You could step that up and build a streaming device that connects to a quality stereo. Or, you could do what Redditor Krabizzwainch did and convert a vintage radio into a modern music streamer.
The reason to do so is, of course, aesthetics. A vintage radio just looks a lot cooler than anything new you can buy. In this case, Krabizzwainch gutted the original electronics almost completely. A Raspberry Pi with Volumio installed provides the music stream from Spotify. That’s connected to a set of small speakers through an inexpensive 15W + 15W amplifier from Drok that’s based on the STMicroelectronics TDA7297 chip.
Krabizzwainch reports that the setup works well, though sound quality is a bit staticy. They also plan on eventually implementing the original variable capacitor tuner to control which station is playing. But, for the time being, it’s already a cool vintage radio with modern streaming functionality. The total cost to upgrade the radio was probably under $60, so this is a project that should be affordable for most people.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
