Drone Using Leap Motion

Life In Motion

“Here we make use of the leap motion technology with which we can easily control quadcopter using hand gestures that reduces the burden of using a remote”


Quadcopter is a lightweight flying device that can be used for examining areas that would otherwise be hard to reach for a human. Many quadcopters are equipped with tools such as a GPS and automatically leveling cameras.



Leap Motion, Inc. is an American company that manufactures and markets a computer hardware sensor device that supports hand and finger motions as input, analogous to a mouse, but requires no hand contact or touching.

Picture6The Leap Motion controller is a small USB peripheral device which is designed to be placed on a physical desktop, facing upward. Using two monochromatic IR cameras and three infrared LEDs, the device observes a roughly hemispherical area, to a distance of about 1 meter. The LEDs generate pattern-less IR light[25] and the cameras generate almost 200 frames per second of reflected data.[26] This is then sent through a USB cable to the host computer, where it is analyzed by the Leap Motion software using “complex maths”

  • Java
  • Arduino programming

Other parts you will need:

 1. R10K Resistor
2. 2x R2.5K Resistor
Tools you will need:
1. Soldering iron and some solder
2. Desoldering wick
3. Wires
4. Screwdriver
5. Magnifying glass
6. Dremel

Step 1: Remote Controller:

1. Disassemble the remote control and take off all the plastic parts leaving only the remote’s board with the small LCD still attached. I left the same battery holder box and just extended the wires and cut all the excess plastic with a dremel.
2. With a soldering iron and a solder wick, carefully take out the two potentiometers, you can also desolder and take out the annoying buzzer.

3. Once you take out the left potentiometer there are 2 things you need to do –

First you have to add two 2.5K resistors as shown in the circuit picture.

Next thing you have to do is to short three points as shown in the picture.

4. On the left potentiometer, once you remove it you need to short four points as shown in the picture.

Step 2: Digital to Analog Cards:

1. Connect the VCC output from each of the 3 A/Ds (analog-to-digital converter) together to the arduino’s 3V3 input
2. Connect the SDA output from each of the 3 A/Ds together to the arduino’s analog 4 input
3. Connect the CSL output from each of the 3 A/Ds together to the arduino’s analog 5 input
4. Connect the ANALOG output from each of the 3 A/Ds and choose one for the throttle, one for the roll, and one for
        the pitch.
5. Connect the GND output from each of the 3 A/Ds together to the arduino’s GND input
6. Connect a wire to the lower left pin in each of the main chips in the 3 A/Ds and using a magnifying glass:
        in the throttle A/D connect the wire to the arduino’s digital 8
        in the roll A/D connect the wire to the arduino’s digital 10
        in the pitch A/D connect the wire to the arduino’s digital 12

Step 3: Flip Button:

1. Connect the BS170’s Source pin to the arduino’s GND
2. Connect the BS170’s Drain pin to the push button’s upper left pin
3. Connect the BS170’s Grille pin to the arduino’s DIGITAL 5
4. Connect the 10K resistor to short the GND wire and the grille wire.

Step 4:Code

If you dont  require the code then just run “LeapDino.exe”

Hope you understood 🙂

At Nearly 7 Miles Depth, The Mariana Trench Has Some Of The Scariest, Most Bizarre Creatures..!!!

Located in The Pacific Ocean, the Mariana Trench is the deepest part of any of the oceans in the world. It is 1,580 miles long with a maximum depth of 6.831 miles. Its depth makes it pitch black and the temperatures there are few degrees above freezing.  Strange and different sea creatures live here. According to scientists who’ve explored the trench, creatures living here have learned to live in different kinds of severe conditions. They can protect themselves from cold, light up the dark parts of the ocean and manage to evade even the sea’s scariest predators.

  • 1. The Goblin Shark

This terrifying creature measures between 8 and 13 feet. It was discovered first in 1898. The male’s weight can go up to 463 pounds. Those fangs look scary…

2. Hatchet-fish
The hatchet-fish produces its own light using special organs. They are mostly found at 600 to 4500 feet and this is why they need the protruding sensitive eyes.
3. Footballfish
It’s vaguely shaped like a football and uses a bulbous lure to draw its prey before using its jaws to snatch it up.

