Good, glad you're thinking about it. There's a few good articles on the 
net, one written by a university team who tried to do this kind of thing 
using accelerometers. They eventually gave up and incorporated GPS and 
then got very good results. Sample rate seems to matter a lot when 
trying to derive speed info from acceleration, but you've already got a 
direct measure of speed so you might be able to work something out. Try 
here:

That's reassuring, assuming that the manufacturer keeps backward 
compatibility.

This is the kind of thing I'm interested in. Temporary storage is just 
useful, and should be simple. I've thought about a real-time display and 
just about ruled it out, for the same reason that you have alarms - you 
can't concentrate on the display when driving. I do however have some 
other potentially cool things to do in real-time, and that's why I was 
interested in the real-time serial feed.

Good ;-)

Please put me on the seriously interested list, and a potential beta 
candidate if you can use one in the UK. I do about 1,000 miles / month, 
regardless of the time of year or weather. I might even throw in a 
winter track day or two.
