[PSUBS-MAILIST] Matilda - you'll never dive alone

[Joe Perkel]

Jon,

Oh no, now you've done it, now that's way too cool I have to have it!! Maybe even HAL's voice, (Na, too creepy!)

I'm not going to delve into that now but, somewhere down the road rest assured I'm looking into that further. Along the same lines are video overlays for depth and heading, all stuff to play with later, but definitely on my to do list!

I envision incorporating various high tech toys overlying the basic bare bones critical systems, all for the pure fun of it. The pilot in me will determine a minimum equipment list and red tag yellow tag system, but you've just got to have fun with this too!

Thought this might interest some of you.  With little effort I can 
incorporate some basic audible alarms into my environment monitoring 
project to notify me of off-scale sensor conditions.  At first I 
considered just sounding a buzzer and flashing a light next to the 
sensor that was off scale.  For just a few dollars more I can include 
mp3 playback of synthesized voice warnings for a particular off-scale 
operating condition, ie. low oxygen, high carbon dioxide. I edited 
together some aircraft warning sounds along with synthesized voice from 
an online text-to-speech convertor to create a small library of voice 
warnings I call "Matilda".  MP3 recordings attached.  It requires a bit 
more hardware but from a software perspective the program is only a few 
lines longer than implementing a basic piezo buzzer alarm.

Pre-dive checklist will include testing alarms to ensure they are 
working correctly and an override button will allow stopping the alarm 
during operations so you don't have to listen "Matilda" all the way to 
the surface.  I've decided to use the "buzz,buzz,buzz,buzz" sound for 
informational alarms and the "whoop,whoop" sound for emergency alarms.  
Now if only I could find text-to-speech translator for Yosemite Sam or 
Foghorn Leghorn to make it really unique.

Jon
