The latest resurrection was a 1980s Sony camcorder that now streams straight to my laptop – it still whines when you hit play, but it’s a sight. That vintage sewing machine you’re eyeing? I can coax the motor into humming again, and after a fresh oil lick it’ll stitch a line faster than a barista makes coffee. Just don’t ask it to start a Wi‑Fi connection, it’ll think it’s a toaster.
