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.
Cut the Cardboard
Take your cardboard and cut it to 4 cm by 14 cm.
Make One Wheel Set
Take a wheel and a gear and put it on an axle.
Put Axle In
Put the axle in the fourth hole down from the end.
Put the Other Wheel On
Take another wheel and put it on the end of the axleA
Set Up Motor
Strip the wire ends and attach it to the motor.
Attach Motor
Hot glue your motor to the base, and make sure that your gears mesh.
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.
Attach Negative Wire
Take your negative wire and hot glue it to the negative battery terminal.
Attach Other Wire
Take your positive wire and temporarily tape it on instead of an on/off switch.
Put Battery on Cardboard
Hot glue the battery onto the cardboard.
Add Support
Hot glue three Popsicle sticks onto the bottom for support.
Bundle Up Wires
If you have extra wire, bundle it up and you can secure it with a twist-tie.
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.
