Layer synchronized time-lapse using a cell phone

I use an old cell phone running Open Camera to monitor prints. Open Camera has a built in intervalometer function. As the pictures are snapped at specified time intervals, Google Photos backs the images up to the web, as soon as they are snapped, where I can view them to check print progress. After the print is done, I can use the image sequence to make a conventional time lapse video.
I have a new technique that snaps the pictures at each layer change, after the extruder has been moved away from the print. It uses a bluetooth camera shutter button to trigger the camera. All I do is mount the bluetooth button on the printer where the button will get bumped whenever I send the extruder to Y=150 using custom gcode that runs after every layer change.
Here's a sample: layer synchronized time lapse on UMMD
I need to tweak the extruder retract/unretract a bit to fix the blobbing that occurs at the start of new layers, but the trigger mechanism seems to be working reliably.

This whole topic reminds me of the PERL motto: TIMTOWTDI (tim-tau-dee) (There Is More Than One Way To Do It).
