My second Covid lockdown has been gracious in allowing me the time to write-up one of my latest projects. How generous of it. It’s a revamp of a 1970s radio receiver into a contemporary internet web radio. I’ve documented as much as possible. Hopefully giving some ideas to anyone wanting to undertake a similar venture.
A couple of years ago whilst visiting the Maker Faire here in Paris, I stumbled upon a project of a household vintage receiver which had been revived into an internet wifi radio. Alexandre Svetec had found a faulty 70s Grundig RTV500Pi in his loft and had decided to give it a new lease of life by way of the internet. As we chatted, I was intrigued at how he had aimed to keep the main functions of the radio very close to the original. Paying particular attention to details such as a working S-meter and having the sound of white noise whilst tuning between internet radio stations, made it indistinguishable from a traditional RF radio. This was accomplished with a handful of electronic components coupled to a Raspberry Pi and some smart coding skills. The devil’s in the detail.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
