Oh yeah, he does a good job.
Don't know about the scammers thingy, I know he does give very good and useful advice. It might be for some certain people but you will surely pick something up.
Thanks bro!

Funny enough am in a situation like this now,
How long can I go!
Considering how much she means to me and how unique she is I'll go a very long way.

Ps
Those that say the're other ladies, so why waste time on one.
My answer- you haven't met the right girl that's why, if you do, no other woman in the world would mean nothing to you. (Save your sis, mom, aunt etc)

I don't know, I never bothered to ask. No matter how much it is, it will be enough for you, considering they feed you and give you accomodation.
Health, books(I think). Everything is provided for you. But I can ask a friend sha, when I see him.

Its free, nobody pays anything.
They pay you instead.
Its not as vigorous as it use to be. People don run away as they did in thoes days, its just like every other thing in nigeria. Changed!

homerac7: u have done a good job bro. keep it up!

FEM will do just fine wt d analysis

Unfortunately, I can't use FEM for the blades, no wood in d material options.

Thank you.
I'll work on the FEM.

The first shows the view of my school.
The second, however is zoomed into my site.
Red dot for where I want to mount the turbine, if you look closely, its away from the buildings and trees.
Blue dot is where I am suppose to mount, close to my department.

homerac7: Hello Sadiq,

I just saw ur post after a friend (who posted earlier on pg 1) told me abt it. Well done, keep it up.

I did works on wind turbine in my undergraduate project and I have followed the technology passionately for over 6 years. I'm quick to notice that u haven't provided some basics before you selves Into construction.

1. What's d average windspeed of d area/site u plan mounting it?

2. What's d surface roughness class?

3. What's d cut-in speed and cut-out speed of d turbine?

4. Have you done your material strength analysis for d blades?

5. What's d blade tip speed ratio?

These r some of d basic info I think you will need even before you go ahead to construct. But ASSUMING u hav done these, then I understand the mix up between electric motor and generator. Usually, AC generators are more used. DC motors have limited use. That does not mean that it won't work though. An experienced electrician can explain better.

I can see that its a roof type u plan to construct, although I don't know what height u have selected to mount it and type of buildings and vegetation around u. I will also ask dt u consider needle bearings for d yaw assembly against roller balls bearing because of losses since d load is not much.

I may not b able to say much more than ds for now based on d scanty info I hav from ur posts so far.

For d power amplification, go to oshodi under bridge where Igbo guys sell electronics parts and components, usually there r electronics technicians there who can virtually help u construct any circuitry as long as u can explain urself clearly.

Wish u well.

I have the answers to this questions in my next attachment.

homerac7: Wow...wow...wow...

Bro, I guess u hav ur cart before the horse. U normally do all those calculations before u go on to select ur materials and determine d blade dimensions. If you can't even be sure of the wind speed and quality on site u want to use it, it appears you have been guess working wc is not good when working with wind because Its d most treacherous among all the renewable energy sources. It's highly site specific, so a turbine performance in Bauchi may not b same in Abeokuta or Dutse. In fact, d first data set u need before proceeding on design are your average windspeed, humidity and temperature and surface roughness class. The first 3 u can get ESTIMATE values for your locality from NIMET or ur climatology section of Geography department if such exists. Based on d data u get ur wind quantity and quality which is what helps u to derive ur availability and cut-in speed and cut-out speed ( these after u have done ur material selection against d energy available in d wind over ur availability period). By now you can calculate ur blade tip ratio and select ur angle of attack. At ds stage, d surface area of d blade can be calculated easily and from there u can select ur length of blade. At ds point u would also have known d wind force expected against ur blades and height u can harvest best wind quality and quantity.

U were mentioning "6", I guess that's ur tip speed ration. With that I expect a not-so-broad blade but slightly long designed to run fast under low wind. That u have chose 3 blades shows u want slightly more torque at speed expense. Good selection, I say.

Back to my earlier analysis, its at point of design of d prime mover (turbine) dt u were supposed to have selected and matched it with load torque requirements. Again, the calculations would help u to determine the RPM of the designed turbine. All these parameters u can alter to suite the characteristics of d generator or final load. It's at end of these that u go on and start construction based on ur earlier design.

Now, I can only hope along with you that ur gamble works. Wind is unlike any other energy source because of its treacherously unpredictability.

Your major concern for now I guess is on generator selection. Well AC motors r more compact than their DC equivalents, what dt means to u is that it will require lesser torque. U r faced wt compromise of dt with having extra circuitry for amplification and rectification on downstream side versus higher torque whc will demand higher machine (turbine) size.

Ouch!! That's how I felt when I read this post but I can only thank you because this shaped the project in the right direction. Thank you for this post!

Charge controller!
The circuit diagram is a little different.
The not so clare one is the real thing.

More!

Here's what the new design looks like.
[size=13pt]FINAL DESIGN[/size]
[s]even if I think of a way to make it more efficient I am not going to change it[/s] I don't even have time, so its stamped as the final thing!

