[PSUBS-MAILIST] Comms for the SeaQuestor Sub

Thanks Cliff & David, good info.
I might leave my planned screen scrolling buttons off the joystick. Was
going to be hard work putting them in. 
Glad to hear you are getting enough roll to make that function worth while.
I had been talked in to incorporating roll & have a rotating 3rd axis on my
joystick that can be used for that. I have a small sliding top hat sized joy
stick that I am adding to my main joystick for the vertical thrusters, but 
aren't sure that I will have enough range of movement on it to get enough 
sensitivity to hover.
In case you guys aren't familiar with the radio control World; you can program
in an exponential movement from the joy stick. Ie. For an 80% movement of the
joystick you could have the motor only going at 40% of it's speed ( instead of
80%) giving twice the sensitivity for the range where you need to hover off
the bottom.
Cheers Alan

>> Alan, yes I could do this as it is easy to redirect joystick functions though a PLC update. I won't be doing this and the reason is that when I first designed my boat, I had lots of buttons on my joystick.  I could execute MBT blow and flood, VBT blow and flood, correct trim in boat as well as several other functions.  What I found from using it was it was hard to use the buttons.  I would have to take my eyes off where I was going and look down to the joystick to use the buttons which were kind of small.  The joystick was also located between my legs lake like  in an old style airplane.  This made it hard to get in and out of the seat.  I ended up ripping out this joystick and replacing it with a 3-Axis joystick that has no buttons that is mounted along the hull on the starboard side.  My boat is small and this helps getting in and out of the boat.  Buttons are now on panel on the starboard side of the boat.  This has worked better for me.  I think the joystick orientation and function are more important to 'flyers" as apposed to 'K-boats" because of the sensitivity of joystick movement given the widely different GC-GB spreads between the two design philosophies.  For example in my boat, slight movements to the starboard or port sides with the joystick, can cause the boat to roll +/- 30 degrees.  This is Ok if you want to roll but if you are just trying to punch a button on the joystick, it's kind of unsettling.

Once I get all the pieces I plan on running some experiments on the volume and headset control. I have access to 6 mics, and 6 transducers at a pretty decent price. So i may grow my inventory to play  with . My 101 showed up today, and i should have the 2010 and headsets later this week.
