Long Range DJI Drones

Drone technology has grown by leaps and bounds and consumer drones have greater range than ever before. This range doesn’t come without its limitations.

Range of DJI Drones

Drones like the DJI Phantom along with the DJI Mavic have ranges of around 2 to 3 miles, with the Mavic 2 pro going up to 18 km! These drones can maintain a radio link to a video connection and the pilot.

Drone cameras are great for capturing landscapes and things from afar, but they are not very good at imaging close up objects in detail.

For example, a quadcopter could take video or a superb overhead photograph of a building, but their faces would not even be recognizable when there was someone on a balcony said building.

So far as aerial photography programs are concerned, the DJI Mavic and DJI Phantom will be the leaders with great range and superb radio technologies that maintain a connection and also has a Return to Home failsafe where the copter would safely fly back to you in case of an interruption or disconnection from the radio link.

Range of racing quads

The range of most frequent racing quads, while the potential to be rather far with today’s technology, is limited by FPV range and battery lifetime.

You can maintain a radio link over very large distances — the TBS Crossfire radio platform advertises their scope to be up to 40km. Most miniquad radios however operate by default to the 2.4gHz range, where it is possible to expect a good radio link up to 1 km or maybe a bit more, depending on your receiver.

So while long range flights are actually possible with the TBS Crossfire, they’re slightly risky as one wrong move could lose you a quadcopter.

Battery life

Racing have miniature batteries which push four propellers to spin fast and are extremely tiny machines quadcopters, or miniquads. The flight period you’d get out of a miniquad will be 3-5 minutes with propellers and the current motors. You hope to come back and can’t go too much in that much time. Sure, if you are pushing the quad in the 100 km/h, which is totally possible, you can cover a distance fast, but you also need to fly back!

Because they utilize slower motors and propellers larger quadcopters have better battery life, but even then they may be restricted by FPV range.

FPV range

Whenever you’re flying FPV, then range becomes even dicier, especially in areas with a great deal of obstacles.

Most FPV techniques operate on the 5.8 gHz spectrum, which has even less range than 2.4 gHz commonly used in radios. With the right antennas along with transmitter/receiver combo, you couldpush 5.8 gHz movie to 1 mile or so away, but that’s if there’s nothing between you and the quadcopter — if you’re in an open field and fly straight out, or if you fly high and straight out so that there is a direct line between you and the quadcopter that doesn’t undergo any obstacles in between.

They are suited to planes more, although there are long range FPV systems that work on lower frequencies which can give array of 10-20 kilometers.

STIK Clique Inspiration with Designer Christina Fagan

Christina Fagan is the creator and leader knitting officer of Sh*t I Knit (STIK). STIK began as a silly site in faculty but turned into something actual in February 2015 when her unwanted business become a full-fledged small business. Are you currently a part of this STIK Clique yet?

What does it mean for you to be a manufacturer?

I enjoy making things with my hands, and having the ability to sit down with a few arbitrary stuff and finish with a final product is really cool. Being a “manufacturer” is this a cool thing nowadays using the DIY motion, but I am so happy that it is something I have always enjoyed performing. I can not sit still, so I am thankful I have discovered something productive to do with my hands once I have to.

My mother taught me how to knit once I was ten, and it has always been a passion of mine. In addition, I have something of a watch about what people need, therefore I have always concentrated on creating bits that are on trend. I believe that mix has propelled me to the knitwear area.

I actually like to create things I wish to wear. You could say I’m pretty preppy, also that I enjoy classic lines and chunky knits. In addition, I enjoy watching how other knitwear designers are taking risks, which compels me to try new items: larger pom-poms, brighter colours, new lines, etc.. In the conclusion of the afternoon, I truly prefer to design things I wish to use, but I believe my preference changes all the time. Visit us here to learn more about knitting ideas and benefits.

How can you keep up a creative life?

It is not always simple! In the last year, an individual may feel that I have been swimming in imaginative bliss, even when in fact running your own business means coping with a great deal of daily sh*t which isn’t too creative in any way. In addition, I prefer to change it up–I have a ceramics course where I could toss bowls for hours and only let my mind wander.

How have you ever made a public character from a craft?

During Instagram, I have been able to produce a voice to your brand that reaches tens of thousands of followers. I have been in a position to invent an authentic narrative around the craft of knitting, which has been demonstrated to be interesting enough for people to follow along within the previous year. I do a good deal of public relations outreach, and that I associate with a lot of bloggers to discover new audiences.

What do you really desire the STIK Clique along with other crafters to get out of your job?

2 things: I need people to smile when they hear our new, and that I need them to appreciate the products which we make. I hear a good deal of comments from our clients that they get stopped on the road whenever they are wearing one of our hats.

3D Pens, should you use PLA or ABS?

What are 3D Pens

3D Pens are currently one of the hottest topics in the ever-changing tech industry. Should you not have heard about this remarkable new device that allows you to paint in the air, creating solid, permanent structures from thermoplastics such as PLA or ABS, then you should read on to find out more.

Let’s first take a look at some images, which you can create with a 3D pen, to paint the picture so to speak.

3d printed bag

Here we have a bag created by a 3D artist called Kseniia Snikhovska; you can visit her website by clicking the link to her website.

Yep, this is exactly why is this technology captivating the tech market. It adds another dimension to art.
The adage, technology is merely a vehicle for art, (read more about this in The Guardian’s post) holds true here.

So with the possibilities of creating new, practical and even functional art pieces being endless, what kinds of plastics are required to combine with the magic of the 3D pen in creating 3D art.

