@wenchintraining Hey Em, I think I need you along to flip the raft again... Then you can know first hand! I should have this all loaded up on my next rafting trip so I will keep you posted!
Very cool! I like the map display. Mbed processor? I have one but don't like the closed libraries and online environment (although it looks like there are ways around that). I am playing with an STM32 Discovery board (not quite as streamlined in terms of dragging and dropping an object file onto a mounted USB device), and it is nice because ST provides source libraries for all the onboard peripherals. Anyway, the microSD and BT are impressive - the phone display is cool!
@kc8kfi Yeh, its the mbed. It is really fast to develop on. It took me about 3 hours to get a Fat file system, SD card, GPS, analog inputs and Bluetooth all working together and producing meaningful results. On anything else that would have taken a lot longer. I try to use GCC for all my commercial projects, but I just don't have enough time to mess with it for fun projects. My biggest complaint about mbed is no debugging. Even if you have a real JTAG programmer you cant make breakpoints.
@yardleydobon It actually already does! I log the X and Z axis, +/-15g each. That is all tied in with the GPS log and recorded once every second. I want to make it record more often when it senses some fast than normal activity like going over a waterfall. I think I will have it sense if either axis has changed more than 1/4 of a g in the last 100ms and change the logging rate to 50~100ms.
Nice job, congrats on the iPad!

Ha ha, cool! You should log when you are in free fall too.
