Move files between devices with a screen and a camera — offline optical transfer of RVF cognitive containers and WASM artifacts over animated QR codes. Mobile-first, no network, no accounts, SHA-256 verified.
Short-reach Optical Communication: A Real-world Task for Neuromorphic Hardware
Agents delivered by light: an LLM compiles a tiny program off-chip and beams it by screen-light to a radio-less Arduino that runs it forever, offline. Live at beam-claw.com
Conceptual radiation-tolerant silicon photonic inter-satellite optical transceiver with redundant primary/backup paths, radiation monitoring, GDS layout generation using gdsfactory, and first-order optical link budget analysis.
Screen-to-camera optical modem: 33 KB/s file transfer via light, adaptive OFDM with per-carrier bit loading, zero-install browser receiver
Procedural Python simulator for an 8-channel WDM-RoF link over C+L bands for 5G fronthaul — models BER, Q-factor, SNR, capacity, and throughput across fiber lengths and bit rates without needing OptiSystem/VPI.
Offline file transfer over animated QR codes — from a computer screen to a phone camera
Closed-loop educational lab for low-contrast optical QR signaling and offline reconstruction
Air-gapped optical file transfer via screen-to-camera color modulation. Implements rateless Fountain codes (Luby Transform), real-time homography rectification, and zero-copy Web Worker CV in pure TypeScript.
Air-gapped file transfer over light — a file crosses as an animated cell grid on a screen, read by a camera. No network, no Bluetooth, no pairing. Not QR.
Simulation of secret key rate for satellite based, phase matched quantum key distribution under realistic noise and channel conditions.
Adaptive star-centroiding algorithm selection and stress-test benchmark under simulated spaceborne noise.
Send data screen-to-camera as a fountain of animated QR codes. An offline-first PWA optical channel — ECDH-encrypted, systematic-fountain-coded — that works between any two screens with no network and nothing to pair. Pluggable transmission approaches you can race for speed.
PrismShare Code: an open colour 2D barcode specification
LightLink — phone-to-phone optical communication via screen flash and camera. JavaScript web app for offline device-to-device data transfer
A WDM (Wavelength Division Multiplexing) based optical communication link simulator. Change parameters interactively and analyse the outputs in real time.
Send a file from one screen to another device's camera. No network, no pairing, no install. 229.7 KB/s hand-held, bit-exact.
光だけでファイルを渡す。ネットワークもペアリングも不要な画面→カメラのファイル転送 (Fountain code + 独自コード形式)
