Radio How You Want It

A wireless, Internet-connected tuner that streams only music you’re sure to like

The options for streaming music over the Internet have increased so dramatically lately that I’ve found my FM radio has become totally irrelevant. Still, I like to be able to listen to a lot of different types of music throughout the day, and I love radios too much to give up on them completely. Now that several music services, such as, have released their programming interfaces to the public, I decided to build a custom Wi-Fi radio that can stream my favorite stations and ensure that I’ll always hear music I like.

I based my design on a radio made by Jeff Keyzer, who runs the DIY website, in 2008. The core components remain almost the same: a Wi-Fi router that has USB ports and runs the free OpenWRT operating system for embedded devices makes the perfect small, low-power brain for the radio. I opted to use an arduino microcontroller in my version as the interface between the router and the front-panel display and controls, which will make it easier for you to customize. I set my version up to play regular Internet radio stations, music from the library on a connected USB drive, and stations and recommendations. A Web interface I programmed for the radio makes configuring all of your channels a breeze. The ability to add all those extra functions and choose whatever look you want (I built mine into a ’50s-era enclosure from a surplus store)sets the radio apart from any off-the-shelf model you’ll find.

  • Take apart a router and install OpenWRT.
  • Configure the OpenWRT installation, download required packages, and install the Wi-Fi radio software.
  • Build the interface hardware. Connect the display and rotary encoder to the Arduino, and the Arduino to the router’s serial port.
  • Build the intermediary circuit board with the rest of the support circuitry, such as the voltage regulator and switch debounce.
  • Build the amplifier kit, connect the speakers, and hook up the USB audio adapter.
  • Install the power supply, and wire the power connections.
  • Configure your account and your Internet radio stations via the Web interface.
