Lichtenberg Wood Burning
This setup can make some beautiful art, but it is also deadly. I was well aware of the risks heading into this project and I took extensive safety measures, do not attempt. When a salty solution is painted over the wood, the electricity has a lower resistance path and is free to gouge that path into the wood as it goes. This method is capable of making much better fractals then shown. I did not have access to the optimal solution or transformer. I am using the same microwave transformer along with a half wave voltage doubler. I'm not sure why it burns fractals outward from the path of least resistance, but I'm not complaining. :)
