Hi David. Keep the good stuff coming. That's a nice little unit, and
adaptable to several uses. Do you have any ideas on a small submersible
electric motor case ? I saw a design a while back where a guy took a
battery screw gun and used it with a threaded screw mechanism to operate a
grabber hand for an arm. It wasn't sealed at all, but he said the motor was so
cheap that when it fried, he just replaced the screw gun. The linkage was
simple, and all home made with plexi sheet and threaded rod. If a good motor
case could be fabricated cheaply, it could have many uses. Maybe even operate
rudders. ( maybe not very quickly though.)
I like the hydrophone a lot. Good work. Frank D. Need a new ride? Check out the largest site for U.S. used car listings at AOL Autos. |
