The thing pictured above was an attempt at a "motor" that I created on my printer. It has three pairs of magnets gripping three fan blades in a rotor and a coil wound around a stator. The motor doesn't run, of course, because I didn't pay homage to the right hand rule before building it, and I shamelessly (or perhaps shamefully lol) post it here for your enjoyment as an example of yet another idea that didn't quite make it in prime time. That's OK though, because if you look closely you'll see that I figured out some cool stuff, like how to wind a coil on a form (and how to make that form in the first place), how to get magnets to stay put by having them grip each other in pairs, and how to make moving parts fit together in a single print.

So there was experience gained and lessons learned on this effort also (and iI did do it from thought to failed test in one day) as in my previous work. Don't worry, I'll stop shooting arrows all over the place and hit the dang target if not the bull's eye pretty soon, just you wait and see.

I thought for some reason i'd make a boat propeller for my water craft drones. I have a bit of a notion to combine the moving part with the engine when possible, so that led to the magnetized propeller concept. It would be cool if you could have just a magnet or iron core thingie in the water and all the coils and electrical what-not on the dry boat hull (suppoedly dry!).

The easy way to fix this debacle is to turn it into a stepper motor, which I have built before like this. I can just arrange some coils radially and set those magnets in radially also and with the right control setup using an ATtiny95 mocrocontroller chip and an L293D motor driver chip just zap those coils in the right way and the thing will move, I've done it before. It just requires a core to make it work properly so the ciols would need a magnetic core each and that should do it.

I think I'll redesign this motor that way. More to follow...
