SD GPS Data Logger - www.ohararp.com/products
I am a small developer of embedded soultions for all types of applications. One my personal interests is with GPS positioning products. To satisfy some previous patent work I was doing I needed a device that would record large amounts of gps data (lots of memory) over a long period of time (big battery) and was compatible with mac's and pc's. Unfortunately, nothing of this sort existed and I had to create a device to do this.
This product is the culmination of implementing a number of new designs for myself. Mainly, using surface mount components, lithium ion/polymer batteries, and Sandisk SD memory cards.
Since so many electronics parts are surface mount these days I needed to use these components but was a little bit fearful in making the leap from using through hole/traditional soldered parts. Sparkfun Electronics helped my learning with their tutorials and I thought I would continue the tradition through an Instructable.
