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)
Earthquake Alarm Device
I was interested in this idea because I don't feel the earthquake when it happens
This model is considered a warning to all people in the event of an earthquake
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Fusion 360
Laser Cutter Machine
Cardboard
Wax Gun
Wire Cutters
Angle 90 iron
connecting wires
Adaptor 5 volt
Buzzer
Lamp
Switch
Breadboard
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?
Simulation OFF
Simulation ON
I opened the tinkercad website
I choose from a list Component ( Slideswitch - Buzzer - lightblub - power supply 5 voltt Because the lightblub and buzzer work on 5 volts)
Connect the ends of the components using wiring
The lamp is connected to the buzzer in parallel
Because in a parallel connection, the voltage is constant and the current is split
I used simulation to make sure the circuit worked

Front
Right
I drew on sketch paper and put the approximate dimensions of the design, then I started drawing on Fusion 360
After completing the drawing of the three projections, I converted the design into 2.5D
Then I started putting the sides together to make sure they fit together
Then all parts were exported in DXF format.
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 opened the design in CorelDraw
- All parts collected on one page
- Adjust cutting Power = 30, Speed = 10 , frequency = 500
- The file was sent to the machine
- I put the Cardboard inside the machine and then set the Zero axis point
- Click on the play command in Machine
- Gather all the parts together and use the wax gun
- The circuit is connected as in the tinkercad diagram
I connected the wires as in the circuit diagram shown earlier
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)
After locking the device for the first time, it did not work
This is because the wires are not connected well in the Switch
I checked the connections again and discovered the cause of the malfunction
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
