This page is a software-defined receiver pointed at nothing. The waterfall behind this panel is synthesized in a WebGL2 fragment shader — noise floor, carriers, packet bursts — and your scrollbar is the tuning dial. Everything you can read is real DOM; everything that glows is GPU.
Watch the strong signal in this band: it isn’t noise. Names survive the noise floor if you transmit them often enough.

BAND 02 · TELEMETRY · 432.40 MHz
Systems in the field
The bursty transmissions in this band look like the things I build: autonomous swarms, inventory pipelines, search infrastructure. Products running with real users while I do advisory work.
- Q20 Swarm intelligence infrastructure for autonomous drones, sensors, and vehicles.
- Lorrano Auto-generates social videos from car dealership inventory.
- CarGrid Makes dealerships discoverable across AI search engines.
BAND 03 · WIDEBAND · 433.84 MHz
Wideband noise, occasionally coherent
The broad smear here is what most technical writing looks like on a spectrum analyzer. I try to key mine narrower: production incidents, architecture decisions, and the occasional strong opinion about backends — published when there is signal, not on a schedule.

The keyed carrier in this band repeats a general call: seeking any station. If your backend is transmitting mostly errors, answer it.
