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.”
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell with Google Hangouts On-Air is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
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.
