Re: [TCML] Microwave caps

I don't quite understand the post either.
For 90 caps with 10.5kV rating, then 18 strings with 5 per string. Results in 1.8uF, 90j. 
Using 0.5uF/2100V MO caps.

Regards,
Bart

Jim -
I don't understand your post; can you explain the math? How did you arrive at the "10kv" rating? With five series-connected caps per string? 

Joel's caps are predominently .5uF at 2,100V.

(Incidentally, the unit of energy is "joule".)

Herr Zapp

Hi Joel,

Lets see, if you series 2 (10kv) easy- .5uf*(45 caps)=22uf= 1100 Jules-
definitely a worthy ring launching, HD disk plates, or coin shrinker. Please be very careful with this as it is absolutely lethal. Be sure to discharge the caps a couple of times. The internal resistor will discharge them over 
time.

First thing: i cannot be held responsible for anything you do with your
capacitors, but here is what i did with some of mine:

As the previous poster mentioned, id highly suggest a very sturdy enclosure built to contain shrapnel and oil in the event that the weakest capacitor "lets go". Pleeeeeeeease be extremely careful with these things when you gang them up, there is some very serious energy storage. Other than that, 
MOCs seemed to work great for launching rings and other Not-So-Hard-Core
pulse power stuff. Basically the caps are junk anyway, so why not have a
little fun with them for awhile?  Just really keep safety in mind!!!

I'm pretty certain I've seen them used in coin shrinkers.May be worth a
google search if interested.If I recall though none of the projects I saw 
used anywhere near ninety caps but perhaps you'll end up with a more

robust
end result than those before you.I would imagine ring launchers and rail 
guns are also feasible.Probably wouldn't hurt to place your caps in a

sturdy

enclosure no matter what you build.Just in case! Wyatt

A while ago I posted a question about the poor performance of my coil, and through the list's help, found out that microwave oven caps don't work in 
the tank circuit.
So here's my question: What should I do with 90 MWO caps? I have heard

that

they are used in voltage doublers and filters, but is there another

project
I could use them in? I have my eye on building a Marx generator, so would 
these work for that? Or any other project you all can think of?

Thank you for your time!

 Sincerely,
Joel Torgeson
