Re: [PSUBS-MAILIST] Your Homebuilt Submarine in our Video?

Pat,

Actually, it was easier than using Minn Kota's existing controller and much 
cheaper as well as better performance. The potentiometer I use doesn't handle 
much power (less than 144 milliwatts) since it controls the duty cycle of the 
power switch operating at 20 kHz. The electronics are contained in a pressure 
compensated, dry air space.

On the video, can you handle mini DV video?

Best wishes,

Ken Martindale

 (RE: MOTOR)  In the NAUTILUS MINISUB VIDEO, we'll touch on basically
 everything from design to dive tests.  There really wasn't anything exotic
 about the E-motor part of it, though.  I would imagine yours was quite a bit
 more difficult, since it's in a wetsub and all.  For example, I know you're
 running a Minn Kota lower unit; I'm wondering what kind of potentiometer
 you've got, and how you keep your vital electrics dry in a wet environment.
