Re: Paper Cables?

An adventurous trial indeed! Please tell us how it sound in case you have any follow-up experiment in future when you hook up in your systems.
Sure. Though how it may sound to me won't necessarily tell you how it'll sound to you. No substituting for one's own experience.
My concerns are that paper may easily absorb moisture especially in a high humidity enviroment and may cause 'short'.
Ok, let's test that with a worse than worst case scenario.
I took a strip of kraft paper about 1/4" wide and 1/2" long. I soaked it for 5 minutes in a brine solution made using 1 tablespoon of salt dissolved in 6 tablespoons of water.
I took a 5 volt power supply and with a 100 ohm series resistor, used the strip of soaked kraft paper to complete the circuit using aligator clips at each end of the strip with their tips about 1/4" apart.
I turned on the supply and measured 0.08 volts across the 100 ohm resistor. That comes to 0.0008 amps of current. The voltage drop across the paper would then be 5 - 0.08 or 4.92 volts, giving the strip an equivalent resistance of 4.92/0.0008 or 6,150 ohms.
So, I don't think that'll be a problem.
Also if the paper cables touch any metal (because they are bare and no shielding), it may also cause problem.
Yes. Hence my warnings in my original post.
Anyways, it is fun to do your experiment!
Thanks. Now all I have to do is finish getting a new system up and running. :)
