What happened is that two guys comes to me, says "Make me a ROV that fits in this plastic shell I made", and I do. Then he goes to maker faire NY to show it off. I do not go with him because a friend of mine had a panic attack and needed someone to stay home with her. Next thing I know, the ROV had been done by the two guys without my input.

I do not mind them making money on the design (which has since been improved) largely because guy #2 had just gotten married with a baby on the way, but the lack of attribution irritated me, so I had a talk with them and with someone from Make about it.

The fact that they changed the design a little means that the ROV's battery life is about two thirds of what it was supposed to be, and cannot recharge while stopped underwater.

I may release the intended version next year if there is any interest.
