Project 7 · Display (open-source hardware)
JDisplay, the times on the wall
An information screen for the synagogue, the school or the home: zmanim, Hebrew date and custom messages. Hardware, software and 3D-printing plans, all open source.
Getting started
Simple to build, simple to use
JDisplay runs on embedded Linux (Raspberry Pi or equivalent). No touch screen: everything is set from the JTime app, which connects securely to the display.
Everything will be published — schematics, software, enclosure plans — so that every community can build its own.
