I once found a joule thief online...did a tweak to it
on a fresh 1.5vdc AA battery it can run almost 7 days straight...on a battery considered "dead" by most other devices (.9vdc or lower) it will run 2-3 days
Very simple to solder (great kid soldering tool), super cheap, and made with readily available components
