Make raspberry pi board into alarm clock

My project was to make a raspberry pi 3+ board into an alarm clock over a home network using an Intel computer running fatdog linux computer to give the commands.

Instructions : I connected cheap USB powered speakers to my raspberry pi for sound. The power for the speakers
had to come from a wall adapter because raspberry pi doesn't have enough power.

Installed mx linux on raspberry pi --->
because it has bluetooth installed as default -- very easy to set up.
Not that bluetooth has anything to do with shalarm

Download shalarm
https://github.com/jahendrie/shalarm
I installed sdhalarm --> It just requires the 'make' command in the terminal
I changed the alarm sound to be more distinct
using config file --> $HOME/.config/shalarm/shalarm.cfg or /etc/shalarm.cfg
______________________________________________________________

There is raspi config app that is useful in setting up ssh to launch automatically at boot time.
_______________________________________________________
From my fatdog linux computer --> in terminal

To start up the ssh server on the pi

# ssh -Y pi@192.168.1.110
pi@192.168.1.110's password:
Linux raspberrypi 5.10.11-v7+ #1399 SMP Thu Jan 28 12:06:05 GMT 2021 armv7l

Here are instructions for running shalarm

pi@raspberrypi:~ $ shalarm --help
Usage: shalarm TIME

TIME is a 24-hr formatted time string.
For example, ten PM may be formatted as follows:

22:00:00
22:00
22
22.00.00
2200
220000

As an aside, formatting it as '10:00' will get you ten AM, and
'10 pm' won't work.

Arguments:
-h or --help: Print this help screen
-v or --version: Print version and author info
-t or --test: Test alarm set to 5 seconds in the future
-d or --debug: Check out what's going wrong (or right)
--snooze N: Enable snooze, set interval to N seconds
--timeout N: Enable timeout, set limit to N seconds

Here is typical usage....
A short alarm at 1:30 pm

pi@raspberrypi:~ $ shalarm --timeout 7 1320

Alarm is ACTIVE and set to 13:20:00
45s left to sleep

(Alarm timeout: 7 seconds)
Use CTRL-C to quit

WAKE UP!
Alarm timeout reached (7 seconds)
Exiting

Unusual things about mx linux

-No Xdialog install
-gtkdialog scripts need to use bash shell rather than sh
Therefore just change first line of script.

I'll send you an alarm clock that just needs an AA battery if you send me your raspberry pi in exchange.

Does it adjust for Daylight Savings time?
When that goes into affect in a few hours.
Will it change into a PI 4?

I am with you!
You did it because you can

I'll send you an alarm clock that just needs an AA battery if you send me your raspberry pi in exchange.

The world's most expensive alarm clock, however I like using it because it's simple to set up and I have given it a loud ringtone.
I have it always connected to my network.

But playing music using bluetooth is what it's best at.

Good its also doing the bluetooth music bit. Anyway, truth is I once used an old BBC computer for nothing much more than a sophisticated alarm clock many years back... so I'm not actually criticising the usage. I was prouder with the rotating cube I got the BBC to draw on an old oscilloscope - daft thing about that was that the code for the rotating cube was all in 6502 cpu assembly language. I used the same algorithm for various much smaller micro-controller type boards (Z80 being the first cpu I wrote it for) - so used whole computer just to digital to analog convert (for inputs to the oscilloscope) just via 3 (binary-weighted) resistors (as the simplest ever three-bit DAC).

I was able to get OSMO to work on mx linux (raspberry pi)

Method :

I get deb packages from official raspbian repository
http://archive.raspbian.org/raspbian/

and download them and open them up in fatdog linux

In mx linux I use command in terminal..

sudo thunar

to get a filemanager that can drag files into /usr/bin/

Also got mpscan compiled...
It can find addresses on network quickly.

I was able to get Xdialog to work on mxlinux by grabbing the version out of micko's repository

https://distro.ibiblio.org/puppylinux/a ... l_rb81.pet

Permissions are important. I have to superuser to change /usr/bin/
