Hardly useless. The question is how difficult would it be to put 3 or 4 more bobbins to the system? This would be perfect for making Lenz Wire.
Great project. Any thought of making the code and design available? Thanks for sharing this. Doug
Pretty slick! I would be nice to see a better view of how the bobbing shuttles move form one ring to the other. If nothing else it just increases my interest in 3D printing, there are some cool parts printed here.
