Easy fix: drive old garbage like me, lol. Or grab an old classic, throw some money at it, and you've got something cool that costs less than some new POS. My '78's clock sets with a knob.

Awesome write up. Love it. And good thing you documented it, since in half a year you'll need it again. My takeaway: You should have just gotten the SD card and trusted the previous owner. Sometimes "simple users" do know. ^^
