I have been neglecting my Arduino interests in favor of amateur radio recently. So, I bought a book "Arduino for Ham Radio."
One simple project to get me started is a compass display. The book call for a LCD module, which I have, but I also have an +Adafruit Industries OLED 128X64 display that I haven used yet. So, I dug it out, soldered on the header pins, downloaded the Adafruit libraries, and uploaded an example to an +Arduino Uno clone that I had lying around. I'm now sensitive to clones, and from now on will only by genuine Arduinos, but since I had this one I used it.
I made one small change to the program, just for grins: changed "Hello World" to "Hello Town" and passed that message as a variable rather than a literal. No big deal, but I'm refreshing my Arduino skills.
I have ordered the compass module--after I get it I'll finish the project and post results here.
Here's a video.

The J-Pole antenna I built (see this post) is now mounted on the house to serve as my permanent antenna for 2 meters. We sealed the coax connections with electrical tape and soldered the crosspiece with the SO-239 connector to each of the antenna elements to make a permanent electrical connection. The RG-58 coax is connected to a lightning arrestor, and then to another piece of coax via a female-female adapter. Those connections are wrapped with electrical tape, and the coax goes through a hole in the singles and wall into the area above a drop ceiling in my basement, then down the wall and under my desk to my new base station radio (Yaesu FT-1900R, with a 13.8V power supply). The lightning arrestor is connected to a 10ft ground rod, driven into the ground, via #12AWG wire.
It works great!
Next steps: finish studying for my general class license. pass the test, by an HF rig, put up a multiband dipole antenna, and expand my ham horizons.
