In December 1987, Tatsuo Miyajima announced his three core concepts: “Keep Changing,” “Connect with Everything,” and “Continue Forever.”
In the following year, upon receiving an invitation from the Hara Museum to participate in the Hara Annual exhibition, he developed an element to embody these concepts: a “gadget” that continuously measures time using LEDs (never displaying zero). To design it, Miyajima studied electronic circuitry on his own, and the resulting schematic drawing is presented here.
At the time, the circuit boards were manufactured at a factory in Machida, Tokyo, based on this drawing. However, due to financial constraints, all components were assembled and mounted by Miyajima himself.
