Hi Everyone,
I've always wanted to do this, but after some discussions about Duelunds I thought I'd try it.
I took 2 sheets of Reynolds Wrap 4 x 12" sheets of aluminum foil, separated by Glad cling wrap, and rolled around a wooden skewer. I got 6 whole nanofarads!
Stay tuned for the listening tests...... 😀 😀 : D
Best,
Erik

6nF is very small. 1000 nano = 1 pico, 1000 pico = 1 uF.
To get a 1uF you will need 1 Million times more surface area 🙂 or use thinner plastic wrap.

I think you went the wrong way. 🙂 1000 nano = 1uF. 1000pF = 1 nF
Still your point that it may in fact be more expensive per Farad than a Duelund is well taken. Now if I can make it ugly, I'm sure I'll get buyers. Each capacitor will need it's own building however, with expensive accessories to house them in and liquid mercury tubing to connect them all.
But that will have to wait until I compare Reynolds with Trader Joe's aluminum foil. 😛😛😛

Yes, my bad on the math there - you need 500x more surface area - maybe not so bad.
Great, you made a crappy mylar-alike cap with horrible DA; the saran is low-density polyethylene. Real homemade kitchen-audiophile caps will undoubtedly use waxed paper and tin foil. Or uprate to polypropylene 😉 *
Nice experiment though, something I've never got around to trying.
*for example
Clear Polypropylene Film Rolls (Flower Wrap)
(I'm joking, really, the geometry, winding tension and end connection details of even crappiest industrial caps punts what the DIYer can achieve into the long grass)

I went for Press'n Seal because it has it's own adhesive, and the winter graphics reminded me of Christmas. Maybe I should try a Disney theme next.

Not to toot my own horn here, but what a difference 270 years can make!
According to Wikipedia, the original Leyden jar built around 1745 had an entire nanofarad. I beat it by a factor of 6, and out of things my technologically backwards kitchen had lying around and which are probably only mildly carcinogenic. 🙂
