Point me in the right direction

Hey all,

Been out of programming now for about 5 years. As once learned, it is quickly forgotten. I have a project that I need to get done, a real simple one and I can find all the parts here at SparkFun.

Looking at using the Logomatic v2 Serial SD Datalogger to take the input from two devices. GPS sensor and Digital Compass Sensor.

I need a trigger switch on when to record the data and the rest is in output file so that it can be transferred over to a Windows/Apple/Linux box for further processing.

I am open to all suggestions and tutorials that anyone can throw at me. I am trying to do this myself without having to hire a programmer or electrician to help me complete it. In the event that anyone does know of a pro to help me in the event that I run out of time, list them here also.

Thanks in advance.

Frank
