    Has anyone used metal sheets/tin foil to rig up a parallel plate capacitor? I suspect i'm only going to get stupidly low orders of farads... what values did you get? I ask because i need to get a decent time constant, but there are only so many resistors i can add if capacitance is too small.

    Cheers,

    we did this in school. didnt measure capacitance though.

    you can buy capacitors very very cheaply. why not just do that

    only a flux capacitor, worked pretty well, took me to the year 3000
    sorry. i really couldnt resist....

    we've done this at school. can't remember the values but it was really low.

    Hoping to investigate some properties, varying dielectric etc. If i made a larger scale capacitor i can take my own measurements... if i buy commercial ones then i'm gona just be reading of the box. I cant seem to find data about the dimensions and materials of commercial ones either. This could be because details are trade secrets, or it could well be because of the ridiculously convoluted labeling system.
