Re: Auto Trouble Code Reader Circuit
How about a little PIC processor with an input counting pulses and then spitting out a trouble in real words on a little 16x2 LCD. May be a lot of work just to find out it's time to change the spark plugs.

Re: Is there a good digital designer out there
Kind of reminds me of trying to figure out whether 32 deg F. is melting or freezing. I personally like the logic that hovers in the 2.5vdc area of a 5vdc digital system.<p>WS (used to be from Rolla, Mo....now in NYC)
