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.

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.

Soul in an Old Telescope

I like this telescope.  The owner built it in 7th grade and is still using it at age 70.  I'm still using the Drake 2-B that I bought with newspaper route money, so understand the sentiments.

Soul in the Old Machine: HW-101 Saved From Workshop Cannabilism

Most of our correspondents did not like the idea of me trying to convert my Heath HW-101 into a BITX-101.  But, thinking that I still might to this,  I decided to take the old rig off the shelf and see what it looked like.  I liked the looks of it -- lots of space, simple circuitry,  nice belts and gears for turning the many variable capacitors, no black box ICs.  I could see traces of my earlier repair adventures -- electrolytic caps that had been replaced, the plastic dial clutch that I'd "fabricated" myself.  Then I decided to try to fire it up. Hey, the receiver sounded very good.  Next thing you know, I was getting the transmitter going.  Then I was working DX on 20.  By the end of the afternoon, I knew there was no way I would be tearing this old rig apart.  There is simply too much soul in this old machine. 

More on this in SolderSmoke 154....
