Same core electronics, smallest build โ a single LED strip. Total: ~$25 (estimated, + shipping, PCB, printed parts).
The core circuit and every electronic component below are exactly the same as the other models. Orlin is the smallest, easiest build: instead of separate glyph/chevron/horizon strips, everything runs off a single 55-LED strip (SINGLE_STRIP firmware capability) โ one data pin, one 5V injection point, two GPIO freed up.

* The LED strip price is pro-rated from Pegasus's 3-strip listing (55/116 LEDs of $8.96) โ the exact cost depends on the reel length you pick when ordering.
One continuous strip covers both zones โ no separate horizon or glyph strip:
Buy at least 55 LEDs and trim any further excess during assembly to fit your printed parts.
