Hallo
Here are few snapshots of my system running with Linux.
The software which drives everything inside is home made including the interface.
The system first started in summer 2003 with a Playstation's LCD screen and an old pentium overclocked 133 Mhz.
It was hard to make it work but finnaly it worked, the first results were very poor with black and white picture then came the color
but introducing another stability difficulty.
anyway those difficulties have been solved to give this result
After time spent with experiiments at home it was time to put
all the stuff in the car.
I was happy with my thing in car, having music with a multi format able player then i had the idea to be able to stop my car.
There are not so much options, first started thinking about recognizing
dtmf sequences sent to a handy but unfortunately my handy was unable to recognize those sequences through it's port.
So no more options but using then sms.
Now simply sending a sms is ok but reading it's content is something else, more than that it's even harder to recognize the caller ID (i mean for a machine).
That's why i started again experiments at home till it worked fine.
here's the screenshot of what happens when the machine receives the sms.
The picture is too big you can access to it at http://81.56.210.152/capturesms.jpg
In the same time i made something to wear the metal bezel.
Ok don't laugh at this time i was with no more job, hard times so difficult to have a beautiful screen.
Now it was time to put some more software inside.
I wanted a voice synthesis, then i used the Carnegie Melon University
festival project.
I wanted also to have a gps so i started using GPSdrive but i had to let it because that there's no cartography library and the displayed cards are static.
I wanted too that the system was automated so i don't have to bother
with stupid buttons everywhere.
And finally here's the result with the multimedia player XMMS which was good for the task i wanted at this time.
Was it enough ?
No it wasn't as those little systems are so addictive.
More i had more i wanted. Why not now let the computer make some
monitoring ?
Yes good idea, unfortunately the Porsche 944 before 1988 was with no OBD nor pre-OBD so what now ?
I refused to accept the defeat and built my own system to gather informations form the car.
10 channels with a refresh speed of 5000 measures per second.
We are far best from OBD aren't we
The first attempt was to get the air/fuel rate with two ways of displaying.
One with a simple display and another with fine curves displaying what was hapening to the lambda sensor in real time
And today ?
Today i changed every little part but this is for the next part...with still home made interface, with a home made kernel using another hadware
and new features included...
