Drones have revolutionized the world of videography in perhaps the biggest way since the advent of digital hardware. They’re used to get shots that are impractical or entirely impossible to get by any other means. The [Dutch Drone Gods] specialize in such work. When it came to filming an urban mountain bike race in a dense Chilean city, they had to bust out some serious tricks.
Typically, running a drone chase cam behind a biker would require some good first-person flying skills and a quick drone. However, for the Red Bull Valparaiso Cerro Abajo urban downhill event, this alone would not be enough. The tight course winds down staircases between thick concrete walls and even through houses, presenting huge challenges to maintaining signal integrity. Without a clear video signal, the pilot can’t fly the drone without crashing.
To make this all possible, the team used a variety of techniques to help combat the uncooperative radio environment. Directional antennas were used to target different sections of the course. Additionally, a second drone was flown high above the course carrying a radio repeater, helping provide a better line-of-sight contact to the camera drone following the riders when the buildings would otherwise block the signal to the pilot.
Even with all this work, the signal was still scratchy and would cut out at some points. However, with a bit of blind faith when cutting through the worst areas, the [Dutch Drone Gods] and the [Red Bull] team were able to put together an amazing FPV drone shot shadowing [Tomas Slavik] on his run down the extremely difficult urban course.
Details on the precise hardware are scarce. However, it’s something that any experienced drone builder could probably whip up without too much trouble. The idea of using a drone-based repeater is particularly exciting, and something we’re sure could help out many pilots who find themselves operating in difficult urban environments.
No one noticed the two men in the alley as the darkness of midnight approached – their long, black trench coats acting like a soldier’s camouflage.
“You got the goods?”
“Yeah, these are hot man…super fast..check this…”
The bark of a police siren broke their whispered conversation like a shattering glass, causing the two men to briefly freeze in their steps.
“Johnny B. got busted last week…did you hear?”
“No way man! What he get busted for?”
“Drone racing man…drone racing.”
Deep within the shadows of abandoned warehouses and dilapidated factories on the outskirts of Australian suburbia, the telltale buzz of numerous drones can be heard. Zipping to and fro at speeds upwards of 60km/h, these drones are not just flying. They’re racing each other. The operators use specialized FPV goggles that allow them to see the raceway in real time. This method, unfortunately, puts them on the wrong side of the law.
The dated laws governing drones in Australia are similar to those in the US, which were written for the radio controlled plane industry. While they technically forbid any flying outside of line-of-site, the Australian Civil Aviation Authority seems to be OK with the drone racing so long as it’s done indoors and poses no risk to people or property.
Know of any drone racing in your country? Is it legal? Do people do it anyway? Let us know in the comments.
Every once in a while, the Hackaday Overlords have a Hardware Developers Didactic Galactic in San Francisco. Last week was #06 featuring [Mike Estee] from Othermill and Hackaday writer [Joshua Vasquez] talking about synthesizing an SPI slave in an FPGA. Video here.
It’s no secret that [Fran] is building a DSKY – the part of the Apollo guidance computer that was on-screen in Apollo 13. It’s time for a project update, and here’s where she stands: if anyone has a source of JAN-spec Teledyne 420 or 422-series magnetic latching relays (they’re in a TO-5 package), contact [Fran]. The backplane connector has been identified; it’s a Teradyne I/O 100 series connector with a 120mil spacing. Contact [Fran] if you know where to get them.
Let’s say you want a carbon fiber quadcopter frame. What’s the most reasonable thing you can do? 3D print a CNC machine, obviously. That’s a 200mm FPV racer cut from 1mm and 3mm carbon fiber sheets, but the real story here is the CNC machine. It’s a PortalCyclone, and even the cable chains are 3D printed.
