Week 5 - Journal

Ideation

Inspiration

The idea for the device was inspired by a circular saw, but redesigned in the form of a table. This design enhances safety and provides more stability during use, making it easier to handle materials with precision. It combines practicality with a compact look suitable for home use or small workshops.

I used Tinkercad to simulate the circuit before implementing it physically. For the physical setup, I used jumpers, a socket (rosetta), crocodile clips, a small breadboard, an on/off button, an LED, a 5V adapter, a cardboard base, and a cutter.

Tool Chain

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

Crafting Tools

Card Board

Cutter

Glue Gun

Electronic Components

Jumpers

Mini Bread Board

Male-Male Wires

Single Red LED

220 Ohm Resistor

DC Motor

Software

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?

I designed a circuit to make the motor and LED work simultaneously using a switch and simulated it on Tinkercad. Here’s how I built it:

Set up the base: Placed a breadboard for connections.
Connect the LED: Positioned it on the breadboard and linked its positive terminal to the power source.
Add the motor: Connected its positive terminal to the same row as the LED.
Insert a resistor: Used a 220-ohm resistor between the LED’s negative terminal and the switch.
Install the switch:
- Connected one terminal to the LED’s negative side.
- Linked the other terminal to the positive row.
Complete the circuit:
- Connected the power supply’s negative terminal to the breadboard’s negative rail.
- Attached the motor’s negative terminal to the row after the switch.

Now, turning on the switch powers both the motor and the LED simultaneously.

I chose to use a 5V power source because the fan operates at 5V, while the LED operates at 3V. Therefore, I added a resistor to reduce the voltage reaching the LED and protect it from damage.

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?

I installed the blade and turned on the device. After completing the design process, I started assembling the components inside the box after putting it together.

Following the same steps used in TinkerCad on the breadboard we well get the same result.

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 asked about the challenges I faced while preparing the files, and the trainers played a big role in overcoming the obstacles.

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?

I faced difficulty in determining the positive and negative connections between the power supply and the switch, and how to connect them to the breadboard. I watched the videos multiple times and asked the instructor until I finally found the solution.

Final Project

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

This week, I learned how to design and simulate circuits using Tinkercad, troubleshoot issues with components like LEDs and switches, and assemble a functional prototype. These skills will be crucial for my final project as they enable me to:

Simulate and test circuits before physically building them, reducing errors and saving time.
Efficiently assemble components on a breadboard and integrate them into a functional design.
Incorporate custom design elements, such as cutting and shaping materials, to create a professional and practical final product.
Troubleshoot and optimize performance using tools like multimeters, ensuring the project operates smoothly.

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 I learned this week is how to simulate circuits on Tinkercad before actually building them. It’s a game-changer because it lets you troubleshoot and perfect your design virtually, saving time and avoiding mistakes.

Something I’ll never forget is how satisfying it felt to see everything come together physically after testing the design digitally. Watching a circuit come to life, especially when everything works as planned, is such a rewarding experience!

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.
