Introduction: Joule Thief With 2n2222a (detailed Tutorial)
Hello friends, today we will make joule thief with only four components
Supplies
- 1k Resistor
- LED
- 2N2222 Transistor
- 10 turns wound ferrite toroid
Step 1:
We connect the (+) pole of the led to the collector pin of the transistor, and the (-) pole of the led to the emitter pin.
Step 2:
We connect our resistor to the base of the transistor.
Step 3:
We connect a single wire of the coil to the collector leg of the transistor. Then we connect the other single leg of the coil to the other leg of the resistor.
Step 4: Powering
We connect the (-) side of our power supply [1,5v] to the emitter pin of the transistor, and the (+) side of the power supply to the junction of the two coils.
