Simple Electric Propeller Car simple electric propeller car

In this post, you will learn how to make a simple electric propeller car using basic parts and some creativity. This project is great for a makerspace or mechanical engineering challenge at school, library or home. Once you learn the basics, you can experiment with different body styles and designs to make your car go faster. You can also set up a competition between friends to see who can build the fastest propeller car. Make STEAM education fun ! Materials Needed

The good thing about this project is that you can get most of your “car” parts from the trash. You can use cardboard, bottles, boxes and most containers to create the body of your propeller car. Get creative! simple electric propeller car For this tutorial, we are going to show you how to build the car body using cardboard.

propeller car materials Tools Needed You will need some basic tools in order to cut the wire, cardboard and dowel rod. Scissors Wire Snips X-Acto or Razor Tin Snips or similar

simple electric propeller car tools In this tutorial we chose to connect the parts using a hot glue gun. You could also use super glue or another type of quick-drying adhesive.

The first thing you need to do is cut one piece of cardboard to approximately 3″ wide x 8″ long. This section will be the base of the propeller car. Next, cut two pieces of cardboard 1.5″ x 1.5″. This section will be the part that holds the motor. simple electric propeller car Step 2 – Attach The Axle Cut two straws and glue them to the bottom of the cardboard. Make sure the straws are wider than the base which will help keep the wheels from contacting the cardboard. simple electric propeller car

Insert the wooden skewers or dowel rods into the straws leaving about an inch sticking out. simple electric propeller car

Step 3 – Prep The Wheels The fun thing about this project is that you can get really creative with most aspects of the build. For example, there are countless materials that you can repurpose to create the wheels of the car. Here are a few examples: Bottle Caps Plastic Cup Bottoms Foam Cup Bottoms Pringles Can Top/Bottom Gatorade Bottoms 5-Hour Energy Bottle Bottoms

The most precise way to do this is by using a drill and drill bit. You can also use a razor blade and cut a tiny “X” in the bottle cap.

NOTE – If you want to reuse the motor for other projects, try using zip ties instead of hot glue. This will make it much easier to remove at the end of the project.

Step 9 – Connect The Wiring The first thing you want to do is a test to make sure the propeller is spinning in the correct direction. Add the batteries to the holder and touch the black wire to one terminal on the motor and the red wire wire to the other. Verify the propeller is pushing air away from the motor. If it’s not, switch the wires. Now go ahead and put the black wire through the terminal hole and twist it a few times. If you want it to be permanent, you can solder the connection.

Push the stripped wire into the middle hole of the switch and twist a few times to secure. Take the other half of the red wire and strip both ends of it. Push one end of the red wire into the outer hole of the switch and twist to secure. Twist the other end of the red wire to the open terminal on the motor.