4. Frilled Shark

The frilled shark is prehistoric with 300 trident-shaped teeth that are neatly aligned in 25 rows. According to scientist, this beast takes 3 and a half years to give birth. It’s a gestation period record holder!

5. Dumbo Octopus

The Dumbo octopus earns its name from its ear-like fins. It lives at depths of between 10,000 to 11,000 feet. The Dumbo Octopus feeds on worms and other crustaceans found on the sea floor.

These creatures can be termed as the cutest on the Mariana Trench.

6. Fanfin Seadevil

Their males grow to about ½ an inch in length while the female can go up to 8 inches. The right words to describe the male during breeding can only be ‘overly attached’. This is because it fuses itself onto the female and shares the female’s bloodstream just like a parasite. See, very overly attached!

7. Dragon fish
The dragon fish produces its own light. To attract potential mates and prey, the dragon fish uses a flashing barbell that’s attached to its chin. This creature uses its pitch black stomach to hide unlucky prey.

8. Telescope octopus


This octopus has an incredible vision range due to its rotatable eyes that are on top of its long movable stalks. It appears ghost-like due to its transparent body.

9. Barreleye
It’s mostly found at depths of 2000 feet and is most notable for its highly sensitive eyes and transparent head. The barreleye has green lenses found above each of its eyes. These allow it to filter any light that makes it to those depths of the sea and helps it focus on the lights from its prey. Cunning creature!

10. Viper Fish

The viperfish has teeth so long they can’t fit in its own mouth! They instead curve back towards its eyes. It’s found at 5,000 feet and to take out prey, it swims at high speeds and impales the victim using its fangs. They only grow to 12 inches in length but look terrifying.

11. Fangtooth
The fangtooth has the largest teeth known in the ocean. Despite its fearsome weaponry, however, if it veered closer to the surface, it would be food for the tuna since it only grows to six inches in size.

12. Hirondellea Gigas
They live in the deepest parts of the sea. Swarms of up to two inches long are found at 30,000 feet where food can rarely be found. They feed on plant and tree debris that make it to the sea bottom. They also digest what other fish consider trash using special enzymes produced in their guts.

13. Ping-Pong Tree Sponge
They can be found at 9,000 feet and are carnivorous. The ping-pong tree can grow to a height of 20 inches.  They may not look dangerous on sight but they have tiny hair hooks that they use to catch small creatures passing by. Cells in the sponge, then slowly move towards the prey and digest it.

14. Enypniastes

The enypniastes is a sea cucumber that lives at 16,400 feet. The mouth is the red area and around it are tentacles that scoop up from the sea floor, edible mud. It leaves nothing to the imagination as you can see.

As an environmentally concerned person I tend to read news about plastic bags. One of the most common things I encounter are people who agree that plastic bags are bad, but lament the fact that it is difficult to remember to carry your reusable bag. Well, here’s a simple solution. Just tuck a couple of these into your pocket or purse, put a few into your car’s glove compartment and you’re always equipped to shop and not use any plastic bags.

Friends Forever!

“A true friend is someone who is there for you when he’d rather be anywhere else‘ and ‘In the end, we will remember not the words of our enemies, but the silence of our friends’. 
What is life without friends? The wise say that 1000 relatives = 1 friend.
We are sure all of you have had special friends in different phases of your life. Some may be still in touch and some may have lost touch. Let us recollect all the good times and remember those wonderful moments spent with our friends”



“Every memory remains

as the days pass quickly by
as i look upon the past
my heart just wants to cry


we were always together
through the good times and the bad
i try to keep a smile
but i cant fight the feeling sad
your laugh was addicting
and so was your smile
now everything’s changing
and I’m stuck in denial
the person that has changed
at first i thought was you
but i realize now its me
but its not i changed, but grew
everyone will change
and everyone will grow
but i will always forever love you
and that i hope you know
guys got in the middle
and other factors too
i guess one thing thats changing
is that I’m now jealous of you


i miss so many things
about the way it used to be
we both have made mistakes
not “just” you or not “just” me
i miss all of the good times
like when we’d talk all night long
or when we’d belt out the lyrics
to an old barney song
when we’d fall over laughing
and we wouldn’t know why
all the hugs you gave me
when all I’d do is cry
i miss your blond moments
and the things we would say
acting like stoners
day after day
i miss when we’d talk
for hours on end
but i think most of all
i just miss you”
