(...) OK, I hammered on it some more, and made a much more fun video. I updated Brickshelf with some "deconstruction" pictures that show how to build it (hey, I didn't say they made it *easy* to build it): (URL) the video on YouTube, with my son (...)

(...) Hi Aaron, From memory, the boat weights are only about 20 grams each. That's less than 1 oz. So you'd need quite a few. I have used fishing sinkers for counterweight before - you could fit quite a few inside that control room or whatever it is (...) (18 years ago, 27-Jan-07, to lugnet.build, lugnet.technic, FTX)

I would love some suggestions on keeping this WIP project from tipping over: (2 URLs) The tower stays together, with a technic beam running up the back side. But the whole baseplate flexs and tips over with the weight of the overhanging arm. And (...) (18 years ago, 27-Jan-07, to lugnet.build, lugnet.technic, FTX)

Hi Nathan, (...) the RCX rotation sensor should work on sensor ports like all legacy sensors, provided it is supported by the firmware. It would also be possible to build a rotation sensor for the motor ports, i.e. like a NXT motor without the motor (...) (18 years ago, 27-Jan-07, to lugnet.technic)

(...) The NXT motors have built-in rotation sensors, so you could detect a stall condition with no other hardware. You could use the ultra-sonic (distance sensor) or light sensor to detect when the blade passes in front of it, to determine when the (...) (18 years ago, 26-Jan-07, to lugnet.technic)
