I found a 3.3v voltage regulator (from an old wrt router that died), snatched a few parts from it (Diode, coil, voltage regulator, cap), and soldered them up into a tiny regulated power supply.
This site tipped me off to the VR

And looking over the datasheet, they had a typical circuit, which happened to be exactly how Linksys used it, so I just took the parts connected to the VR, and applied them based on the schematic in the datasheet AP1501-33K5 datasheet(7/7 Pages) ANACHIP | 150 KHZ 3A PWM BUCK DC/DC CONVERTER
I wasnt sure about the input cap, so I omitted that part, and it seems to put out 3.4v with no load.
The 12v brick I used said its .3a@12v, the VR is rated at 3a. Im not sure what my current needs are, but I think this will be more than plenty.
