Hey guys! New here but been lurking around for quite a while. I'm currently doing a project more for fun than anything else, putting a Speeduino on a chainsaw!
I am working to try to come up with a crank position sensor, which is proving to not be an easy feat. My current plan was to mount 12 evenly spaced magnets (well 11 actually for the 12-1 pattern) around the flywheel and use a hall effect sensor (probably a 3144) to be a pickup.
My questions are, has anybody ever had a similar setup or seen one working? Also, will it matter that the magnets are not the same width as the area between them? ( To visualiuze, |||||||o|||||||o|||||||o||||||| would be the surface of the flywheel with o's as mangets)
Thanks in advance!
