<div dir="ltr"><div><div>Hi Cliff,<br></div>Its been slow going as I am finishing building my home. Should be finished in 45 days. But I have been making progress as I learn PLC coding and ladder logic in the evenings. Currently I am working thru the flight Joy Stick switch controls combined with a 4 position joystick base to control the (2) forward canard wings, (2) vertical thrusters (2) horizontal thrusters, and (2) vectored rear thrusters to have a flight experience. I spend many hours in the evening when my wife is not looking waving my hands thru the air simulating flight and then coding the switches needed to make the maneuver. I'm sure it would be entertaining to record a video. I am curious, are you using any gyroscopic sensors for pitch and roll? I'm thinking I need to have some build into the coding so as to limit my human abilities as safety overrides. <br></div>The next step is to get a bench setup with the joystick and canard wings to run tests on the coding and for flight training purposes. Just need to finish the house first. Mean while I'll be waving my hands in the air for a while.<br><br><br><br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div>Best Regards,<br>David Colombo<br><img src="http://static.squarespace.com/static/533310a9e4b0fba62008a464/t/5339c1f2e4b041bac4e25d1b/1396294132055/?format=500w" height="110" width="200"><br>804 College Ave<br>Santa Rosa, CA. 95404<br>(707) 536-1424<br><a href="http://www.SeaQuestor.com" target="_blank">www.SeaQuestor.com</a><br><br></div></div></div></div>

When I first installed life support on the R300, I had sensors distributed all over the boat. What I have move to is packaging all the Life Support related sensors in a single electrical box I call the AMOC module. AMOC is an acronym for Air Management and Oxygen Control. This made it easier to maintain the system and made it easy to bench test. I feed HP O2 from an external tank to this box. It in turn breaks the pressure and emits the O2 to keep the mole percent balanced. The PLC interfaces with the AMOC unit to monitor and control the air in the cabin. If you are interested, send me your email address to <a href="mailto:cliffordredus@sbcglobal.net" target="_blank">cliffordredus@sbcglobal.net</a> and I will send you the DCI for the drawings associated with the AMOC unit and the drawings. The axial flow scrubber I use is the same one Alec used for Snoopy. It has worked great. The PLC ladder logic code around the life support system is pretty straight forward. What I like about the system is that it automatically compensates for different sized humans in the boat but yet retains a manual mode in the event both the main and auxiliary power are lost. The assembly drawing for the AMOC unit details all the sensors as well as all the Swagelok fittings and circular disconnect. This unit should work well with the AutomationDirect DoMore CPU you have.</div><div><br></div><div>Cliff</div><div><br></div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 2, 2017 at 7:50 PM, David Colombo via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.<wbr>org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Cliff, Thanks for answering the question I was just going to ask.
