Cheking the inside part

 Now that we have finished our Power Supply It s now the time to check our hard worked project.First, Madam Arrianne checked the inside part of our project.

Cheking w/ dynamo.

             Then after checking we have to test to a dynamo, and it worked!

The Overthrowing

Next is the overthrowing of our Power supply to check if its working ,then after that we have to test it again if its working and it did not changed!, it's still Working ! ..

Putting the plug

"The Finishing Touches"
      After the very hard part we are now on the finishing touches for the project. Here we put the positive(red) and the negative(black) terminal.Then we put on the plug and it must be knotted so that it will not be pulled easily.

Putting the terminals

         We put connect the plug to the fuse and the switch.And lastly, then we put a screw on the transformer so that it will not move easily. We put the cover and its done at last ! .

"The Putting of wires in the Transformers and Putting holes on the Case"
       This day I think was the hardest day of the project, because we have to be careful on the connection of wires. First, we putted holes on the front and back of the case, then we move on to the connecting and soldering of the wires on the switch selector and on the transformer.
To start this, we connect the wires of the selector switch We skipped the "zero volts"  then connect the remaining volts of the selector to the diodes ; because its more complicated we have taken much time on it but we manage to finish it. Next is the Wires for the on/off switch and for the wires in the transformer and for the terminals, this is more simple than the first one because it has lesser wires to be soldered.
-Input = 220v
-Output = 4.5v

-3v connect to 3v feet of the transformer(output side)
-4.5v connect to 4.5v feet of the transformer(output side)
-6v connect to 6v feet of the transformer(output side)
-9v connect to 9v feet of the transformer(output side)
-12v connect to 12v of the transformer(output side)
We solder it after connecting the selector to the transformer.
    

The Transformer soldered to the other components.

"The Soldering of the Anode, Cathode, Capacitor and Resistor "
              On this day, we  have to work on our 'PCB' with the anode, cathode, Capacitor, and the Resistor. First, We put the 2 anode, then the 2 cathode, next is the 2 capacitor the the resistor(The resistor has no polarity so it depends onto both of us to put the resistor on any position) for the current to flow.







 Me and my partner started to solder out 'PCB'. "The soldering iron must no be too hot and not to warm before using it onto the components", Then I cutted the excess wire of the components.

  Then I cutted the excess wire of the components.

"Drilling to smoothening"
       After the soaking of our 'PCB' the next job to be done is drilling. And I'm the one that is tasked to do it. Drilling is not an easy job because Firstly, its my first time to do it , and the drill bit is shaking, but after all, i survied and finished my job :D .


        And after an exciting drilling my partner Aprille, smoothen our 'PCB' using sand paper and eraser.

The soaking

"Soaking to Wiping"
            After the cutting of the excess masking tapes on the 'PCB', me and my partner started to soak the designed 'PCB' on our container with ferric chloride on it.

Removing of tape

Then after 30+ minutes we took the soaked 'PCB' and washed it with running water, then we wipe our 'PCB' with a clean cloth then  we pulled the tape to see the finished design and then we passed it to madam arrianne.

The finished design

The outcome of the designed PCB.

"Smoothening, Tracing and  Cutting"

The smoothening

After the instructions of madam Florendo, we started to give a shot to our project by smoothening our 'PCB' using sand paper and eraser.After that, we covered our 'PCB' with masking tapes and put on the xeroxed design and a carbon paper on top of it for our design to be transferred to the masking tape. As said, we are tasked to transfer the xeroxed design to the masking tape.

Aprille tracing

                                        Aprille tracing for some minutes.

Me cutting

                    Then,  I'm tasked to cut the excess of the traced design  that is not needed so that the design of the 'PCB' will be illustrated clearly.
