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

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