Day 1:
I have finished all the brainstorming and have decided on my final product. Initially, I planned to construct an electric motor utilizing magnets, copper wires, and an aluminum can. It was a seemingly easy target as the tutorial was relatively fundamental. However, I went to consult with Mr.Michi only to be told that it was an impossible approach. Therefore, considering the complexity, I reorientated my target and decided to make an electric toy car.
Day 2:
I continued searching for divergent electric car designs and tutorials with coherent circuiting processes. After finalizing the outline of the invention, I began to collect materials. I also asked different teachers about the circuitry and the usage of additional wires. The circuit was relatively difficult to complete as I connected one battery to two motors and one switch. Subsequently, I completed an imperfect prototype of a functioning car, including the circuit. However, the batteries were noticeably overheating after short periods of time, which had to be solved by constantly substituting the battery. It was also physically harmful to any users, especially little kids.
Day 3:
We made some aesthetic improvements and added new components to enhance the car’s function. The overheating issue was successfully alleviated by connecting another battery to the motor. This improved the self-sustainability of the car and also permitted a greater velocity and stability of the movement. By rearranging the wires and distributing the energy consumption, the heating of the circuit was controlled to a manageable level.
