WEEK 7

TITLE : Makes holes in the PCB board uv.

METHODS:

At this week, we trying to make a hole at PCB Board by using a drill. After making a hole we check the connection using a multimeter. If the buzzer at the multimeter were not buzzing so that's mean there must be no connection between each other. As you can see the picture below of the this week procedure.
Other than that the component connection to the test to find out the current components in good condition or not.

To measure current with a digital multimeter it is possible to follow a few simple steps:

• Turn the meter on.
• Insert the probes into the correct connections - in many meters there are a number of different connections for the probes. Often one labelled common into which the black probe is normally placed. The other probe should be entered into the correct socket for the current measurement to be made. Sometimes there is a special connection for current measurements, and sometimes a separate one for either low or high current measurements. Select the correct one for the current measurement to be made.
• Set main selector switch on the meter switch to the correct measurement type, (i.e. current) and range for the measurement to be made. When selecting the range, ensure that the maximum range is above the expected reading anticipated. The range on the DMM can then be reduced as necessary. However by selecting a range that is too high, it prevents the meter being overloaded.
• When the measuring the current, optimise the range for the best reading. If possible enable all the leading digits to not read zero, and in this way the greatest number of significant digits can be read.
• Once the reading is complete, it is a wise precaution to place the probes into the voltage measurement sockets and turn the range to maximum voltage. In this way if the meter is accidentally connected without thought for the range used, there is little chance of damage to the meter. This may not be true if it left set for a current reading, and the meter is accidentally connected across a high voltage point.

CONCLUSION:

Although it is not as common to measure electrical current as it is to measure voltage, it is nevertheless and important ability to be able to measure current. Also knowing how to measure current to gain the best of the multimeter is also important. It is often necessary to know how to measure current using a multimeter. Current measurements are easy to make, but they are done in a slightly different way to the way in which voltage and other measurements are made. However current measurements often need to be made to find out whether a circuit is operating correctly, or to discover other facts associated with its current consumption.

WEEK 6

TITLE: Making etching pcb board uv.

METHOD: 

1.Buy the Printed Circuit Board (pcb) uv at Jalan Pasar.

• Cut the pcb using the machine cutter.

2. In the circuit drawing pcb express software. Then, print using film circuit that has peeped that.

Circuit that has peeped on paper film.

3. Pcb that has peeped print using uv panel.

• Tear off the black protection film on the board.
•  Attach the circuit artwork on the UV PCB board.
•  Expose the board in the exposure box for 60 seconds.

3a). Put the acid in the former and  put 5 seed acid. This proses to destroy  the cooper.

• Immerse the box after completely into developer liquid container.
• Agitate the board until the circuit can be seen clearly.
• Rinse and rub the board with water. 

CIRCUIT THAT HAS COMPLETED ETCHING.

CONCLUSION:

A PCB populated with electronic components is called a printed circuit assembly (PCA) , printed circuit board assembly or PCB Assembly (PCBA). In informal use the term 'PCB' is used both for bare and assembled boards, the context clarifying the meaning.

Alternatives to PCB's include wire wrap and point-to-point construction.PCB 's must initially be designed and laid out, but become cheaper, faster to make, and potentially more reliable for high-volume production since production and soldering of PCB's can be automated. Much of the electronics industry's PCB design,assembly, and quality control needs ae set by standards published by the IPC organizations.

 

 

 

WEEK 5

TITLE: Buying the electronic shop at Jalan Pasar Pudu Kuala Lumpur.

METHOD:

Jalan Pasar (or Pasar Road) in Pudu, Kuala Lumpur is a well-known street among the electronic enthusiasts especially for those who love to do electronic projects.

Today there are still some electronic shops available along this Pasar Road  though it seems most of them do not really devote in selling only the electronics components (i.e; resistors, capacitors, LEDs, IC aka Integrated Circuits) and electronic tools like soldering irons, solder suckers, digital and analog multimeters and so on.

Darson Electronics - One of the electronics shops at Jalan Pasar, KL.

Another electronic shop at this street.

CONCLUSION: 

Here at Jalan Pasar, the electronic shops there are also selling the audio system especially for the cars, PA system and alarm system. Apart from that item, CCTV cameras also among the popular products in this area.

If you are interested to buy the electronic components your choices are going to one of these shops below; all located at Jalan Pasar, Pudu, KL

1. Melectron Sdn Bhd, No. 40

Tel No: 03-21424748

2. MEGNUMTRONIC Sdn Bhd, No. 33

Tel No: 03-92226299

3. Standwell Trading, No. 32

Tel No: 03-9221 9179

Actually the Megnumtronics is also under the same umbrella with Melectron. Melectron is really serious about their business as they also have online (internet) presence.

To view what Melectron have to offer for you, just surf their Malaysia Electronic shop website. Now you know that the electronic shops at Jalan Pasar are still existed and they waiting for you if your needs are there.

WEEK 4

TITLE : Gong Xi Fa Chai and semester break.

WEEK 3

TITLE : Meeting the supervisor.

METHOD:

In the second week, we meet our supervisor, Sir Ahmad Zaki Bin Abdul Karim to discuss and guide us about our fyp project. He ask us to simulate the project is function or not. After that, he asked to do blog because it easier to upload and it simple. Therefore that,making a bolg also have a competition who make the blog most creative,interesting and simple to understand. 

CONCLUSION :

After discussing and understanding the Solar USB Circuit, we have decided to do this project quickly so as not to confused with the report when it has been peeped doing this project.

WEEK 2

TITLE : Overall operation USB Solar Charging.

METHOD :

INTRODUCTION 

• The usb solar can take the battery anywhere this is because the usb solar is using solar panel. Solar panel is using photovoltaics (pv). Photovoltaics is a method of generating electrical power t by converting solar radiation into direct currentt electricity.

• Any usb port can supply 5v up to 500mA. The usb standard specifies that a device may not more than 100mA untill it has negotiated the right to use 500mA, but apparently no usb ports enforce that requipment. This makes the usb port a convenient source of power for devices such as this charger. 

• A charger controller the rate at which electric current is added or drawn from electric batteries. It prevents overcharging and may prevent overvoltage, which can reduce battery performance or lifespan, and may pose a safety risk. 

•  Rechargeable battery it can be used on numerous occasions at very little cost compared to using non rechargeable, which has a limited life span and not cost effective. This almost trivial circuit may be used to charge a pair of AA or AAA sized rechargeable battery cells from sunlight.

CONCLUSION :

A solar power system can run all of your household appliances and is fairly portable if , for instance, to go camping and run an electric fan panel. Making a solar usb charger is easy and fun. This charger will allow you to charge or power any usb powered device with nothing more than light. Solar batteries that can be recharged with energy by using solar chargers.
