Discuss how to present

Today we meet up together and discuss for our presentation. We need to give a presentation which about 10 minutes and demonstrate our circuit for 10 minutes too. It’s mean that each of us need to present about 5 minutes for our project and the demonstration for the circuit we will do together. Therefore, we divided to each other a few subtopic to present :
a) Introduction
b) Objective/Problem Statement
c) Circuit analysis
    - The component function
    - The flow of the circuit/How the circuit work
d) Conclusion

Part a, b and c will be present by hilmi and part c will be present by me ^^

Presentation Slide Show

We in the end of our project now, today we just complete the slide show for presentation. This slide will sum up all the process going through during the project happen. Or we can just say the summary of our report.

So, that all and tomorrow will be our last update.

Report Done!!

 Today, after worked like mad man, we finished doing our report and compile our works to become a complete full report. So, we just printed it out and binding and just wait to send the report to our course coordinator Pn norhana on Monday. We think we almost done 90% of our project and still ahead of due date schedule.

So we can chill a bit and prepared for our final exam.  

Demonstration by the other group of member

Today we went to see the other group demonstrate their experiment to us. The reason why we needed to see their group demonstration is to improve our skill in troubleshooting. Besides, the main purpose to do so is to build our critical thinking. Critical mind can make us to be a better thinker, a reasonable person and decision maker person. Hence, we need to comment what had been done by the other groups during their demonstration to us. We even judge them through their attitudes by asking them how was the project work and each components function. Below is their working breadboard:

Of course, the other group will also comment to our mistakes during our demonstration. All of those comment will be written to a piece of paper and pass it up to our lecturer.   

Gather Information For Report

Today, each of us busy finding the information for report. The hardest part was to find the information about percussion synthesizer background and application. We google through web and yet not gained so much information. So, we need to take little part of information from various website to combine it becomes nice and short summary. Other than that, we recall some problem we faced during this project that will be insert in our project report.   

For tomorrow, we planning to have group discussion with other group (attiya & haziq) to comment and gives suggestion to each other project work.

Discussion for report

After our circuit succeeds, now we move on to next phase, gather information to write a report. From the instruction given, we need to write maximum 8 pages report that including group name, objective and problem statement, background project, methodology, result and discussion, application of the circuit, and conclusion. To make things done in easier way, we separated the work between us equally and will have it compile after both of us finish do our own part.   

So,for today, that the plans, hope it will work well then.

Experiment Day

Today, we went to the laboratory and try to run our circuit. The first problem that we faced was we do not know how to adjust the value of the variable resistor. 

Although through the project question stated that we have to adjust the variable resistor value for R2, R3 and R4 when the switch is open. However, we do not know how to adjust the variable resistor when the switch is open.

Circuit diagram

Therefore, we can only try and error to test out the circuit. When we ran the circuit, we got the result where it was not the result we are expected. We thought the speaker will only sound when we press the push button,but in fact the result is not like that. The result which supposes to obtain was the push button was use to change the tone of the speaker and not to use it to switch “on” the speaker. The speaker will be switch “on” once there is a power supply to the op-amp 741 and 386. 

We realize our mistake after we found this video:

Finally, after watched this video, we can conclude that the result we obtain was done successfully.
