Guest guest Posted December 31, 2001 Report Share Posted December 31, 2001 First you will need to ask Jimmie Holman how he calculated the resistor for the base current to drive the transistor. If not then you can step up to the next level and use a MOSFET it's faster and has a lower R-on than a transistor. With new studies this design that you are using has been replaced by new information. Jeffers dave@... I have the jimmie holman setup and i just recieved barry allreds double bubble e gas tube . Mine is putting out a sky blue glow with violet on ends. Its a beautiful bulb it lools good even when its off. While fooling around with lower freqs ie 15 to 75 hz while holding bulb I got dual purple snakes spinning around the tube, at higher freqs also , not so easy to replicate . I think it has some thing to do with holding the bulb and touching ground wire , where i get a " plasma ball " effect. Now for freaky part, I was stepping on the neg wire connection to the tube where it was alligator clipped on the floor and all of a sudden the tv freaks out and I get a purple, I mean PURPLE glow like I've never seen! darker than the violet ray machine . I realized I created a spark gap and got a ozone emem3 setup, very healing but i think I blew the trsnsistor. My question is this setup practical will transistors hold up? should I insert a spark plug? or just stick to the blue plasma glow setup? thanx, av77794928@...

Guest guest Posted January 1, 2002 Report Share Posted January 1, 2002 How important is the " base current " to final voltage at the tube? Now that I've done two " poorman's " that work, I'll have to admit I have had to make allowances for differences I'm sure I do not understand. Low pc output voltage: NO resistor; both pc speaker wires needed small capacitors in order to fire the tube. Regular pc about 5 volts: still no resistor, no need for capacitors on Emitter or Base from pc and fires the tube fine. Output from second unit really is much better than the first (tho the first unit works OK...puppy poo; dead worms) So, my impression is that the individual pc voltage info is necessary in order to calculate the resistor. (Way beyond me) Also, how much better than the 2n6059 is the MOSFET (there are half a dozen catalogued; which one would be most suitable assuming more than one auto coil from unknown sources in // I really appreciate all this help and helpful commentary from which one can pick up bits of info.
