The September/October issue of QEX is coming soon, and it is full of theoretical and practical technical articles that you don’t want to miss. Richard Chapman, KC4IFB, shows how to use the Arduino prototyping board to design a project, and then gives us a lesson in programming the microprocessor to “Build a Low-Cost Iambic Keyer Using Open-Source Hardware.” W. G. Moneysmith, W4NFR, was a new repeater trustee needing a duplexer for a 70 cm repeater. He presents his solution in “A Homecrafted Duplexer for the 70 Centimeter Band.”
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
I hope a lot more ‘HAM’ projects are done with the AVR chips and the various Arduino boards. The “Nuts and Volts” magazine has also covered a series of AVR/Butterfly and Arduino hardware/software tools.
QEX has some very nifty stuff, really things at the edge of ham development. Mind, I’m a ham radio operator and I’ve been using arduino for a while now:)
Hey, good catch!
Amateur radio has a very long tradition of open source hardware & software projects.
