Picture of DIY Hovercraft

When you are a child, do remote control cars in the shop attract you? Do you feel sad when you can’t own a car and play with it? If the answer is “yes”, why not build your own remote control vehicle—a hovercraft now? You can make a hovercraft as long as you follow our manual. This task was initiated from course Vg101: introduction of Engineering at UM-SJTU Joint Institute. 5 freshmen students formed a team called "Angelnearing" to build a wireless control hovercraft. It will take two people 4 hours to finish the hovercraft.

Materials: Tools:

· Blower Knife

· Ducted fan Scotch tape

· Servo Pencil

· Electronic speed controller Compass

· Conversion interface Double-sided foam tape

· Arduino Uno singlechip PC

· Arduino and breadboard shield Screwdriver

· Bluetooth module

· Battery(1500mAh)

· Baseboards

· Dupont Line

· Plastic bag

· Insulation foam

· Rigid foam

· Cellphone with Bluetooth

· M3 screws and nuts

Step 2: Programming

Download the controlling program to your Arduino

  • Download Arduino software into your PC; the website address is http://arduino.cc/en/Main/Software#toc1
  • Connect your Arduino Uno singlechip with your computer. If the LED light on the singlechip isn’t lit, reconnect the singlechip.
  • Warning:If your PC has never connected with a Aruduino before, install a plug-in.
  • Paste the code into your arduino software. Click upload bottom on the interface. The code is in the appendix.

Step 3: Cutting boards to build main structure

Cut two 25cm*30cm baseboards.

Baseboard 1:·

  • Draw a 5.8cm*3.3cm rectangle 3cm away from one of the shorter sides of the baseboard.
  • Draw another 4.3cm*2.0cm rectangle 2.5cm away from the other shorter side of the same baseboard.
  • Cut along the edge of these two rectangles by a knife and remove them.
  • Dig four holes around the 4.3cm*2.0cm rectangle (two holes on each side).
  • Waring: The size of the holes should be smaller than the size of the nuts.

The figure 2 is the size of each part on Baseboard 1.

Baseboard 2:

  • Cut two 18cm*3cm bars from the other baseboard. Cut the corners of the board as 4 4cm*4cm triangles

The figure 4 is the size of each part on Baseboard 2.
