Unbelievable!

My birdhouse is almost completed, so I authorized my contractor to help register the house officially to obtain the house no. With the house no. I then can apply for electricity,water and Internet. It is unbelievable that the no. I obtained is 49/1! My current house no. is 49/94, my rented building no. is also 49, and now my bird house no. is also 49/1. This must be my lucky number. Of course I didn't pull any string to get this number. I am not that superstitious, a little may be, but isn't this really something?

One Fine Day

External sounds were turned on Saturday Dec18th, but there are still many unfinished works inside and outside the house. Birds came to visit the house almost every day but wouldn't go inside due to workers, noise, smell,etc.

Until Saturday Dec25th, all works inside the house were done. Thus Sunday Dec 26th was a quiet day.
Birds became brave and sneaked into the house.
FYI, I haven't turned on the internal sound yet. No bird shit, no aroma at this moment either.

Sorry for the poor quality video.The below videos were taken by an iPhone from a recorded video from CCTV on a computer.
I just don't know how to put the recorded file with .DAV extension into Youtube, anyone know how, please advise.


Birds flied above the open roof entrance hole around 5.06 pm.


Into the Roving room.


Further into the Nesting room. Most of them flied in and flied out very fast as they were still not quite sure of what's inside, just my guess.
If you looked carefully, there's a sliding door at the nesting room entrance. This I can regulate the opening width to control the light or darkness inside. In the future I can also put a motor and timer to regulate the opening and closing of this door, if needed.

Nothing much to do.

Since the bird house is almost completed, nothing much to do.

As an Asian, I always wanted to watch Asian movies, but if without English subtitle, it's not possible to understand the language. Recently I found a website dedicated to Asian movies with English subtitle.

Ahhh, my dream came true. There are soooooo many Asian movies, be it Korean, Japanese, Hong Kong, MainlandChina, Taiwanese, Philippines or Thai. You can watch the movie on line or down load it first. It's free and no advertising!

If you like it, send me one of your good good sound, ok? :)

New Idea About Ladder

Since my BH is a simple 6 x 20 meter.
My hubby came up with an idea of a device to replace ladder.
It's only an inception of an idea, not materialize yet.

So I want to share it here.
He said we can put a rail similar to those use for railway on both sides of our 6 meter wall at around 1.50 meter height.
Then we put a piece of plank reinforce carefully so it will not sack at the middle at such a long span of 6 meter ( actually it was only 5.7 meter due to double walls), with wheels on both sides. The width of this plank can be around 60-80 centimeter. We still have to find a way to be able to manipulate it, ie, move and stop where we want.
Thus this device need not to touch the BH's floor which is full of bird's shit.
The idea was adapt from an industrial traveling crane.

What do you guys think of our day dreaming?

A Good External and Internal Sounds

Now since my BH 's sounds are on.
A good external and internal sounds will be very crucial at the moment apart from other factors that were already decided, ie, location, design, sound equipments, speaker arrangement and system (temperature, humidity and ventilation) controlled equipments.
It's not easy to choose the right ones from what's available in the markets right now.
Can any one here give a sincere recommendation on what are the good external and internal sounds?
Please, please, please.

A strong ladder

My hubby fell not once but twice from an aluminium ladder on the same day while working within the bird house last week.
Luckily he didn't get hurt that much, just some wounds on his hands.

So yesterday when we went shopping at HomePro, we found a good strong ladder.
It's not for sale, it's for their own use, so we asked their permission to take the photo.
Just in case we want to fabricate one later.

This is a taller one more than 2 meter height.






This is a shorter one.



The disadvantage of this strong ladder is it can not be moved to another floor.
I guess we need one for each floor.

Coincidentally, another blogger, Charles are also working on this similar type ladder, but he will add a remote control into it too. How cool! http://my-diy-center.blogspot.com/2010/12/bird-nests-harvesting-trolley.html

The Latest Look

Ain't it look good with little details added here and there?
People in the area thought I am building a resort. Yeah it's a resort, a resort for birds.:)

Opening day Dec18th, 2010

Although every things haven't been finished, still a lot to do here and there inside and outside the building.
I insisted to open our bird house yesterday despite it's not a good practice to start operating on an unfinished house.

