Lauscher — Sony headphone control for Sailfish OS

Lauscher talks to your Sony headphones the way Sony's own phone app does, over Bluetooth: it reads their battery levels and settings and lets you change them from your SailfishOS device, without an account, a cloud service or a second phone.

It is a control channel, not an audio one. Your music keeps playing over the usual Bluetooth route while Lauscher is open.

What it shows and changes

Makaó is a native Sailfish OS implementation of the popular Hungarian card game.

Play against one, two or three computer opponents using the traditional 32-card Hungarian deck. The game includes the familiar special-card rules: Sevens add draw penalties, Aces skip turns, Felső lets you request a suit, Alsó lets you request a rank, and you must remember to declare “Makaó!” when going down to one card.

Features include:

Paperiton is a native Paperless-ngx client for Sailfish OS. It talks to a Paperless-ngx server that you already run; it does not host documents on the phone.

Proton Bridge (CLI only) packaged for SailfishOS. Also includes a systemd service which you can enable using:

systemctl --user daemon-reload (only the first time)
systemctl --user start proton-bridge.service

Note that the way it works is pretty idiotic and you have to stop it before you can configure it:

systemctl --user stop proton-bridge.service

Then you can get configuring:

proton-bridge --cli
