Summary
- A post by hackaday.com highlights an “old-school” radio build that is not old-school at all, using modern ICs and a micro-controller.
- The dsMP3 build by Minh Danh offers a radio, MP3 player and voice recording in a single device.
- The radio receives both AM and FM frequencies, including AM bands for shortwave, medium wave and long wave, with FM support for RDS.
- It uses a TDA1308 for headphones and a NS8002 to drive stereo speakers, both feeding into a dsPIC micro-controller for button and playback control.
- The micro-controller can read MP3 files from a USB stick and write WAV files for recording radio broadcasts.
- Extensive documentation and schematics are included in the post, along with a link to the firmware design.
