Introduction: How to Make a Drone
This is a quick and easy guide showing you how to make your very own drone.
Step 1: Gathering Materials
List of things you will need:
1. EUDAX 6 Set Rectangular Mini Electric 1.5-3V 24000RPM DC Motor... These will be the motors that rotate the propellers
2. Breadboard Solderless Prototype PCB Board... You don't need this exact one but this set has enough wires for future uses. These wires will be used to transfer electricity.
3. KEYESTUDIO UNO R3... Or you could get a regular UNO. However, this one is cheaper. This will be the "brain" of the drone
4. Qunqi 2Packs L298N Motor Drive Controller These will act as the middlemen between the Arduino UNO and the motors
6(optional). 3-D printer for the drone body. You could buy one online as long as it's able to house all of these materials.
7. A hot glue gun
8. Electrical tape
Once you have these materials, move on to Step 2.
Step 2: Creating the Body of Your Drone
For this, I used an online 3-D modeling program called TinkerCad. The exact way to make a body like this goes as follows:
Create a main box with these dimensions
*Length: 8 cm
*Width: 6.5 cm
*Height: 0.4 cm
Next, create four legs at 45 degree angles with the corners of the main box. The dimensions for these are
*Length: 10 cm
*Width: 2.5 cm
*Height: 0.4 cm
To create the boxes, apply boxes to the ends of the legs. These should also be at a 45 degree angle and have the following dimensions:
*Length: 2.5 cm
*Width: 2.5 cm
*Height: 3 cm
Finally, you're going to want to create a cavity for the motors to sit in. This can be achieved by situating a smaller box inside of the boxes at the ends of the legs and then clicking the "Hole" option right above the dimensions page. The dimensions for those are as follows:
*Length: 2.3 cm
*Width: 2.2 cm
*Height: 2.5 cm
Once all of this is finished, print it out using a 3-D printer
Step 3: Mounting the Components
To mount the two battery holders, Arduino, and speed controllers I used hot glue. Hot glue is safe to use with these electronics. Note: The batter holders should be mounted to the bottom of the drone frame.
For the motors, I attached the white holders included with the kit that the motors came with. You're going to want to run the wires through the holes in the motor holders and then proceed to glue them down on the edges of the square holes.
Step 4: Wiring
This has to be the most tedious part of the whole project. The wiring is mainly going to take place between the Arduino and the two speed controllers using the wires in the breadboard kit. Explaining every bit of wiring done here would take too long. Here's a link to a guide I followed regarding the speed controllers and how they connect with every other component.
Once you have everything wired correctly, clean it up by using some electrical tape around the wires.
Step 5: Mount the Propellers
Inside of the motor kit you should find some gear mounts. Put these on the metal poles of the motors and press the propellers onto them. If these are not stable on their own, apply some hot glue into the middle-point of where they connect.
Now you have your very own drone. Next steps would be to boot up some Arduino code but that's for a different instructable. Hope you enjoy!
