A file transfer setup using no internet, Bluetooth, or USB drive. The sender converts the file into encoded QR code frames displayed rapidly on screen. The receiver scans those frames continuously with its camera and reconstructs the original file. The camera is the only communication bridge. Works entirely offline particularly relevant for air-gapped systems where network transfer isn't an option.

Bitcoin is for everyone (including $10 feature phones) 🌍⚡️ We sat down with Shishir Gupta, MD of Sorted, to talk about bringing bitcoin to the devices billions already use every day. For many, financial access is still broken. Remittances drain income as sending money to family means fees, delays, and middlemen. And while the world obsesses over shiny new apps on their latest iPhones, there’s over a billion people still using feature phones and low-powered smartphones. So Sorted decided to flip the script. They’re on a mission to bring bitcoin to one billion feature phones. Helping sats move as easy as sending a text. No speculation. No hype. Just real tools solving real problems. And the proof is already here: 250k+ downloads and backing from . And with Breez’s support they’re pushing the mission further. Feature phones don’t have the power, storage, or hardware to run Lightning. The Breez SDK changes this. No channels. No liquidity. No setup fees. Just bitcoin that works, even on the most limited devices. Leaving Sorted free to do what they do best: build for everyday adoption. Here’s Shishir Gupta's story 🎧

Wifi signals can be used to see your body through walls. Using open source software and some cheap hardware, you can measure the disturbances in wifi waves emanating from a router. Those disturbances are measured and converted into body shapes to tell you where someone is in a room.

🇺🇸 SCI-FI ON A ROOFTOP: NYC MAKES FUEL FROM THIN AIR A new machine in Midtown captures CO₂ from the air and converts it into high-octane gasoline for cars. It’s still in the early stages, but scaling it could slash carbon emissions and fight climate change. The process pulls in air, isolates CO₂ and hydrogen, then transforms them into methanol and finally fuel. Source: @aircela_official, @here_in_ny
