    Miller- Penny battery

    Sorry to write this here, but there wasn't any place to comment on your only 1 battery hack. You need to change your picture of the battery holder, it is a series run, so doing the hack on a item that needs 3 volts won't work, you need to show a parallel holder where as the two batteries voltage is still 1.5 volt, so one battery would just not last as long.
