Seasnake,

Well you`ve already seen my dive light, which was an inspiration after designing the lights for my ROV (they should be able to go down to 50m, based stress analysis).
Built lots of other toys before, but not many for diving. Built serval dive computer interfaces, for Sunnto & UWATEC.

I like a good challenge, so figured the ROV would be good...and hopefully useful too. Has got some concepts for a baby version, but will depend how sucessful the big one is first.
