Quadcopter – techbloggingfool.com

I’ve had a DJI Mavic Air for years. I still get the little craft out from time to time. It’s fun to fly, and the AI keeps my rusty piloting skills from reeking too much havoc when I do.

The Mavic Air is an older drone but is still viable with a 4k camera and its 3-axis gimble.

I also have the first generation of XREAL’S AIR glasses. Another gadget I’ve gotten a lot of use out of. I started working on using them as first-person pilot goggles the day I unboxed them. The challenge has been that both my drone’s remote and the XREAL Air glasses need to connect to my phone via USB-C. Like most phones, mine only has one port.

I prefer AR glasses over external monitors for getting extra screen real-estate when I need it.

There are such things as USB-C splitters. Apparently, it should be technically possible to split the USB-C port with the correct cables and adapters. All of the adapters I found online were for power on one side and signal on the other. Or they were true splitters like the one below in which only one connection could be active at a time. The goggles idea would need both power and signal on both channels to work simeltaneously. If you know of something that works, please tell us in the comment section.

I tried several USB-C “Splitters” but was unable to get any of them to work.

Enter the XREAL BEAM. Just when I was about to give up and order an official pair of DJI goggles, XREAL releases an affordable option. The Beam is a small device that acts as a wireless bridge between the AIR glasses and other devices that can cast their screens.

You just cast your screen to the Beam in the same way you might cast to a Chromecast from Android or to your Apple TV from your iPhone. The screen or app is then displayed in the glasses. It has a battery that can power the glasses and the Beam itself for a couple of hours. The Beam device is doing quite a bit of the heavy lifting when it comes to processing the wireless video.

The Xreal Beam is a Wi-Fi screen mirroring companion device for the AIR/2 glasses.

It was all I needed to realize the first-person drone pilot experience. I connected my phone to the drone’s remote as normal. Then, I put on the AIR glasses and connected them to the Beam with their USB-C cable. I opened the DJI 4 Go software and logged in to the drone from my phone after I mounted it in the remote’s clamp, then used Smart View on my Samsung phone to cast its screen to the Beam.

The resulting experience was fantastic. The DJI app is rendered in near life-size on the AIR’s OLED display. The screen inside the glasses looks like a giant monitor because of the proximity to your eyeballs. The app shows the drone’s first-person view that is overlaid with pilot info. The heading, speed, altitude, GPS location, and object detection are all visible and easy to read because they are huge.

Casting the app to the Beam is almost perfect.

Flying in FPS is so much easier for my video game trained brain than ground piloting is. The thing is, though, when I remove the AIR’s sunshields, they become transparent. This allows me to see both the FPS view and the drone in reality simultaneously. As far as I know, this feature is unique to a setup like mine.

I was at a farm when I tested using the AIR and Beam in combination with my drone and phone. The signals involved are the 2.4 and 5 Ghz Wi-Fi bands for the most part. I was able to pilot the drone about one hundred meters away before the video signal dropped.

The video in the glasses was fast, clear, and smooth enough that I felt comfortable going into Sport mode and pushing the little tone to its max speed (40/64). I don’t think any DRL pilots are going to be ditching their goggle setups for this one anytime soon, but these things are awesome for an amature. Especially if you already have most of the equipment on hand.

I began my journey with quadcopters several years ago. I started out with in-expensive micro drones and gradually progressed up to a DJI Mavic Air. I’m an accomplished pilot now and have captured thousands of pictures and countless hours of video. You can read about my experience in a previous post here.

I’ve had the Mavic Air for a year and I’m more impressed with it now, than I was the day I bought it. One of the most surprising aspects of the powerful little flyer is how durable it is. Even after a year of being hauled around in backpacks, laptop bags, car trunks and plane luggage, there isn’t a mark on it. I’m still using the original props! I can ‘t think of any other flying vehicle that I’ve owned that didn’t need at least, new props a few weeks or months in.

There have been several major software updates for the Mavic Air since I unboxed it. The updates can catch you off guard; you’ll boot up to catch some video of your dog only to be hit with the firmware required message. Thankfully they’ve added a feature to update later. The phone app can hang on the unzipping of files during big updates, but you just need to close and restart it. The software has been noticeably improved. The user interface has remained largely the same but multiple bugs have been corrected. I can’t remember the last time the app froze or crashed during flight, which was a frequent occurrence at the start.

The AI has been in school for the last few months, it now flies the drone better than I do. Object avoidance, pre-programmed dramatic shots, follow me, return to home, and TapFly are all improved. My use of the quadcopter has evolved from that of a flying toy to a camera platform, so I find myself using these automated functions much more frequently.

You might be wondering what a drone could be used for besides taking pictures. They’re surprisingly versatile machines; here are a few of the cases I’ve encountered so far:

Lost pet locator
Sky surveys of friend’s homes and property
Examining roofs for hail damage and lost toys
Chasing off various unwanted creatures: stray dogs & cats, racoons, opossums, bats, it’s a long list
Getting close to dangerous things: Fire, Fireworks, Wildlife, Guns, Bees, Wasps, etc. the FPS view makes you feel like you’re there in the action

While looking back through the photos and videos for this article, I can’t help but smile. I’ve got some fantastic shots that would be impossible to get without the little machine. Quadcopters are not just for aerial pictures and videos. They’re great for anywhere that a human doesn’t easily fit, or places that would be too dangerous to be in, they make great tripods too.

Now that I’ve had a great camera drone for a year, I can’t imagine not having one. Especially a compact unit like the Mavic Air. I carry it with me almost everywhere since it folds up and fits in my laptop bag. I was a little skeptical about how much I would use it when I first purchased it and was concerned that it would be a waste of a considerable amount of money. Luckily, it turns out that my instinct to get one was justified. I consider it to be one of my favorite gadgets and look forward to all the things I’ll be doing with it in the future.
