Anyone been able to decode DJI Mavic air flight logs, exported using Assistant 2? Files compressed with zlib. Decompression shows some plain text, but a lot of random symbols etc

I work for an insurance company that's trying to keep adjusters from falling off of buildings by looking at the feasibility of using drones to map roof claims. As a proof of concept, my boss bought a $1500 DJI Phantom 4 Pro. He's asked me to look into building drones as a feasible way to keep costs down. I've been researching it, but I keep coming against conflicting data. I was looking at using the following list as a preliminary build, and kept seeing people who have a similar build saying that everything works great and that it flies beautifully. But when I run the math (using a SWAG for the mass of some of the items), it's a bumblebee. It's too heavy to fly, it will only fly for maybe 6-8 minutes, etc. I'll grant that I'm looking at doing some things that probably haven't really been done as much in home builds of aerial photography drones, but I need to beat a Phantom 4 in price and ability if possible, which is no mean feat.

According to an article on Forbes the information loaded into the FAA drone registry database will be searchable by the public. Yet another reason to not register your multirotor with the FAA. As many have pointed out, even Darren on Threatwire, if anyone has your registration number they can simply affix it to their multirotor and perform nefarious acts leading the authorities straight to you. It's becoming more obvious by the day just how little thought was put into this program.

Students and researchers from Rutgers University built a quadcopter that flies and swims! This technology is pretty cool and would probably make people feel more calm when flying over water.

You may remember my last project where I upgraded a few components on my DJI FlameWheel F450. I didn't really know a whole lot about multirotors then as I simply bought pieces to a very common build and followed a video to put them together. Now, after much research, I have a little more knowledge about how all of the components work. For my next build I've decided to go with the HK Alien 560 frame as I want something I can fold up and easily place in a bag. The components I will use are: APM 2.6+ Autopilot 3DR uBlox GPS with Compass RX701 7CH Receiver HK Alien 560 Carbon Fiber Folding Afro ESC 30A x4 Turnigy Multistar 2814-700kV motors x4 I still don't know which props I will use. I was hoping to use my extra set of Graupner 10x5 eprops but this frame requires 11"-12" props. So far I have purchased the frame, ESCs, and 7CH receiver. Since I have no use for the receiver yet I figured I would use it in another project. One of my buddies recently bought a small chassis and SainSmart motor shield to build a car that could be controlled through his Arduino Uno. All of my Arduino experience in the past has been on the networking and LED side as you guys may remember this messaging project. So I figured I could learn something about controlling motors with Arduino and helped him build it. After seeing how simple it was I bought my own kit and figured I would try to get it to work with my DEVO7 and the new receiver for my HK Alien 560. This morning I got it to work but it can only use one channel from the transmitter because the motor shield uses digital pin 3 for motor 2. Digital pins 2 and 3 are the only hardware interrupts on the Uno which are used for receiving signals from different channels. I used the following library to receive input from the TX/RX (https://github.com/helscream/RC_Rx_Arduino_Mega/tree/master/RC_Rx_header_example). This library was developed for the Mega which has 6 hardware interrupt pins. I've been thinking about building an incredibly crude quadcopter with an Arduino and now I realize the Mega is the only way to do this properly because you need at least 4 channels for full control (pitch, roll, yaw, throttle). Oh yeah, for power I'm using my Pineapple Juice 6800, lol. The kit came with a 4 AA battery holder but that only provides 6V causing the car to move way too slow. Once I added the 12V Pineapple Juice pack it started running a lot faster. Anyway here is my code using the rc_rx and AFMotor libraries: And here is a video: I'll make sure to keep this thread updated as I move forward with my HK Alien 560 build.

Hey Hak5 community, I am selling a DJI S900 Hexacopter with most of the equipment needed to do professional aerial photography or just to fly for fun. Comes with a Pelican 0370 case with foam and a bunch of extras Setup with a Zenmuse Gimbal for the Sony Nex5 Has FPV Equipment and ready to fly with two 16,000mah batteries. This would make a monster pentesting platform to carry lots of hacker gear Let me know if your interested.

Hi, Does anyone have any experience with these? I have been told that it's a good idea to get a cheaper ~$50 one to practice my piloting. I expect that I will probably be terrible and crash it often. Is it as fun as I imagine it will be?

Here in Balkans everything is politics, even DRONES! :) I guess stunts like this will get drones banned really soon. :( https://www.youtube.com/watch?v=hJSQf737Agw And for some more context:

Not sure how I missed this one. Looks pretty neat, and supposed to get up to 20 minutes of flight time even with a GoPro attached, but can hold other payloads. GPS waypoints, and follow me mode sounds pretty cool as well. Was a kickstarted, and they claim to have made it hackable, but does not look open source like our friends. Great ideas, even with the FAA crackdown it will be interesting to see what this all goes. https://www.thepocketdrone.com/store/checkout?cart=53fac793285fd

I was looking on reddit and found little tidbit. I wonder if they head about the pineapple and got the same idea that darren and the gang did. http://money.cnn.com/2014/03/20/technology/security/drone-phone/

OK, so I just found a new reason to try to unbrick my Mark IV and flash it. On another hacking website they had an article about some $350 drone with a WiFi radio. Last year someone gave me one of those little drone helicopters you can fly with your smartphone. It only cost like $79 at Radio Shack (you can probably beat this deal) and it comes with a replacement plan. I'm thinking we should strap try strapping a Mk 4+battery pack on to a drone and do some "Wi-Flying". No more walking right into the lion's den looking all awkward as you clumsily try to plug-in and/or hide your strange-looking device with the antenna and all that. Just get within eyesight -- or within radio signal distance if you have a camera on your drone -- and fly it into enemy territory, capturing data all the while. If you got good with it then you could fly it up the side of a tall building and land on a windowsill, capture some packets for an hour and fly it back down! :) OK I completely realize that this probably has limited sane usefulness for us and the windowsill part may be a bit on the optimistic side, but wouldn't it be cool to help pioneer the capability? Has anyone here done it and if so is there any video, because I'd love to see it? I could totally see the FBI and CIA lurking around reading about this, then deciding to rip us off and make a $500,000 version LOL
