Week 18

Title : Gearing System

Objectives : To make the rotation of the motor more faster than the turbine

Contents : I wanted to make my output voltage higher than anyone expected.. therefore, i need to come out with a solution to make sure that this can be happened.. i had been thinking about the bicycle system, how when we cycling the bicycle, it can move faster although we cycle it slowly.. then i decided to buy a small and large sprocket to be attached to my turbine.. but something crossed my mind.. if i used the bicycle sprocket, it might give some weight to my prototype.. therefore, i need to think something else but have the same function as the sprocket.

 
Results : after asking an opinion from my friends, i got a new solution to it.. why don't i used a timing belt instead of the sprocket.. the timing belt is more light than the sprocket and have the same function.. 

i mounted the timing belt gear at the rod attached to my turbine..

and the belt is also suitable to be put on it.. therefore, i will stick with this decision..


Conclusion : the turbine is almost complete with the gearing system.. when the turbine move, the motor will move twice of the rotational of the turbine.. and when this happen, the output voltage also will be twice from without gearing system..

Week 17

Title : Horizontal Turbine

Objectives : To test the rotational of horizontal turbine

Contents : while i keep thinking about what to be used for my project, and what design should i made, i find a good component to be used as my blade.. i got this idea when i see my neighbor cleaned up his air-conditioner system.. i see a rotational blade inside it and i decided to go to the secondhand shop to get one for my project..

this turbine got a narrow gap between its blade and hopefully it can trapped air with full power.. but the most difficult task is to broke it down.. i need to unscrew all the screw but i got less equipment to do so.. therefore, i decided to go to the welding shop to borrow their equipment..

Results : after finished unscrew the parts, i got that turbine and this is how it looks like..

but, i got another task to do.. the base for the turbine need some alteration.. luckily i am at the welding shop, so i ask the worker to help me to alter it back.. and the worker also put a rod at the middle of the turbine to hold it.. thanks for helping me dude..

Conclusion : i think i will stick with this turbine and will make the turbine spin with ease in a slow wind.. please pray for me..

Week 16

Title : Ordinary Wind Turbine

Objectives : To test the current design of wind turbine, whether it is the best or not..

Contents : i had doing some research regarding the wind turbine that popular in the country with strong wind blow like Denmark.. The design of it just an arrangement of the blade mounted on the shaft..

Results : after go through the current design of the blade, i decided to make one for my project.. i used new CD for my tester, because if i used an old one, it might effect the entire system of the blade, because of the instability due to scratches..

i bought a polystyrene as the base for the blade and to hold it in its position.. then i try to make sure that the degree of the CD are best for the air to be trapped..

i tried to make it turn horizontally, but the air cannot be trapped with full power.. when i make it vertically, then it turns crazily.. but i do not want to make my project as simple as this.. so i decided to make this as my reference for the next design.

Conclusion : as a conclusion, all that i had done for this week will become my experience and i will use it as my reference regarding renewable energy..

Week 15

Title : New Concept

Objectives : To test new concept about wind turbine

Contents : I had opened a webpage regarding my wind turbine design.. and I had found out something amazing.. The blogger used a plastic bottle to make a wind turbine.. The steps to do it are very simple but interesting.. Therefore, I decided to give it a try..

Results : After get a rough time cutting the bottle to get a good shape, I had made 2 bottle that can turn when the wind blow..

 for the white bottle, i had made it to open outside from the bottle.. so it can attract the wind.. for the green bottle, i had made it to open inside, and the results are more better than the white bottle..

this is the closer view of the green bottle.. i put the sellotape to make sure that the position of the bend side are hold in it position..

i made a hole at the cap of the bottle, and put a wire through it.. and it turn smoothly with slow wind.. but unfortunately, it is not suitable for my project.. this is because, when the wind blow, the bottle also swing, and it reduce the turn of the bottle..

Conclusion : i need to make a new design for my project.. i cannot proceed with this design because of the swinging of the bottle.. i had put some weight at the bottom of the bottle, but it just slow it down.. so the next entry, i will show u all my new design..

Week 14

Title : Base for the project

Objectives : to find suitable base for my development of renewable energy using wind's project

Contents : at first, i had buy a 45cm x 30cm clear acrylic sheet or we called it perspek.. it is designed to be a base, but it is not strong enough to hold a project.. after buying and testing it, the prespek broke  into 2 parts... 

 
Results : after doing some research, i decided to buy a wooden base to be my base.. I'm not buying an ordinary wood, but a drawing base.. so, it quite nice to see..

Conclusion : now i proceed with the wood to become my base.. i hope that i will not buy another base.. haha

Week 13

Title : Multimeter

Objectives : to find a suitable multimeter to attach to the board

Contents : for my project, i have to display the value for current or voltage that i get from the moving of magnet inside the solenoid.. therefore, i had walk around Jalan Pasar to find that multimeter.. it is difficult for me to use existing multimeter that is huge and heavy..

 
Results : after taking some consideration from friends, i decided to buy digital multimeter that can display the voltage that i get from the movement of magnet inside the solenoid..

this multimeter i bought for about RM25.00.. this multimeter can vary from 200mV to 200V.. it is suitable for me because my output voltage depends on the power of wind.. if my output voltage during presentation is low, so i can vary the setting for my multimeter at 200mV..


Conclusion : this multimeter need external supply of 5V.. therefore, i have to buy at least a battery to make this happen.. but in my mind, i would like to use an adapter to power it up.. so, i have to go now and buy.. see u soon...

Week 12

Title : Solenoid Part 2

Objectives : to buy the iron core and make it become solenoid

Contents : after doing some research last week, i had decided to use 2nd hand iron core that i get from unused transformer.. the thickness of the iron core is quite small and related with what i want to use.. therefore, i had make some adjustment to the transformer..

 
Results : the transformer is from parts of personal computer.. below is the pictures of the iron core that i had been used..

after pull out the iron core from the transformers, this is the results..

Conclusion : this iron core i will used for the rest of the project.. i hope that this project will succeed..
