Re: [PSUBS-MAILIST] [Fwd: take some time and view my web sites...]
Hi,
I smell a topic for the 2005 Convention. Topics actually.
How about breaking down the various components of a submersible and
discuss them each in turn.
Motor controllers would be of interest to many. Show a schematic and
walk through its parts. Discuss perf board verses PCB construction.
Debugging. Calibration. Specs and requirements. Alternative off the
shelf sources....
Regards,
Ray
