[PSUBS-MAILIST] welcome Ian

[Alan via Personal_Submersibles]

Welcome to Psubs Ian!
Ian is a Canadian robotics & electronics instructor that I met through a 
couple of his courses I was taking on "UDEMY" an online short course provider.
He aims his courses at 11 year old level lol.
Ian is a robotics engineering graduate who has been a science & technology
Instructor for 30 years, worked in R&D & wrote a book on video production.
Of particular interest to me is that he has built an underwater manipulator.
By the way Ian, Hank is a fellow Canadian.
Regards Alan

> For the record, I do have the math skills for buoyancy. And every single ROV I tested and tried to pre-balance it before a test dive. I don't think I ever got it right once. It was always too light. Came back to the science camp after the test dive with one and one of the counselors asked how it went. I told him "Oh, it wasn't heavy enough to sink." He laughed and said "I'll be if you built a boat, it wouldn't float!" Four months later my pontoon boat I built to launch the 300 pound ROV from, sunk in a storm.  lol
> The big naval submarine construction ports have an entire team of people with a boat load of computers whose sole job it is to weigh every single bolt, piece of equipment, even the volume of the welds, to get the buoyancy right. So I'm with you when you say the best way is to stick it in the water and add the weight till you get it right.  :D
