UPDATE

WEEK 7

hello readers!
 Alright for now i just update a link. Just to show you that this link is helping me so much..!The link provide me a basic idea and also provide the way to do it....There is about 5 steps in making the thing. I enjoy the learning process very much!

WEEK 6

Title: Change in method in making the magic mat. No more solenoids.
Objective: To solve the problem by making it in another way

Content: Since I'm still can't thinking another way to do the mat...I decided to change my method in constructing the mat...The method that i used to have will be different from previous-which is different in terms of its (method). I am still using the electromagnetic induction but for this time the principle came from the alternator itself. 
Remember that my last time proposal, I used to have a project that can contribute benefit to the consumers. The project should not being noticed by people surrounding. Therefore, I am still make it that way. For this time, the method is easier than previous. And I hope that my present project will success. I hope so....

Here we are!

Based on the figure above, energy system can be divided into three types which is energy in, energy store and energy use. The energy that I wanted to have in my project is pedal power categorized as an energy in...The pedal power is actually the source of energy. Same goes to magic mat, whereby the magic mat is used pressure comes from people's steps. Later i will show you the sketching and the things I bought for this project. Power pedal construction is still in progress.....

What should I do?

Week 5

Stage 2:
 
Above is the image of my progress project where i found difficulties in making a smooth moving magnet. The magnet should be moving into the solenoid freely to ensure the electromagnetic induction's working....
 Analysis:
I do have problem in designing the mat. The thing stuck in my mind is on how the magnet could be move freely towards the solenoid. Based on my friend's opinion, i should make a rail for the magnet so that magnet can only moved straightly and smoothly. Furthermore, i should consider its case. The magnet should have case for sure. Besides, how i can to make sure that the magnet can move forward. By what kind of strength the magnet can be move? Not only the springs but i am very sure there is another way round. Wish me luck!

.......................................................
By the way below is the images of all the materials and components i already used.

Materials and components

Copper wire
Analogue Multimeter

Compass & Ferrite Magnet (7.3x1x0.8cm)

Clip wire

Plywood (13x17.5inch)

PROGRESS......

 FYP SEMESTER 2!

 WEEK 3

Stage 1:
  • Making the solenoids
 Materials used:
  1. copper wire
  2. tape
  3. wire
  4. scissor
Here are the video I had recorded. This is just to show that current deflected whenever the magnet is entered the solenoid.



  • Mat's Design
Materials used:
  1. Plywood
  2. Hammer
  3. Chisel (pahat)
  4. Glue
  5. Springs
Analysis:
Based on the video above, I can see that electromagnetic induction going to be work here. But in order to produce high output current, therefore the design of the solenoid must be seriously consider. Based on the video, the current only deflect just a little, only micro ampere. Thus the solenoids needs more turns in order to get the best result. The solenoid that i made is just only 500 turns so i need about 800 to 1000 turns. 
For mat's design, the plywood is taken because i need insulator type material in order to make a base. Do not forget that i used magnet in this project. Therefore i need to keep away all the conductors or material that may attract the magnet to the mat. Otherwise it may effect the result.

Conclusion:
I have to make the solenoid one more time and see the result either it can give a higher current.

.......................................................................................................................

Below is the image of the solenoid with 800 turns.

 Analysis:
The solenoid manage to produce high current. But even though it can, i am still facing problem to found out the result. The magnet needs to enter the solenoid for many times in order to get a result. As a result, i need to do again the solenoid. For this time, I knew that the solenoid's hole is big which mean i need to make it smaller. Then i have to do it again. Wish me luck!

TITLE:DC CONVERTER AND ELECTRICAL STORAGE FOR SHAKE-A-GEN (example)

CONTAIN: What is the shake-a-gen? Remember my previous post about how to make an homemade generator? So, the design has another external link about the storage of DC power from the AC generator. This generator is called an AC generator. This means that the voltage appearing at the two wires alternates between + and -, and - and + each time the magnet goes from one end of the can to the other. Based on the website that I found, they used a device which includes a few components to rectify the alternating current (AC) from the shake-a-gen, store it in a capacitor and convert it into a steady direct current DC. The output can be used to run a low power device. It is also wired to an LED which lights as the generator is moved and also for a little while afterwards. An LED can also be wired across the generator connections so that both the AC and smothed DC power can be observed.  Below is the diagram for shake-a-gen storage device.

Circuit diagram of shake-a-gen storage device
Shake-a-gen

ANALYSIS:
PARTS LIST AND TOOLS
4 x OA91 germanium diodes
1 x 10,000 uF electrolytic capacitor (16V)
two LED's (red and yellow say)
1 x 1000 ohm resistor
1m of twin wire (bell wire) to go from generator to the circuit
soldering iron and solder

CONCLUSION: This post may be helpful to improve my understanding.

SCIENCE PROJECT: ONE OF EXAMPLE MAY USED

TITLE: Science project could be used in developing the magic mat.

CONTAIN:This is one example that used electromagnet concept. It provides an idea in designing the magic mat. This is an AC electric generator which lights up a tiny incandescent light bulb. The generator is made from a hollow-ended cardboard box with a nail through the center. The box has many turns of varnished thin copper wire wound around, with four large magnets clamped around the nail. When the nail and magnets are spun fast by hand, the little light bulb lights up dimly. Below is the modelling of the project. 
ANALYSIS:As I can see here, the project is basically about the AC generator. And of course the AC generator can be converted to DC. For the magic mat, I will need it the most. Therefore, this project gives me some information and guideline in order to make some power conversion which is from AC power to DC power. Besides, all possibility in designing the electromagnet is also mentioned on the author's blog. It can be used as my reference later on.

CONCLUSION:This project helps me so much! Here the details of the project. You may see the link below...

Title: Presentation FYP 1
Contain: This presentation video covers the introduction and purposes of the magic mat. It also includes the methodology in designing the magic mat. Some simulation also provided where the three factors contributed to project's development. Let have a look at that video!
Analysis: After finish the presentation, the assessor has make some suggestion regarding the project. The suggestion is for magnet type that will be used in this project must be strong enough in order to give the best output. Therefore the magnet type of NdFeB has been suggested. It will take into consideration.
Conclusion:  For next progress, it should have a design of solenoids.
