Drone Technology
What is a drone and how do drones work is answered here in this easy to understand article. Drone technology is constantly evolving as new innovation and big investment are bringing more advanced drones to the market every few months.
Below, we discuss UAV technology on the most popular drones on the market which have all the latest drone technology. Most drones will have very similar systems incorporated.
Unmanned aerial vehicle technology covers everything from the aerodynamics of the drone, materials in the manufacture of the physical UAV, to the circuit boards, chipset and software which are the brains of the drone.
One of the most popular drones on the market is the DJI Phantom 3. This drone was very popular with professional aerial cinematographers. While slightly old now, it uses plenty of advanced technology which is present in the very latest drones.
This UAV is ideal to explain drone technology because it has everything in one package. It includes the UAV, gimbal and camera and uses some of the top drone technology on the market today.
In only a few months since writing this article, some new and highly advanced drones such as the DJI Mavic Air, Phantom 4 Pro, Inspire 2 and Walkera Voyager 5 have come to the market.
The fast pace of drone technological innovation is tremendous. I’ve included these latest drone technology advancements in the below article. So this article is right up to date including all links.
How Drones Work
A typical unmanned aircraft is made of light composite materials to reduce weight and increase maneuverability. This composite material strength allows military drones to cruise at extremely high altitudes.
Drones are equipped with different state of the art technology such as infra-red cameras (military UAV), GPS and laser (military UAV). Drones are controlled by remote control system also sometimes referred to as a ground cockpit.
An unmanned aerial vehicle system has two parts, the drone itself and the control system.
The nose of the unmanned aerial vehicle is where all the sensors and navigational systems are present. The rest of the body is full of drone technology systems since there is no need for space to accommodate humans. The engineering materials used to build the drone are highly complex composites which can absorb vibration which decreases the noise produced and also light weight.
What Is A Drone – UAV Technology
Below we examine the science and drone technology behind the DJI Phantom 3 UAV. However, we also have plenty of information on the latest drone technologies from the newest drones on the market. There are plenty of links where you can read deeper into various components of drone technology. For example, here is a terrific drone components overview article. This gives you a breakdown of the individual components seen in most drones.
Drone Types And Sizes
Drones come in a wide variety of sizes, with the largest being mostly used for military purposes such as the Predator drone. The next in size are unmanned aircraft which have fixed wings and require short runways. These are generally used to cover large areas, working in areas such as geographical surveying or to combat wildlife poaching.
VTOL Drones
Next in size of drones and are what is known as VTOL drones. Many of these are quadcopters but not all. VTOL drones can take off, fly, hover and land vertically. The exact meaning of VTOL is “Vertical Take-Off and Landing”.
Many of the latest small drones such as the DJI Mavic Air and DJI Spark can be launched from the palm of your hand.
Radar Positioning & Return Home
Many of the latest drones have dual Global Navigational Satellite Systems (GNSS) such as GPS and GLONASS. Drones can fly in both GNSS and non satellite modes. For example DJI drones can fly in P-Mode (GPS & GLONASS) or ATTI mode which doesn’t uses satellite navigation.
Highly accurate drone navigation is very important when flying and in drone applications such as to build 3D maps, surving landscape and SAR (Search & Rescue) missions.
When the quadcopter is first switched on, it searches and detects GNSS satellites. High end GNSS systems use Satellite Constellation technology. Basically, a satellite constellation is a group of satellites working together giving coordinated coverage and synchronized so that they overlap well in coverage. Pass or coverage is the period in which a satellite is visible above the local horizon.
The radar technology in the drone will signal the following on the remote controller display;
signal that enough drone GNSS satellites have been detected and the drone is ready to fly
display the current position and location of the drone in relation to the pilot
record the home point for ‘Return To Home’ safety feature
Most of the latest drone have 3 types of Return to Home drone technology as follows;
Pilot initiated return to home by pressing button on Remote Controller or in an app.
Low battery level where the UAV will fly back automatically back to home point.
Loss of transmission between the UAV and Remote Controller with the UAV flying back automatically to its home point.
The latest Mavic Air RTH feature can sense and actively attempts to avoid obstacles during automatic return to home. The Mavic Air RTH obstacle avoidance works as follows if the lighting is sufficient;
The Mavic Air slows down when an obstacle is sensed
It will stop and hover, then fly backward and ascends upwards until no obstacle is sensed.
Next the RTH process resumes and the Mavic Air will return to home point a the new altitude.
Obstacle Detection And Collision Avoidance Technology
Many drones are now equipped with collision avoidance systems. These drone vision systems use obstacle detection sensors to scan the surroundings, while software algorithms and SLAM technology produce the images into 3D maps allowing the flight controller to sense and avoid the object. These systems are fusing one of more of the following sensors to sense and avoid obstacles;
Vision Sensor
Ultrasonic
Infrared
Lidar
Time of Flight (ToF)
Monocular Vision
The latest DJI Mavic 2 Pro and Mavic 2 Zoom have obstacle sensing on all 6 sides. The Mavic 2 uses both Vision and Infrared sensors fused into a vision system known as Omnidirectional Obstacle Sensing.
The DJI Mavic 2 obstacle sensing system goes to the next level where it can actually fly around obstacles in front or when flying backwards. If it is unable to work out a flight path around the object, it will then hover in front of the obstacle. This is known as APAS (Advanced Pilot Assistance System) on the DJI Mavic 2 and Mavic Air drones.
How many would you have answered correctly? Me, probably 2...maybe 3, with a lucky guess on 'lizard'.
AEC's answer to the Bristol Lodekka was its "Bridgemaster". They were not handsomely proportioned vehicles. That squared-off, unfinished-looking front offside wing is the sore thumb of this Park Royal-bodied example seen emerging from the Canon's Marsh coach park, Bristol, on Saturday 30th July 1977. It had been new to City of Oxford Motor Services and subsequently passed to Premier Transport, Cambridge ...whose fleetname is still displayed on the side. Its owner at the time of the photograph is unknown, but non-PSV by the look of it.
The gentrification of this area was already beginning and the former dockside sheds in the background may, at that very moment, have been hosting the Bristol International Wine Festival ...a great fetish of the City Council's dring the 1970s. I can't think whether the "Watershed" arts centre, with associated shops catering to trend-conscious young people, had yet arrived. I haven't been down here since "regeneration" began to take place on a large scale about 20 years ago.
我不想知道你為她做過的事情。

