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)

Systems

  • Power supply
  • Analogue phono stage (requires ±12V DC)
  • Stepdown power supply to give 5V± 3A from the main turntable transformer

Microcontroller

Features

Operating system

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