Hey,
I wanna take a project this summer and since i'm into cars, i wanted it to involve my car, meaning to use the car's battery as power supply.

At first i thought of building up a laptop charger to have my laptop charged from the car's battery, which is nice i think, but turns out to be not that simple.
So i'd love to hear your ideas :)

Thanks.

maybe a temperature sensor? or a led lighting solution (for the instrument panel for example)?

If you're into 4x4s, I've recently encountered a problem which can be solved with electronics and I've added it to my "projects to do" list. Basically I own a Land Rover Discovery and I've just fitted tyres that are significantly larger than stock. Now the speedometer is inaccurate, and it occurrs to me that I could design a project that would accept the speed sensor as an input and then output an accurate calculated speed, depending on the size of tyre - which perhaps the user could enter, allowing them to upgrade to different tyres at a later date and just enter a new size to account for it.

I'm not suggesting you design a project to solve this for me of course - I'm quite capable of doing that myself. But since you're asking for ideas, this is a real world problem you could solve :)

LOL, thanks Brian.

Actually, i just have this humble private, not this monster you described :)
I thought of building up things that you can use when going out with the guys or your girl and such.
Thats how i reached this laptop charger.

Is there anything about the car's performance you would like to monitor?

There's someone that posts in another forum I frequent, what he did was map out the solar system in the headliner of his car with leds. With the seats in the recline position he and his girl could go star gazing by simply looking up at his headliner. The leds of course would twinkle like stars for added effect.
