This weekend I was playing with the Arduino that I bought (supposedly) for Billy. You see, I have a little microprocessor-based keyer in my ten meter beacon rig (Demaw&#8217;s &#8220;Lil&#8217;Slugger&#8221;) . It works fine once you get the desired Morse sequence into it, but getting that done is difficult and frustrating for someone (like me) unaccustomed to an iambic keyer. So I was thinking that this would be easier just to replace the keyer with an Arduino. I was right. With some help and advice from Billy, I got the Arduino going, and got the little LED blinking. Then I took<\/strong><a href=\"http:\/\/brainwagon.org\/2009\/11\/14\/another-try-at-an-arduino-based-morse-beacon\/\"><strong> some code from Mark K6HX<\/strong><\/a><strong>, modified it for my call-sign, and loaded it into the Arduino. No problem at all. Kind of fun. And it opens your eyes to all the possible applications of this little board. <\/strong><br \/> <strong> <\/strong><br \/> <strong>Unfortunately, in the course of fooling around with the interface between the board and my rig I think I did damage to my Arduino. I managed to blow out the blinking (pin 13) LED on the board. I could live without that, but now the ICs get very hot (especially the little surface mount chip just below the 16 MHz crystal). Anyone hope of fixing this? (I&#8217;ve already ordered a replacement board, but I feel guilty about this.)<\/strong><br \/> <strong> <\/strong><br \/> <strong>Here&#8217;s a good article describing the pros and cons of Arduino, Raspberry Pi and Beagle Bone: <\/strong><br \/> <strong> <\/strong><br \/> <a href=\"http:\/\/blog.makezine.com\/2013\/04\/15\/arduino-uno-vs-beaglebone-vs-raspberry-pi\/\"><strong>http:\/\/blog.makezine.com\/2013\/04\/15\/arduino-uno-vs-beaglebone-vs-raspberry-pi\/<\/strong><\/a> <\/p>\n<p> Our book: &#8220;SolderSmoke &#8212; Global Adventures in Wireless Electronics&#8221; <a href=\"http:\/\/soldersmoke.com\/book.htm\">http:\/\/soldersmoke.com\/book.htm<\/a> Our coffee mugs, T-Shirts, bumper stickers: <a href=\"http:\/\/www.cafepress.com\/SolderSmoke\">http:\/\/www.cafepress.com\/SolderSmoke<\/a> Our Book Store: <a href=\"http:\/\/astore.amazon.com\/contracross-20\">http:\/\/astore.amazon.com\/contracross-20<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve succumbed to the lure of the tiny computers and microprocessors.
