Hi guys, I'm involved with a small racing car and it'd be really useful to record some data about it to help us with analysis of its performance. Unfortunately we're on a very tight budget (we're students) so we can't afford an expensive off the shelf job! I'm interested in putting something together myself but I'm a mech eng student so not really sure where to start! If anyone can point me in an appropriate direction to start doing some research I'd be very grateful. We'd probably be looking at something of the order of 8-10 inputs, sampling of 1 or 2hz (more for some and less for other inputs), on board storage for about half an hours worth of data and probably wouldn't need better than 8 bit sampling (more would be nice but not vital). A GPS log would be fantastic (I have one which can output on bluetooth or NMEA over serial) but I suspect that's a step too far. It would need some kind of timing to keep everything in step, and other inputs would be analogue. It would be nice to have an option of triggering outputs from the logger too but again I think that might be too much.
Any thoughts?
Cheers
Ben
