Kai's Redwood Mighty Mite with Poker-Chip Hacksaw Key


And Check out Kai's homebrew key:



Hi Pete,
 
  Thanks for your kind words.  I really enjoyed the MMM project, first analog oscillation 😊.  Your right about the homebrew key being a hacksaw blade and a few pieces of plywood.  The knob is an old poker chip.  You can adjust the spring tention by moving the blade in and out of the plywood.  Travel can be adjusted by raising and lowering the bolt under the blade.  I needed something for CW and wanted to stick to the ham maker thing.  As for me sending lefty, I do that so I can switch when the right gets tired or I need to hold ipod for video.  Thanks for what you add to soldersmoke.  73.

Ps I will send picture of key.

Hi Bill,
 
Wow –so cool! I was impressed with not only his M^3 but the homebrew key and sending with his left hand.
 
It would be nice for Kai to send us his details for the key.  It looked like a hacksaw blade sandwiched between some plywood blocks of wood and some sort of plastic tuning knob from a defunct transistor radio as the key knob. Now that is what I call homebrew –elegant and it works well!

The next time Pete and I get together on SolderSmoke, we'll talk about Arduino.

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.
