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)

Card Board Fan

The Inspiration Image

I started searching on the Internet, and I was inspired by the idea of ​​making a cardboard fan from the picture above, and I started imagining the shape of an AC fan box and adding a 3mm Led bulb, and then I started working on my fan

Before doing the Fabrication, I started using the Tinker Cad software, I chose the electrical circuits section, and started making a simulation of the circuit shape needed to make the fan out of cardboard

And I connected the Power Supply with a power of 5 volts and a current of 93.5 Amps, then I connected the positive end to one of the terminals of the On/Off Switch button (Series connection), and at the other end of the button I connected the positive polarity to the small Breadboard, then I connected the Green led with the DC motor, ( Parallel Connection) to the positive holes in the Breadboard, then I connected the second end of the 3 mm Led bulb with a resistance of 220 ohms, and I connected the other end of the resistance to the negatively charged holes in the Breadboard, to which I connected the ground (negative) end of each of the power supply, as well as the second party for DC Motor, then I did Start simulation on tinker cad and the results were great.

Connecting in parallel ensures that the voltage and current intensity are distributed equally to all components inside the fan circuit, such as the motor and the LED, with a power of 5 volts and an electric current intensity of 93.5 mA. As for connecting in parallel, it reduces the intensity of the current and the strength of the voltage, which affects the work The motor that may not work due to the weak current and voltage, and it has been taken into account that a 220 ohm resistance is connected to prevent, The combustion of the LED cannot bear more than 2 volts 


The voltage that the motor can bear is 3.3 to 5 volts, and therefore the best choice for the power source is to be 5 volts, not 9 or 16 volts, because using an adaptor with a power of 9 volts or more may cause the fan circuit components to burn


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 took the Cardboard and started making the fan base

And I cut 4 boards measuring 15 *15 cm and taped each two together for reinforcement using a wax gun, then I made the side parts for the base of the fan with sizes 3*15 cm and I installed the base for the fan and I drilled the parts needed to put the ON/off switch button in addition to another hole. to the bulb and I connected them according to the Simulation and extended the electrical connections using Jumper Wires and the

 Crocodile Wires and I passed them through the neck A, the stem of the fan after I prepared it through Cardboard wrapped in a semi-circle, then I started to prepare an upper base for the upper part of the fan to install the DC motor as well as the Breadboard and the electrical resistance and the rest of the electrical wires, then I made Using the cover of a small water bottle, I attached the wings of the fan to this cover using an adhesive with a wax gun.

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises?  How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

220 Ohms

Resistor Mistake  

Mistake : 220 K Ohms 

Correction : 220 Ohms

On/Off Switch Button


Correction : Series Connection

During the implementation of the fan, I faced two challenges, the first of which is that when I was connecting the circuit on tinker cad, I found that the lamp did not work, and the second one was that when I was connecting the On/off Switch button, I found that the electrical circuit worked in all cases, and therefore the button On/off switch does not work, and for that I referred to the explanation videos and watched the video about the connection in series and parallel more than once, and after watching I understood the problem that I did not understand the difference between the connection in series and the connection in parallel, and after I understood the matter I experimented with tinkercad simulation and succeeded in connecting. As for the LED bulb, I made the appropriate electrical resistance with a value of 220 ohms, and then I found the bulb working without problems.

Final Project

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

Low Fedality Prototype

Upper Part

Base Part


I think that I have gained great skill in dealing with direct electric current (DC), and I have a great understanding of electrical circuits, and I can work with different electrical resistances based on the needs, and I have also been able to connect several components in one electrical circuit, whether in parallel or series, I think that All these skills are very necessary and basic and I will need them very much to complete the final project 

WOW!

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

The most enjoyable thing for me is that I was able to design Card board Fan, taking into account User Experience including simplicity, and aesthetic form, which is one of the most important customer requirements in products.

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.
