Week 5 - Journal

Ideation

pen holder

The assignment for this week is making PROJECT with use 2 outputs and a power supply

https://www.jumia.com.eg/ar/mlp-mini-hand-fans
a simple Fan with led indication
power connected is RED and BLUE the fan is on
the case was made of cardboard and assembled with hot glue gun
the project was simple to use 2 outputs and a power supply
i choosed the 5v power supply to power both the rgb led and the Fan
i will connect because fan and rgb led on parallel and they are both rated for 5V

Tool Chain

tools

component :

5v power adapter as my power supply source
RGB Led light used the blue and red pins
2 Resistors 220-ohm
1 Resistor 330 ohm
3 pin Mini Slide Switch
a 5v dc Mini Fan
some male to male jumper wires
some male to female jumper wires
mini circuit
small BREAD BOARD

Software:

"For Design the circuit "

i used tinkercade to but the circuit and make sure i don't fry more components

Design/Preparation Process

"TINKER CAD" Software:

I have designed the circuit on tinker cad to see if is going to work or not
I used a 5v adapter to power the circuit.
I conneted the fan in parallel with the output
2 Resistors 220 ohm >>> for red and blue terminals in RGB led
1 Resistor 330 ohm >>> i found that the RGB led light is too bright so i added this to the cathode terminal to lower the intensity a little and it worked
I used a slider switch to control the whole circuit (ON-OFF).
started to simulate the circuit to figure out if it's going to work or not and it did work.

Development/Implementation Process

I used the small breadboard to make my project compact
Cardboard
had some troubles with the circuit but finally it worked as it should.
I used the cardboard box to cramp all components and made some cuts and opening for power jack and led and the on/off button and the fan itself and then attached the sides with hot glue
I also made a long hand of compact cardboard and passed through the fan wire.

Community of Learning

This week I with LAMA formed a team in wednesday's lecture but we had difficulties working on the required catch so I could see it and not hear me but we quickly solved that problem with Sherif's help and we did what was required of us
On Saturday, Me Hussein and Rowan formed a group and we were required to have several (installation of 2circui in the form of remote control - design of a car ON fusion360 - cut that car using a lasercutting )

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've had a lot of problems making the project curcit, and I've changed that over and over again until I get to the final solution,

and here's all the failed steps.

Final Project

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

Now I'm able to design a circuit for the final project.

WOW!

I tried to assemble circuits to see what will come out (this assembly is for the circuit up

look at this

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.
