<pre class="k9mail"><br />Hi Alec,<br /><br />Pitch and roll on a K-sub are negligible but the sensors are "free", <br />part of the electronic compass, so I added them to the display. The <br />pitch might come in handy to help with longitudinal balancing. <br />Roll...well if I ever get stuck on a sloped bottom I can radio to the <br />rescue divers "you can't miss me, I'm the sub leaning port at a 25 <br />degree angle".<br /><br />I think Cliff pointed us to a depth sounder/speed combination sensor <br />that he is using which would work well for altitude over bottom. It <br />would be easy to add that into the software, just a matter of getting a <br />unit and testing it.<br /><br />One thing that the demo fails at is my implementation of MATILDA, audio <br />warnings corresponding to the yellow/red alerts that are displayed for <br />various sensors. A yellow alert sounds a gentle "ding-dong" sound <br />followed by the sensor name spoken by a computerized voice (female
of <br />course) and a red alarm sounds a high pitch smoke-alarm sound followed <br />by the sensor name spoken by MATILDA. I was too lazy to set things up <br />to record the audio for this demo but will do that at a later date and <br />of course will have it available for the convention in July.<br /><br />Jon<br /><br /><br />On 4/1/2016 9:20 AM, Alec Smyth via Personal_Submersibles wrote:<br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> That's gorgeous! I'm curious though about the pitch and roll, it would <br /> seem you wrote it for a "flyer" sub. One data point that would be a <br /> great addition would be altitude over bottom. Not sure if you've <br /> figured a sensor for that, but if there is one it would be great to <br /> display right next to and analogous to depth.<br /><br /> Best,<br /><br /> Alec</blockquote><br /><br /><hr /><br />Personal_Submersibles mailing list<br
