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)

I was looking for inspiration on YouTube and came across a video with several ideas. I chose to make one of them: a fan — basically an air cooler in a box

Tool Chain

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

Here's what I used to build my circuit :

I used Tinkercad to build my circuit and run a simulation to test if it works or not.

I used a breadboard to properly connect and integrate all the components in the circuit

I used a 5V power supply to provide power to the circuit

RED LED(OUTPUT)

A push button to control the circut .

Added a a 220Ω resistor to prevent the LED from burning out by limiting the current

Since there is no fan component in Tinkercad, I used a DC motor instead to serve the same purpose in the simulation

(OUTPUT).

5v adapter ( Because both the LED with resistor and the DC fan operate safely at 5V, so a 5V adapter was suitable as the power source)

(INPUT).

Here's what I used to creat the outer casing :

Cardboards

scissor

solid tape

LED

BREADBORD

ON\OF Switch

wires

resistor

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?

RED LED

(OUTPUT)

(OUTPUT).

(INPUT)

(INPUT).

Tinker CAD :

At the beginning, I gathered all the required components in Tinkercad to start building my circuit connections

After that, I began wiring my circuit, using red wires for negative and black wires for positive

I started the wiring by first connecting the positive and negative terminals of the power supply, so I could then arrange and connect the other components

I connected the components in parallel to ensure they share the same voltage while operating independently AND Current splits between them.SO THAT If one fails, others keep working.

Next, I placed all the required components, connected them in parallel, and tested the circuit through simulation.

breadboard :

Finally , I connected the LED, the fan, and the power source on the breadboard in real life to test if they were working. Both the LED and the fan worked properly.

After that, I used crocodile wires to connect the switch in the circuit, allowing me to control its operation.

I connected the components in parallel to ensure they share the same voltage while operating independently AND Current splits between them.SO THAT If one fails, others keep working.

Then I cut my cardboard to shape it like the fan box I saw in a YouTube video (or at least I tried 😂) and placed all the components in their positions

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?

Tinker Cad :

Gathered all components in Tinkercad to prepare for the circuit.
Connected the power supply terminals (positive and negative) as the starting point.
Used wiring: red for negative and black for positive.
Added the components and arranged them in the circuit.
Connected the components in parallel to complete the setup.
Used a breadboard to organize and connect everything properly.
Added a push button as a control component.
Connected an LED with a 220Ω resistor to prevent burning out.
Used a DC motor instead of a fan for the simulation.
Ran the simulation to test if the circuit worked.
(I connected the components in parallel to ensure they share the same voltage while operating independently.)

video of simulation

Cardboard:

I first started by preparing my external box, making openings for the fan, one for my switch, and very small holes for the LEDs.

And then, on the side, I made an opening for the power input or adapter that will connect to electricity.

First, I connected the power source to the breadboard — the positive rail and the negative rail.

(I considered this as an INPUT ).

Then I added the LED with the resistor to the circuit, and it worked fine.

( first OUTPUT).

Then I connected the DC fans in parallel, and they all worked well.

(Second OUTPUT).

the components were properly mounted(wired ) together inside the enclosure box to ensure the device is organized and functional

video of simulation

Connected the LED, fan, and power source on the breadboard to test if they were working — both worked fine.
Used crocodile wires to insert the switch in the circuit so I could control it.
Cut the cardboard to make it look like the fan box from a YouTube video .
Placed all the components inside the box in their proper positions.
(I connected the components in parallel to ensure they share the same voltage while operating independently.)

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

I had a problem with how to insert the switch into the circuit, and one of my peers explained to me how to connect it correctly. After that, it worked successfully.

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?

The wires that were supposed to connect the LED to the breadboard were too loose on the LED legs, so they kept disconnecting. I realized the problem was with the wires, and when I replaced them with new ones, they fit well and worked properly.

Final Project

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

Learned how to connect and organize components on a breadboard.
Gained experience using resistors to protect LEDs.
Practiced adding control elements like switches.
Improved my skills in running simulations with Tinkercad.
Developed troubleshooting skills to identify and fix issues.
These skills will help me design and assemble the Stroop Box more effectively.

WOW!

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