    OK, here is my plan:

    A 7V @ 20mA booster from 5V, powered by USB.

    http://linnix.com/larkin?vcc=5

    While connected, it will be charging a 6V battery.

    When disconnected, the battery will be dropping from 6V to 4V

    http://linnix.com/hyde?vcc=6
    http://linnix.com/hyde?vcc=4

    The output will be boosted and regulated to 30V @ 1mA. This should be
    enough to run the quad op-amp LM324.

    Notice that the single stage Larkin booster can deliver higher
    current, while the dual stages Hyde booster can deliver higher
    voltage. The Hyde booster has a nice smooth transient curve and less
    noisy as well.

    Be patient with the links, it takes a few minutes to load and run
    spice.
