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)

This time The idea was inspired by the old carousel seesaw game, and the character of “Al-Kabeer” specifically the sentence “ألف من له تار في البلد يا كابير”, we will make “Al-Kabeer” dizzy every time we press the on button, and the game will emit four different lights.

Tool Chain

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

Software:

1. Tinkercad: To design the electrical circuit, make sure that all parts are working and simulate what will happen in reality.

Tools:

screwdriver to make holes and help me to assemble the components.
Cutter to cut the enclosure parts.
Wax gun to assemble the enclosure parts.
Arabic calligraphy pens to write the text.

Material:

Cardboard for the enclosure.
Wax for assembling the enclosure parts.
2 already prepared keychain with "al-Kabeer" character
Tooth stick to hold the key-chains and connect them to the motor

Components:

Hobby gear motor for the movement.

3-12 VDC - 190 mA

4 LEDs

Red: 1.8 VDC - 20 mA

Green: 2.2 VDC - 20 mA

Yellow: 2.1 VDC - 20 mA

White: 3 VDC - 20 mA

4 Resistors - 220 Ohm for LEDs
Breadboard to connect the components.
On/Off Switch.
5V Power-supply
Jumper wires + Crocodile wires

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?

At first, I started by taking the dimensions of the motor to take the appropriate midpoint on the container, then I drew a simplified sketch to imagine its dimensions and the final result using Adobe Photoshop.

Mode: Off

Mode: On

I used the Tinkercad to design the electrical circuit and make sure that all parts are working and simulate what will happen in reality. and I used the previously mentioned components.

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 started assembling the circuit with the following steps:

Connecting wires to the LED bulbs separately.
Connect the positive and negative wires to the power input.
Connect on/off switch wires.
Connect the resistors on the breadboard.
Connect the positive and negative wires to the breadboard with additional internal connections.
Connect the on/off switch to close the circuit.
Connect the motor wires and test them.
Connect the bulbs separately and test them.
Test Full circuit. and finally, it works well.

After that, I cut the cardboard and made the enclosure, at first I put the motor gear in the middle of the top panel and glued it with wax, then I put the on/off switch on the front and the power input at the back.
I installed the keychains on the toothpick with hot glue and fixed them manually on the motor gear, as they can be removed easily.
I decorated the enclosure from the outside by adding some writings and drawings.

installing the motor

installing the switch and power

installing the rest of components and assemble the enclosure with glue

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?

I helped Sharqawi by suggesting some solutions to a problem he was facing with laser cutting

I learned a lot about the RC-Cars from Thomas, while working in one team, and we won three times in the hackathon by virtue of the design he suggested.

Also, Fatma's suggestions for some recent modifications while assembling the car was very helpful.

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 avo meter was a good helper in troubleshooting, it helped me find burnt bulbs and exclude them.

Also, it was very difficult to get the 7-Segment to work and I watched many videos so that I could test it and turn it on.

Final Project

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

The idea of the final project is almost the same as the idea of this assignment, I will operate lamps and a motor at the same time, and it was a good opportunity to test this early.

WOW!

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

All the things I learned this week were new and I had never dealt with electricity like this before, I didn't expect to get to this point at all.

The thing that impressed me the most was that I turned on Seven Segment after suffering

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.
