"Looks well thought out and nicely made.  Are you selling these?  If so, where is your website so I can learn more?"

"@Kevin - Why not use a couple nylon cable glands?  Just be sure to mount them on the topside so you don't have to worry about a hull penetration."

"Getting closer!  I just received my parts from Rusty and am waiting on a PixHawk that should arrive next week.  Once I have everything it'll be time for me to sort out the electronics for my build.  Got to say I'm pretty impressed with both the…"

"Perfect timing, I need a PixHawk for an underwater drone project I'm working on.  BTW, how long does it normally take 3DR to process an order?  I placed my order early yesterday and its status is still "processing"."

"I like the look of that 6 foot kayak.  With a maximum carrying ability of 150 lbs you should be able to carry a good sized battery bank.So with no rudder and two thrusters, will you mount the thrusters in a fixed position and turn "tank style" or…"

"@David - That's pretty impressive.  What voltage are you running the T200's at?"

"I had to watch the second video before I realized what was going on.  The position control is really impressive.  In spite of pushing the ROV, it maintains depth almost perfectly.  Most commercial ROV's I've flown are barely able to maintain a depth…"

"A turns counter is a useful addition, but on a battery powered micro ROV where your source of power is limited I think a disconnect is still the better way to handle this...  although an even better solution would be to have both.  :)"

"I'm with Kevin, I highly recommend a disconnect fitting at both ends of your tether.  If you don't you'll wish you had.  My Deep Trekker didn't have one and it was a PITA to have to spin the ROV around to take out all the twists at the end of every…"

"I just happen to have several tins of lead air gun pellets that I will likely use on my build.  If I didn't already have them I probably wouldn't consider using them as I'm sure there are cheaper sources for lead out there.
Don't forget to leave…"

"Excellent news.
FYI, SeaBotix recommends testing at 10 in Hg for 10 minutes (page 13 here:  http://www.seabotix.com/service_support/manuals/LBV200-4_manual.pdf )."

"Thanks, time to go shopping.
By the way, I used a HVAC pump like what Rusty is using for vacuum bagging composites.  Got mine for $25 used from a HVAC repair shop.  Worked like a champ."

"Wew!  Well that is a relief!  Glad your potted fittings seem to be well sealed.  I would be interested in learning more about the pump and other fittings you've settled on for your test.  I may need them when I get to that point in my build."