Front, rare and some side elevation.

PS..
Appologies for the typo in my previous post, using a mobile phone.

OK!
So, I know I said I started fabrtication some time back, I had to stop. So I have been away for a while because
I was busy working on the technical aspect of the project. My supervisor requested for it.
So I know I said I wouldn't change the design, well I ended up changing it again and again. I guess that is the down side of being a perfectionist, I can't help it but make sure I make the best out of this kind of work. However I believe that's why I almost always end up with the highest assignment score or best prestntation etc. But lose momentum a little bit when it comes to the craming/memorising aspect.
Oh well, I have been finally cleared by my supervisor.. So fabrication can start proper.
I however have made progress in the electrical part, I have my charge contoller ready, just remaing to case it, as I have mentioned in am earlier post. The pics are below.
Then I have designed my blades, going to carve it out of TEAK wood, but if its not available I think I'll use mahogany, haven't researched deeply into mahogany just teak and its the perfect choice, I just pray I get it.
So that's how far I have gone, I have one month to fabricate and test, lightning speed from here on out.

Nimshi: To the original poster:

1) At which university?
2) What's your estimate of your intelligence and ability to reason?
3) What ambition do you have for the quality/grade of your first degree?
4) What're your plans after your first degree?

Answer this questions and your good!

Over to you, AK.

Why do I have a felling this story is somewhat false. Its just too easy, and why would they just confess and implicate 2 other people and take them to their stash of weapon?
Besides I tried to google the sub-gun and couldn't find any result for that gun.
They should provide us with pics!

Why spend so much to take them to a foreign land, when you can bring the experts to nigeria and train them for a fraction of that money. They then take over and train more of their colleagues. Its simple planning! Something nigeria is seriously lacking! Just because it is money made from their land doesn't mean it should be wasted!
But wait o! Trinidad and tobago!!!! For the love of God!!
No wonder he went there, they tricked him to coming so that they will tell him the're deporting his bois!
sharp men!

They should keep winning it, no amount of gold is worth putting a kid though this vigorous training!
Haba! See the first pic! See how much pain she's in!

shymmex: What talent? If the talents in Nigeria were that good - they would have won at least one African championship..

This team is the best Nigerian basketball team EVER!!

Let's encourage them!!

You keep on encouraging them, I can't encourage this kind of thing! Why na!?

I have been saying it on nairaland for long now! Thoes guys are not nigerians! Naija no dey carry lass, why carry people who have never been to nigeria before of just claim the country because they couldn't represent another to the olympics as team nigeria?
I know native nigerians can fit mss up wella, but e no go reach this level.
Haba!! Its a shame o!!

why be cracking your brain to solve a white mans problem, when there are enough challenges in nigeria!?
who will the think of solution to nigerian problem?

Go and please others!
Leave nigerians to die!
What else do we expect after he said it on national TV "I don't give a damn"

How this guy take be nigerian?
He dosnt look it even small!!!! Colser to brazilan.

I totally agree! While at that, throw in the delete a post option as well..
This is needed, no be small.

كلورين: If we are making comparison that far back, I say sydney was nice athenes was awesome(home of olympics). But atlanta takes the ultimate cake not for anything but because of how the torch or what is it called was lite, an archer fa(bow and arrow) not cross bow!!
I don't see how that can ever be out done!

My bad! Meant barcelona 92

c-baba:
male and female ooo my broda but we dey basketball and one water sport

are you serious?? hahahaha!!!
its just a waste! imagine, when olyimpics dey happen for correct place no resonable teams to represent!
athletics unko?
all those
handball
volleyball
tennis etc! dont we have representatives?

Nigeria did not qualify right?
Talking about football..

tomakint: on the issue of more than one wife to a muslim,you know its a practise some muslims are shelving aside especially from the educated side, but Iam talking about the exponential rate of muslim converting to christianity which is in large volume, that is what I am premising my argument on

You obviously don't stay in northern nigeria. Both educated and ilitrate still marry more that one if they wish, its not being reduced because of civilization or mordern age or anything like that but because of economic circumstances.
To your conversion question.
I think you are exaggerating a bit, am sure you can't count more than 20 that reverted to your church. However, It still goes back to my first reply. Those that were never really muslims to begin with. Just bared the title muslims but never really practice. Those kind of people are mostly found in the western part of nigeria, just as thoes names you mentioned suggest. (There are obviously other reasons)

Inyamiri..
Get some exposure! Just because I am a muslim and I use arabic caligraph dosent mean am a hausa man..

vladimiros: yes I would, and when the problem starts

you would be the first to complain

When the military is going to annihilate them why would I complain.

tadysmart: Certainly Boko Haram in the house.

Shm.. Some people just have to show how... I am fasting.
How is BH related to this issue?

Go and watch cartoon joor!

I was hoping to see some high tech gadget! Hahaha!
Kai, naija!
