two pieces of spaghetti, but put one through a manicotti and you’ve got yourself a coax line, as long as your ricotta has a decent dielectric constant.
Anyone else getting hungry now? I wonder what effect a nice marinara sauce would have... On Mon, Oct 14, 2024 at 12:14 AM Herbert Johnson via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:
Somehow I'm CC'd privately in this discussion, of impedance of a DSL 6MB/s line made of wet salty starch. But I'm a BSEE engineer, so there is a theoretical answer. There's a practical answer, that's likely harder to describe.
Fifty years ago, I solved a similar problem, in showing how 9600 baud communications could be done on 250 feet of twisted pair telephone cable. PhD's said it would not work. I did not an analysis. I hooked up the wire spool between two terminals and started typing.
I don't think a wet-pasta analysis is worth bothering with. It's simply a happenstance that the DSL traffic happened to *succeed*. "The amazing thing about a dancing bear, is not how well it dances, but that it dances at all."
So enjoy the result and don't fuss about the solution.

It depends on what it’s saturated with, what kind of solution? Copper sulfate, salt, any other kind of conductive solution.

What exactly is the ohms-per-foot of wet pasta?!? :-)

The winning entry for the DSL competition involved somebody sending 6Mbps of traffic over a pair of wet spaghetti (yes, literally they used two pieces of wet pasta). -- Herbert R.
