The Zombie Rises Again: Drone Registration Is Back

It’s a trope of horror movies that demonic foes always return. No sooner has the bad guy been dissolved in a withering hail of holy water in the denoeument of the first movie, than some foolish child in a white dress at the start of the next is queuing up to re-animate it with a careless drop of blood or something. If parents in later installments of popular movie franchises would only keep an eye on their darn kids, it would save everybody a whole lot of time!

The relevant passage can be found in section 1092(d) of the National …read more

The British Drone Law Reaches Parliament

We’ve brought you a variety of stories over the years covering the interface between multirotor fliers and the law, and looked at the credibility gap between some official incident reports and the capabilities of real drones. In the news this week is a proposed new law in front of the British House of Commons that would bring in a licensing scheme for machines weighing over 250 g, as well as new powers to seize drones. We’ve previously told you about the consultation that led up to it, and its original announcement.

As a British voter with some interest in the …read more

Flame Throwing Drone is Actually Useful

A team in Xiangyang, China is using a flame-throwing drone to clear debris from high voltage power lines. These lines are made of metal of course, and are impervious to the high heat of the flames. Any type debris that gets on the lines will be charred to a cinder in just a few seconds. This is all is quite a bit safer than sending a human with some type stick up there near the high voltage lines.

Over the years here at Hackaday, we’ve seen people attach some strange things to drones. We can all recall the drone with …read more

Hyperspectral Imaging – Seeing the Unseeable

They say that a picture is with worth a thousand words. But what is an image exactly? One way ideal would be a perfect reflection of what we see. But our view of the natural world is constrained to a bandwidth of 400 to 700 nanometers within the electromagnetic spectrum, so our cameras produce images within this same bandwidth.

For example, if I take a picture of a yellow flower with my phone, the image will look just about how I saw with my own eyes. But what if we could see the flower from a different part of the …read more

Lithium Ion Versus LiPoly In An Aeronautical Context

When it comes to lithium batteries, you basically have two types. LiPoly batteries usually come in pouches wrapped in heat shrink, whereas lithium ion cells are best represented by the ubiquitous cylindrical 18650 cells. Are there exceptions? Yes. Is that nomenclature technically correct? No, LiPoly cells are technically, ‘lithium ion polymer cells’, but we’ll just ignore the ‘ion’ in that name for now.

Lithium ion cells are found in millions of ground-based modes of transportation, and LiPoly cells are the standard for drones and RC aircraft. [Tom Stanton] wondered why that was, so he decided to test the energy density …read more

Where Can You Fly? Worldwide Drone Laws Mapped

If you are a flier of a multirotor, or drone, you should be painfully aware of the regulations surrounding them wherever you live, as well as the misinformation and sometime bizarre levels of hysteria from uninformed people over their use.

Should you travel with your drone, you will also probably be resigned to being interrogated by airport staff high on The War On Terror security theatre, and you’ll probably not find it surprising that they have little idea of the laws and regulations over which they have pulled you aside. It’s a confusing situation, and it’s one that [Anil Polat] …read more

Delivery Drone Aims To Make Package Handoffs Safer Than Ever

Picture this: you’re at home and you hear a rapping on your door. At last!– your parcel has arrived. You open the door, snatch a drone out of the air, fold it up, remove your package, unfold it and set it down only for it to take off on its merry way. Hand-delivery courier drones might be just over the horizon.

Designed in the [Laboratory of Intelligent Systems] at Switzerland’s École Polytechnique Fédérale de Lausanne and funded by [NCCR Robotics], this delivery drone comes equipped with its own collapsible carbon fibre shield — it fold up small enough to fit …read more

Fidget Spinner Slash Drone is Both

So Hackaday loves fidget spinners and we don’t care who knows it. Apparently so does [Jeremy S Cook], who decided to mash up a spinner and a cheap quadcopter. To what end? Is that even a question? Spinners are the bearing-studded equivalent to the Rubik’s Cube craze of the ’80s and all we can do is embrace it.

[Jeremy] designed a quadcopter shape with a hole in the center matching a VCB 22 mm ceramic bearing he had on hand. He CNCed out the design from a sheet of Lexan resin. Then he detached the electronics amd motors from a …read more

UK To Register Multirotor fliers

The British government has shown a surprisingly light touch towards drone fliers in the face of the strident media demands for them to be banned following a series of reports of near-misses with other aircraft. That is about to change with reports of the announcement of a registration scheme for craft weighing over 250 g (about 9 oz). Details are still a bit sketchy, but it is reported that there will be a written test and an element of geofencing around sensitive locations.

Our friendly professional multirotor flier’s reaction is that the existing laws are clear enough, and that this …read more

DIY Air Cannon Snags Drones from the Sky

Who hasn’t had the experience of a pesky drone buzzing around that family picnic, or hovering over a suburban backyard where bikini-clad daughters are trying to sunbathe in peace? A shotgun used to suffice for such occasions, but with this compressed-air powered drone catcher, there’s no need to worry about illegally discharging a firearm to secure some privacy.

Before the comment line lights up with outrage, the above scenarios are presented entirely in jest. We do not condone the use of force on a drone, nor do we look favorably on those who use drones in a way that even …read more
