A calm coastal instrument.
The Salt Light Instrument is a hand-built 7-inch pane of glass for the wall that quietly tracks the weather, tides, sky, surf and the ferry, and keeps showing the last good reading even when the internet doesn't.

Temperature, the day's sun arc, a two-cycle tide curve, and the next twelve hours, all at a glance.
Tonight's moon phase and an overhead map showing exactly where the sun, moon and planets sit over your deck.
Surf height and framing, swell and period, water temperature with its trend, and live shark activity near the island.
An airport-style departure board for the next boat to and from Point Judith, with the next sailing counting down.
Warm golden-brown, open grain. The lighthouse default.
Pulled from the source, the moment it changes
Live coastal feeds sync over Wi-Fi; the sun, moon, planets and tides are computed on the device itself. Everything's cached, so a dropped signal never leaves you in the dark.

The launch version of the Salt Light Instrument is tuned specifically for Block Island. Dynamically updating information for other locations is coming soon.
The public feeds above are included over Wi-Fi. Non-public or commercial data feeds require self-hosting or a subscription.
It keeps its cool when the connection doesn't.
Plenty of the coast has thin Wi-Fi. The instrument computes tides, sun and ferry times on-device, and when a feed is out of range it holds the last good reading. At dusk it dims itself; at dawn it brightens. No buttons to babble at, no notifications begging for attention.
Bring the coast indoors.
The Salt Light Instrument is hand-built to order and tuned for Block Island, ready for the wall. Join the waitlist and we'll tell you the moment it's available.
