This is a remote control hovercraft. You can drive it in any patterns with the PS2 controller.

A lifting fan is on the bottom. Two propellers are on the rear. We used foamed plastic baseboard to keep it light.

This manual will help you build your own hovercraft. It costs about 800RMB.

Difficulty level and time required

You need Arduino programming skills. If you are not familiar with this, see the website: http://www.arduino.cc/ .

The mechanical structure is simple. You just need to follow our steps.

All the assembling works could be done within 1 day.

Step 1: Prepare Materials

You can get all of these materials from www.taobao.com. Here is a list of the materials and tools (corresponding to the pictures):

  1. Two brush motors (180 motor) and fans.
  2. An electronic speed controller (40A)
  3. Adhesive tapes
  4. A PS2 remote controller
  5. DuPont wires
  6. A Brushless motor
  7. A motor driver (L298N)
  8. A battery(11.1V 2200mAh)
  9. Pliers
  10. Screwdrivers
  11. A cutter knife
  12. T-plug wires

Besides, we need some plastic film and foamed plastic, which we can get from our daily lives.

Step 2: Make Your Baseborad

The initial foam board is 20cm*30cm.

Cut 6cm from its edge and get a 20cm*24cm base. At the midpoint, dig a circle with a radius of 3 cm.

The lines on the picture show the arrangement of following items:

  1. Battery
  2. Arduino mega board
  3. Motor driver
  4. Lifting fan
  5. Propeller
  6. Skirt

Step 3: Prepare Some Fixed Blocks

We need several foam blocks to fasten the fans and support the structure.

As shown in the picture, we need blocks in the following sizes:

  1. Two 5cm*5cm*2cm blocks(fix two brush motors on them)
  2. A 10cm*10cm*7cm block (dig a hole in the shape of the brushless motor)
  3. Four 3cm*2cm*1cm blocks

Step 4: Make the Skirt

  1. Prepare a plastic film larger than the baseboard. Leave 5 cm out of each side. You can mark the lines before cutting.
  2. Stick four 3cm*2cm*1cm foam blocks to the four corners to support the hovercraft.
  3. Fold 2cm plastics film in each side and glue them on the base board. Then seal the corners.
  4. Slice two outlets on the bottom 2 cm from the central round hole. The length of the outlets is 7 cm. Then seal the inner sides of both outlets to ventilate.

Step 5: Fasten the Lifting Fan

The lifting fan is the core of the hovercraft. The fan will provide a strong force to lift the hovercraft.

We recommend you to use hot melt glue to fasten this structure. You need to stick the brushless motor to the foam block and then stick the block to the baseboard.

Step 6: Connect the PS2 Receiver

Connect the PS2 receiver to the Arduino board with the DuPont wires. The ports on the Arduino board depend on your program. You can find details about using the PS2 controller at http://www.billporter.info/2010/06/05/playstation-2-controller-arduino-library-v1-0/.

We recommend you to wrap the pins with adhesive tape.

Step 7: Connect the Motor Driver

  1. Connect the motors to the motor driver with DuPont wires. (OUT1~OUT4)
  2. Connect the power ports to battery. We use the 12V port.
  3. Connect the motor driver to the Arduino board with the six DuPont wires:
    • Attach ENA and ENB to the PWM ports (pin 2-13 on the Arduino board).
    • Attach IN1~IN4 to the Digital ports.

Step 8: Connect the ESC (electronic Speed Control) and the Brushless Motor

  1. Connect the ducted motor to the ESC with three wires. (Once you find the direction of spinning is reverse, exchange any two of these three wires.)
  2. Connect the three DuPont wires to the Arduino board and the ESC:
    • Attach the red one to the 5V port.
    • Attach the black one to the GND port.
    • Attach the white one to the digital port.

Step 9: Assemble & Test

  1. Glue the propelling motors with blocks to the baseboard.
  2. Place the electronic boards on the baseboard as shown above. (See step 1 if you are confused.)

Now it is almost finished. Upload your program and have fun!

You might need to test the program, circuits or mechanical structures. Pay attention to driving it on the open land!

    Nice! I'm going to attempt to make a 3D printed model of this soon. I'll post pictures when I'm done.
