I decided to deconstruct the Thunder Tumbler, a remote controlled toy car.
On the underside of the car I noticed 4 screws, two keeping the battery pack in place, and another two connecting the front plate to the rest of the car.
I saw that there were two screws holding on a back piece however, they were not the only screws holding it on. In order to get to the other two screws that were holding it in place i had to remove the two back wheels.
Removing the back piece revealed the motors.
There were three screws on each side holding in the respective motor cases.
There were two screws on the top and three on the bottom holding the case together. Inside the case was a small system of gears that would rotate the wheels when the motor turns.
The last things to remove before being able to take out the circuit board were the contacts with the battery pack.
In order to remove the circuit board from the car, the antenna had to be removed from the circuit board. Attached to the circuit board are two red LED’s as well as two motors. The LED’s turn on when the car is turned on and the motors(in addition to the gears) are used to control the rotation of the wheels. There was an antenna connected which received information from the remote control. On the top of the circuit board there was a switch, a capacitor, and multiple transistors.
