Open School Bell

[Adam Laycock @AdamMLaycock]

Less than a week before I present @openschoolbell at @TheANME and I’m bench testing a major new feature…

Action buttons! This button is tied to lockdown, after holding for 2 seconds the light goes out and you can release. 5 seconds later it fires the action.

Out today Controller 1.4.0!

New in this version a full translation system and Polish translation by @mbrzuchalski

We've also added audio sequences to scheduled rings, so now you can mix up sounds on a ring.

Controller 1.2.0 is here!

This release is mostly QOL improvements. Mainly the ability to assign a day type to a whole range of days. (Guess who just need to apply 6 weeks of "Holiday")

Now connected is the sounder running the screen, this pi touch display 2 is hiding a relay that is wired into the ringer wire input. Notice that satisfying clunk when we trigger the old bells.

Day and a half later, 10 speakers, ~130M of cable, 1 amp and 1 Raspberry Pi we have a working school bell in the new build!

[Open School Bell @openschoolbell]

And with that the first speaker in the chain is wired up and ready to go.

Today is the day! Open School bell moves from bench testing to fitted into a building!

Here’s the start, a @Raspberry_Pi 5 connected to a 100V line amp. From here cable will be run out to speakers in every classroom and corridor.
