Hello everybody .
I would like to understand if it is possible to create a bedroom alarm clock using a DVD player.
what I describe below are some of the features I thought of:
DVD player because when it reaches the end, unlike the CD, it can be restarted from the beginning automatically.
a buffer battery in the event of a temporary lack of energy to be used alongside the power supply which also supplies the loudspeakers with energy.
a small microcontroller circuit like the following:

weekly programming can be done and the transition from summer time to winter time takes place automatically because it uses an NTP server. the contact of the relay can be used to operate the start button of the DVD player. the first step is to create the audio DVD with the infinite loop but I don't know how to do it, do any of you know?

- can be done; need dvd authoring program and set there, what you want (auto-start, play file xx , loop.)
but just thinking: as wake up alarm, how long will it play ? 30 sec , 3 min , 1 hour ? i think, 1...10 minutes is realistic;
so can use CD player also, only thing: must be model, that starts play after powerup.
so add a timer and switch on cd/dvd and amp to wake up - simple test, whether you like it really , or not.
There are audio player modules that play files off memory cards or onboard memory, and can be controlled by an Arduino.

But if the year is 2022 where you are, there's probably a really good alarm app that can be installed on an obsolete smartphone or tablet. Or get a "smart speaker"; I've paid $4 to $12 for them at thrift stores. It's really easy to just ask Alexa to set an alarm. I haven't attempted to customize the alarm sound to the Really Annoying Ringtone from "Nathan Barley", but I expect it's possible.
