I didn’t change anything with the electronic parts, but did get a new case for the data logger. I tried long and hard but could not find a way to fit the GPS antenna inside the case. The Molex connector goes to the status LED and switch shown earlier. The switch I changed from being a

Now on REV: C finally no flying mod wires on my accelerometer / gyro board. Only the accelerometer is populated as I left off the RC filter for gyroscope, so the board is only half working. With the micro, xbee, and accelerometer it draws 57.4ma. Since the xbee claims to take 50mA, 7.4mA for micro

I’m now back to the same functionality I had on the version I built on proto boards though now much smaller. I added a run/stop switch on the side. Each transition from stop to run will result in a new file being started. Two lights on the top, the green one is lit when the

After having the boards for at least a month I finally built one up. This board dosn’t really do much new it is basically my GPS logging hardware v3.1 built onto one board. Since I was building my own boards I opted to use a atmega1284p since I was having issues running out of sram before

Bit of a delay moving on this project, mainly because an error in the board I was building to mount the SUP500f GPS to had an error which fried it. Since sparkfun stopped selling SUP500f I had to find another GPS module. I ended up not going with the recommended replacement mainly due to the

Well this is not as much a new version but moving the components off the breadboard. It has always been my intension to use the small prototyping area on the microSD shield for my first revision of the hardware. All in all it has worked out well, the shield is for the most part the

Due to some memory and timing issues with my attempt to do everything on a single processor I have split the tasks into two processors. There is one processor dedicated to parsing the info from the GPS as well as any other sensors which will be added later. The other processor takes the input from

So my next step in my GPS logger project will be to pull the components off the breadboard and build a small prototype to gather some more real world data without needing to be so careful with it. So I figured I would take some time to describe the general layout of the current board.
