The first day was an introductory class. Mr. Andrew G. Bell, our instructor, talked about the

syllabus for most of the time. He briefed us about what were the expectations and the tasks that

we would do during the whole semester. After that, he explained us what equipment we are

going to use for the tasks. The directed us in how to keep our equipment and tools organized on

each bench, and he asked us to turn on the equipment on the top of benches to introduce us to

them and taught us how to use them so that we get a hang of it. In the end, he instructed us to

clean the benches after we are done with our tasks and where should each of the equipment be

put.

Resistor:

A resistor is a two-terminal electrical component that implements electrical resistance as a circuit

element. Resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias

active elements, and terminate transmission lines. They only consume power and can’t generate

it. Resistors are usually added to circuits where they complement active components like op-

amps. Resistors come in a variety of shapes and sizes. They might be through-hole or surface-

mount. They might be a standard, static resistor, a pack of resistors, or a special variable resistor.

Capacitors:

A capacitor is a two-terminal, electrical component. Along with resistors and inductors, they are

one of the most fundamental passive components. Its device used to store an electric charge,

consisting of one or more pairs of conductors separated by an insulator. A capacitor consists of

two or more parallel conductive plates, which are not connected, or touching each other, but is

electrically separated either by air or by some form of a good insulating material. A capacitor

generally releases its energy much more rapidly, often in seconds or less.

Inductors:

An inductor is just a coil of wire around some kind of core. The core could be just air or it could

be a magnet. When you apply a current through the inductor, a magnetic field is created around

it. The inductor is similar to the opposite of a capacitor. In series it will resist alternating currents

and let direct currents flow free. It’s like a bully component. It will mess with the alternating

currents. But the direct current he will let be.

Lab #5

At the start of the class we watch some videos on Safety of Soldering.

After watching the video, we were each asked to pick a circuit board and some components

which included resistors, LEDs (red and green), battery connecter, capacitor, OP Amps, IC

Sockets, and a translator.

Soldering all those components onto the circuit board was a bit untidy at first but, in the end, it

was quite easy for first time having to do soldering.

Once everything was soldered onto the circuit board, we would then connect it to a 9V battery

and test if it was working or not. To know if the system was working, we had to make sure that

the LEDs light up or blink in the manner; red LED first (far left side), green LED (from the left

side), red LED (from the right side), green LED (far right side). If was not in that manner than

we had make changes to the circuit to let it light up or blink that way.

Lab #6

This week, we were supposed to troubleshoot on the first circuit board we worked on with the

help Mr. Andrew G. Bell, our instructor. However, for some circumstances he was unavailable

and instead we worked on second smaller circuit board.

We started on our next project with a smaller circuit board which had components such as, red

LEDs, trimmer, translator, capacitors, resistors, and a battery connector. First, we had turn on the

soldering iron and pre-heat it. After that, we had to wear safety glasses and take some lead to

solder the components onto the circuit board. I started off by soldering the resistors on the board

first. Then I placed the trimmer on the board. Third came the translator and capacitor. Once I was

done soldering those, I soldered the red LEDs. Lastly, I soldered the battery connector. There

was a certain manner the red LEDs were supposed to light up or blink. Which was, that they

should blink from left to right and back again. If it was not blinking in that manner we had

troubleshoot it and see where we went wrong. To power up the circuit board, we had to connect

it to a 9V Battery.

Finished work. Instructions on how to solder everything properly.

This week, we started the class off by looking at the mulitism software and how the first board

we made was constructed on this program. After looking at it and going through the software,

our instructor had us construct the smaller flashing LEDs circuit board that we made the week

before using the multisim software.

Before starting the mulitism software, we had to look at other projects to see how the circuits

were constructed. While going through the other ones, we got to know how the first circuit board

we worked on was built using multisim. After taking reference from the previous ones, we had to

make the second one, which was the smaller flashing LEDs circuit board.

First thing to was to figure how much voltage does the circuit needs to run. It was 9V looking at

our own circuit board that we made. After looking at the resistors on the board, we had put the

right ones at the right places (two needed to be adjusted to 1k and the other two to 10k). Next,

the capacitors needed to be connected to the circuit. Then came the transistors, that had to be

connected (had to flip the components as needed). Next had to be the potentiometers that would

go to with the circuit (increment needed to be at 5% and the resistance was set up to 250k for

both). Lastly, the LEDs and the ground needed to be added to complete the circuit. Tested and

worked.

This week we were given different part and we had to figure out how to take it all apart and see

if it still works. It didn’t work at the time I took mine. Also, the part I had need to connected to

something or a computer to make it work. I google everything about that part but nothing came

up relevant to the part I chose to work on. However, I still took out all the components and

soldered back all of them in the right place where they were before.

For this lab we were each assigned with a lamp on which we had to replace the head of the

power cord of the lamp. First, we had to cut the head off and then strip the wires a bit for

soldering the new head onto it. We had to make that the neutral and positive wire were apart

from each other so that they would not touch. So, I taped the wiring separately first so that they

do not touch each other and then taped it again as a whole to make it look clean. I tested mine

and it worked perfectly.

For this week, we had to redo the previous lab since it was done the wrong way. Firstly, we had

to cut off the plug of the power cord. Once the head was taken off, we had to connect the positive

and neutral wires to the prongs. After that we had to test it to make sure it works. Mine worked.

However, this we had to do few other tasks also. We had to the whole power cord off and replace

it with a new one and also that, we had change the base socket where the bulb would go with a

new one. But, the lamp I was assigned to, the base socket was screwed together tightly and I

could not take it or the power cord out because I did not have adequate tools to take it apart.

Instead, I fixed another lamp of one of the student who did not come to class. I changed the plug

on that lamp also but, the power cord and the base socket was not changed on that either. This is

because the wires were glued with a hot glue gun and I did not have adequate tools for it. And

the base socket was not changed because the new base was larger than the one that was already

installed in the second lamp. Nonetheless, both the lamps worked after I changed the plug.

New plug installed (first lamp). Bulb lights up (first lamp). Plugged in (first lamp).
