I refused to deal with Aliexpress over the recent holidays, because they would not take Paypal. Ira.

Got it -- I should have read the description more carefully, I assumed it wasn't working due to lack of the broadcast time signal. So in reality, you are good to go. I still think WWVB is unnecessary on a 4 digit clock.

I don't trust Aliexpress, too many of the sellers are shady and there is no real buyer protection. If the seller accepts PayPal then maybe you have a shot. Otherwise you are just broadcasting your credit card all over China.

    Terry,
    Just to be clear, when it doesn't receive a signal after 10 mins
    of putting in the batteries, it resorts to a standard quartz clock
    - 32.678 Hz xtal.
    So, it wouldn't need to be modded.
    And, wow, seconds on this flip clock would drive anyone nuts after
    a short time - Far louder than any flip I have heard.
    Paolo,
    -Agreed.  Arduinos are more power hungry.  I was thinking more for
    the idea of still having WWVB in a flip.
    -Yup, looks like Makershed changed the price again from $9.99 to
    $4.49.  Guess it's time to contact them for a price adjustment or
    return.
    -Aliexpress looks good; however, they don't ship to Washington.  I
    have tried to buy several things.

        Thank goodness there is no seconds display! Can you imagine

        It would be trivial to come up with an interface to a normal
        $5 quartz clock movement circuit board that would drive the
        motors. That's what they do in any clock. I would program a
        pic or even a PAL to divide by 60 for the minutes. Divide by
        60 again for the hours, and drive the second motor. Set the
        time at the top of the hour, connect the battery, and go.
        Don't over think it. Not every clock needs to be accurate to
        the second.

        I have many quartz clock movements in the house that never
        need to be corrected, except at the DST change. So they get
        corrected twice a year by default.

        Terry
