Electric Race Car

This project is a simple small car that works. It takes some time to make, but it works well. First you need some information on circuits, current, voltage, resistance;

Volts is electric potential, movement is needed in order for electricity to do any work, electricity flows from high voltage to low voltage, - has less volts and + has more volts, load is a task, you don’t want to burn out parts by adding weight, short circuit resistor slows down current, and too much power + task= Boom!

Voltage is a difference in charge, current is the rate at which a current is flowing, resistance is the tendency of a material to resist a charge, current is measured in amps Voltage is measured in volts, and charge is measured in coulombs.

The materials and tool needed are; Hot Glue, tape, a cutting utensil, card board, a motor, a 9-volt battery, wire, a wire stripping tool, 2 6 cm axles, 4 wheels that fit on the axle, 2 gears that mesh and fit on both the axles and motor, Popsicle sticks, and (optional) 4 washers that fit the axles.

This car won't be any larger than 6 cm. by 18 cm., for it to work right.

Step 1: Cut the Cardboard

Take your cardboard and cut it to 4 cm by 14 cm.

Step 2: Make One Wheel Set

Take a wheel and a gear and put it on an axle.

Step 3: Put Axle In

Put the axle in the fourth hole down from the end.

Step 4: Put the Other Wheel On

Take another wheel and put it on the end of the axleA

Step 5: Set Up Motor

Strip the wire ends and attach it to the motor.

Step 6: Attach Motor

Hot glue your motor to the base, and make sure that your gears mesh.

Step 7: Add Front Wheels On

Take a wheel, and put it on an axle. Take that axle and put it through the front-most hole in the cardboard. Then attach the last wheel.

Step 8: Attach Negative Wire

Take your negative wire and hot glue it to the negative battery terminal.

Step 9: Attach Other Wire

Take your positive wire and temporarily tape it on instead of an on/off switch.

Step 10: Put Battery on Cardboard

Hot glue the battery onto the cardboard.

Step 11: Add Support

Hot glue three Popsicle sticks onto the bottom for support.

Step 12: Bundle Up Wires

If you have extra wire, bundle it up and you can secure it with a twist-tie.

Step 13: Test the Car

Take your car, attach the wire to battery, and watch the car practically fly. If it doesn't work try fiddling with the wires and gears.

Step 14: Final Product
