What is MATILDA? Did you refer to e.g. the ABS ergonomics guide or other references when designing your alarms?Sean

Hi Alec,

Pitch and roll on a K-sub are negligible but the sensors are "free", 
part of the electronic compass, so I added them to the display.  The 
pitch might come in handy to help with longitudinal balancing.  
Roll...well if I ever get stuck on a sloped bottom I can radio to the 
rescue divers "you can't miss me, I'm the sub leaning port at a 25 
degree angle".

I think Cliff pointed us to a depth sounder/speed combination sensor 
that he is using which would work well for altitude over bottom.  It 
would be easy to add that into the software, just a matter of getting a 
unit and testing it.

One thing that the demo fails at is my implementation of MATILDA, audio 
warnings corresponding to the yellow/red alerts that are displayed for 
various sensors.  A yellow alert sounds a gentle "ding-dong" sound 
followed by the sensor name spoken by a computerized voice (!
 female
of 
course) and a red alarm sounds a high pitch smoke-alarm sound followed 
by the sensor name spoken by MATILDA.  I was too lazy to set things up 
to record the audio for this demo but will do that at a later date and 
of course will have it available for the convention in July.

 That's gorgeous! I'm curious though about the pitch and roll, it would 
 seem you wrote it for a "flyer" sub. One data point that would be a 
 great addition would be altitude over bottom. Not sure if you've 
 figured a sensor for that, but if there is one it would be great to 
 display right next to and analogous to depth.

 Best,

 Alec
