    I can remember the big pound notes before they brought out the smaller versions, and the old pre-decimal pennies and sixpences. Not the white fivers though!

    To be honest you guys have lost me with this thread pretty much understand the electrical components :)
    But you’ve totally lost me when talking
    10 shilling notes
    Sixpences
    White 5 pound notes
    Pennies

    Thanks Russ, as ever, good advice! I think you’re right, a bit of signal conditioning and a couple of diodes would do the trick. I was thinking the hysteresis of a Schmitt would clean up the secondary “bounce” pulses. I guess with a large enough pot/resistor and a zenner you can “tune out” the secondaries. Good food for thought. Thank you.

    I have just ordered an opto isolator. Never played with one before but my speedo needs one to pick up the signal from the handbrake switch to update the ODO into EEPROM.

    I would quite like to build a data logger for mine but there is really no point as im using the factory ECU and will be looking at an AFR reading all the time. Once I migrate to a standalone ECU it would be more valuable but considering building a Speeduino for it at which point everything is logged anyway!

    A friend of mine is building a Zetec turbo for his MK1 Escort and I am putting a Speeduino and wiring together for that in exchange for some fabrication work on my Z which means I will have it on the road sooner than I was expecting.
