This ignition coil circuit produces a stable high-frequency arc, generating extremely high temperatures, it can easily ignite combustible materials such as gas and paper.
This transformer produces high voltages in the inner windings and low voltage in the outer windings. The transformer has two primary windings, one of the primary windings is stranded copper wire, and a fine copper wire for the feedback winding. The secondary winding is the high voltage output.
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 of12V), 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.
