Schedule alarms with a message and news, weather forecast to be read aloud with AWS Polly through Raspberry Pi
https://www.youtube.com/watch?v=CqU3jfzUy6c
This assumes you're running a LAMP stack on your Raspberry Pi and have an AWS account to use AWS Polly
- Raspberry Pi
- LAMP Stack
- Python
- Pygame
- AWS CLI - you have an AWS account such as the free tier
- create an IAM user to authenticate against AWS Polly
In the index.js file under alarm-polly/front-end/js/ be sure to set line 112 correctly regarding the curLocaleTime variable. Just search for Chicago in the code. It's default set to +5 which works for me in Central Time. Your time may be different and you'll get a false alert that says "Please select a future date". If necessary, alert the two times being compared eg. the current date time(locale) and the date time you selected on the popup date picker on line 133 eg. if (selTimeDate < curTimeDate) { under alarm-polly/front-end/js/index.js.
- Yahoo Weather API - need to provide your city and state
- News API - you need to sign up and get a key (free)
The medium post goes over most of the instructions, this assumes you're able to use a terminal/know what LAMP/python/pip/pygame/aws are.
The directory paths are:
/home/pi/alarmPolly (back end)
/var/www/html/alarm-polly (front end)
The two scripts that run alarm polly are ran by CRON every minute in sequence like this:
check scheduled alarms
* * * * * /usr/bin/php /var/www/html/alarm-polly/php/check-alarm.php && /usr/bin/python /home/pi/alarmPolly/get-articles-parse-synth.py
Even if you have a Pi Zero you can do this, provided you have some spare parts. Namely: a couple of resistors, capacitor and a film capacitor. I myself am using a Pi Zero to run this. You have to build a little filter and use the tutorial provided here by Adafruit. https://learn.adafruit.com/adding-basic-audio-ouput-to-raspberry-pi-zero/pi-zero-pwm-audio
