In a recent blog posting, you mentioned the use of Arduinos in the radio hobby. Those of us who have experimented with Arduinos (and Raspberry Pis, etc.) likely have come across Adafruit Industries when looking for hardware bits and pieces to use in our maker activities.
Very cool! Thanks so much, Richard, for sharing this. Adafruit looks like not only a true community player, but a comprehensive source for the electronics experimenter! My daughters love the Adafruit video; now to dig up all of the previous episodes!
