Week 5- Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

Yes, I am still deeply in love with energy, especially renewable energy. That’s why I came up with the idea to build wind turbines to generate electricity from them.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Tinkercard software

Scissor, Glue gun, Cardboard,& Yellow glue

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

In the beginning, I started by drawing the design on Tinkercad, where I placed the resistor in series with the LED to reduce the incoming voltage. Then, I connected it to the motor.

After that, I removed the motor and replaced it with a power source, simulating the electricity that would come from the motor when in motion, at a value of 5 volts , then i connected the motor to them in parallel

Next, I added a multimeter to measure the current passing through the LED, as well as the voltage across the resistor when applying the 8 volts.

added the button (in real is on/off switch ) with the power supply and then with the motor and resistance

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

First, I started building the prototype structure by making the fan blades. I created a thick circular base and attached the blades to it using glue. Then, I built the shaft that supports the fan body with the motor, placing the motor inside a cardboard casing. After that, I constructed the house frame, secured the LED inside with tape, and covered the roof with white paper.

Next, I began assembling the electronics: The LED was held with crocodile wires, and I extended two jumper wires from them to the breadboard. I connected one end of the resistor to the (+ve) leg of the LED and the other end to the button that connected to the (+ve) terminal of the power source. The (-ve) leg of the LED was connected to the (-ve) terminal of the power source.

For the motor, I used two crocodile wires and two jumper wires, connecting them to the on/off switch and negative terminals of the power source (5 V)on the breadboard. This set up the motor in parallel with a 330-ohm resistor and an LED connected in series—preventing the LED from burning out

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

Yes, I faced challenge, issue: the motor wasn’t running because I had connected them in series, so the voltage reaching the motor wasn't enough to move it. Only the bulb was lighting up.

I went back to Tinkercad to redesign, checking and calculating the voltage going to each component. Finally, I decided to connect them in parallel—and it worked! Both the motor and the LED functioned together as intended.

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

I can use the knowledge of electronics to prepare the final project for the fabrication process also I can use online sources to choose the outline of my design .

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

The coolest thing for this week was the sumo car race
