Computer Exhaust...

Summer is here.
It is getting hot.
It doesn't help that my computer is always on in my room.
My room can get up to 28C in the afternoon.

There are two problems.
First is that the blinds are blocking the only window in my room.
Second is that my computer blows out air that is about exactly 10C above room temperature.

I have two solutions.
First is to move the base of the blinds down.
Second is to make ducting to direct the hot exhaust air from the computer.


I first move the blinds down.

Drilled the holes for the mounting bracket

As usual, something went wrong.

Blinds moved down. Also notice my window screen is now held up by Duct tape.

Then I make the exhaust.

This is used as a mounting bracket for the fan.
It is from an old Antec PSU I had that had trouble turning on, and exploded while testing it with a PSU tester.

A Coolermaster 120mm 1200rpm fan I have laying around.

4" duct hose.

Cardboard box that I will using to cut an adaptor out of.

Measure once, cut twice.

Held on by wood screws.

At that point, if I were to rest the exhaust fan on the blinds, it will not clear the window opening by about 1".
So I need to rise it up by 1".

I just happen to have a piece of tube left over from my other projects.
It just happened to be the right length too.

Double sided taped to a slightly wider piece of cardboard

so that the tube can sit flat on the blind base.

And then the exhaust fan stuck on top, also with double sided tape.

Duct hose zip tied to the adaptor.

and adaptor put back on the fan.

The fan is currently held on by duct tape.

duct routing

points right at the main exhaust fan from the radiator.

Hopfully now my room will not get as hot.

650cc injectors

Last Sunday, I installed the 650cc injectors.

Overall, they were easy to do.
Undo the two nuts, remove fuel rail, remove the two studs for longer bolts, and take the injectors out.
I didn't releave fuel pressure properly, so when I removed the first injector clip, the injector shot out, and spilled fuel everywhere.
The part that took the most time was soldering the new injector clips.


In a true redneck style, I was using a lighter to heat strink the tubes after I solder the injector clips on. With the spilled fuel and open fuel rail about one feet away.
(Of course, the spilled fuel had already evaporated, and there were no more fuel in the fuel rail.)
Then I wrapped the wires in electrocal tape to keep them organized inside the holder.


The old injectors came out without problem, and the new injectors went in without problem either.
The oiled O-rings were really slippy.

Since the new injectors were longer, and new studs are too expensive, I used bolts instead.
To space out the fuel rail, I used a stack of washers.


Overall, this is one of the simplest DIY I have done on the car.

Baffled oil pan.

There was a DIY meet at Modern Image in Abbotsfort 2 weeks ago.
Of all the things to DIY, I chose to install the baffled oil pan there.

J's Racing baffled oil pan

Due to time limitation, I didn't take much photos.

When taking off the oil pan, I ran in to a few problems.

First, the engine mount was in the way.
I had to take off the mount to remove the oil pan.

Engine mount in the way

What I found out after removing the oil pan was that there were quite a bit of old oil left in the pan after draining it.

New oil pan on the left, old pan on the right. Notice the oil return nipple on the new pan. :)

A quick look at the oil pump and the surrounding area




The next problem is the two tubes that holds the oil pan in place before the bolts are bolted on. Took me a while to find out why the oil pan was not going in.

That tube on the top right corner

In the end, the install took longer than expected.
I don't think it is leaking oil, but I have a feeling that it has a slow leak...

Those damn flying insects

I have been removing lots of flying insects from my bedroom for the past few months.
They can be as big as a Dollar coin, or smaller than a sesame seed.

I don't know which way they used to get into my room.
It is either my bedroom window, or the door. I think the window is more likely.


Either way, they annoy me a lot and I have had enough.
I am making a bug screen to block them out.

After school today, I went to a local Home Depot store, and bought the smallest roll of screen they have.
It happened to be 36" x 40".
My bedroom window is 25" x 25", so I had to cut it down in size.
I left some just-in-case-I-mess-up margin, and cut it into a 26"x26" square.


Due to time constraint, I did not make a proper window screen yet.
Instead, I used the cousin of the thing that fixes everything (Duct tape): Green painter's tape.


A few pieces of tape, and the screen is nicely stuck on the window.


I added a few more pieces at the bottom because of the window lock bar bump thing that sticks up.
This will have to hold until I have time to make a proper bug screen.
If not, I will upgrade to Duct tape because it fixes everything.

My observations and thoughts on Hatsune Miku: Project Diva

I was trying out the Hatsune Miku Project Diva for PSP.



Read Clear Tranquil's blog post to see what it is about and his thoughts, then continue reading to see my observations thoughts on the game after trying it for a few hours.

Title screen:
The Miku in there is in the costume chosen by the player.



Saving/loading screen:


It doesn't have its own saving/loading screen. Instead, it uses the standard Sony screens.

Navigating around:
Are you sure?



Considering how slow the game loads, this can be a good thing.


Game play:
Depending on the song, it is either a real-time rendered video, or a slideshow.




For the real-time rendered videos, Miku will be in the chosen costume.

Original outfit

Heart Hunter costume

Yowane Haku costume

On some songs, the screen is really confusing.
Which button is next? (proper order under the screenshot)

3214

4123

654123

654123

Another annoyance is the button chime.
Default is ON. There is no option to change the default to OFF.
You will have to change it every time.

Lower left corner: Button sound ON

Lower left corner: Button sound OFF

The way the game responds to button presses is kind of strange.
If a button was pressed early, it will kill the combo.
On the other hand, if the button was pressed late by the same amount of time, the combo will keep going.

The game lags a little on the real-time rendered songs.
Hopefully, the problem will be gone when I get the UMD, and it is just a problem with my memory stick adaptor and the ISO loader.
On that note, I am running the ISO on a PSP-3000 with 5.03 GEN-A firmware running under ChickHEN R2, using the Sony ISO driver.
Screenshots were all recorded with CamStudio, streamed to the computer using Remote Joy.
