Raspberry Pi-powered Radio 4 Appliance @Raspberry_Pi #piday #raspberrypi
Andrew Back‘s used a Raspberry Pi to build an internet radio that only receives BBC Radio 4:
Tuning controls and station presets? Why on earth would anyone want such things! As far as I’m concerned the only thing worth listening to on the wireless is Radio 4.
With the above in mind, I decided to build myself an Internet radio that is fixed on Radio 4 and which dispenses with unnecessary clutter, with the only control being for power and volume.
At a flea market earlier this year I picked up a 1950s extension speaker made by Richard Allan. Comprising of simply a cabinet, loudspeaker, step attenuator and input socket, and with plenty of spare room inside, this was ideal for converting into a Raspberry Pi-powered Internet radio.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
