Hello Les,

Thanks for the information about the Truemeter counters - £15.84 plus carriage, whatever that is! I don't think the cost difference between one of those counters and doing it with a PIC is going to be very much, so no great advantage there.

I will be using only three digits (that being all that can be seen through the counter 'window'), so half of one of those counters would be wasted! Also, the digits are quite close together which might make fitting it with only three digits showing difficult, as part of the fourth may be visible, if the digits weren't sloping, it would be a bit easier.

Doing it with a PIC would eliminate the need for a battery to retain the count, I realise the Truemeter current drain is very small, but I would rather not use a battery, if at all possible. Overall, I think doing it with a PIC will be better, and it leaves open options for other features, which wouldn't be the case with one of the Truemeter counters.

Thank you for taking the trouble to provide that information.

Regards,

Dave.
