[PSUBS-MAILIST] DSV Aquatic update

[Alan via Personal_Submersibles]

Great work Jon, must have taken quite a bit of time.
I don't think you have too many sensor inputs; I worked out that I 
needed 60+ to be  in line with GL requirements.
I looked at the display video & it was quite easy to follow.
Did you model that on an existing submarine display?

Although not really necessary, layering various "breakout boards" onto PCB foundations that use electrical traces to connect various parts will definitely cut down on the mish-mash of wiring that would otherwise be required.  I have settled on a configuration providing 16 each of analog, serial, and I2C sensors.  This is way more than I ever anticipate needing however it does offer plenty of room for expansion and doesn't cost much more than limiting to 4 or 8 sensors...so why not go for it.

In my prototype I was using an Arduino for sensor data collection and a Raspberry PI for graphic display however I am now thinking about using a second Raspberry PI for data collection to take advantage of the huge difference in processing power available with it compared to the Arduino.
