These days the input to whatever you try to detect a switch activation with ends up being low voltage at some point. It's a job to differentiate between what you do want to detect and the noise that's present all the time on the input signals.
    I guess you don't have a scope trace? From what you describe I'm gathering it is something like:

    when the switch is off you see a low duty cycle signal between 0-12v and when the switch in on it is a high duty cycle signal again 0-12v where no false period is longer than say 10 msec?

    That being the case I would want to detect duty cycle ( an average time varying quantity). Basically counting up and down cycles over a finite sliding window.

    You can do that by analog integration with a low frequency pole (a few Hz) and operate on the minus 1 slope ( you said you did a second order filter which would be a double integration ). I would tend to want to do that by performing an averaging in software. So you clamp/current limit the voltage input to the 12v range mainly to protect the controller, and now detect duty cycle . No debounce required.

      If enough people are interested in (and can agree upon) a board solution, apparently you can get that guys to make you a few. I havn't checked out his site yet, so proceed with caution.
      I have used ExpressPCB for some of my projects, and I like it. They have a design program that is not all that hard to use, then you submit the drawing to them, you have boards back in just a few days.

        Updated the first post with an 'almost' finalized design and description of how it is intended to work.

          Why not just buy a new box??

            They are prone to failures...which is why he was doing the reworking with modern parts.

            I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

              Suggested list for the original unit is $460.28 discounted to $337.00 at G&S Suzuki

              How many would you like to by at that price?

                    what's going on here?
                    i have one of these cigarette pack size metal boxes.
                    i'm sure it works as it was removed when the bike was only 10 years old...hmmmmm
                    good...no good...???? lol

                      Sorry Jim, I just saw your inquiry. Nope, been on the back burner since last year. If I get time I'll get started cracking on it.
                      Might make it manual operation only...

                        You know, I'd not be bothered about a distance interface, but a simple time-out would do me. That alone would greatly diminish the occasions when I would leave a blinker going. Not that I ever do such a thing, anyway.

                          You know, one possibility that occurred to me was -- eliminate the whole ignition interference problem by running with a simple bicycle-computer style reed switch on the rear wheel somewhere, like alongside the brake rotor. It works great with $10 bike computers...

                            I haven't forgotten about his project. Learning the code is the hold up.




                            Requires learning Python which I think my son can help me with.

                              I thought you were going to use a PixAxe? Here is free sw to use for BASIC or other model based languages.
                              PICAXE Editor 6 is the recommended Windows software for programming, testing and simulating BASIC, Blockly and flowchart programs for PICAXE.

                                That was my original plan.

                                Now I'm looking into the Rasberry Pi. I'll have a look at your link tonight.
