Hello,

Just wandering if anyone ever did a project that require powering from a single 1.5v battery like the one used in watches or wall clock.
Just wandering how they manage to get the device working from 1.5v or do they use a boost converter to 5v. If so how is the boost converter made. I looked into my wrist watch and could not see any coil or obvious boost up converter of any kind..
