I am looking for a way to log NMEA-0183 data, without using a PC, from my sailboat onto a memory card for use with sailing performance software. I am looking for a solution that runs whenever it gets +12v, without me even thinking about it.
My current method of placing a memory card in a chartplotter is proving useless ... as I continously forget to start the diagnostic capture feature on my charplotter in the midst of quick preperations to get underway racing each wednesday night.
Dan, Brookhouse has a logger they might be able to modify for the data you want to log:

But I'd guess that a netbook with Franson GPSGate on it might cost about the same, and have many other interesting possibilities. Still, you'd have to remember to turn it on ;-)
