Boost Meter

So yeah, i got a small original turbine rotating in my engine compartment. Last time i checked it's called a turbo.

Anyway, i stumbled upon a cool dude that had made this to his Impreza, so i thought i wanted to give it a try.
As i got an older car, i do not have any fancy places to install the display, so i got a lamphousing, removed the glass, replaced with acrylic and sanded it giving it the frosted look.
I even added a "gyro" and a barometer.
Components used: Barebone Arduino, perfboard mania :P ADXL345 BMP180 MPX4250
Cables and LED's, some more perfboard!

Hah, already gotten tired of the layout of the meter, so now i am going to remove the clock in the dashboard and replace that with the boostmeter instead.
Removing the gyro as i have noticed it is only a "fun" thing to have, nothing necessary at all! New layout would be the boostmeter in center and perhaps some leds indicating rpm and a shiftlight.
RPM indication would follow the curve of the former clock on the top left between 9 to 2 o clock. Major problem is what i could/would have between 9 and 4 o clock on the bottom?

Another Update
This car was totaled, another car crashed into mine.
But at least i saved the boost meter, to be used in a future new project.
Too bad my new car is not turbocharged :/

First Iteration:

Second Iteration:

Third one will come evetually........

Yeah, uhm, got a newer car and was thinking about upgrading the boost meter once more and after that. Publish the schematics and code.
But it will now be reading the can bus for the boost. For this i need more time XD
