Week#4- Journal

Ideation

buzz wire

The task was to design a circuit that contained an on and off switch for the entire system and had two different forms of output, such as sound, light, or movement.

I found this game to be popular and simple to meet the standards and I found it nice and fun if you make it.

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?


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 assembled the parts of the wood and made holes in it on both sides, using a drill to pass the iron wire through them.

Then I painted it with white wood paint and left it for 2 hours to dry.

For the handle I used a piece of foam and carved it with sandpaper, then inserted an iron wire with a closed loop at its end.

Then I prepared the electrical circuit, brought the board and connected it to the buzzer in parallel with the LED.

Where the positive terminal of the buzzer is connected to the positive terminal of the LED and the two are connected to a wire coming from the power source.


The negative end of the LED is connected to the resistor

The other end of the resistor is connected to the negative terminal coming from the power source and to the negative terminal of the buzzer

Before inserting the positive wire from the power source to the components, it must first pass the on-off switch


Then, after completing the circuit, I took the negative side out of the buzzer and connected it to a copper wire wrapped on the iron wire fixed in the wood.

I connected the negative terminal of the power supply to the iron wire on the handle


Thus, when the iron wire comes into contact with the handle and the installed iron wire, the circuit is completely closed and the current passes and the buzzer emits a sound and the LED lights up.

-I used a 5 volt power supply because the buzzer operates at 3 to 5 volts

The red LED is at 1.8 volts

Therefore, the 5 volt power source is sufficient to operate them. Therefore, I connected it in parallel so that only enough would pass through each of them and to avoid the entry of an extra volt to an unbearable component, which would burn.


I made the box in advance from craft paper

Unfortunately, I did not document the steps at that time, but I did a search on the Internet for how to draw individuals for a box

And I drew the individuals on the paper and I made paper folds according to the lines only, then I put the long wires on it, and then I put the board in another box and fixed them in each other using wax

I made holes for the switch, the power supply wire, the LED and the buzzer.


As for the second box, I also drew the individuals on the Internet, and I marked it on paper, and I cut and made the folds

With the addition of transparent plastic paper to see the LED light.




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?

My colleague Ahmed Abdel-Fattah has shared with us the game that he implemented on Slack and it was Buzz Wire as well

At that time I had a problem connecting the switch in the circuit and I asked him about it and he helped me and explained the steps.

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 had a small problem, that the iron wire I used was thick and had some solder in it

Therefore, it did not conduct electricity well.I solved this by using larger wires and cutting them to remove the copper tip and I wrapped it on the iron wire several times to conduct the current well

I faced a problem after making enclosuer for components, which is that the wires vibrate from their places and are unstable when they are pulled together and collected in the small box, so the LED did not work

I checked the circuit more than once and was sure of everything, but when I put it in the box, it didn't work. I will try to solve this when I go to the lab. He does not like to fix these wires with wefts because the board is not enough


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?


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.
