در این مدار به کمک باتری ۱٫۵ و المان های چون یک ترانزیستور pnp و و ۳ عدد npn و خازن ۲۲۰ میکرو و دو مقاومت ۱۰۰ اهم و ۶ کیلواهمی به همراه یک سلف ۱۰۰ میکروهانری(که می تونید از سلف لامپ های کم مصرف سوخته استفاده کنید) و ۶ عدد led مداری ساخته میشود که می تواند ۶ عدد led را روشن کند ..مصرف این مدار ۲۰۰ میلی امپر در ساعت می باشد .

روشن کردن ۶ LED با یک باتری قلمی ۱٫۵ولتی

How to builds.

This project is small and a few part so we can use a perforated board. Or use real PCB as Figure 2. Then assemple all parts on PCB and wiring as Figure 3.

Figure 2 the real PCB of this project.

Figure 3 the components layout.

The L1-inductor is 100uH as Figure 4 I measure it show you. And you can use any type that look like it.

Figure 4 Coil is about 100uH.

Figure 5 The High power 6 LED Flashlight projects for 1.5V AA battery.

Testing
When completed circuit assembly Supply voltage range of 1.5V to the circuit.
Then slide the switch to position ON. The All LEDs will lit, the circuit is ready for use.
As Video below.

I want to see wavefrom across LEDs (all in parallel) through an oscilloscope panel.
We will see that high amplitupe about 3Vp-p it cause LEDs glow.

Note: AA battery we should is kind of alkali house. Because high performance
