Feasibility of using a 'joule thief' device to power arduino

Hello fellow users,

I was thinking of using a voltage booster device, something like a joule thief, and boost up the voltage from a 'depleted' battery, to power up an arduino uno. Would that be possible, and why?

Do advise me on the direction i should head towards for this project. Any help is much appreciated!!!!!


Would that be possible,



Because it is.
