As some of you may know, I am trying to design and build my own tachometer for my scooter. I've gotten to the point where I need to somehow get a reliable rpm signal from the engine. After many different tests on different electrical parts, I've come to the conclusion that in order for me to get a nice, clean voltage pulse for every rotation, I have to do something like glue a very small magnet to the flywheel to get a signal.
Before you ask, yes, I tried to use the magnet that the ignition trigger pickup uses; it wasn't strong enough.
I need to know if gluing something that weighs about 0.6 grams (without glue) to the flywheel will cause some sort of catastrophic damage. If I need to, I could glue a second magnet of the same weight to the opposite side of the flywheel.
