Morse Beacon Star-Trail Lightpainting

Build a small LED Morse beacon and place it in the foreground during long-exposure star-trail sessions so the blinking pattern writes a callsign into the lightpainting while the sky stacks behind it.

The Beacon That Spelled My Name to Polaris

A dah is three dits, a letter gap is three dits, and somehow that led to teaching an LED to spell my callsign while Polaris rotated overhead.
