00:00Today, we're exploring the fascinating world of the Jewel Thief, a simple yet

00:04ingenious circuit that can breathe new life into seemingly dead batteries by

00:09amplifying their remaining power.

00:11Despite its seemingly magical abilities, the Jewel Thief is nothing more than a

00:15voltage amplifier, consisting of just five electronic components, a 1.5 volt

00:21battery, a resistor, a bifilar toroidal coil, an NPN bipolar junction transistor,

00:28and an LED.

00:29But before we delve into how the Jewel Thief works its magic, let's quickly

00:33review how batteries function.

00:35Batteries rely on chemical reactions to generate a consistent voltage over time.

00:40As these reactions become less efficient with use, the battery's voltage

00:44gradually decreases, eventually rendering it unable to power devices

00:49effectively.

00:50However, there's often residual energy left in the battery, waiting to be

00:54tapped into.

00:55Enter the Jewel Thief.

00:57This circuit exploits the remaining energy in depleted batteries, effectively

01:01stealing jewels to power low-voltage devices.

01:05At its core, the Jewel Thief operates on the principle of positive feedback,

01:10continuously amplifying the voltage until it's sufficient to illuminate an

01:14LED.

01:15Here's how it works.

01:16When the circuit is initially powered on, current flows through the resistor

01:20and the base-emitter junction of the transistor, causing the transistor to

01:24conduct current between its collector and emitter terminals.

01:28This in turn allows current to flow through the bifilar toroidal coil,

01:32inducing a magnetic field.

01:34As the magnetic field grows, a voltage is induced in both windings of the

01:39coil, boosting the current flowing into the transistor's base.

01:43This positive feedback loop rapidly switches the transistor into a fully

01:47conducting state, allowing current to flow through the LED.

01:51However, the LED only lights up when the collapsing magnetic field induces a

01:56voltage of sufficient magnitude to overcome its forward voltage drop.

02:00This process repeats in a continuous cycle, with the LED appearing to remain

02:04constantly illuminated to the observer.

02:06The speed of this cycle can be adjusted by varying the inductance of the

02:10toroidal coil.

02:11In essence, the Jewel Thief breathes new life into seemingly spent batteries,

02:17demonstrating the ingenious ways in which simple electronic components can

02:21be harnessed to solve complex problems.
