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:

I track lots of things, all the time; my body composition, performance at specific tasks... As for experiments, I've done a few:

Tried to see if I could 3D print small channels and fill them with metal using electroplating (couldn't).
I also made a DIY ultrasound imaging device and tested it. Did actually produce some images, but it wouldn't penetrate very far in tissues.

Elaborate on the ultrasound please

[–] pancake@lemmygrad.ml 3 points 6 hours ago

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.

Cool.

Did you notice any trends from your tracking?
Things that others may also be find useful/intetesting?

Well, one thing I've noticed in most measures that involve mental things (mood, performance...) is that lots of things seem to be cyclical. For example, mood is often alternating (more so in my case), but productivity and burnout also tend to repeat predictably as long as the routine doesn't change.

Also, I'm maximally performant in tasks when most stable (good sleep, moderate mood, medication, no drugs...), but maximally productive when in a better mood.
