A couple of TEA5767 Low-power FM stereo radio chips landed in my lap. They arrived mounted on a small module board with all the essential supporting circuitry, so they should be ready to run without much external hardware.
This project is a simple test drive under Arduino control.
It simply skips through a selection of local FM stations and works amazingly well!
As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub.

Ben Eater published a fantastic video/tutorial on designing a 7-segment hex decoder as an adjunct to his 8-bit breadboard computer quest.
The first thought was of course “that’s an awful lot of work just to drive a 7-segment display .. lucky we don’t have to do that these days!”
My next thought was naturally: “OK, now let’s build it!”.
It was in fact a great excuse to dust off some combinational logic methods.
