Have just finished building a 5v dc power supply for a music server project and thought I might share here. In anyone feels like building there own all the info is here for those who want to make an excellent upgrade to there raspberry pi, beaglebone, odroid (what I am using), or squeezebox etc. This supply can handle up to a 3A load depending on your heatsink choice and the regulators could be changed for different types if you want a higher current supplied.
I must say this has made a very nice difference to the quality of sound over the standard switchmode supply. It has produced a sound that has greater clarity and less muddled than before. Hiigher frequencies are easier to listen to now and I can tell the difference between each strike of bells or cymbals (everyone is unique and different). The music also seems slightly more dynamic and realistic on the ears.
I have attached the electrical schematic below. It basically just cascades 2 voltage regulators a 12vdc and a 5vdc. The 1st regulator produces 12vdc with fairly low noise level and the output from that feeds the 5v regulator that virtually eliminates any noise that was left, leaving a rock solid 5v supply rail.
