Internet radio

RadioGlobe takes the internet radio world for a ride


There is no denying that the range and variety of internet radio is super cool. The problem is, none of the interfaces available really give the enormity of the thing the justice it deserves. We aspire to a more physical and satisfying interface for tuning to stations around the world, and [Jude] did just the right thing.

RadioGlobe allows the user to tune in to over 2000 stations from all over the world by rotating a real globe. It works by using two absolute rotary encoders which each have 1024 positions available. An encoder is stuck in the South Pole, and it is reading lines of longitude as the user spins the globe.

The other encoder is on the left side of the globe and reads the focused latitude in the reticle. Both encoders are connected to a Raspberry Pi 4, but if you want to replicate this open source project using the incredibly detailed instructions, it says a Raspberry Pi 3 B + will work as well.

In the base there is an LCD screen that displays the coordinates, city and station ID. Other stations in the region can be tuned with the dial on the base. There is also an RGB LED which flashes red while the station is tuned in and turns green when done. We totally dig into the clean, minimalist look of this build, especially the surprise see-through bottom panel that lets you see all the guts.

There are three videos after the break – a short demo that gives you the basics of how it works, a longer demo, and a nice explanation of absolute rotary encoders. These are just the tip of the iceberg, because [Jude] kept a daily vlog of the construction.

Maybe you just crave web radio that offers vintage appeal. This antique internet radio has a lot of features, but you wouldn’t know it from the outside.
