I am working on a project where i have a 120v AC to 12v AC transformer (60w max) powering 2x 20w 12v MR11 bulbs.
In the same space I also have a PIC circuit and a couple relays that require 5v DC. I've already made a 5v regulating circuit using a 7805 voltage regulator, but i'll need to supply it with 8v-12v DC. For testing I have been using a 120v AC to 9v DC wall-wart to supply the PIC circuit and relays, but as my project enclosure space is limited, i'm wondering if there is an easy way for me to simply use the 12v AC already present to provide the DC power i need.
Any advice you can offer would be appreciated... thanks!
