| I've built a bunch of things: A snapcast client, which can play audio synchronized on multiple rooms https://github.com/DavidVentura/esp-snapcast An stratum-1 NTP _server_ (read: gets its time from GPS), and displays time with unreasonable precision (not necessarily accuracy!) https://github.com/DavidVentura/esp-ntp A few HUB75 signs which display public transport status (the public transport bits are not published anywhere yet) https://github.com/DavidVentura/hub75-esp An "on-air" sign that turns on/off if my wife or I join a meeting (based on camera/mic usage, for Linux and Mac) https://github.com/DavidVentura/on-air A purely decorative sign that looks like a pixelated fire https://github.com/DavidVentura/matrix-fire A kindle-controlled bedside lamp (just mqtt, but functionality is priceless - blogpost is unrelated but it's the only video I've got) https://blog.davidv.dev/building-an-mqtt-client-for-the-kind... An HDMI switcher (just a GPIO toggle) & a full-house blinds controller (just a relay hooked to the central, manual system) https://blog.davidv.dev/extending-the-capabilities-of-dumb-d... |
Is the esp board connected to a relay which toggles a regular 110V sign? I’m conflicted about running the board on a higher amperage 5V power supply and using a 5V LED matrix for indicating on-air status or just getting some off the shelf 110V type thing to toggle on or off. The matrix sounds more fun, for sure.
Edit: and thank you for sharing your work on this!
