I really like the MC34063 solution. For the learning. (I saved Russel's 
ref for my learning).

The faster way is : Buy a REGULATED powersupply of 12V or 13.8VDV. 3 AMP 
is nice.
  (a 1AMP regulated PS is so easily made with an LM317T that it is a 
waste of money to buy one).

Keyword is REGULATED. (talking about LINEAR powersupplies).
It also serves as a GOOD excuse to buy a nice regulated powersupply for 
other uses.

Regulated because the INPUT of a REGULATED PS is well above the output 
voltage.
Make a connection to the input-filter-capacitor ........
Now you got '2 powersupplies' : One regulated (as made/purchased) and 
one unregulated :
 Tap before the regulator (add fuse).
 I often use a 1/8W resistor of right value instead of fuse, for 
experimenting ... visible, audible, smellable .... cheap too: 200 of 
them for $1.

I bought one 3 weeks ago (13.8VDC output nominal, 13.6VDC actual).
Made for mobile (automotive) cellphone chargers, while at home. With 
car-cigaret-lighter socket .
Philippine made, well-made for a change, nice enclosure and finish. 
Fused. $12.

The unregulated/unloaded voltage was 19VDC.

Any 12VDC or 13.8VDC REGULATED PS will do.
