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 want to make a simple fan box, As I can control a simple fan with an on/off switch.

I used 7 segment display to act as the temperature of the room. As I can develop it later if the temperature increased, Fan Started.

This Design simulates Box fan, I searched on Google to inspire by a design which look like it, I was inspired by this design here.

Tool Chain

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

I used Tinkercad to design and simulate circuit first, and to check functionality of the circuit.

I used electric components that will serve me in my project.
1- 5 v DC Fan 2- Switch 3- BreadBoard 4- LEDs 5- 7 Segment 6- Resistors "330 ohm / 100 ohm"

7- Crocodiles 8- Adapter 5v

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?

Tinker cad simulation

At first, I started to make a quick test on components in tinkercad to make sure that connections are true before connecting components.

After that, I started to make the full circuit / project on tinker cad to check and make sure that it's functionality are good and behave as I want.

Simulation Final

Test 1 Simulation

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?

Testing components

After that, I began to add a switch and make it controlling power to the circuit by turning it on / off.

First, I started to check each element in my kit, So I can check that is works alone.

After That, I Connected another 7 segment and DC Fan In parallel to make sure that DC fan receive 5v and to make sure that there isn't a voltage drop because DC fan operating voltage is 5 v not less.

I Used adapter 5 v in my circuit to power the circuit with power needed and because of DC Fan operating voltage is 5 V. So, If I connect lower than 5v Fan didn't on .
And if I connect more then 5v DC fan and 7 segment will burn.

Test 1 Box Fan

Making Cardboard

Putting Components

Final Fan Box

This is Cardboarding Time, I begin to design cardboard for DC fan, I started to cut in material with dimensions of fan ,Switch and 7 Segments.

Then, I started to put each component in its position and make sure that power delivered to it clearly.

Connecting Section

At First, I Started to connect 7 segments to the power by using Female to male jumpers.
and make sure that I connect Common to cathode

I want to show 8 num in 7 segment. So, I connect pin A , B , C , D , E , F, G to Anode.

And the other 7 segment shows num 5, So I connect pins A , G , F , E , C to Anode.

I also want to connect DC fan. So, I connect the red jumber into Anode and the other black into Ground.

I also used crocodiles to connect LEDs. I connect the taller term into Anode and the other term in led into ground, And Don't forget to add a resistor (100 ohm at least) to save LEDs from burning.

Final PC Fan Cardboarding

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)

Breadboard Problem

Problems

At First, 7 Segment didn't show anything although that I connected its anode and common.
I searched for this problem and I'm sure that my connections is true.
Finally, I got the real problem , It's the Breadboard and I solve it by changing the breadboard to another one as shown because the Breadboard can't connect correctly.

Final Project

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

In this week, I learnt alot about electric circuits and wiring and how to make a smart device look like my PC fan.
I thought that will help me in designing and preparing my final project circuit and I will add a power switch to control power in my final project to switch it on / off at anytime

WOW!

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

This Week, I learnt how to deal with electric components and How to make a smart device that I put components and connect it with each others with a cardboard to make a smart device at final.

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.

My Great Team, Number one :)

RC Car Makethon

This Week, We made a cool sumo RC Car "سابق 1" from scratch. First, We design it on fusion 360 , laser cad and begin to fabricate it on laser cutter. putting electrical components "DC motors , caster ..etc" .

Then we started to battle with the other teams with their Sumo RC Cars and we beat all of them and got the 1st place.
