This looks like some fun on a rainy Sunday if you like to built stuff. The Radiomann Kit is a German radio set that is complete with vacuum tubes, coils, antenna, capacitors and other components, allowing you to build your own replica of the original German Radiomann. From there all kinds of fun ensues, including building your own transmitter and listening to morse code transmissions. More interesting to me is that this is a fantastic way to teach/learm the fundamentals of electronic circuits and how radios work.
