The usecase is easily explained, some of us need to wake up at certain times. This is a very old problem, the first solutions were these mechanical clocks that one had to wind up manually and which made these loud ticking noises. Unbelievable nowadays, nobody in the stress plaqued modern society would be able to find any sleep with this loud clocks in the same room, we need silence.
Than we had radio alarm clocks,
the improved versions were able to retrieve a time signal from some
atomic clock, which helped when you needed to unplug them. The reception
was bad, specially in winter times, this drove us crazy sometimes. This
devices are usually resting in the closet now, dont they.
not use them any more because now we have smart phones. Typicaclly its
laying right next to your bed and you use one of the included default
alarm tunes to wake you up. Some might be using some kind of radio alarm
app, like I did.
I have never been very happy with this
solutiom, I like to go offline when I sleep because I dont wont to be
bothered. If you do this, the radio alarm will not work of course. Its
also nice to have a clock somehwere in the room so you dont have to grab
your phone to see the time. This feature got lost with the death of the
mechanical clock and the radio alarm.
So I thought, why not
recycle one of the old smartphones and tablet pc's that are starting to
pile up at home. You do not really need an app nowadays because a
website will do. They can show the time and they can start a audio
stream at a certain time, at least on some browsers
You see the result at https://meixnerit.com/radioalarm/.
The best feature is: you can remote control the radio alarm. You can
set the alarm time, and start / stop the audio stream from a second
device, for example by using the smartphone next to you.
