I am in process of building a plasma generator. I will use this to recharge my ray rifle/pistol. Here is a link to what has given me the impetus for my own design. Pic's of my little beasty when it gets a little farther along, it' a pile of pieces and a gleam in my eye right now !
This was created by a friend of mine, it was his first attempt to Steampunk his artwork. CMD  |

Hey K-9 You set the bar pretty high! You know how I am about building things, I may not be good but I am slow ! Mine will be on the workbench for quite sometime yet. Check out the raygun thread. CMD  |

im glad you think im beyond that but as catmandoo said its my first piece so im happy you guys think so its gives me more motivation to make more |

Great device, I'm reminded of the 'condensers' in the movie 'This Island Earth', but as a Victorian prototype!

Here are the humble beginnings of my plasma generator. I finally amassed enough parts to begin assy. The large copper tube still has to be cut and the blade switch is not quite complete. This is not all the bits, some still need to be collected and/or created. This will give a general idea of what is needed to start with though. More pics as construction continues. CMD |

That is... scary. Very nice - especially when I realize how BIG that thing is.
Looking forward to the finished prod.
Well done.
Cheers!

That's sweet! I wanna know what the light source is.
And you're right, Her Doctor, it looks like a critical part to any child's Home Iterociter Project.

Ok, the light is a 250 watt metal halide bulb and the transformer is a 3000 volt (3K) neon sign transformer. Here is a pic of the rivet placement. Graph paper makes layout pretty simple. These rivets will be a functional part, actually holding the caps on. I put a soda can in for size reference, it's not my favorite beverage, just happened to by handy. CMD  |

I am impressed! I especially love the jellybean effect you are getting thru the mercury vapour envelope. One think you may like to try is using an alternative power source such as an RF generator as by varying the frequencey you shuold be able to get some diferent effects. It would not be as bright but would allow you to comfortably look at it.
using RF would also allow you to opperate it on DC and make the unit translugable

Thank you for the kind words Prof. Galvin, I shall take the RF generator under consideration for the next model. This one will be the base model, the next can have the Corinthian leather and the fancy wheel covers ! I still have to undertake the construction of the business end of the deal, the weapon. May have to call in a consultant for that (wink wink, nudge nudge). CMD |

Whoa. That's pretty slick. This'll probably be something I'll be making for myself. Definitely a good thing to use my years of being an apprentice electrician on. Actually, if it wasn't for the fact that they had started needing a person to get an apprentice license first over here, I'd be trying to get my Journeyman's electrician license by now.

Well, I had an issue with threading some brass rod, 1/4x28 tpi. It appears that brass reacts to being threaded very differently than steel. I consulted the machinist at work and found out that using the wrong oil is worse than none at all. Starting even slightly off square rapidly goes down hill. My solution was to bolt the drill vise to the drill press table, chuck the rod up in the collet and place the die flat on the vise body and secure with the jaws. I was able to fine tune the feed into the die, I ran it all the way by hand . I also used real cutting oil. That issue is now handled. I just made new brass rods tonight, will pretty them up in the lathe Friday and thread them at the house. Pic's to follow. CMD |

@ Prof. Galvin, How did you boost the voltage up to the required 50k ? The buck/ boost drivers that I am familiar with work with a few volts boost at best. The boost is dependent on the load and the Ma's are adjustable, all below one amp. I am most impressed that you are able to do that in the size factor required for a handheld host. CMD |

Here is a quickie to let you all know that I am not asleep at the wheel. I am in need of visiting the local metal and fitting monger (Ace) before I get to far ahead of my self. I need some more copper tube and 90 degree fittings, plumb up the large copper tubes to the internal workings. The aluminum rings will be supported by copper standoffs, 1 inch tube with ceramic insulators on each end. I am off like a herd of turtles and will report back as time and progress permit. CMD |

The boost is dependent on the load and the Ma's are adjustable, all below one amp. I am most impressed that you are able to do that in the size factor required for a handheld host. CMD Well, if you'd stop trying to apply modern electronics to a period problem, it would be easier You're looking for a Ruhmkorff coil. The modern way to do it is with a coil that is conceptually similar, but switched using solid state switches at a much higher frequency. The high frequency makes the coil proportionally smaller. Take any of those boost converter data sheets, find the "flyback converter" diagram, and replace the transformer with one that has a 200:1 or higher step-up ratio. Then watch as that lovely Victorian relay takes its revenge by obliterating your ultra-rugged power mosfet. Then spend a great deal of time and energy figuring out how to wind a low leakage inductance transformer and build a snubber circuit anyway. Eventually you should be able to get a few kilovolts or even tens of kilovolts out. For a somewhat more sophisticated approach that will scale better, look for a circuit called a Royer converter. They're used to supply the bias voltage for cold cathode fluorescents in consumer electronics (laptops, etc); they can produce 3-5 kV with high efficiency and clean output characteristics. I'm afraid I have yet to find a really good explanation of the circuit operation, though. Also, for general purpose switching converters, I highly recommend Linear Technology parts. They're not the cheapest, and they may not be the best. What they do have, though, is invaluable to the hobbyist: the best data sheets. They consistently explain, in detail, the theory of operation behind the part, and give multiple examples of how to put it to use. They don't expect you to already know everything about how to use the part before you pick up the data sheet. You can find example circuits Royer converters and other high voltage output converters buried in their data sheets. |
