Week 26

Title : last testing

Objectives : to test the last time

Contents : after finish with my design and shape of the turbine, i got less time to test my prototype.. i does not have enough time to test it at the kite field, so i just using the table fan to run the test..

 
Results :

Conclusion : this result shows good result.. I'm happy with that..

Week 25

Title : new improvement

Objectives : to attach new improvement to the turbine

Contents : the current turbine is in vertical shape and requires large spaces.. so i change it into horizontal shape and put some new invention that never be done before,  an air trap mechanism..

Results : after measuring the length and the width of my turbine, i started to cut the perspek that i had bought before.. the perspek will be placed at every corner of my turbine..

Conclusion : this new invention will make sure that my turbine will move faster than without the air trap mechanism..

Week 24

Title : Changes in Concept

Objectives : to test various ways in achieving objectives

Contents : i had made some new improvement in my way of achieving my goal.. i had change the bearing from using cradle bearing into scooter bearing.. after doing some research and visit to the bike shop, i decided to use one of this..

 
Results :

Conclusion : this is my first try.. so i hope that my blade can rotate with ease.. Aminn..

Week 23

Title : too heavy and tall

Objectives : to adjust the length and weight of the blade

Contents : i had measure and test my blade, but unfortunately, it is too heavy and long.. i need to make some alteration.. the blade cannot be like this.. if it continue like this, my turbine will not rotate in low wind..

 
Results : so what i had done is, i cut my blade into half.. that's mean that i cut the length and weight into half too..

Conclusion : this turbine still can rotate in low wind and very cute. hehe

Week 22

Title : testing again

Objectives : to test the final blade

Contents : after undergoing some cleaning process, i tested back my turbine to make sure that it can rotate.. and if not, i got enough time to adjust it back..

 
Results :

 

i try to make the turbine to stay at the bottom and the holder is at the top.. but the weight make it harder to turn with ease..

 

then i try to rotate it, make the holder to hold the whole turbine.. and it make some good results.. the turbine move faster than before..

Conclusion : i start developing the turbine based on new discovery today.. so i hope that there is no more changes to be made..

Week 21

Title : "Room Service"

Objectives : to clean-up the turbine

Contents : i go back to the welding shop to use their equipment.. my blade got some dirty things in it, so i went to use their air blower..

 
Results :

Conclusion : now my turbine is clean from all the dirt things.. it can rotate more faster than before.. yeay..

Week 20

Title : DC motor

Objectives : to choose the right DC motor to be used as the generator

Contents : everyday i search the internet to allow me to find the motor with higher voltage but low revolution per minute.. but my search returned to zero results.. if i wanted to use motor from remote car, it has low voltage with higher rpm.. it is not suitable for my project because i need high voltage with low rpm.. then i go to visit Jalan Pasar to find the motor.. but unfortunately, the seller does not know well about the motor, and plus, there is no label on the motor to indicate its characteristics..

 
Results : the best motor is magnetic tape drive which can be found in computer mainframe from era 80's from Ametek production.. but that motor hardly to be found nowadays.. i had search on mudah.my about that motor but it is sold out.. so, i had to choose other motor.. then i found an old printer in my house.. i decided to unscrew it and check the motor inside it..

after unscrew all the component, i had found out there is three motor inside one printer.. and all the motor operate in high voltage up to 12V but in a low revolution per minute..

the left one cannot be used because it had 4wires out of it.. besides, the turns of the motor also having stepped and that is not suitable for smoother rotation.. the right one operate in 12V and have low rpm.. i decided to use that one but unfortunately it is already not functioning.. so i got no other choices, i used the middle one.. 

i had mounted the smaller gearing system at the end of the motor, so that it can be connected to the gearing system attached to the turbine..

Conclusion : this motor can generate about 4V when i turn the motor with my fingers.. this is great.. i hope when everything complete, the voltage generated will be at least more than 5V and can light up a bulb..
