Life in Appliance Land

"Sexiest Radio!"   Hmmmm.

"It's the bomb."

The 3D waterfall is kind of cool.    As is the big screen on the wall.

Homebrew Your Own Remote Head (with a 3D Printer) (Video)



After I issued a luddite complaint lamenting the arrival in ham radio of appliance-like "remote heads", Ed KC8BSV pointed out that at least one guy -- Joe VE1BWV -- is HOMEBREWING his own remote head. (You must admit, this sounds really weird.) I still haven't completely got my head around this, but Joe's video (above) is really impressive.  

We're living in the future my friends!

Remote your heads!  With 3D printers!

Our Dismal Digital Future?


I'm sure some would find this device appealing -- to each his own.   But I don't like it.   It seems to mark another step down the path toward the complete appliance-ization of ham radio.  Note how the control head is looking more an more like something for your car audio system, or your cell phone.  
YUCK.  
Count me out. 
Just say NO! 
Menus are for RESTAURANTS!  
RIGS NOT RADIOS!   
HDR FOREVER!

From Cuba: "Technological Disobedience"



Necessity is indeed the mother of invention.  

This video made me think of the Jaguar DSB transceiver made in Cuba from the parts of Soviet-made television sets.  

Somehow I wish we were more technologically disobedient.

Digital Engineering vs. Analog Engineering


In  a book review Thompson makes this observation about the digital-analog divide: 

One difference might be that human beings can deal with ambiguity, and computers really can't. If you've done any Python [coding], you make the tiniest mistake, and everything stops immediately. That’s what makes it different even from other forms of engineering. When you are trying to fix a car, if you fail to tighten a bolt on one wheel as tight as it should be, the entire car doesn't stop working. But with code, an entire app, an entire website can go down from the misplacement of a single bracket. I think that's the one thing that sometimes scares writers away, because they are more accustomed to working with ambiguity.

I am definitely more accustomed to working with ambiguity. All of my rigs are filled with ambiguity.
