Step 2What you need:
Some of the things you will need are
1) Laptop power supply, or any other suitable "power brick." The one I used is actually a regulated 12V 1.25A power supply that was originally for a VOIP phone.
2) A couple of LM317 IC's.
3) resistors, caps, and pots/trimmers to build the LM317 circuit. Because I had 500R trimmers handy, I used 50R for the fixed resistor. This provides for adjustment from 1.25V up to just above 12V. If you have any question, try Google.
4) A suitable enclosure.. such as this nifty case that used to house a travel alarm clock.
To do this MY way you will also need:
1) a glue gun!
2) some machined pin IC sockets and 26-27 awg solid core wire
3) a breadboard power bus strip.
