I am thinking about building a displayer-logger of velocity-pitch-roll data on my sailing dinghy (the boat looks like this http://www.thmartinez.com/data_folio/da ... 01_img.jpg). I would also like the option to add some more sensors in the future (2-3).
I've been reading about arduino, sensors, this last week, and everything looks great and challenging...
The display:--------------------(box 1, linked to box 2 by cable ~50cm)
Display needs to operate in bright sunlight, so I am looking for light background 7-segment. Not sure where to get those.
Idea would be to get 3 4-digit 7-segments displays to show velocity-picth and roll.
I'd like to have something like what is show in figure 1 (see below); big digits are 1.2'' and small ones are 0.6''.
What I found are dark background 0.6'' digits, where can I find light background 1.2'' digits?
The logger:---------------------(box2)
So this should get the numbers, and log the data to and sd card (or similar).
So for this, I ll need
1) gps: LS20031 http://www.sparkfun.com/commerce/produc ... ts_id=8975
2) sd logger: loads of differents things here, and I am struggling a bit; would OpenLog work fine ok? (http://www.sparkfun.com/commerce/produc ... ts_id=9530)
3) dof sensor: or IMU+AHRS; I am thinking about the ArduIMU+ V2 (https://store.diydrones.com/ProductDeta ... ArduIMU-20) or would the IMU 9DoF - Razor (http://www.sparkfun.com/commerce/produc ... ts_id=9623) be better?
4) arduino board.
Thanks for reading,
Nico.
