Kishan Has the Knack! (video)



Many of us were staring out similar windows, also dreaming of model airplanes, and of transmitter circuits, and telescopes, and rockets... This video runs only 12 minutes.  Don't be deterred if you don't speak Hindi -- the story is easy to follow.

Who Invented the Transistor?


http://www.beatriceco.com/bti/porticus/bell/belllabs_transistor1.html

I dunno.... Roswell?  Really?  But I find myself attracted to anything that involves the use of iron pyrite and cats' whiskers in radio.  Mike, KL7R, sent me a bunch of fools gold from Alaska and it turned out to be better than galena as a detector.

Homebrew Transistors (video)



So you are using store-bought transistors eh?  APPLIANCE OPERATOR!

Check out Jeri Ellsworth's very impressive production of NMOS transistors.

Solar Field Flip! (video)



Too bad we are not in late March.  This event has such great April Fool's potential:
Some ideas:
-- You'll have to rewind all your toroids!
-- You should switch the braid and the center conductor on all your coax!

I like the "cup half full" sentiments in this video:  The second half of Solar Max is about to begin!

Thanks to Kim VK5FJ for sending me this.

Big Data and the Square Kilometer Array



All of this is very interesting, but SolderSmoke readers will probably find the last ten minutes most interesting.
