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:

This was years ago now; I did an experiment to test various AA battery chemistries in real-world conditions to determine if the price difference was worth it. This was tangentially related to amateur radio, I first got the idea from overhearing a conversation on 2 meters.

I used rechargeable Ni-MH, zinc oxide "Heavy Duty" batteries, alkalines, and lithiums to play a lot of video games on my Nintendo Wii. (the batteries in the controller) I found that the Lithum batteries performed less than twice as long as the alkaline batteries, nowhere near worth their price. The "Heavy Duty" batteries were less than half of the alkalines but that actually made them more cost effective. The Ni-MH batteries had the shortest single charge of them all, I forget what it worked out to be the break even point.

One thing I did note was the Lithium batteries were noticeably lighter than the Alkalines, so if weight is an issue they may be a viable option.
