Circuit Core
CIRCUIT CORE belongs to the bench after midnight. Case open, soldering iron still warm, one board left to finish.
Three rings glow in a machined socket and fill as the day adds up. The battery drains in a glass vial, in plain sight.
Your pulse walks across a row of LEDs, one light at a time.
Still lit.
Close the case tomorrow.
Circuit Core is for the person who wants to see inside the case. There is as much to enjoy in an exposed board as in a polished exterior.
The workbench look puts that curiosity on your wrist. A small tribute to the pleasure of figuring things out.
