How to run 12v led on 1.5v cell

In this project we learn how to run 12v LED on 1.5v cell easy step with circuit diagram. for making this project we need some components.

How to run 12v led on 1.5v cell

Components:

25v, 1000uf Capacitor
12v/1watt LED
BD 139 NPN Transistor
Toroid
Some wire
1N4007 Diode
1.5v Cell
Soldering wire
Soldering iron

Toroid:

1st make Toroid inductor. take a simple dabble wire and turn it on Toroid in 20 time. you can use DSL Cable wire.

Circuit Diagram:

circuit diagram of run 12v led on 1.5v cell

Toroid has 3 wires. Connect dabble side wire with positive side of cell. And negative side connects with emitter. 2nd wire of Toroid connects with base and 3rd wire connects with collector. Now connect diode with collector. Negative side of capacitor, connects with emitter and positive side connects with 2nd side of diode. And at the end connect led with capacitor.

we learn it more better watching video.
