Here are the materials required to make possibly the easiest and best land camera battery conversion ever. You will want an LED torch, an old 9 volt battery snap, a Velcro cable tie and a soldering iron.... Let's say I want to make a battery operated volt meter then I would prefer a buck regulator such as lm2596 (eats much less battery) . Mostly buck regulator are preferred over linear drop out regulators because of their ability to deliver almost 90% efficiency whereas ldo has much less efficiency ,Which in turn burns out power through battery.
