Bluetooth lap timer

Hey everyone, I thought I'd post my recent project. I took a trackmate racing iridium lap timer and used a bluetooth module to go wireless between it and the computer running the lap timing software.

The whole thing is powered by a 2c lipo and is in a project box, neatly contained. One wire goes out to the overhead sensor and that's it.

The real advantage will kick in when I write an android app and ditch the laptop. I'll start with a basic lap timer, then start adding features. First will be audio announcements that you can listen to over headphones or phone speaker. I also think it'd be neat to integrate the phone camera so you can take a picture of the layout, maybe include car setup info so that you know exactly what the laps were run against.
