DJI has introduced SDR Transmission II, a wireless video system for professional productions that transmits 4K 60 fps HDR footage at 50Mbps over distances up to 2.5 miles, doubling the bitrate and extending range compared to its predecessor. The system allows one transmitter to link with up to eight receivers, and larger setups can scale to five transmitters and 40 receivers for complex multi-camera shoots.
Researchers examined the physics of toilet flushing and found that the aerosol plume generated can rise rapidly and disperse droplets to roughly face height within seconds. They identified specific factors, including flush design and water pressure, that increase how far and how high these microbial-laden particles travel.
A 2017 explainer describes impedance matching, the engineering technique of adding a component to help a system absorb energy more efficiently rather than reflecting it. It illustrates the concept with examples ranging from car transmissions and electrical transformers to sloped beaches and anechoic foam spikes.
An essay examines how Japanese woodblock printmakers since the 1880s have depicted telegraph and power lines as symbols of modernity rather than eyesores, contrasting this with Western social media users who frequently mock utility wires as ugly. It highlights a 2021 Nerima Art Museum exhibition, curated by Yosuke Kato, that gathered roughly 130 works from the 1850s to today under the title 'Densen Kaiga' (Electric Wire Paintings), showing wires as a recurring visual motif in Japanese art and anime.
Transmission continues to offer a minimal, ad-free BitTorrent client with support for magnet links, DHT, PEX, encrypted connections, and a built-in web interface for remote management. It also allows users to schedule downloads and set speed limits, making it suitable for older machines, NAS devices, and always-on servers.
