I dunno the boot time now (still doing emerge -eq world, forgot to add some cflags),
but the bottleneck is the init system now, the time between the bootloader and the start
of init is negligible.

Using gentoo-sources-2.6.30-r8, will add some stuff to work with ICC.
Benefits of using ICC over GCC for an Intel processor are obvious I think (+10%-40% speed)

I'm planning to use a very basic audio software with mp3 and flac support.

I'm using gentoo and custom build apps because I don't like apps that just work

I want challange, and small benefits from huge efforts

That's why I'm messing with an 8-year old car instead of buying a new one.

I have no A/C in the car, summers are hot here, and passive cooling is more reliable,
and also, saves some power.

EDIT: switched to 32-bit from 64-bit, to keep multilib issues out (I need 32-bit because of Igo8)
Anyway, everything has better support on 32-bit, for example, compiling kernel with ICC is very
easy now, thaks to guys from LinuxDNA.

Layer 8 issue

Successfully migrated to gcc-4.4.2 from 4.3.4. (emerge -eq world)
Had some minor problems (user error), wasted two days because of
typos in use flags, cflags, etc. (I started the install at 7:30 and then go to work,
emerge failed at 7:32)

Installed icc-11.1.056 too, I'll play with compatible packages & kernel in the afternoon.
Will post make.conf and /etc/portage/package.* (hopefully).
Need to emerge life, too

Bad news

Got a little accident, right mirror gone :S
No problem, always wanted electric mirrors, no fancy M3 of that kind of stuff,
I'll go with a factory one, I makes the car unique, as everyone using M3 mirrors
on their corsa here

Audio and Interior

Weekend coming, so finally, I can work on the audio and the interior (a bit sick of software now)

Here's the plan:

-complete sound deadening, approx 100 sq ft (~9 sq m), my final choice is Fatmat Megamat
-JBL C608GTI components to the front
-JBL GTO 75.2 Amp, budget spent on the components and deadening

-custom speaker mounts (Thanks to Coops from opelforum)
-custom door cards (to fit the new speakers and the electric window & mirror switch)
-new wiring to the door (added electric mirrors, electric windows, new speaker cable)

As you can see, no subwoofer and only 2 channel amp. I'll connect a woofer amp to
the aux out of the GTO 75.2 later, and will add a decent woofer (or three), but only
when I'm finished with the more important thingies. (again, almost the whole budget
was spent on the deadening and on the components)

I'll start with removing the metal trunk floor (standard in corsa van), and replacing the
metal grille with something, temporary. I must separate the two seats from the trunk with,
as she's a 'truck', at least in her papers

It will take my whole weekend, as the trunk floor fitted with headless screws (their heads
designed to broke off when they screw them in, so it's impossible to remove them at home)

Weekend - Day 1 - Weight reduction

So, I removed the metal trunk floor, the grille and some plastic side panels from the back.
Result: -45-50 kgs!!! Maybe I'll need new springs, as the back of the car is higher by an inch
after the weight reduction. Noticeable difference in acceleration.

Pictures:

Removed some plastic, to reach some screws

I needed a drill and a flex grinder to remove the screws

Can you see the dust and the metal chip?

Finished, now time to clean

Hi, i got the capacitive touch screen after checking you thread. It a very cool project you got going.

can you suggest where to get the 3M EXII-7010UC USB connector cable from? I am modding a dell mini 9 to be a touch screen tablet with gps and accelerometer.

Thanks

**tripzero** · 11-16-2009, 02:06 PM

What driver are you using with the capacitive touch? Where did you get it?

**gowthamj** · 11-16-2009, 02:16 PM

i got it from ebay, from the link that simplex posted on his 1st or 2nd post. I dont have a cable to connect the touch screen controller to USB. Until then i donno what driver to use.

**simplex** · 11-17-2009, 05:18 AM

Well, about the cable, I made one from an old USB cable (careful with polarity, you
can burn the panel or even the mainboard)

Linux has support for Cleartek/Microtouch touchscreens, as far as I remember,
it's in the kernel config somewhere in the Input devices or HID devices or USB area.
Well, atleast in gentoo-sources.
