TRS Drawbot

Old RadioShack logo as drawn by TRS Drawbot.

TRS is a double acronym for Tip-Ring-Shield (the technical name for the stereo headphone connector that controls it) and Tandy-RadioShack (the sponsor).

I designed this ultra-minimalist two-servo drawing robot to be directly controlled by a digital stereo audio signal—as from an iPod or smartphone headphone jack—for MAKE’s “Weekend Project” campaign, sponsored by RadioShack, in early 2013. In was published both online and in print.
