Open Seas
by @luupilotti.bsky.social
Discussions on open charts, plotter, and navigation on boats and the sea. OpenCPN, OpenPlotter, OpenSeaMap, HatLabs and related NMEA and AIS topics. Basically, Free Open Source Software FOSS for maritime use. Both HW and SW topics.
Every charted light on the Oregon and Washington coast, each showing its own color and flash pattern, from Cape Blanco to Puget Sound and up the Columbia and Snake to Lewiston, Idaho. 164 lights. Data: OpenSeaMap / OSM, NOAA charts, USCG Light List.
New update to my #Retrotink 4k esp32 project. Web performance for the OSD is significantly better. Little demo here showing off the navigation. github.com/v1605/retrot...
⚡ Something grey and serious over El Prat Boeing P-8 Poseidon Maritime patrol and anti-submarine warfare aircraft No timetable, no booking site, no explanation. Tracking N/A [ae68a3] at 28000ft, 202.2kt. No radar, no subscription — just a Raspberry Pi and a good view #p8 #poseidon #boeing
India's lighthouses reach more than 1,300 km out to sea, from the peninsula out to the Lakshadweep atolls and the Andaman & Nicobar Islands. Every point is a real navigational light on its charted character. #lighthouses #India #maps Data: OpenSeaMap + NGA List of Lights
The California coast by its lighthouses, each light on its real flash character. Alcatraz carried the first light lit on the US Pacific coast, in 1854; past the Golden Gate the Farallones warn ships off the rocks. Data: OpenSeaMap / OpenStreetMap + NOAA ENC
The whole Australian coast by its lighthouses, from the Barrier Reef to Tasmania to the remote WA shore, each light on its real flash character. Cape Leeuwin marks where two oceans meet; Maatsuyker Island, off Tasmania, is the southernmost. Data: OpenSeaMap / OpenStreetMap + NGA List of Lights
The southeast coast of Australia by its lighthouses: southern QLD, NSW and Victoria, each light on its real flash character. Cape Byron throws the longest beam; Sydney's Macquarie, lit 1818, was the country's first. Data: OpenSeaMap / OpenStreetMap + NGA List of Lights
Every lighthouse and harbor beacon on Japan's coast, each flashing the exact rhythm it keeps tonight. Rotating optics sweep, quick-flash lights blink in place, green and red mark harbor mouths. Every light sits on the coast. Data: OpenSeaMap/OpenStreetMap #Japan #lighthouse #dataviz
Off the tip of Brittany, in the Iroise Sea, lighthouses stand miles out on bare rock in the open Atlantic. Keepers called them les enfers, the hells: stranded for weeks when the sea was too rough to land a boat. La Jument, Ar-Men, Kéréon. Data: OpenSeaMap, NGA, SHOM
Every charted navigational light on the coast of New Zealand, each on its own flashing character. From Cape Reinga down to Stewart Island and out east to the Chatham Islands, so near the dateline they meet the new day first. Light data: OpenSeaMap / OpenStreetMap and the NGA List of Lights.
Eighty-three lights, each flashing on its own true cycle: every charted navigational light still burning in Michigan. No state has more, and every one marks fresh water rather than sea. Light data: OpenSeaMap / OpenStreetMap, NOAA, USCG. #michigan #greatlakes #lighthouse #maps #dataviz
Every lighthouse and harbor beacon on Taiwan's coast, each flashing the exact rhythm it keeps tonight. Rotating optics sweep, quick-flash lights blink in place, green and red mark harbor mouths. The dark spine is the mountain interior. Data: OpenSeaMap/OpenStreetMap #Taiwan #lighthouse #dataviz
This is what the next generation of engineers is building. 🤖⚙️ What looks like chaos is actually a robotics problem: 🎯 Navigation ⚡ Speed 🧠 Control systems 🔧 Mechanical engineering And this is exactly why student robotics matters. #Robotics #Engineering #STEM #FutureTech #5G #IoT #AI #Tech
Every lighthouse and harbor beacon on Italy's coast, each flashing the exact rhythm it keeps tonight. Rotating optics sweep, quick-flash lights blink in place, green and red mark harbor mouths. The dark interior is the Apennine spine. Data: OpenSeaMap/OpenStreetMap #Italy #lighthouse #dataviz
Every lighthouse and harbor beacon on Taiwan's coast, each flashing the exact rhythm it keeps tonight. Rotating optics sweep, quick-flash lights blink in place, green and red mark harbor mouths. The dark spine is the mountain interior. Data: OpenSeaMap/OpenStreetMap #Taiwan #lighthouse #dataviz
Every lighthouse on Ireland's coast, flashing the exact rhythm it keeps tonight. Rotating optics sweep, quick-flash and occulting lights blink in place, red and green mark the rocks. Seamless loop. Data: OpenSeaMap/OpenStreetMap #Ireland #lighthouse #dataviz
Trail Mate is a low-power, offline-first handheld system that provides GPS navigation and text messaging over the open Meshtastic LoRa network, enabling off-grid communication and mapping without a phone or internet connection.
You want to know, how late it is? Where you are? How fast you are moving? In what direction? All these questions can be answered by this system consisting of two pieces of hardware and a cable: #ESP32 #GNSS #Satellite #Navigation #M5STACK #CORE2 www.elrebo.de/index.php/20...
