Realizing I intentionally opened a png bomb made me chuckle, like what did I think was going to happen?

Okay, that is good to know thanks for pointing that out.

The "free" federal tax filing service I use in Florida, makes their money by charging for state filings. It will add an additional hour or two of effort to every resident of the state, even if they are below the state income threshold which is quite an externality.

Also, I would be wary bragging about buying your goods in Oregon, you technically may owe WA use tax https://dor.wa.gov/taxes-rates/use-tax.

Did you consider trying the iPhone accelerometer? Perhaps lay the phone face down on the table and then lay the watch on the back? Wondering if this would have higher or lower SNR.

Not to mention, those same carbon emission regulations/targets they are lobbying/fighting against did not come about in a vacuum. The regulations were intentionally cranked up to "unachievable" levels for ICE vehicles from groups pushing other technologies.
