“Circuitry is technology. Without circuitry there are no computers. But I got into circuitry to get away from computers. It’s truly weird.” That’s circuit bender and music-effects-guru Drew Blanke, aka Dr. Blankenstein, on his love of the tiny devices that enable or inhibit the flow of electricity through a machine. For him, electricity is not a means to an end, the passive power that allows you to watch every episode of “Adventure Time” or code on your laptop until dawn. No, for Blanke, electricity, along with the wires and circuits that carry it, is the instrument itself.
