    I came across a datasheet for LT1107 switching power regulator.

    Why I think it's good for this project?

    - it can work in a boost configuration from just 2V in.

    - it can output a negative voltage.

    - it has a fixed output voltage of 12V or 5V.

    - it has a built-in configurable low-battery detector.

    I'm going to buy a few of these and try to build something. The typical application in a datasheet looks straightforward, so I don't even need to change it.

    As a sidenote, I also found a very cool 4xAA battery holder made by Bulgin. It's quite expensive, but can be conveniently installed in a DIY enclosure.
