 5.3V etc) from both custom power boards are protected via an "ideal diode". In this way I can dual feed any item without worrying about one supply taking out the other in the event of a failure!
