W9ZN's CW Warm-up: "Ben's Best Bent Feet"

I happened to come across this fellow's signal on 40 a week or so ago.  His warm up routine really had me scratching my head.   I've been on the air for a long time, much of it on CW, and I never heard anything like this.   Listen to the video (!) and you will see what I mean. Harmless fun I guess, and there does seem to be a connection to radio history. 

Pilgrim's Progress: A Peregrino Rig Concealed in a Book

On the G-QRP list guys have been talking about the Peregrino.  This is a nice little homebrew rig out of Spain.  Peregrino = Pilgrim and usually refers to people who are hiking along the Trail of Santiago that runs through the North of Spain to Santiago de Compostela.

I'm normally averse to chips, but this little rig uses two very understandable NE602s and an equally understandable LM386.  It has a homebrew crystal filter.  I like it.

GM4WZG came up with a really wonderful enclosure for his rig.  This reminded me of the time I put a QRSS transmitter inside a copy of "The DaVinci Code."

The Spanish guys have a nice site that describes the rig.  Google Translate should help, but even without it you can get most of the info you need from the schematic, chart, and foto gallery.  Check it out: http://ea3ghs.qrp.cat/peregrino.html

Enhorabuena!

Juliano Blues

Pete swears the rigs work better with this color. 

We are adding Sherwin Williams "Juliano Blue" paint to our investment mutual fund: Drake 2Bs, copies of SSDRA, QF-1 Q Multipliers and now, Juliano Blue! We'll all be RICH!

"The Radio Times"

Wonderful stuff:

Which way does current REALLY flow?

I've talked on the podcast about launching a worldwide campaign to require the reversal of ALL those little arrows on the symbols for transistors and diodes.   You see, they are saying that electricity flows from the positive to the negative.  Engineers apparently got that idea from Ben Franklin, and they are sticking with it.  It is time for a change!   Reverse the arrows!  Down with CCF!  Viva Electron Flow!  Let's tell the truth!

This morning Bob Crane W8SX sent me this very interesting article on this topic from Nuts and Volts:

http://www.nutsvolts.com/magazine/article/which-way-does-current-really-flow?utm_source=Newsletter+%2332&utm_campaign=Newsletter+%2332&utm_medium=email

The article describes very well the origins of this controversy. (There were one or two scary moments in which I thought the author was getting ready to tell us that positive ions can move through wires and transistors (NO!) but he pulled back from the brink and clarified that he was talking about ion flow in electro-chemical batteries.  Whew, that was scary!)

But here's a question for the philosophers and historians of electronics:  When physicists decided to label the electron as "negative" this was an arbitrary choice, right?   They could have just as easily decided to call it "positive" with the protons being called "negative" right?  In this case all the arrows in our diagrams would not be in need of reversal, right? 

Shotwell had the Knack (Car Knack), and so does Jay Leno

I've joked about homebrew cars -- we have a bumper sticker on Café Press that says "My Other Car Was Homebrewed From Junkbox Parts."  Well, in this video Jay Leno shows us a true homebrew car, this one built by a 17 year-old in 1931.  In the video you will hear some interesting comments from Jay on the kind of technical and mechanical skills that were expected of young men in the 1920s and 30s.  At the end of the video, watch Jay suffer the consequences of replacing a 20 amp fuse with an 8 amp fuse.  Who among us have not done something similar?   

Cool, Blue, and Homebrew! Pete Juliano's Tiny SSB Rig

Blue is the new Black!  I think some smart paint manufacturer should put a trademark on "Juliano Blue."
