SolderSmoke book for $16

QST gave the book a very nice review in their August edition.  But they got the price of the paper edition wrong -- it is definitely not $45!  The normal price is $20, but with the coupon code SOCIUS you can get it for $16 through 19 July.

book review in qst? GOT IT

Thanks to those who sent me the review.   Got it. 


I heard the August qst has a review of the soldersmoke book. I'm away
from home. Could someone email me the review? Thanks 73

A Visit to the Arduino Factory (video)

Named for an Italian bar, produced by cool people in Ivrea who wield soldering irons and wear T-shirts that say "Make it Simple."  You gotta love Arduino! 

Today I will finish connecting my Arduino Uno to my Doug Demaw Lil' Slugger 10 Beacon rig.  Code (computer code!) by K6HX.

The Society for Model and Experimental Engineers

Wow.  Stop what you are doing and take a look at the four short films about a group of intrepid British knack victims.  Very nicely done.  Really captures the allure of the shack/workshop.

Arduino Sidecar (instead of a Shield)

In my last post I described my Arduino Keyer Kludge.  In that project I didn't use the standard "shield" board that normally sits atop the Arduino board.  I had used a shield in an earlier project and I didn't really like it.   I prefer to have all the electronics and connections on the top of the board -- this makes for easier experimentation and modification.  

Above you can see my "sidecar" technique.  I build the circuit on a piece of copper clad board using isolation pads superglued to the copper (aka "Manhattan style").   For the Arduino board, I just superglue a piece of balsa wood to the copper clad board, and attach the Arduino board to the balsa with small wood screws.  Electrical connections from the Arduino to the sidecar just go from the Arduino pins to the appropriate points in the sidecar circuit via small-gauge wire.

Paddle Output Arduino Keyer Kludge (video)

Ooops -- I got my keyer terminology wrong in this video.   The K1EL keyer just needs a "paddle keyer" input, not an iambic keyer.   One line is brought to ground for dots, another for dashes. (With an iambic keyer, if you make both contacts at the same time you get a string of alternating dots and dashes.)  My homebrew cootie keyer did the job, but I wasn't very proficient, hence the need for this digital kludge. I also got the name of the Arduino guru wrong: he is Massimo Banzi.  Mi dispiace Massimo.

Feynman's Red Book (on the Sino-Indian Frontier)

Today I bought a copy of "Feynman's Tips on Physics."   I wasn't sure about buying it, but this story in Ralph Leighton's foreword convinced me:  

"At a lonely border post high on the Himalayan frontier, Ramaswamy Balasubramanian peered through his binoculars at the People's Liberation Army soldiers stationed in Tibet ― who were peering through their scopes back at him. Tensions between India and China had been high for several years since 1962, when the two countries traded shots across their disputed border. The PLA soldiers, knowing they were being watched, taunted Balasubramanian and his fellow Indian soldiers by shaking, defiantly, high in the air their pocket-sized, bright-red copies of Quotations from Chairman Mao ― better known in the West as "Mao's Little Red Book."

Balasubramanian, then a conscript studying physics in his spare time, soon grew tired of these taunts. So one day, he came to his observation post prepared with a suitable rejoinder. As soon as the PLA soldiers started waving Mao's Little Red Book in the air again, he and two fellow Indian soldiers picked up and held aloft the three, big, bright-red volumes of The Feynman Lectures on Physics.

One day I received a letter from Mr. Balasubramanian.  His was among the hundreds I have received through the years describing the lasting impact Richard Feynman has had on people's lives.  After describing the "red-books" incident on the Sino-Indian Frontier, he wrote, 'Now, twenty years later, whose red books are still being read?' "
