Having spent the last two years reading news about Russian-Ukrainian war it's pretty refreshing to see how many people still associate DJI drones with peaceful life and entertainment. And seeing a drone flying in the mountains my first thought was about Karabakh.

Genuine question: what kind of smartphone do you think the soldiers use? Do you associate Android/iOS to war? Pretty sure terrorists use Android/iOS, too.

Soldiers typically use tablets, to have larger screens. With Google Meet or Discord for real time streaming to battalion/brigade command.

Why would you single out SpaceX for this? Not only is that argument applicable to every single other launch provider on the planet, it is also applicable to almost every single factory and even city on the planet. How is the biodiversity in Los Angeles? How big are the areas affected by SpaceX launch facilities compared to the area affected by Los Angeles?

Furthermore, SpaceX's newest rocket burns methane. That means that it is creating a market for a potent greenhouse gas, that is often otherwise just vented to atmosphere as a byproduct of oil extraction. Burning methane creates carbon dioxide, which has 1/20 the climate impact of methane. That rocket, therefore, actually is a net benefit to reduce greenhouse warming.

Omg, finally, waypoints in an entry level drone! Shooting smooth footage by hand is hard, especially if you're planning to speed it up in editing. The camera improvements look nice too.

Streaming 1080p/60fps up to 20km wirelessly is mind boggling to me. What kind of tech is used to make that happen? seems like it'd require a lot of power.

Keep in mind that this only applies to the FCC regulations. In Europe (CE regulations) the claimed range is 10 km. The mini 3 pro has a CE regulations claimed range of 8 km, but after 2.5 km I pretty much loose connection. If I turn the drone to face my direction, I might be able to fly it a bit further, but at this point it is so hard to control it, that there is no point. Btw, according to regulations, you can not…

I always look at these and think I want one but also can't think of what i'd actually use it for. I just picture it sitting in a closet next to my GoPro and Oculus after about 3 days of messing around. Anyone own one? What do you use it for?

I have a Mini 3 Pro, and I’m quite happy with some of the videos I’ve made with it. Here’s my latest video: https://vimeo.com/860800214 And a couple more that I’m happy with: https://www.instagram.com/reel/CsMqtYXICju/?igshid=MWZjMTM2O... https://www.instagram.com/reel/Crss_afoG0a/?igshid=MWZjMTM2O...

Those are very nice shots, but... did you considered the local laws before flying them in city centers? From where I am (Spain) it's a big no no to fly one over any even sparsely populated area. It's forbidden (AKA requiring lots of permits) even if you are not flying over people (like in the Thames) or the drone is less than 250g.

> Even a sport watch can be a security threat as demo by some exercise army personnel. In the early days of the Afghan (or was it Iraq?) war, people used Strava to figure out the locations of American bases. They'd see a bunch of smart watches suddenly wake up in the morning and start exercising at the same time, a dead giveaway.

Neither. The US’ wars in both places predate general availability “smart” devices by quite some time. There were devices like black berries and tmobile sidekick, and gps trackers from garmin (etc) but I think the incidents you were referring to happened much later (2018 vs 2001/2002).

The issue with the watch is the data is publicly available (social aspect) and requires no effort on the other side to figure out.

The video quality degrades at longer distances. You can't get the full bandwidth at the maximum distance, but you might see enough to navigate. Communicating with a drone up in the sky is easier than something like your WiFi or your cell phone because you have a nice, clear line of sight to the drone. Fly behind a hill, building, or some trees at distance and the drone will lose connection and go into safety mode. Th…

Cool stuff. I suspect military communications uses wattage MUCH stronger than what's allowed by regulation in the battle space, correct?

Lower Frequencies, More power, more directionality, more digital signal Processing are the four ways to increase range.

Each has their own disadvantages and advantages, so it's always a tradeoff.

Whoever developed this website was probably told "We want it to look like Apple.com" and didn't veer one inch from that request. Not to say it looks bad, but it does feel unoriginal to me.

I came here and hit command-f "Apple" to see if others had the same opinion.

Funny, I hit /apple for the same reason.

I'd like to find a good competitor too, and not just because of the geofencing. DJI has been identified as a national security threat by the US DOD, essentially because there's no way to be sure that every second of GPS-tagged video shot by a DJI drone isn't going into a giant server farm owned by the Chinese intelligence service. https://www.defense.gov/News/Releases/Release/Article/270608...

> identified as a national security threat by the US DOD, essentially because there's no way to be sure that every second of GPS-tagged video shot by a DJI drone isn't going into a giant server farm owned by the Chinese intelligence service. There are far more obvious reasons for that. These drones are of enormous military value. By buying them, US consumers are funding an obvious foreign military hardware production…

Jammers don't have much effect because of the frequency hopping technology of 2.4ghz band used by hobbyist has been improved upon for years. We used to have flags and announce use frequency during the FM days, now we just go out and race without worrying about interference with other users.

Is there any system that works for at least 10-20km without line of sight, supporting a video feed usable for guidance, without cell phone network coverage? Maybe something where there are two drones, and one flies high with line of sight to both the user and the low-flying drone so that it can act as a relay like a satellite would? Or something that uses radio frequencies that bounce over the atmosphere, and if band…

why does this read like tech that should not be reasonably legalized for civilian use

Don't know about anywhere else but my local laws says you need to see the drone to operate it and you aren't allowed to control it in FPV mode.

Local law also say there are very little places I could really use it in 50km radius from home.
