I would like to retro-fit my 1970's pioneer turntable to be able to record onto a iPod or other USB device.

Operation

Plug in USB stick or iPod
Press record-pause
Place stylus on a chosen track
Signal level threshold trigger changes to record when the stylus hits the record
Sound file is written onto the device
Signal level threshold trigger stops recording after a few seconds pause (manual pause provided also)

No real operating system required
Program to modify iPod's XML playlist file to add the newly created track to the playlist
