[chbot] Magnetically coupled ROV drives

[kerry at manukadesign.co.nz]

Hi all, last year I posted here about building a fishing torpedo,  
someone mentioned that many drive systems use magents to drive the  
prop and keep the electronics dry.

I just came across this website which nicely describes who to go about  
the construction of such a system. It's from an open source ROV  
project which looks quite interesting in itself.

Regards,
Kerry
