I’m so very sleepy today but I should post about this before a nap…After many many many revisons, my GPS data-logging shield is done! Ive spent the last few weeks taking lots of data, so I think its pretty solid. The design supports 4 different (popular) modules, and writes data to an SD card as a plain text file. For geo-sensor tracking, I wrote a sketch that will log 3 analog sensor values along with the location, date and time. Many people have asked me over the years about DIY GPS loggers so hopefully they will be happy now.
Phew…I think I’m going to take a break from designing new Arduino shields for a bit: I’m pretty happy with the 5 I’ve got and there are many other neat projects clamoring for attention.
