I had an old fashioned Hot Lap timer in my car this past weekend and had problems with it. Actually other people had the same inconsistencies. I was looking at a Droid App by Trackmaster. Does video and lap times, speed.

how are these things getting a signal from a base station?

They must pick up a signal when passing some sort or marker, right?

Yeah, a GPS point that the user can define. You can do it on the phone, or on a computer and send it to the phone. Basically all you need is one GPS point (the starting line), or you can put in multiple points for sector/split times. The GPS on the phone knows when it passes that point, and records that information in the form of laptimes/split times.

Trackmaster does all sorts of other stuff. You can do a "LiveView" which lets you track the car on the course via a laptop or second phone. It also measures top speed, G-forces (roughly) and several other parameters within the phone's capabilities. The phone will actually call out split times and lap times if you select that option too.

I'm going karting this weekend for my bachelor party - I'll try to post my datalog on here so you can check it out.
