We ran our first test piece early because we were at a stage where we needed more cables from viewers -- we got some! With the help of our audience sending in a few failed cables, we were able to reach 3 firm conclusions (or, really, 2 1) of causes for failures of these adapter cables (and unadapted ones, too).

Between foreign object debris in manufacturing (seems uncommon, but a cause) and user error, we were able to make a few cables melt.
