Yea, had not touched it in several days myself .. was repairing a watch... need better tools, but it works again.. We are in for some nice hot days here, 35 degrees C here predicted for Monday. 95 F? As to that fusor, some old electron guns from color CRTs.. good focal point, 35 kV should be no problem need a good lab and mechanical man. Maybe some electron guns from old film scanner CRTs, those used even higher voltages. electrons; more basic and simpler than light. Farnsworth was a genius.
