Hi again. Another way of capturing the drops could be to place a piezoelectric knock sensor on the back side of the plate where the drops ar hitting the plate. You might even be able to connect the sensor directly to Arduino and eliminate the Schmitt trigger.
In this case adding labels wouldn't add very much. The captured data is just a one-dimentional string of numbers. I convert that one-dimentionls vector into 3D coordinates to plot like this: If the string of numbers is n1, n2, n3, n4, etc. the (x,y,z) coordinater will be (n1,n2,n3) (n2,n3,n4) (n3,n4,n5) etc.
but then, the pattern you are talking about is not a real pattern coming from the physical droplets, but something that emerges from your algorithm to classify the one dimensional data into a 3D plot
Here's the link runiter.com/graphing-calculator/ There is a free trial version, but to do anything meaningful you will need to subscribe to at least the Standard version. It's a great program and worth it to me. :)
yes im into this right now ,great minds think alike Rick ,im also into cigarbox guitar been watching your vids great work, how can i get your booklet you provided as im a lerner cheer my friend
If you register when the drips break a light beam, you might get data that does not have as much noise as the recorded audio signal.
You're right. I'll give it a try and compare the data sets. Thanks for the suggestion. :)

Another great idea! Thanks. It probably would pick up just as well as the piezoelectric strip under the bridge of my guitar.
Why don't you label the axis of your plots?

Where can I get the "Graphing Calculator 3D?

Thanks for the comment. Glad you liked the video. The CBG booklet is available as a free download (pdf) on my website. rickmckeon.com/cbglessons.html
