This was an inspiring episode Kevie! It starts thoughts of when I can have use of it. 

As you said, the computer must be turned on in order to have the scheduled recording to record. It got me thinking of the Termux app for Android based phones. I have not tested, but I thinking of that it might work to get this command line recording to work on the phone.

Also the Transistor app for Android phones was interesting, I like the app after my first trials.
