Is This The Smallest Internet Radio?

Internet radios have been a factor in some kind for the final quarter century, and the appearance of low-cost networked microcontrollers has made them simpler than ever to construct. But simply how small can one be made? [Milen] has made one which’s about as small as we’ve seen, and put it up on Instructables.

The {hardware} recipe is simple sufficient; take a microcontroller, join it to the web, and have your web radio software program squirt its output to a DAC. In this case the microcontroller is an ESP32-C£ on a really small dev board, and clipped to that may be a customized PCB with a PCM5102A I2S DAC and an amplifier. The entire factor is tiny, sufficiently small actually that the 2 connectors are important in dimension in comparison with it.

Whether or not it’s a sensible gadget for listening stays to be seen, however it’s actually tiny. But the query is, may or not it’s made smaller? Perhaps eschewing the connectors could be a straightforward win, and in return for a loss in high quality the ESP has a built-in DAC that’s not meant for audio however can be utilized. If you have got any vivid concepts, we’d have an interest to listen to them.

We’ve seen loads of web radios through the years, and for some motive this cassette-shaped one appeals to us.