My mom saw me on Flickr the other night and asked me, "Oh. Writing out your thoughts to another photo?". Normally this question wouldn't phase me, but she said it in a kind of mocking tone. And I also know she kind of thinks "photography" is a phase for me. Therefore, my first reaction was to be defensive and responded with something along the lines of, "Having a thoughts about something, like an answer to a question is better than no answer/thoughts at all, no??" Not having any thoughts about things would simply mean you're lost. But having a thought/answer, is a start. Having something to start with, allows for change. Having nothing, you remain in the same place.
Do I know if "Photography" is really just a phase for me? No. But I Do know that I enjoy it! There's no point claiming it's more than just fun and that it intrigues me. For now anyway. =) A lot of the times, we are keen on having definite answers to things. Because with them, we feel more secure, like "all is known". But that's a pretty naive way of thinking because it's not possible. Knowing that we have an Idea, however, and recognizing that all answers are Contextual... and only relevant to the point in time that they are made, allows us to be more flexible to change.
---Man, do I ramble or what? XD
This was taken at Union Station. At one point, this was the platform that my train arrived at in the morning. When I saw the spray painted letters, I knew I had to take this shot because it was already taken in my head.
It was much harder to take than I had thought though! >_< One-handed shots are HARD!! The low lighting and my shaky hands made this a bit blurrier than I'd expected. But I actually like the blur. =) What do you think?

The answer to what is the flower in the "furry flower remains" pic... a Gerbera Daisy!
In this pic, it's in full bloom. It's all downhill from here, but as I've shown (and will show), all its stages are different and interesting. :-)
This flower was such fun to grow... the first time I've ever grown it. I have more pics to post on another day of this interesting flower. Each cycle of its life was so interesting!
Hope you like it. :-)
I've got a lot of questions :/
What am i doing? What am I MEANT to be doing? What's the point? Where am I? Why am I here? Where are YOU, when I need you? Where is everyone going (without me)? Why is everything changing? Why do I have to grow up? Why can't you see that you're as bad as each other? Why can't you GET OVER yourself? Why do I keep complaining about what I have, when I have so much? Why can't you listen to me? Why do I have so many questions? Do you really love me? Why do you keep telling me you love me? Help? Why do I miss you? Why did i write a question mark on my hand that won't come off? Why can't I take a decent photo?
That's the end of my rant. Answers much appreciated. Ta
Oh and I thought it was time for a name change. I got bored =D

So you want to know my number
And you want to know my name
Did I wake you from your slumber
So you could drive me insane
Answer me!
Do you have analogue
Or a digital control?
You don't have a heart
And certainly no soul
Answer me!
I've never heard you laugh
I bet you couldn't even smile
I wasted my money
When your number I did dial
Answer me!
You can't give the answer I desire
That really is a shame
Perhaps I got a crossed wire
Or are you the one to blame?
Answer me!
Phoney words are what you crave
You don't understand what I mean
I'd like to make you misbehave
Call yourself an answering machine!
Answer me you bastard!
Answer me!
I think you're vile
But I know the code to wipe you clean
My finger poised to dial
I'm your worst enemy
I'm a mischievous questioning machine!

