Had a power blackout recently?
... Yes i did mention the voltage and current, 5 volts and 2 amps. So it has to put out a constant 5 volts and up to 2 amps current level.
...
I was also thinking about some sort of extra protection in case the primary regulator put out too much voltage due to some sort of fault. For example if it runs off of a 12v lead acid battery and something went wrong, i would not want it to be able to pump the input jack with 12v at whatever amps.
...For the lead acid if you want to charge every two weeks (which seems like it might be a lot to me though) all you'd have to do is set the PIC up with a nice long count cycle.
