Re: capacitance of homemade caps

Original poster: "Steven Steele" <sbsteele@xxxxxxxxxxxxx>

forget it. it's just something i thought i'd do if i could. I cewrtainly don't need it. I just got my MMCs today anyway. plus I think i'm just gonna start the whole darned thing over cuz it's beginning to seem like a lost cause with my curren, multilayered TC. I don't even know what i'm doing anymore! The whole thing is stressing me out so instead of trying to figure this one out on my own, i'm gonna start over with Dr. Resonance's M-20 because I know that works.
Then I don't know what the heck i'm gonna do after that.

by the way, here's some pics of my stuff, including the caps:

What exactly do you mean by "charge the caps"? If you are expecting
them to be charged up to some DC voltage forget it. A function
generator puts out LV AC. At this point it might be helpful if you
post a picture of the circuit you are trying to implement and some
photos of the equipment you are trying to build. A picture speaks
louder than partial descriptions. Again I think some basic electrical
theory would be rather helpful to you.
