Fractal wood burning, also known as creating Lichtenberg figures is the art of burning lightning or tree like figures into wood using high voltage electricity. The high voltage electricity is generated by a transformer, usually a microwave oven transformer, a neon sign transformer or an oil burner transformer. These machines are very dangerous and potentially deadly if you make a mistake when using them. I do not recommend that anyone do this due to the danger involved. I am aware of the risk and have chosen to take it. I will provide information and tips on how I made my wood burning machine and my technique that I use burning Lichtenberg figures. If you do decide to take up this hobby, please be careful and educate yourself on how the systems work and of the dangers.
