December 2010

Book that I bought in December 2010.

It is an Encyclopedia for Ocean.

Saccharine tear jerker...

That was one comments line for movie critics (誰も知らない , 柳楽優弥)

seen on a western movie review website.

Actually these drinks really contain no sugar, no fruit juice,

only Saccharine + Acesulfam + flavouring.

But the illustration is good...

Actually...have you ever tried to drop a saccharine tablet on a hot cooking plate?

Like the smell? Think twice if you want to drink this every day.

But this is no longer much important for me.

For this reason, Teacup blog is not maintained currently.

Two SEGA systems were disposed a while ago...

And I don't write PC software anymore for maybe 2 years.

I don't care!

However I do research for electronic circuits.

it is more interesting for me than computer software.

SMPS switching power supply, based on TL494 chip!

I have 500W toroid transformer here now.

Output 105 volts DC!! Highly dangerous.

I worked for last 2 months nearly every days to build circuits.

For instance serial LED display firmware was ported to C language!

16f54 microcontroller!!

There you can see even the source code for master microcontroller.

But display firmware is not published to internet at this time.

3-wire interface. And cheap construction.

These displays mean a big advance for many of my circuits.

A lot of time saving and cost saving.

And completely my own work.

柳楽優弥 - Nobody Knows - 誰も知らない

I was not too happy with the original DVD cover.

It was edited. This time, CRT light from the background.

(CRT= old technology coomputer monitor)

You look at all these people doing black&white photography,

and ask, why they are doing it? What's the purpose of black&white photography?

Actually, I don't have any pictures on my wall.

It's only distraction and suffering.

LED displays that are driven directly without using any extra parts.

Some engineers think, the displays, or the chips would burn out.

It's pretty much nonsense. They are used at 3 volts.

If you look on the internet, you can actually see many circuits,

having extra parts that are not needed at all.

And Serious Sam 2...

With many crazy missions.

Nobody Knows Special Edition 柳楽優弥

柳楽優弥 - Nobody Knows - 誰も知らない

I have copied one DVD chapter to my hard drive.

Yesterday I tried for the first time with this project!

The idea is to cut the movie totally differently.

For instance let's think of Mean Creek.

There is also some troubled youth.

But there is not so much details as in Kore-Eda's work.

It is not a totally famous title but made it into the cinema.

There is more emphasis on one fierce youths character, than on the corrupt system.

Oh yes it's true school is bad, school is not the place where you will learn anything useful.

And SEGA is corrupt much more than Nintendo, as we know it.

The problem with Kore-Eda is he paints everything as corrupt.

It can be true but not everyone likes these kind of movies.

Or is it better to use a cartoon plot like Tekkonkinkreet?

Surreal worlds can endure much higher degree of corruption.

I don't really know how to cut the movie, or where to cut it,

or what should be the right storyboard.

I think, one day, I could simply do it, and it would be right.

The plot would be shining in a totally different light.

Some scenes would be absent or cut or moved in time.

And some additional scenes could be interesting too.

But that is not easily possible you can't just turn back the time.

Or you could create a different cut of the plot that no longer so much

relies on Yagira Yuya. It's not unsual for movies to shift back and forth over some years!

But what would be the reason and can it make sense?

Like japanese manga, if it is done right, the same thing can be done with movies like Nobody Knows,

you simply remove the linear timeline, and the strong correlation between the scenes.

I did not say I am really a big enthusiast about japanese manga.

But it's true, different than western cartoon.

There is sometimes not even a weak correlation between scenes.

So, it is not that I am playing around with the scenes all day, or that I am watching this movie

over and over again. I don't watch it at all actually. It has some fascination to me, compare it

to a new video game that you bought when you were young. It does not last forever.

I have disposed all my SEGA stuff recently, as SEGA is no longer supporting the 1980s/1990s platform

in any kind of way. Well back then $50 to $70 was a big lot of money for youths, like

in todays money, maybe $300. It was not possible to buy new games very often.

And we must not forget about the Karaoke and the Sushi which was a present.

As for Beyblade 2, "Tyson, stop the crazy singing!"

Nobody Knows lined up too many details, and for some people, it was too long to watch it more than once.

For instance Shining Boy and little Randy I would not want to rearrange it- it's OK like it is.

Isn't it some kind of tragedy without existing imperfection, there is much less potential for additional creativity?

But you don't do the school system a favour when you say it actually creates very creative and talented people, those who drop out of the school system, and make it otherwise. You could say the school system is geared to produce these dropout genius type characters, but I would not be too sure about that.

There is also more than one chapter on the DVD. 1 Gigabyte is converted to about 450 Megabyte, and takes about a minute to load. Editing can be done instantly, it's easy to cut together scenes. But thinking too much about it is not helping it. I don't think I want to do this now, but, I started.

binary LED matrix clock

now approaching completion of the project.

Also construction of a large 32x24 LEDs matrix has been started.

It is based on 16f716 microcontroller.

• I2C realtime clock
• 1.2 volts power supply
• 8x2 LCD used to show day of the week
• charge pump to use LCD at low voltage, 2.6 volts
• 3x4 LEDs matrix to show seconds, minutes, and hours

Hitech C is used for the control program.

The microcontroller clock frequency is 500 KHz.

According to Dungeon Siege, the weather as we know it is controlled by

"The Great Clock". So if you build a really advanced clock,

you can control the weather too.

I do not know if it too works using these WW1 era pocket watches

which have radioactive paint on their hands.

Could not it be true that having round clocks and "hands" for the

seconds, minutes, and hours is just simply wrong?

in the 16th century, it was the only technology available.
