Week 14 (FYP2) : Poster

Hi, this week is the week of the presentation day. So i had designed my poster, and showed it to my project advisor. She did correct my poster in term of the design and wording.

Wish me luck for the Presentation Day

Week 13 (FYP2) : Result and Analysis

Hi, this is the last week before the Presentation week. So i need to collect some data for my project.
I had measured the output voltage of the solar panel from 8am until 6pm.

The figure above shown the voltage reading of the solar panel, at 11am.

Time	8am	9am	10am	11am	12pm	1pm	2pm	3pm	4pm	5pm	6pm
Volt	9.57	10.23	11.8	13.02	13.9	13.5	13.2	12.43	11.29	10.18	9.02

Table above shown the data i managed to collect.

Besides measuring the output voltage of the solar panel, i also did measure the power consumption of the LED bulb.

The load (LED bulb) was rated at 12.26V and 0.11A.

Week 12 (FYP2) : Troubleshooting

Hi, this week, i will be discuss about troubleshooting. Troubleshooting is a very important step, before you can present your project to your assessors. this is to prevent further humiliating, if the project not working.

For my project, i had found 1 problem, and it was related to PIR sensors. Upon investigation, the problem was because of the range of detection for the both PIR sensor. It was known that PIR sensor has long and wide detection range, so range of detection for both PIR sensors, overlapped with each other. To solve this problem, I used a cardboard, and cover the PIR sensors. This is to limit their range of detection.
 

Figure above shown the range of detection for PIR sensor.

I had used cardboard, to cover the PIR sensors, and limit their range of detection

Week 10 & 11 (FYP2) : Assembling the solar panel with the structure

Hi, this week, i will combine the post for Week 9 and 10 together, since it took quite time to get done the structure. In case you don't know what structure i am talking about, please check it out here.

Solar panel was assembled on the structure of the highway lamp post, and the connection was soldered.

Week 9 (FYP2) : Designing the structure

Hi guys. This week i had played around with SketchUp software, to design the structure of my highway lamp post. SketchUp is a freeware software, and very user-friendly. Even a noob like me, can use it :)

You can download it from here.

Two posts were designed, both for housing the PIR sensors. Both sensors is responsible for ON and OFF the LED bulb respectively. The circles are where PIR sensors will be. 

Update : I had met my project advisor, and she agreed with my design. Yeay ! 

 

Week 8 (FYP2) : Soldering the components

Hi, this week, i have soldered all components on the PCB. My skill a little bit rusty, because the last time i solder was when i was in Semester 3, for subject Electronics 2.

Since the PCB has been designed according to the schematics diagram, so minimal wire jumper was needed.

This is the look of the PCB after the components has been soldered on it.

Week 6 & 7 (FYP2) : Creating the PCB

Hi, sorry for late posting of the Week 6, because i was busy preparing for the Phase Test. So, i combined Week 6 and Week 7 under one post.

This week, i had create the PCB using layouts that i had designed using Altium Designer; and copper board. There were many step involved in creating the PCB.

Figure above shown the process of cutting the copper board. i bought an A4 sized copper board in Jalan Pasar for RM9.

Figure above shown the cutting process of the OHP sheet.After printing the PCB layout on a Overhead Projector (OHP) sheet, i cut it according to the size.

Align the OHP sheet which has the printed layout on the  copper board. Make sure the printed side was facing the copper side of the board.

Iron the OHP sheet onto the copper board. The heat applied by the iron, will cause the ink on the OHP sheet to stick on the copper board. Thus making the copper board look like the OHP sheet.

Dip the PCB into the Etching solution (Ferric Chloride solution, FeCl₃. The solution reacted with the unmasked copper, and removes the unwanted copper from the PCB. This process is called as Etching. The PCB was check every 10 minutes.

Now the PCB was carefully drilled, to make the holes, using drilling machine.

Picture above is the completed PCB.
