Power supplies

Time to get started.  I see 2 reasonable options for power supplies:

  - 9V stompbox-style, possibly with 4.5V reference to facilitate
    opamp schematics.

  - 9V + 5V linear regulator for stompbox analog + uC digital.

  - 5V USB, possibly with some regulator to provide asymmetrical
    supply for low-power analog electronics, i.e. a MAX232[1].

  - 5V USB + rail-to-rail single supply opamps (i.e. MAX494)
