My ethernet shield with micro SD, stopped working, to proceed I comment
all the lines that involved the log and the SD, now everthing is
working again.

My BMP085 arrived, now I'm getting the temperature and the altitude
reading from it, no mor need for the DS18B20.

Add the code to calculate the total ascent and total descent don't know
if that is working yet, will do some tests.

tested in arduino!
Some ajusts

Made some ajusts to the ascent calculations, but is not working
correctly, I'll have to make a lot of tests to make this work, and is
goi to be difficult becouse you can not simulate air pressure easey.
Some sugestion?