Well, two plastics are currently dominant in the 3D printing industry.


Yes, just like 3D printing applications love these plastics for creating large-scale 3D prints, so 3D pens love these plastics due to their ease of use, practicality, durability and longevity.


PLA is far more suitable for beginners or kids, since its completely non-toxic and melts at a lower temperature.
It has the downside of being bio-degradable, a pro for the environment but not for the longevity of your 3d prints or paints.

If you leave PLA in the sun or outside it will eventually start to degrade, and the layers will separate.

The colour palette for PLA is possibly the biggest of all thermoplastics.

Let’s list the advantages of PLA:

  • PLA plastic is easy to use and child-friendly.
  • It is tacky and sticky, enabling you to print and print on surfaces like ceramics and glass.
  • Biggest colour palette
  • Increased fluidity with excellent cohesion between layers, making it very durable


ABS is possibly the most popular 3D printing material, and it can be used for any 3D print. ABS is strong, shatter-resistant, non-biodegradable and available in a variety of colours.

ABS is can also dissolve in acetone which can give it a very smooth finish.

Let’s take a look at the advantages and disadvantages of PLA vs ABS.

  • It’s the most popular 3D printing material
  • It is Hard and Shock resistant
  • ABS plastic often has a glossy surface via acetone finish
  • ABS is not biodegradable but can be recycled.


At the end there is truly no winner, each of the two plastics has unique benefits and properties. PLA vs ABS, the choice is determined by what you need to print, and your experience with 3D printing.

Should you be interested in learning more about the advantages and disadvantages of PLA and ABS, as well as the properties and an in-depth printing guide, be sure to check out Pen and Plastic’s PLA vs ABS comparison.

As always, feel free to leave us a comment in the section below, we love to hear what you think about these two types of plastic filaments.

Microsoft Photosynth – An Unknown Yet Majestic Tool

Two years ago, Microsoft wowed audiences with technology to explore the world through digital photos.

The company demonstrated Photosynth, software that arranges photo sets in their real-world, 3D context and allows people to navigate smoothly around the canals of Venice, for example, or zoom in to read the serial numbers on the space shuttle’s heat shields.

Now anyone can make a “synth,” documenting anything from a favorite sculpture to a real-estate listing to a city skyline in a new way. Microsoft released the free online service Wednesday night.

“We talk about the Internet bringing things to you, but the current Internet is so limited,” said David Gedye, Photosynth group manager. “It’s so slow, it’s so click-based. It’s a tiny little keyhole that you’re looking at the world through, and this is like a picture window.”

Since Microsoft’s small Live Labs team began showing off Photosynth in 2006, the top request has been for a version that individuals could use.

It starts at Photosynth.com, where people can open an account (with a Windows Live ID) and begin creating “synths,” which require only an off-the-shelf digital camera and an 8-megabyte software download.

There are also already dozens of “synths” to view on the site, including several from National Geographic, which assigned photographers to document wonders of the world such as Stonehenge using Photosynth.

“If we’re successful with this, we’ve actually invented a new media type that’s halfway between photos, computer games and video,” Gedye said, citing Photosynth’s rich detail, user-controlled navigation and a cinematic qualities.

Rob Covey, who heads content development and design at National Geographic Digital Media, agrees that Photosynth has the potential to become a new medium.

“We’re just at the beginning of how to use this,” he said.

Microsoft suggests people create synths with 10 to 300 photos shot specifically for this purpose. They should blanket a subject from all sides and variety of perspectives, from panoramas to tight details.

It takes a moderately powerful computer about five minutes to calculate a synth of about a dozen photographs, matching elements they have in common to reconstruct the subject. The processing is done on the machine the synth creator uses, and the completed synth is stored on Microsoft servers.

For now, there is no option to create private synths; they’re all publicly available through the service. Each free account gets up to 20 gigabytes of storage — enough for 20,000, 1-megabyte digital photos.
Larger synths can take several hours to process, depending on the size of the photos and the power of the machine. But that’s still a dramatic improvement.

When Photosynth was demonstrated two years ago, “it took a day and a half on a big cluster of computers to calculate those synths,” said Alex Daley, Live Labs group product manager. The team had to significantly reduce the processing time to make the service usable by a wider audience.

In addition to documentary and travel photography, Photosynth is finding promising commercial applications.

High-end New York real-estate brokerage Brown Harris Stevens Select is using it to show off properties to clients unable to see them in person.

Photosynth offers a much more sophisticated way of communicating a space than even high-end virtual tools, said Shlomi Reuveni, the firm’s executive vice president.

“[It’s] very much like walking through the front door of a home for the first time and fully experiencing every element of design and architecture,” he said.

Artists and galleries are using Photosynth to expose their work in new ways. Scientists are documenting species collections for the “Encyclopedia of Life.” Restaurants are finding a new way to show off the dessert tray.

Photosynth is a distinctly Seattle innovation. It makes use of technology for smoothly streaming large digital images, developed by Seadragon Software, a Ballard startup Microsoft acquired. The system for arranging photo collections in their three-dimensional context was developed by University of Washington computer scientists.

The technologies were united and polished by a core group of about a dozen people in Microsoft’s Live Labs, who are based in Smith Tower and charged with quickly moving promising research into new Internet services.

Photosynth users can assign various rights to their photos in their synths through a Creative Commons license. A user can take down his or her synths at any time, but Microsoft keeps the calculations and analyses it performs to create the three-dimensional framework of the real world that underpins Photosynth.

7 New Technology Gadgets You Must Have!

A gadget is a small technological object (such as a device or an appliance) that has a particular function.
