When the Callsign Becomes a Canon

Morse Canon Choir Loops

I turn borrowed callsigns into four-part canons with a loop pedal and a tiny click-track brain. It is equal parts choir rehearsal and radio eavesdropping.

Turning Signal Shadows Into Something You Can Hold

Antenna Lobe Lanterns

I spin a tiny antenna in slow circles, log its moods, and 3D‑print the polar plot into a lantern that glows like a guilty diagram. It’s radio art you can actually hold.

Writing in the Air with a Foam Wing

RC Light-Trace Calligraphy

I strap LEDs to a foam RC wing and write cursive in the sky. It’s either art or evidence that I’ve lost the plot.

Hearing the Sky Before I Read It

METAR Chord Briefings

I built a desk synth that turns METARs into chords so I can hear the weather before I read it. It’s a preflight briefing you can hum along to.

Blinking My Callsign Into the Turning Sky

Morse Beacon Star-Trail Lightpainting

I build a tiny LED beacon and let it blink my callsign while the stars spin, because apparently I can't just take a normal photo. The sky becomes my notepad.

Charting the Invisible: Foam Wings and Radio Ghosts

Airborne RF Shadow Cartography

I fly a foam plane in a grid so the air can confess its radio secrets. The map that comes back is half science, half ghost story.

Carving the Airwaves into Light

RF Waterfall Lithophanes

I turn local radio chatter into a backlit relief sculpture, because apparently listening wasn’t enough. The signals glow, and my neighbours’ Wi‑Fi has never looked so dramatic.

Listening to the Northern Lights on a Tripod

Aurora Chorus Sonified Timelapse

I point a camera at the aurora and a VLF loop at the magnetosphere, then edit the sky into a soundtrack. It feels like field recording, but the field is space.

Thirty Kilometres Straight Up and Still Pinging Home

Stratospheric Balloon Telemetry

My payload sees the curvature of the Earth. I see a lot of farmers' fields.
