1.2V Ultra Bright White LED Driver

As u all know u can light up a small LED bulb using Two batteries ( 3V )

But in here LED is light up by using one 1.2V Cell. This is a energy booster circuit.

This will cost u less than 30/=

1) Ultra Bright White LED - 10/=
2) Two Transistors - 10/=
3) 47pF Cap - 0/=
4) 47uF Cap - 2/=
5) Resistors - 1/=
6) 100uH Inductor - I just recovered it from Blown Up PC Power Supply Unit
7) Diode - 2/=

SEE HOW BRIGHT IT IS

Two White and Red LEDs in Series

WOW >>> Another Nice JOB....

 

[KishanW]

how long will the battery last ?

 

[ruka max]

wow maaaaxaaaa

 

[madhu4gr]

maxaa mcn tnx

how long will the battery last ?

The Problem is this whole circuit suck out nearly 250mA.

So its depend on ur Battery capacity.

My Battery is 2500mA.

So max time is more than 8 Hours at max BRIGHT

Oh i seee. But im project super project crazy

wow...its gr8

good work dude.. thanks for the circuit..its good for night i mean when the current is gone..if you can please develop this circuit to light up only in dark(using LDR) and give it to us thanks so much

 

[SAN_APIIT]

really interesting...

THx for ur post

Gonna need to try this 1,

If u really want i can upload full automatic 30 Withe LED Project also with PCBs.
