Do you do any simple experiments? Or track things and analyse them? (lemmy.sdf.org)

Recently downloaded the phyphox from F-Droid and thought about this while thinking about what all stuff I could do with it.

Are there any online resources about such stuff?

What all things have you(or people you know, in your locality etc) done along that line?
And not only big thigs, if you're tracking other stuff, please do share your experience on that too.

Edit:
Sharing the github page of the app too:

Elaborate on the ultrasound please

Of course!

I wanted to test whether a cheap piezo buzzer could be used as a crude ultrasound probe. It worked, so I tried to upgrade it into full-blown ultrasound imaging. The third iteration of that did produce an image, using a piezo buzzer cut in sections, a cheap FPGA, a MCU, custom PCB and mostly 3D printed pieces (acoustic lens, etc.). Aside from the expected low resolution, turned out that it wouldn't image anything beyond about 1 cm.

I did make a fourth iteration of the device, much smaller and theoretically much better. But life happened and I never finished the coding part.
