RE: Solar-powered calculators
Has anyone ever ginned up a solar powered HP41? I know there isn’t enough real estate on the calculator so it would mean dangling a solar cell off of it? However given it only draws a few hundredths of a milliamp when off and 10mA when running would make a fun project? Wasn’t there a power from USB module hack?
