Ask Hackaday: How Would You Detect A Marauding Drone?

The last few days have seen drone stories in the news, as London’s Gatwick airport remained closed for a couple of days amid a spate of drone reports. The police remained baffled, arrested a couple who turned out to be blameless, and finally admitted that there was a possibility the drone could not have existed at all. It emerged that a problem with the investigation lay in there being no means to detect a drone beyond the eyesight of people on the ground, and as we have explored in these pages already, eyewitness reports are not always trustworthy.

Radar Can’t

HD Video and Telemetry Link Uses Standard WiFi Hardware

[GlytchTech] decided to implement his own Digital Data Link (DDL) for his drone experiments, and by using a Raspberry Pi Zero and some open-source software, he succeeded in creating a mostly self-contained system that delivers HD video and telemetry using an Android phone as a display.

The link uses standard WiFi hardware in a slightly unusual way to create a digital data link that acts more like an analog system, with a preference for delivering low latency video and a graceful drop-off when signal quality gets poor. A Raspberry Pi Zero, Alfa NEH WiFi card, external antenna, battery, and a …read more

Ooops, Did We Just Close An Airport Over A UFO Sighting?

Picture this: it’s late in the evening on a freezing cold, dark, and windy December night in southern England, and an airport worker at Gatwick — London’s second international airport — sees something fly past in the gloom above the floodlights. The weather and darkness makes it difficult to see what the object was, but the report is phoned in to security. What was it? A flock of birds? A piece of plastic litter caught by the wind and blown through the night? In this case, the call is recorded as a drone. Because the magic D-word has been uttered, …read more

London Gatwick Airport Shuts Its Doors Due To Drone Sighting

If you could pick a news story you would prefer not to be woken with, it’s likely that a major airport being closed due to a drone sighting would be high on the list. But that’s the news this morning: London’s Gatwick airport has spent most of the night and into the morning closed due to repeated sightings. Police are saying that the flights appear to have been deliberate, but not terror-related.

We’ve written on reports of drone near-misses with aircraft here back in 2016, and indeed we’ve even brought news of a previous runway closure at Gatwick. But it …read more

Organic Ornithopter Sensor Drone

Bees. The punchline to the title is bees carrying sensors like little baby bee backpacks. We would run out of fingers counting the robots which emulate naturally evolved creatures, but we believe there is a lot of merit to pirating natural designs, but researchers at the University of Washington cut out the middle-man and put their sensors right on living creatures. They measured how much a bee could lift, approximately 105 milligrams, then built a sensor array lighter than that. Naturally, batteries are holding back the design, and the rechargeable lithium-ion is more than half of the weight.

When you …read more

Tiny Drone Racing Gates Use Up Those Filament Scraps

Drone racing comes in different shapes and sizes, and some multirotor racers can be very small indeed. Racing means having gates to fly though, and here’s a clever DIY design by [Qgel] that uses a small 3D printed part and a segment of printer filament as the components for small-scale drone racing gates.

The base is 3D printed as a single piece and is not fussy about tolerances, meanwhile the gate itself is formed from a segment of printer filament. Size is easily adjusted, they disassemble readily, are cheap to produce, and take up very little space. In short, perfect …read more

An Englishman’s Home Is His (Drone-Defended) Castle

Retiring to the garden for a few reflective puffs on the meerschaum and a quick shufti through the Racing Post, and the peace of the afternoon is shattered by the buzz of a drone in the old airspace,what! What’s a chap to do, let loose with both barrels of the finest birdshot from the trusty twelve-bore? Or build a missile battery cunningly concealed in a dovecote? The latter is what [secretbatcave] did to protect his little slice of England, and while we’re not sure of its efficacy we’re still pretty taken with it. After all, who wouldn’t want a …read more

Parcelcopter Drone Project Delivers In Rough Terrain

It’s a known fact that the last mile is also the longest mile in the parcel delivery service. The further removed from a hub city a delivery location is, the more required stops in between. Every part of the process slows to a glacial pace when the drop-off spot is inaccessible by land or air. Now apply this in the case of a medical emergency, and timing is everything.

Enter the joint project between [DHL and Wingcopter] dubbed Parcelcopter 4.0. The half plane, half helicopter drone design was recently tested over a six month period by making medical supply drops …read more

Drone + Ground Penetrating Radar = Mine Detector?

Most civilized nations ban the use of landmines because they kill indiscriminately, and for years after they are planted. However, they are still used in many places around the world, and people are still left trying to find better ways to find and remove them. This group is looking at an interesting new approach: using ground-penetrating radar from a drone [PDF link]. The idea is that you send out a radio signal, which penetrates into the ground and bounces off any objects in there. By analyzing the reflected signal, so the theory goes, you can see objects underground. Of course, …read more

Keep ‘Em Flying with this Monster DIY Battery

If you’ve spent an afternoon at the sticks of a remote-controlled aircraft, you’re probably well aware of the great limiter for such exploits: battery life. In the days when most RC aircraft were gas powered it was easy to cart along some extra fuel to keep the good times rolling, but now that everything except big scale models are using electric motors, RC pilots are looking for better ways to charge their batteries in the field.

Though it might seem counter-intuitive, [Adam Pyschny] is of the opinion that the best way to keep his quadcopter batteries charged is to simply …read more
