This works vey well - TWO supply rails shown - you only need the 5V
Sense the voltage drop BEFORE the regulator(s)
Poll the analog input regularly - I use this and have time to save about 1.5K to EEPROM
Quite a few in the field.

Whats the reason for the capacitors on the regulator inputs and outputs being as low as 100pF ?
100nF would be more normal.
GOOD SPOT...
They are in fact 100nF - a typo that has existed for several years !!!
Thanks
