First Plasma !
BD139 on present Energetics Forums SEC exciter at 12V, from a standard multi voltage wall adapter. The main coil is of about 450 winds of approx 22 AWG. The top is a tennis ball covered in aluminium foil, to which the secondary’s wire end connects. The plasma will reach out to around an inch 😀 The radio noise you hear, somewhat like AM radio interference, is because that’s really what it is ! radio energy broadcasting. This video also ‘showcases’ my Lightsaber…just a 15W fluoro with a hair styling thing epoxied to the end. BUT….plasma and lightsaber’s, yes, I was a kid in the 1970’s and 80’s 🙂
