Intro: Electric Car
Today I am going to teach you how to create battery operated car. This vehicle is not remote controlled.
This project will require:
- Wood(I used Plywood)
- Limit Switch
- Gear Box with wheels attached( I got mine from a RC car that did not work)
Step 1: Cut the Wood
For this project I used 1 inch ply wood.
You will need these different dimensions(in inches):
- Four 7 x 1 blocks
- One 8 x 1 block
- One 3 x 4 block
Step 2: Putting the Rods On
You will need a 1/4 inch diameter rod with no threads that is 7.25 inches long, a 1/4 inch diameter 20 threaded rod that is 10 inches, and a wing nut that will have the second rod fit inside it. Then drill a hole inside the wood making sure it is symmetric. When drilling the hole, make sure that the rods are close. The rod with no thread should not move, so drill to a point on each piece of wood until it does not move. Before you put on the rod that is threaded, put the wing nut on it. Then put the four 1 x 7 inch blocks to create the main base. Congrats, you now have the breaking system.
Step 3: Screw the Rest of the Wood
Screw the wood on as see in the picture.
Step 4: Attach the Gear Box
Attach the gearbox to the 3 x 4 inch block. Then attach the wheel followed by a hex nut onto each side of the threaded rod.
Step 5: Attach the Electronic Components and Wire Them
Put the switch and the battery on the wooden block. On the front right corner, place the limit switch. I had to put a dowel in front of it so the wing nut could hit it. The reason for this is so that the car does no keep on moving and it stops. The limit switch stops the motor, so the motor does not grind. Then, wire the parts using the picture as a diagram. Congrats, you are done.
