Hello

Hello, My name is Cristiano Machado, I am from Brazil and I am "mentoring" my son in his experiments. He would like to build a fusor and some day achieve deuterium fusion, but his first step will be a smaller project. He will make the "Make Magazine project" by Dan Spangler (https://makezine.com/pro...
