How To Make Mini Drone (Simple and Cheap)

Hi Friends,

In this instructable, I am gonna share you the story how I managed to a simple and cheap mini- my own. Everything started when I decided to shop a mini RC drone and one of my friends told me to build one instead of buying one.

I can explain you the entire build process in fewer steps. If you like my instructable, please do vote for me in the Make it Fly contest.

Step 1: We Need a Frame

An important mechanical part of any drone is its frame. Everything including motors, battery, and circuitry are mounted on the frame.

I have tried a number of frames as you can see in the pictures, but no one worked well.

I mounted the motors, connected the propellers and connected the battery to the motors but none of the frames were stable.

Step 2: Make a Good Frame.

I referred many websites regarding the parts of a drone and the importance of every part

Studied more about the frame and the physics of a good frame. Studied about three rotor drones, four-rotor drones, and other multi-rotor drones. Finally decided to make a four-rotor drone.

A well designed and balanced frame should be symmetric about its center of gravity and its center of gravity(CG), the center of mass (CM) and the center of symmetry should coincide.

The weight of the frame should be as low as possible.

To make a frame, I collected many plastic pieces from trash and selected the one with the lowest weight.

.Cut the piece of plastic without breaking.

.Draw the shape of the frame as per dimension.

.Make four holes for the motors as per the dimension of the motors.

.Cut and remove the unwanted parts.

.File the frame to perfection.

.Do some final finishing works like sanding and filing the edges.

Step 3: Get Some Motors and Propellers.

Now we need four motors and four propellers.I shopped them online from eBay.in. You can buy this type of tiny motors for mini-drone from a local shop or from online platforms. And the propellers also.

The motor is rated at 3.7 V and it has high rpm.The red or white wire is the positive one and the black one is negative.

Step 4: Put Everything Together.

Now we have the frame, motors, and the propellers. And we have to put everything together.

.Connect the motors to the frame.

.Stick the motor wires on the frame using small pieces of insulating tape as shown in the pictures.

.Then stick a double-sided sticker to the middle of the frame to place the battery and the circuitry.

Step 5: First Test Flight.

Now the motors and the propellers are ready.For the first flight, we need a 3.7 V 150 mAh battery also.

Then

.Connect the positive wires of all the four motors together.

.Then connect the negative pin of the battery to the negative terminals of the motors.

Step 6: How to Communicate?

.Now the flight system is ready.Now how to communicate with the drone wirelessly?Some of my options are

.IR communication using IR remote and phototransistor receiver.

.Bluetooth module.

.433 MHz RF module.

Step 7: Get Some Old Stuff.

I got an old flying toy and took out its circuitry and battery out.This is an IR based system with IR remote control.

.Open the helicopter body.

.Remove the wires and take out the board and battery

Step 8: Connect the Board to the Drone Frame.

We have the frame with motors and the board for control.Now

.Stick the board to the frame using double sided sticker tape.(place it in the exact center of the frame for a balanced flight).

.Connect the motor wires to the motor connection of the board.

Step 9: We Done…!

We are done.Now we can control its flight using the IR remote controller.
