I just checked, a simple USB meter says 0.07A/0.08A, not sure how near this might be but not inconsiderable. This includes the LED of a 4 line display, a significant saving could be made by switching

Bob, I do not know but if I I'd think it would probably not get damaged by 6V from 4 new alkaline AAs but for more safety I'd use a series silicon diode. It would then drop 0.6V and act as a polarity

I got the clock and GPS and I am looking at ways to power it. Is 5 volts the absolute max? What is the minimum? If I wanted to power with AA batteries will 4 be too much and 3 not enough? Also I have

Ed, To be completely pedantic about it, every 4000 years is NOT a leap year, so you need a -(y/4000) term. Don't suppose anyone will be around to witness it, especially with any currently working digi

Mine shows C1.03b. However, in spite of the date and time being correct, it shows the day as Thursday while today is only Monday, so it's 3-4 days off. Fred WD9HNU

For those with the 'wrong day' issue, part of my problem, at least, seems to be that whilst my chip is labelled C1.03b, on start up the screen shows the file inside is still C1.03a, so it's not surpri
