I want to make a gear position indicator for my 1974 Yezdi. It is a thoroughly mechanical motorcycle and doesnt have fancy ECUs or Sensors. It does not even have a battery. I want to make a system that can register Upshifts and downshifts solely by reading the change in position of the gear lever.
I am confident in implementing the software and hardware, but I cant narrow down on what sensor I can use to read this movement?
I was thinking of installing two Hall sensors and attaching a strong magnet to the shift lever. One sensor will be on the top, for reading upshifts and one on the bottom for the downshifts. The whole thing will be powered by a lipo battery that will charge off of the rectified current from the motorcycle's electrical system.
Is there a better way to sense it?
I saw the various other posts on the forums where people have implemented gear position indicators, but most of them had sensors already in place and they just had to read the voltage and indicate accordingly. In my case I have to start from scratch.
