Couple of questions.

Any way to use this with the Wideband O2?
Could this be used as a knock detector?

 

Radio Shack has a book by Forrest MimmsIII that has 10x that amount of nfo eritten for the new guys, last one I bought was like $15 once you learn just a little about op-amps and comparators you cna build you own for far less the cost.

I found a stepper motor controller assembly kit, slowed it down a little and now I can take IACs apart proper;y without worry about breaking them.

RS as has a little mimi emgineers section of project dealing with some neat stuff.
