Dual Power Circuit for ProtoStation

I'm working on a new Prototyping station that will be both battery and DC powered.  I'm looking for ideas on how to build the circuit so that it switches cleanly between battery power and DC power as well as charge the NIMH batteries.

More info here - https://eddywright.wordpress.com/

Here is the circuit so far, I left off a lot of ancillary components like filtering and noise suppression for sake of legibility. I would love suggestions on improving this that anyone may have.

Voltage Regulation, Part 3 of 3

This last part presents some discussion aout voltage ripple.

The Output Ripple

The regulator is able to provide the required voltage as it is adjusted using the variable resistor, but sometimes the voltage is not as clean as it is needed. How much this affects the functionality of the circuit depends on the application. In some cases the unclean voltage has no effect, but in others it can wreak havoc and create a scenario that is difficult to troubleshoot.
