[Elecraft] Uses for K1 MCU?

[Jack Brindle]

I love it. I have quite a few PICs of various types since I do a lot  
of designing with them. Yet I, too, have a small collection of the  
programmed microcontrollers that were upgraded. Why? Dunno...

But, if you cut off the legs (and file the stubs down), and drill a  
small hole in one corner for a small hook, you can then use them as  
Christmas tree ornaments. My YF (KB4TGE) even has a pair of ear rings  
made from gold ceramic LM107s that I scrounged many years ago.

So those old chips _do_ have a use. You just need to repurpose them!
