| ryan | technology | Last Wednesday if you would have asked what I had planned for Easter I would have said something like, “Going to hide some eggs for my daughter even though she knows the Easter bunny isn’t real.” Then suddenly my wife and I were planning on entertaining for 11 family members. My how things change! Since I was going to have family over, some of whom are [Giants](https://www.mlb.com/giants) fans, I wanted to show them the [ITFDB program I have set up with my Pi](http://www.ryancheley.com/index.php/2018/02/13/itfdb/). The only problem is that they would be over at 10am and leave by 2pm while the game doesn’t start until 5:37pm (Thanks [ESPN](https://www.espn.com)). To help demonstrate the script I wrote a _demo_ script to display a message on the Pi and play the Vin Scully mp3. The Code was simple enough: from sense_hat import SenseHat import os def main(): sense = SenseHat() message = '#ITFDB!!! The Dodgers will be playing San Francisco at 5:37pm tonight!' sense.show_message(message, scroll_speed=0.05) os.system("omxplayer -b /home/pi/Documents/python_projects/itfdb/dodger_baseball.mp3") if __name__ == '__main__': main() But then the question becomes, how can I easily launch the script without [futzing](https://en.wiktionary.org/wiki/futz) with my laptop? I knew that I could run a shell script for the [Workflow app](https://workflow.is) on my iPhone with a single action, so I wrote a simple shell script python3 ~/Documents/python_projects/itfdb/demo.py Which was called `itfdb_demo.sh` And made it executable chmod u+x itfdb_demo.sh Finally, I created a WorkFlow which has only one action `Run Script over SSH` and added it to my home screen so that with a simple tap I could demo the results. The WorkFlow looks like this:  Nothing too fancy, but I was able to reliably and easily demonstrate what I had done. And it was pretty freaking cool! | 2018-04-01 | itfdb-demo | Last Wednesday if you would have asked what I had planned for Easter I would have said something like, “Going to hide some eggs for my daughter even though she knows the Easter bunny isn’t real.” Then suddenly my wife and I were planning on entertaining for 11 family … | ITFDB Demo | https://www.ryancheley.com/2018/04/01/itfdb-demo/ |