In-Vetro, solo show by Koen Vanmechelen at MediaRuimte, Brussels.

"To answer our most fundamental questions, science needs to find a place for the arts and vice versa. Everything is connected to everything else. It is human interpretation and the need to catalogue and separate that divides topics into boxes. The need to know, create, explore and understand provides inspiration to the development of the human spirit.
Science and art share this inspirational foundation, even though through time they've been separated. In his Cosmopolitan Chicken Project Koen Vanmechelen undoes this separation time and again. The work In-Vetro shows the intersection of art and science. The real and the fictitious are joined in a cage that is divided in half. On one side a cockerel, one generation of Vanmechelen's neverending cross-breeding project, cuts the silence by crowing and defending his territory. On the other side the cold truth is lingering in the form of a frozen ark, a container filled with liquid nitrogen that keeps the chicken's DNA intact at a degree of minus 196 degrees. In vitro. The container is full of promise, the embodiment of the future, a genetic back-up for the ignorant cockerel, whispering to it from behind the glass. Life in two of its manifestations, kept in a cage equipped with an alarm. Life can be dangerous and always finds a way.
Behind this scene a laboratory environment throws its shadow over the whole scene. A simple table is bolstering a luring microscope. Every eye can contemplate the dance of the cockerel's sperm on the specimen clamp and see the future. The website and the computer's flatscreen teleport the viewer into the philosophical and multifaceted universe of the Cosmopolitan Chicken Project. On the wall the genealogy of the Cosmopolitan Chicken Project tries to capture the history of the life presented. All the components of this installation can be seen from the street, the view seemingly unobscured by glass (vetro in Italian). For passers-by it is a momentary snapshot, a wonderful Alicean moment through the looking glass. In the basement the Ted-conference video of the artist gives witness of the power creativity and language. Words create worlds".

A large shed on Callaway Road in Franklin County, Virginia. The home is a trailer down the road with the most colorful flower garden. Lots of bright reds, yellows and pinks. A very severe looking older man lives there. Every time I pass the place in the spring and summer, I want to stop and look at the flowers.
So, here are the answers to the contest! There were 37 differences plus two bonus ones, so all answers 37-39 are considered correct.
Ten people sent me their solutions. Nobody had it right, but closest was Jovel, who found 41 differences. Runners-up were Brixe (42) and Martian Cthulhu (30). So Jovel is the winner!
I know it is possible to find even more by counting parts I could not possibly mirror (bicolored hats, goats) or counting one difference as several - but in such cases, the jury is always right, and the jury happens to be me. Sorry!
There is a separate prize for contestants at the Bricking Bavaria fair - they had one extra bonus diference.
So, here's the list, left to right and top to bottom on this mosaic:
1. procession of three/two monks
2. white/red windows
3. different shields
4. black/gray spire
5. printed/blank owl
6. different pillars
7. golden plates/cones in cross
8. different beards
9. round plates/bricks
10. missing king
11. missing goat
12. white/red roof
13. blue/red band
14. windows put in normal/backwards
15. black tile/no tile on rim
16. wheel/no wheel
17. large/small black roof
18. large/small window
19. wall/closed window next to owls
20. round/pointed opening over oils
21. vertical groove/horizontal grooves
22. bottle/cup
23. one/two white bands on turret
24. turret spire in two/three parts
25. square/round brick next to window
26. brick-built/one piece lion
27. knight/robot
28. fairy/witch
29. tan/black window frame
30. white/yellow porch
31. round and square bricks/microfigures in window pane
32. one/two flames
33. straight/diagonal window panes
34. double/single support on fence
35. different torso prints
36. different fence corners
37. different window positions
38. bonus (unwanted difference): missing cheese slope finishing under arch
39. bonus (almost invisible difference): vertical/horizontal grooves behind princess
40. bonus for Bricking Bavaria visitors only: window accidentally put in backwards during the exposition

After replacing those 2 burnt resistors, the loudspeaker drive amplifier seems to work. Here it is connected to the speaker and a test signal (from a test oscillator PCB, not part of the machine), is injected on the pin that would connect to the slider of the volume control. Yes, I got a beep from the speaker.
Ding-dong!
The doorbell was still ringing, and the time by which my parents should've answered the door had passed. I still wasn’t worried, though. They were heavy sleepers.
I got out of bed and clomped down the stairs, loudly clearing my throat. I made as much noise as I possibly could because I wanted my parents to wake up. I wanted them to see me in my pajamas, rudely awakened from a “deep sleep,” just like them.
We would be outraged together, allied in anger against our nocturnal visitor. My curfew-breaking would be forgotten!
I opened the door.
My parents stood on the stoop, giving me the evil eye.
