[NJARC] Fwd: Arduino 4-in-1 Counter Project

Fri Jul 15 14:11:22 EDT 2016

Hi Joe,

Arduino is a really interesting phenomenon, but it goes in a different 
direction from the 
stick-some-components-in-a-circuit-card-an-have-a-radio situation we 
were used to.  The wiring is usually pretty simple, but not as organized 
as the "put the 10K resistor BROWN-BLACK-ORANGE here" situation.  You'll 
likely have to read a schematic and count pins. All the rest is SMOP 
(simply a matter of programming).  Fortunately, most projects involve a 
pre-written "sketch" (program) that you may want to hack to get your 
desired results.

One probably ought to start on wikipedia: 
https://en.wikipedia.org/wiki/Arduino  It's interesting that Ardunio was 
the bar where these guys hung out.

What the Jameco kit has going for it is convenience, but it's rather 
overpriced.  I'd also check on the capabilities of the freq. counter.  
I'm not sure Arduino can do more than a couple MHZ without additional 
circuitry.

The last Arnuino UNO's I bought out of China via Ebay were $3.50 each 
shipped.   Inspired by Joe's email, I just ordered a couple of the LCD 
"shields" with push buttons, as seen in the Jameco kit, for 3 bucks 
each.  There are comprehensive starter kits, most including LCD display 
and even a stepping motor, in the $25-50 range. (Ebay)

The reality here in the 21st Century is that it's more cost effective to 
sell a complete item, like an Arduino board, than to try to kit up a 
bunch of parts and write assembly instructions.  The end product would 
get really expensive.

However, modern microcontrollers give us the capability to do things 
that would have been a real PITA in the old days.  Consider the 
simulated Marconi Cape Cod spark transmitter that feeds this demo:

I took deliver of an Arduino, plugged it into my PC, loaded the 
development software (free) and checked that the LED on the circuit card 
blinked.  Then I used Google to find an Arduino Morse code beacon 
sketch, that flashed Morse on the LED.  After an hour of hacking I had 
it feeding Morse as as a 240 Hz square wave (there was a built-in 
instruction for this) to a simple LC circuit to make spark-like RF,

In the late 20th Century, it would have taken me weeks to do this, even 
though I have some background in micros.  Now it's trivial.

I'll let Klancer tell you about Rasberry-Pi.  He has one grabbing AP 
news off the Internet and feeding it to a WWII teletype at the Museum.

Enough,
Al
