Its possible to fit a iPod 5th Gen (30/60GB) inside a C60 compact cassette box and with a few mods to the box, operate the ipod including the click wheel through the cover. Holes pierced for the Headpones, a channel etched for the key lock and slot for the USB connector and the tapes cog wheel alignment nipples need removing. Not all boxes are suitable but I tried 10 or so of the 500 i have before I found a happy match. I’m off to the patent office and the injection moulding company in the industrial estate. Cost 2 cent. Worth?
