DIY 1,5 V to Light Up 15 LED

Introduction: DIY 1,5 V to Light Up 15 LED

About: experimental

One LED minimal need 3 V DC to light up. But on this eksperiment we can light up 15 LED with 1,5 V bateries.

Step 1: Used Toroid From Broken Lamp

images from :

I used toroid from broken lamp, and we can used transistor on this part

Step 2:

This schematic for this project, look at the turn of toroid.

Step 3: PCB This Project

U can used this PCB to make this project

Step 4: Finish This Project

this picture of FINISHED my project

Step 5: Alternative Design

This alternative design for 1,5 V light up more LED.
