At the prices of some of the PIC chips nowadays, I'd be inclined to 
just  give it a go and see what happens.  Decouple and provide diode 
protection where practical - ordinary (fast) diodes for reverse voltage, 
Zeners for overvoltage.  Optical isolation is always good if you can do 
it.  Note that many fully-isolated SMPSs use opto-couplers on the feedback 
loop.

Remember, the smoothest power supply you can get for your control 
electronics is a battery.  Sits in the box with no external connections - 
read "antennae".

Anyone know if you can still get those feedthrough capacitors that used to 
be used in radio chassis?  Thought it would be a good way to get stuff in 
and out of a box like this, for decoupling purposes.

My $0.02 or in your case, 0.6p ;-)

Cheers
