Chainsaw Repair

with you....think it would work.  the bolt through hole would also help when fabbing an adjustable mount. 

it has to be sturdy vibration and wobble free from what i have tested so far.  has to hold against magnet pull.  has to be very close, about  .020" or so. 

the reason for the mic or headphones for sensor, is it what was recommended in one of the versions of the software.  another version recommends making a simple wound coil.

hope an electronic whiz could explain the signal better.  have read that there are 2 differing kinds of sensor types.
one is mag to mag.  another uses anything out of iron to mag.  have a couple of links on this i will post.  biggest thing i am guessing is it just has to be clean spike?

found that running my laptop on the charger causes some waves.  60hZ.  maybe this is the same hum you get when running an adapter charger on guitar effects?  on battery power he sig is clean on the laptop.  the mic/headphone is way sensitive, and needs attenuation or it goes off the scale.

no matter what anyone uses.....on a newer laptop, thinking you will need the things i have ordered to make it work to plug them into the laptop.

will post some dirty signals up to show what does not work so well.
