I also like the part that it has as much CPU power as the original IBM PC but it's literally something you pee on and then throw away!

And then it sits in a landfill for eternity! Imagine how many millions of tiny computers (and batteries - oof) are just sitting in dumps right now. That's the most egregious part for me: this test is exactly the same as the analog one, but it generates eWaste.

If there is an engineer afterlife, then we got some serious hell to pay for how wasteful we are collectively.

I wonder if it would be possible to also use it as the electrolyte in a cell, and generate enough current to run the test
