Lantern Radio

Thirteen stations. No files. Forever.

A desk radio that composes every note it plays, from the clock, with no internet and no AI.

Thirteen stations, on one dial.

Each with its own instruments, tempo and light. Scroll to tune.

Architecture

Seven layers. One block.

A machined front with the speaker's perforation, a round window, a full-range driver, one carrier board, a computer, a tap-to-mint disc and a solid back. Nothing is glued. Everything can be repaired.

Computer

A quad-core composer.

Raspberry Pi Zero 2 W runs the same composer code that lives on chain. It writes the music as it plays: harmony, melody, instruments, reverb, in real time.

Display

A round window.

A 1.28-inch round display shows the station, the piece and a visualizer that follows every note and beat. No bezel, no logo.

Sound

Small box. Room-filling sound.

A digital I²S amplifier drives a 50 mm full-range speaker placed right behind the densest part of the perforation, so every pattern breathes.

Carrier board

Keeps time without the internet.

A temperature-compensated clock with its own coin cell keeps every unit on the same second as the world. Unplug it for a year; it still knows what to play.

Mint

Hold. Tap. Yours.

Hold the + disc, then tap your phone on it. An NFC tag hands the piece to your own wallet, signed by the unit's secure chip. The radio holds no keys that can spend.

Enclosure

Drawn by its own token.

One block of aluminium, machined from solid and finished in white. Its perforation is generated from the unit's token hash, so each of the 250 is different, and ships with its score.
