[time-nuts] Oncore battery backup

[paul swed]

You could. But its funny I have been reading over the last year or so thats
its actually not simply attaching a resistor and diode to charge the super
cap effectively. Yes it will charge but to what effective level.
Give it a try if it works it works hopefully well enough. Me I just need to
find that pin and connect a disposable battery.
