Week 5

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)

Electrical hand fan

Assignment idea

I chose this idea because of the heat wave we are suffering from. This fan is a beautiful invention and I wanted to make a simple model of it.

Tool Chain

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

for design

Materials

jumpers

12v DC Fan

female plug adaptor

on\off switch

led

resistors

crocodile wires

cardboard

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?

Electrical hand fan

It is a fan that works directly with 5v electricity or via batteries. It refresh the user while emitting a light beam to indicate that it is working. You can control its operation using the on switch.

Here I installed the circuit on a tinker cad to make sure of the connections. I started connecting the LED with the resistor in series and connected it in parallel with the motor, so that the positive is with the positive and the negative is with the negative. After that, I connected it with the switch in series so that I could control the circuit. Then I connected them to the power supply.

After making sure the connections were correct and the circuit was working, I ran a simulation to make sure that each part was connected correctly and that the circuit would work in reality.

Here I made a sketch of the shape of the fan and imagined it and determined the appropriate dimensions and determined the location of everything in the design to start cutting and manufacturing.

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 step

I started to make the body of the fan by cutting the cardboard and collect it again with wax

second step

I assembled the entire circuit on a small board. Then I assembled it with Crocodile Wires and put it inside the body.

third step

I tested the circuit to make sure it was working and then put everything inside the body and closed it.

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?

The topic was a bit simple thanks to the application on self-practise videos.

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 problem

is that there were many components that were not on Tinkercad.

The solution

is that I searched for the closest things that I use and replaced them and this method worked

Final Project

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

This will help me a lot in using Tinkercad before connecting to the ground to avoid damaging any components and to make sure all connections are working properly.

WOW!

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

It's so amazing to get to the point where you're doing something that's always fascinated you and you now have the ability to do something like this.
