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.
