[vcf-midatlantic] OT: Pi RCA conversion

[Evan Koblentz]

I'm reading this: 
https://www.modmypi.com/blog/how-to-add-an-rca-tv-connector-to-a-raspberry-pi-zero

I cut one end off a generic yellow-tipped RCA wire and stripped back the 
insulation.

Insider there's one insulated wire (yellow) and one bare copper wire.

Which is the positive/negative?

Rest assured, I'm experimenting on my own Pi, not the museum's. :)
