Mag coupling version 3.0 vid (updated new video 1/25/15)

Making progress on my magnetic coupler idea.
Here was version 1.0: the proof of concept:
And here is today's test (version 2.0):
It uses an 1100 gph bilge pump motor, some 3D printed parts and fits inside 1.5" sched. 40 PVC. My motor controller is just an Arduino shield for testing and I already cooked 1 of them so I haven't cranked it up to full power yet, but I am sending it almost half power and it seems to have pretty good torque. The motor doesn't seem to heat up at all (mostly because the board is the weakest link I assume). I'm just sending 3-4 vdc at less than 1 amp so far, but it's working!
I plan to play with the size, pitch, and number of prop blades in order to find the best option. Once it's done, the plan is to have a completely self-contained and sealed thruster design that you can pretty much just attach to your frame wherever you like.
Total cost for the sealed unit: under $50.
My plan is to build a test stand and see what kind of numbers it's putting out and compare different configurations of thruster blade.
It's coming along nicely though...
What do you think?
