5V USB – Mini Tesla Coil Circuit Using 2N2222 Transistor || Practicing Electronics

How to Make a 5V Mini Tesla Coil with a 2N2222 Transistor (Slayer Exciter).
😂 This time, instead of reducing the coil size, I opted to use a smaller transistor. I chose the 2N2222 to build this circuit and see what the practical results would be.
In the video, I used a 5V power supply and a 12V transformer. At 5V, the coil can be operated safely without issues.
Although the project runs on low voltage (5V USB), the circuit generates high frequency and small sparks. The 2N2222 transistor can heat up if operated continuously.
⚠️ Avoid connecting it directly to computer or laptop USB ports; instead, use a mobile phone charger or a power bank.
ℹ️ The secondary coil wire connects directly to the transistor’s base (this detail was missing from the video).
This project has little value because it is an experimental idea. The goal was to use a BJT transistor to build an SSTC (Solid-State Tesla Coil).
❓ Fun fact: The world’s smallest operational computer.
The Michigan Micro Mote is smaller than a sesame seed and features a complete system, including a microprocessor, memory, and a miniaturized battery. Its tiny solar cell can charge the internal battery using only ambient light.
