Here are the key features of this kit:

• Dual windings: The transformer consists of inner windings that produce high voltages and outer windings that produce low voltage.
• Primary windings: We've used stranded copper wire for one of the primary windings, ensuring optimal performance.
• Feedback winding: The feedback winding is made of fine copper wire, enhancing the efficiency of the ignition coil circuit.
• High voltage output: The secondary winding serves as the high voltage output, enabling powerful ignition.

Note:

This DIY product generates high voltage & high frequency, similar to an electric mosquito swatter. If you touch it directly with your hand, you may experience an electric shock sensation. It is important to understand that this DIY kit operates on the same principle as the electric mosquito swatter.

Please exercise caution and avoid direct contact to prevent any potential electric shock.

Precautions for product use:

1. After successful production, the transformer can be sealed with epoxy resin or insulating wax to be used for a long time. The plasma in the air can cause the coil to break through and damage due to the lack of air insulation.
2. The input voltage of the kit is 3.7V - 4.2V. If you need to increase the input voltage (to a maximum of 12V), you need to increase the feedback resistor resistance (by default it is 120 ohms), otherwise, the transistor will burn. The feedback resistance can be increased to 150 Ohms ~ 1.5k Ohms depending on your voltage. If you do increase the voltage it is recommended to apply a larger heatsink to the transistor.
