This will probably be the off-topic-topic™ of the week, but we just couldn't leave it out. Sorry! 😐

74XX logic ICs should be known to almost everyone, who has ever played around with digital electronics, and dared to do some 8-bit experiments at home.

But these little thingies can be used for much more than just building your own calculating machines. How about a shortwave radio? 📻

Yep. 

Michael Wiebusch has done just that. And not only has he been successful, he has done away with coils, variable capacitors and Schottky diodes with his build.

Sounds adventurous? Here you can find all details about his project.

Something really different to satisfy your tinkering mania. Add to the positive side of things: a working radio.
