there was a great thread started by Kormex about making a knock measuring gauge, but then it died rather suddenly...
I'm not going after anything as ambitious, just an led that would light up when there's any significant knock. is there an easy way to do this?
like a FET with Vgs of right about what knock produces, coupled with an led?
thanks