The reason behind is a bit superstitious.
Me, my hubby and my partner, three of us were all born on Tiger year.
So yesterday is a Tiger day and also in a Tiger year, I just hope it should be good for the success of us, the three tigers, cheers!

Wish me good luck.

Micro of the unfinished house 2.

Micro Conditions at my BH Dec11-12,2010

House is almost finished, but there are still here and there to be completed. Doors and ventilation 90 degree angle fittings are not put on yet. Outer wall on the North side isn't finished, thus North side has only a single wall at the moment. But there seemed to be not much effect because during this season, the sun moves from East to West on the South side.

Still working on the outer wall of North side and just start working on the metal sheet roof.
Quiz: How many workers in this picture?


Data were taken by taking photo from the thermo-hygrometer when ever I remembered, so some data were missing.

One thing looked good is that the temperature peaked around 4 pm and then started to decline. This is because the West side of this building has a very effective double wall which are 2 meter apart. So the hot ray could not get inside the building on the West side as easy as the other sides where double walls are only 20 cm. apart.

I've seen data from other's house of which West wall was not fully protected and poor ventilation , the temperature kept climbing up until 8 pm!

A New Toy!

This is a toy for children bicycle, cheap cheap one.
I think it is applicable to be used in our bird house.
Clip it to a piece of long pole, the angle is adjustable.
The mirror itself is also adjustable.

When done, no need to go up the ladder to see whether there is egg or young baby in the nest.

Water Level is getting higher!

Rain kept pouring, water level is still increasing, workers couldn't stand to work by standing on knee high water.
So no one is working on the exterior wall.
Luckily, inside they still can work on planks finishing.






I was told that yesterday thousands of swiftlets are playing around the bird house due to the flood water.
You can see how much I really wish I can put this house into operation soonest.

Flood Again?

Sigh! Flood came back again.





Proudly presented, my friend's BH after only 6 months of operation. We must have done somethings right.

From his blog: http://swiftletsourceofinformation.blogspot.com/2010/12/6.html

Have you ever checked the quality of your sound?

I have exchanged many sounds with others, I never checked their quality. Because my BH isn't finished, I haven't tried on these sounds yet.
One day when I re-exchanged the sound I got with another guy. He told me that my sound was not good.
I felt so embarrassed, so I checked all my sounds and found that most of them are bad quality, with interruption, back ground noises and clipping all over.

What is clipping and what caused clipping? "Search Google for Clipping Sound"

Effect of Clipping sound:
Clipping sound will give distortion noise and can damage your speaker.
So I have to find a way to fix all these clippings, cannot cure them all but at least to a certain extent.

Don't ask me how to do it, just "search Google", as simple as that.

The Absorption of Sound vs. Relative Humidity.

I was told that the mist produced by mist maker will adversely effect the echolocation of swiftlet.
To my suspicion, I search google and found the below article of which I still not quite understand.
So anyone in here can lighten me up will be highly appreciated.


Effects of Humidity on Sound

Contrary to what most people believe, there
is more sound attenuation in dry air than in damp air.
The effect is a complex one, and it is shown in
Figure 1-11. Note that the effect is significant only
at frequencies above 2 kHz. This means that high
frequencies will be attenuated more with distance
than low frequencies will be, and that the attenuation
will be greatest when the relative humidity is 20
percent or less.



Credit to Sound System Design Reference Manual by JBL

Today,Dec 2nd, I was kindly advised by my friend who is a physicist that the above article explained that
lower Relative humidity has more effect to high frequency sound than higher humidity.
But he also remarked that mist and relative humidity cannot be considered as same thing.
As mist is still a fine droplet of water,but for relative humidity, water is evaporated as gaseous stage and is almost homogeneous to air.

I guess a good physicist will be a good BH owner as sound , ventilation , temperature , humidity are mainly physic.
