Nice clock! Curious about the capacitor you used for sustaining the DS3231 RTC during power-outages because there is a periodic temperature-compensation cycle every 64 seconds that takes a spike in current. Datasheet says about 600uA for up to 200msec, so each of those will take a bite out of your capacitor. If I did my math correctly, a 1000uF cap will drop around 120mV after each cycle.
In my case, I was monitoring standby current of my wristwatch (nominally < 2uA) with a 50uA mechanical meter, and the temp-comp cycle pegged the meter. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
