Control a Quadcopter over Websockets

Everyone’s favourite IOT module, the ESP8266, is often the go-to choice for any project that needs quick and cheap control over the web. [Andi23456] wanted to control his quadcopter using the luxury of his mobile phone and thought permanently tethering an ESP12-E module to the quadcopter was exactly what he required.

The ESP8266, really showcasing its all-round prowess, hosts both a web server for a HTML5 based joystick and a Websockets server so that a client, such as a phone, could interact with it over a fast, low latency connection. Once the ESP8266 receives the input, it uses interrupts to …read more

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

Can Commodity RC Controllers Stay Relevant?

Visualize some radio controlled airplane fanatic of yesteryear, with the requisite giant controller hanging from a strap, neck craned to see the buzzing dot silhouetted against the sky. It’s kind of a stereotype, isn’t it? Those big transmitters were heavy, expensive, and hard to modify, but that was just part of the challenge. Additionally, the form factor has to a degree remained rigid: the box with gimbals — or for the 3-channel controller, the pistol-grip with the big pot that looks like a cheesy race car wheel.

With so much changing in RC capabilities, and the rise of custom electronics …read more

Rewire Your Own Brushless Motors

Hackaday likes the idea of fine-tuning existing hardware rather than buying new stuff. [fishpepper] wrote up a tutorial on rewinding brushless motors, using the Racerstar BR1103B as the example. The BR1103B comes in 8000 Kv and 10000 Kv sizes,  but [fishpepper] wanted to rewind the stock motor and make 6500 Kv and 4500 Kv varieties — or as close to it as he could get.

Kv is the ratio of the motor’s RPM to the voltage that’s required to get it there. This naturally depends on the magnet coils that it uses. The tutorial goes into theory with the difference …read more

Drone License Plates: An Idea That Won’t Stave Off the Inevitable

As more and more drones hit the skies, we are beginning to encounter a modest number of problems that promise to balloon if ignored. 825,000 drones above a quarter-kilo in weight were sold in the U.S. in 2016. The question has become, how do we control all these drones?

Right now security and municipal officials are struggling with the question: what to do if there’s a drone in the sky that’s not supposed to be there? This is not just hypothetical. For instance, in the west, firefighting planes have turned away from a forest fire because some idiot with a …read more

This Drone Can Fly, Swim, and Explode….. Wait, What?

You’ve probably heard of micro-drones, perhaps even nano-drones, but there research institutions that shrink these machines down to the size of insects. Leading from the [Wiss Institute For Biologically Inspired Engineering] at Harvard University, a team of researchers have developed a miniscule robot that — after a quick dip — literally explodes out of the water.

To assist with the take off, RoboBee has four buoyant outriggers to keep it near the water’s surface as it uses electrolysis to brew oxyhydrogen in its gas chamber. Once enough of the combustible gas has accumulated — pushing the robot’s wings out of …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
