After making the Arduino Fox controller, I decided to take this one a little bit further by adding DTMF decoding to it so the fox could be controlled remotely. The program is much more complicated so I tried to separate the Morse Code section while leaving the DTMF portion of the program in the main Sketch.
The main part is building the circuit and programming the Arduino. At minimum, be sure to change your call sign in the morseCode.h file on line 28. Modify anything else to suit your fancy. Add more DTMF codes for even greater control. The main DTMF code is “51” to start transmitting and “50” to turn off transmitting.
I couldn’t help with the laxative one liner. I had a lot of fun working on this dummy load project. It’s been in my hands for about two years. Frank, K9TIE, sent me the assembled can a few years ago, but I never went to the store to purchase the mineral oil (a laxative). I decided that I would build it since I needed a higher-power capable dummy load. Continue reading DIY 50 Ohm Oil Cooled Dummy Load – A Smooth Move→
I have had quite a few changes lately. I applied for a vanity call sign in July 2013, and I was granted my new call sign and purchased a new house. Many things in life have changed, so now I’m blogging from scratch. If you want to view any of my past adventures, check them out at http://tech-tut.com/ham/.
I’m in a new home, and I live in the city with a tiny yard and neighbors, so things will be much different. Such is the life of a ham that wants to keep the surroundings happy. No more crazy towers and and the like. Everything has to be incognito now.
