/diy/ - Do It Yourself

First I suspend nylon fishing line from a small 12v motor with a hook attachment a weight keeps tension on the line. Then I wet the nylon with some water and then I pin an equally long piece of nichrome wire at the top and bottom of the nylon. Then I spin the motor which causes the nichrome to wrap around the nylon, I visually watch it until the wire seems covered. Then I unpin the nichrome which stays via tension alone now. Finally I continue to spin the nylon until it doubles over on itself and they are done. I put two strands together to make a helix shape in the pictured example. Checkout this video for a non-nichrome version tutorial.

These have a duty cycle of about a minute, they take 16V at 4amp. Here are some pictures of producing hydrocordial muscle which though weaker are very fast.
