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.
