I didn’t have a good plan for how to wind this thing, other than that I figured my drill was the best option since I can run it really slow. Digging through my tools from my Harbor Freight rotary tool, I found an attachment with a nice rubber piece a quarter inch in diameter. Looks good at first:<\/p>\n

\"Ready<\/a><\/p>\n

 <\/p>\n

Then I put the spool of wire on a dowel and put the dowel between my sandals and toes to hold it in place. This actually worked better than I expected! I wound the first section really easily and didn’t have any problems with anything breaking. One the second one, the rubber piece started slipping, but I managed to salvage it enough to finish off the second coil:<\/p>\n

Looks like I do need to find a way to make sure the coils are the same size. I didn’t have too much time, but I did a quick test. The resistance on the first coil measures out to ~6 \u03a9, which is about what I expected. I should be able to run at 6V and get 1 A through it without any problem.\u00a0This time I was prepared for the coil to get warm, so I setup my meter to monitor the temperature.<\/p>\n

At 5V, I could feel a little pull the nail I am using as my shaft right now. I’m sure I can find something better, but that’s all I have that fits in there right now. At 10V, I could feel a significant pull on the nail, but then the temperature jumped up to 100\u00b0F. The coil didn’t actually feel warm, but I shut it all down because I didn’t want to risk destroying it.<\/p>\n","protected":false},"excerpt":{"rendered":"
