[hqcqephv] Mechanical typewriter

Create an unpowered device (or hand chargeable) with which a human can record data in a machine-readable form. A mechanical (not electric) typewriter qualifies, though one wonders if one can do "better" for some measure of that word: perhaps in portability. Fewer buttons? Pen and paper does not qualify, because handwriting recognition is not so good.

Inspired by World War II correspondent Ernie Pyle.
