Log
10/3/24: We connected the wheels to the axis then cut the chassis into a specific design. Approximately 5-10 Minutes.
10/24/24: We found the correct gears for the axis and motor and cut straws to glue to the chassis. Approximately 10 Minutes.
10/31/24: We attached the motor and axes with the wheels attached to our chassis with hot glue guns. Approximately 10-15 Minutes.
11/7/24: We noticed that the axis was out of place, so we removed the axes and the motor. Approximately 10 Minutes.
11/21/24: We switched out the gears for Solar Made gears and remove the motor holder to make sure the gears touched. Approximately 10-15 Minutes.
11/22/24: We attached pieces of Balsa wood for the holder of our solar panel. We also started on our website. Then, Justin’s dad tested the car with an AA battery, it turns out the wires are in the wrong place and that is why the car goes backwards. So, he switched the wires’ positions. We will move the motor to the other side so the axis gear won’t move. Approximately 5-15 Minutes.
11/23/24: We unattached the back axis to correct the gear’s position as it was facing the wrong way, so it the axis gear can’t move around. Then, we put the straws back into its position to glue the straws onto the chassis. Tomorrow, we will attach the solar panel and battery holder. Approximately 10-25 Minutes.
11/24/24: We tested the car with two AA batteries while fixing the axis to make sure they wouldn’t move. Afterwards, we attached the solar panel with a hot glue gun to test it again outside. While testing, we recorded our first trials of testing the car. Finally, Justin made the Video Features about Project WATTS. Approximately 2-5 Minutes
