Awesome video, this what I'm trying to accomplish in my car

[CaptChrisT]

Can barely understand what she is saying

I believe the kind of transmision you talked about is called manchester code? Or did I misunderstand how you said the bits are defined?

@Shakespeare1612 go for a PLX KIWI unit. Gives loads of data to you that you can record & save. It would be perfect for you.

I love you Nerdy Girllllllllllllllllllll

Congrats. This is a very neat, and practical application. It would be more safe and better looking if built an actual case around the electronics though. I drive for a living, and I keep a meticulous log of my odometer, destinations and trip times etc. Does the cars computer output odometer readings, and times? Do you know of a GPS module that you could interface with a Nerd kit?

Damn i hate progamming.

A Russian-accented nerd girl... god damn that's sexy.
